Unmanned aerial vehicle. An unmanned aerial vehicle (UAV), commonly known as a drone, is an aircraft without any human pilot, crew, or passengers on board. UAVs are a component of an unmanned aircraft system (UAS), which includes adding a ground-based controller and a system of communications with the UAV. The flight of UAVs may operate under remote control by a human operator, as remotely-piloted aircraft (RPA), or with various degrees of autonomy, such as autopilot assistance, up to fully autonomous aircraft that have no provision for human intervention.UAVs were originally developed through the twentieth century for military missions too "dull, dirty or dangerous.

Unmanned aerial vehicle. for humans, and by the twenty-first, they had become essential assets to most militaries. As control technologies improved and costs fell, their use expanded to many non-military applications. These include forest fire monitoring, aerial photography, product deliveries, agriculture, policing and surveillance, infrastructure inspections, entertainment, science, smuggling, and drone racing.## Terminology.Many terms are used for aircraft which fly without any persons on board:The term drone has been used from the early days of aviation, being applied to remotely-flown target aircraft used for practice firing of a battleship's guns, such as the 1920s Fairey Queen and 1930s de Havilland Queen Bee. Later.

Unmanned aerial vehicle. examples included the Airspeed Queen Wasp and Miles Queen Martinet, before ultimate replacement by the GAF Jindivik. The term remains in common use. In addition to the software, autonomous drones also employ a host of advanced technologies that allow them to carry out their missions without human intervention, such as cloud computing, computer vision, artificial intelligence, machine learning, deep learning, and thermal sensors. For recreational uses, an aerial photography drone (as opposed to a UAV) is an aircraft that has first-person video, autonomous capabilities, or both.An unmanned aerial vehicle (UAV) is defined as a "powered, aerial vehicle that does not.

Unmanned aerial vehicle. carry a human operator, uses aerodynamic forces to provide vehicle lift, can fly autonomously or be piloted remotely, can be expendable or recoverable, and can carry a lethal or nonlethal payload". UAV is a term that is commonly applied to military use cases. However missiles with warheads are not considered UAVs because the vehicle itself is a munition. Also, the relation of UAVs to remote controlled model aircraft is unclear, UAVs may or may not include remote-controlled model aircraft. Some jurisdictions base their definition on size or weight; however, the US FAA defines any uncrewed flying craft as a UAV.

Unmanned aerial vehicle. regardless of size. The term "unmanned aircraft system" (UAS) was adopted by the United States Department of Defense (DoD) and the United States Federal Aviation Administration (FAA) in 2005 according to their Unmanned Aircraft System Roadmap 2005–2030. The International Civil Aviation Organization (ICAO) and the British Civil Aviation Authority adopted this term, also used in the European Union's Single-European-Sky (SES) Air-Traffic-Management (ATM) Research (SESAR Joint Undertaking) roadmap for 2020. This term emphasizes the importance of elements other than the aircraft. It includes elements such as ground control stations, data links and other support equipment. A similar term is an "unmanned-aircraft.

Unmanned aerial vehicle. vehicle system" (UAVS), "remotely piloted aerial vehicle" (RPAV), "remotely piloted aircraft system" (RPAS). Many similar terms are in use. "Unoccupied" and "uninhabited" are occasionally used as alternatives to "unmanned". Under new regulations which came into effect 1 June 2019, the term RPAS (Remotely Piloted Aircraft System) has been adopted by the Canadian Government to mean "a set of configurable elements consisting of a remotely piloted aircraft, its control station, the command and control links and any other system elements required during flight operation".## Classification types.UAVs may be classified like any other aircraft, according to design configuration such as weight or.

Unmanned aerial vehicle. engine type, maximum flight altitude, degree of operational autonomy, operational role, etc. According to the United States Department of Defense, UAVs are classified into five categories below:Other classifications of UAVs include:## Range and endurance.There are usually five categories when UAVs are classified by range and endurance:## Size.There are usually four categories when UAVs are classified by size, with at least one of the dimensions (length or wingspan) meet the following respective limits:## Weight.Based on their weight, drones can be classified into five categories — nano (weighing up to 250 g), Micro air vehicles (MAV) (250 g – 2 kg), Miniature.

Unmanned aerial vehicle. UAV or small (SUAV) (2–25 kg), medium (25–150 kg), and large (over 150 kg).## Degree of autonomy.Drones could also be classified based on the degree of autonomy in their flight operations. ICAO classifies uncrewed aircraft as either remotely piloted aircraft or fully autonomous. Some UAVs offer intermediate degrees of autonomy. For example, a vehicle may be remotely piloted in most contexts but have an autonomous return-to-base operation. Some aircraft types may optionally fly manned or as UAVs, which may include manned aircraft transformed into uncrewed or Optionally Piloted UAVs (OPVs).## Altitude.Based on the altitude, the following UAV classifications have been.

Unmanned aerial vehicle. Carrier Guidance System (CACGS) for UAVs## Composite criteria.An example of classification based on the composite criteria is U.S. Military's unmanned aerial systems (UAS) classification of UAVs based on weight, maximum altitude and speed of the UAV component.## History.## Early drones.The earliest recorded use of an unmanned aerial vehicle for warfighting occurred in July 1849, with a balloon carrier (the precursor to the aircraft carrier) in the first offensive use of air power in naval aviation. Austrian forces besieging Venice attempted to launch some 200 incendiary balloons at the besieged city. The balloons were launched mainly from land; however, some were.

Unmanned aerial vehicle. also launched from the Austrian ship . At least one bomb fell in the city; however, due to the wind changing after launch, most of the balloons missed their target, and some drifted back over Austrian lines and the launching ship "Vulcano".The Spanish engineer Leonardo Torres y Quevedo introduced a radio-based control-system called the "Telekino" at the Paris Academy of Science in 1903 with the intention of testing an airship of his own design without risking human lives.Significant development of drones started in the 1900s, and originally focused on providing practice targets for training military personnel. The earliest attempt at.

Unmanned aerial vehicle. a powered UAV was A. M. Low's "Aerial Target" in 1916. Low confirmed that Geoffrey de Havilland's monoplane was the one that flew under control on 21 March 1917 using his radio system. Following this successful demonstration in the spring of 1917 Low was transferred to develop aircraft controlled fast motor launches D.C.B.s with the Royal Navy in 1918 intended to attack shipping and port installations and he also assisted Wing Commander Brock in preparations for the Zeebrugge Raid. Other British unmanned developments followed, leading to the fleet of over 400 de Havilland 82 Queen Bee aerial targets that went.

Unmanned aerial vehicle. in the late 1930s.## World War II.In 1940 Denny started the Radioplane Company and more models emerged during World War II used both to train antiaircraft gunners and to fly attack-missions. Nazi Germany produced and used various UAV aircraft during the war, like the Argus As 292 and the V-1 flying bomb with a jet engine.## Postwar period.After World War II development continued in vehicles such as the American JB-4 (using television/radio-command guidance), the Australian GAF Jindivik and Teledyne Ryan Firebee I of 1951, while companies like Beechcraft offered their Model 1001 for the U.S. Navy in 1955. Nevertheless, they.

Unmanned aerial vehicle. were little more than remote-controlled airplanes until the Vietnam War.In 1959 the U.S. Air Force, concerned about losing pilots over hostile territory, began planning for the use of uncrewed aircraft. Planning intensified after the Soviet Union shot down a U-2 in 1960. Within days, a highly-classified UAV program started under the code name of "Red Wagon". The August 1964 clash in the Tonkin Gulf between naval units of the U.S. and the North Vietnamese Navy initiated America's highly-classified UAVs (Ryan Model 147, Ryan AQM-91 Firefly, Lockheed D-21) into their first combat missions of the Vietnam War. When the Chinese government.

Unmanned aerial vehicle. showed photographs of downed U.S. UAVs via "Wide World Photos", the official U.S. response was "no comment".During the War of Attrition (1967–1970) in the Middle East, Israeli intelligence tested the first tactical UAVs installed with reconnaissance cameras, which successfully returned photos from across the Suez Canal. This was the first time that tactical UAVs that could be launched and landed on any short runway (unlike the heavier jet-based UAVs) were developed and tested in battle.In the 1973 Yom Kippur War, Israel used UAVs as decoys to spur opposing forces into wasting expensive anti-aircraft missiles. After the 1973 Yom Kippur war,.

Unmanned aerial vehicle. a few key people from the team that developed this early UAV joined a small startup company that aimed to develop UAVs into a commercial product, eventually purchased by Tadiran and leading to the development of the first Israeli UAV.In 1973 the U.S. military officially confirmed that they had been using UAVs in Southeast Asia (Vietnam). Over 5,000 U.S. airmen had been killed and over 1,000 more were missing or captured. The USAF 100th Strategic Reconnaissance Wing flew about 3,435 UAV missions during the war at a cost of about 554 UAVs lost to all causes. In the words of.

Unmanned aerial vehicle. USAF General George S. Brown, Commander, Air Force Systems Command, in 1972, "The only reason we need (UAVs) is that we don't want to needlessly expend the man in the cockpit." Later that year, General John C. Meyer, Commander in Chief, Strategic Air Command, stated, "we let the drone do the high-risk flying ... the loss rate is high, but we are willing to risk more of them ...they save lives!"During the 1973 Yom Kippur War, Soviet-supplied surface-to-air missile-batteries in Egypt and Syria caused heavy damage to Israeli fighter jets. As a result, Israel developed the IAI Scout as the.

Unmanned aerial vehicle. first UAV with real-time surveillance. The images and radar decoys provided by these UAVs helped Israel to completely neutralize the Syrian air defenses at the start of the 1982 Lebanon War, resulting in no pilots downed. In Israel in 1987, UAVs were first used as proof-of-concept of super-agility, post-stall controlled flight in combat-flight simulations that involved tailless, stealth-technology-based, three-dimensional thrust vectoring flight-control, and jet-steering.## Modern UAVs.With the maturing and miniaturization of applicable technologies in the 1980s and 1990s, interest in UAVs grew within the higher echelons of the U.S. military. In the 1990s, the U.S. DoD gave a contract to.

Unmanned aerial vehicle. AAI Corporation along with Israeli company Malat. The U.S. Navy bought the AAI Pioneer UAV that AAI and Malat developed jointly. Many of these UAVs saw service in the 1991 Gulf War. UAVs demonstrated the possibility of cheaper, more capable fighting-machines, deployable without risk to aircrews. Initial generations primarily involved surveillance aircraft, but some carried armaments, such as the General Atomics MQ-1 Predator, that launched AGM-114 Hellfire air-to-ground missiles.CAPECON, a European Union project to develop UAVs, ran from 1 May 2002 to 31 December 2005. the United States Air Force (USAF) employed 7,494 UAVs almost one in three USAF aircraft.

Unmanned aerial vehicle. The Central Intelligence Agency also operated UAVs. By 2013 at least 50 countries used UAVs. China, Iran, Israel, Pakistan, Turkey, and others designed and built their own varieties. The use of drones has continued to increase. Due to their wide proliferation, no comprehensive list of UAV systems exists.The development of smart technologies and improved electrical-power systems led to a parallel increase in the use of drones for consumer and general aviation activities. As of 2021, quadcopter drones exemplify the widespread popularity of hobby radio-controlled aircraft and toys, however the use of UAVs in commercial and general aviation is limited by.

Unmanned aerial vehicle. a lack of autonomy and by new regulatory environments which require line-of-sight contact with the pilot.In 2020 a Kargu 2 drone hunted down and attacked a human target in Libya, according to a report from the UN Security Council's Panel of Experts on Libya, published in March 2021. This may have been the first time an autonomous killer-robot armed with lethal weaponry attacked human beings.Superior drone technology played a role in Azerbaijan's successes in the 2020 Nagorno-Karabakh war against Armenia.UAVs are also used in NASA missions. The Dragonfly spacecraft is being developed, and is aiming to reach and examine Saturn's.

Unmanned aerial vehicle. moon Titan. Its primary goal is to roam around the surface, expanding the amount of area to be researched previously seen by Landers. As a UAV, Dragonfly allows examination of potentially diverse types of soil. The drone is set to launch in 2027, and is estimated to take a seven more years to reach the Saturnian system.## Design.Crewed and uncrewed aircraft of the same type generally have recognizably similar physical components. The main exceptions are the cockpit and environmental control system or life support systems. Some UAVs carry payloads (such as a camera) that weigh considerably less than an adult.

Unmanned aerial vehicle. human, and as a result, can be considerably smaller. Though they carry heavy payloads, weaponized military UAVs are lighter than their crewed counterparts with comparable armaments.Small civilian UAVs have no life-critical systems, and can thus be built out of lighter but less sturdy materials and shapes, and can use less robustly tested electronic control systems. For small UAVs, the quadcopter design has become popular, though this layout is rarely used for crewed aircraft. Miniaturization means that less-powerful propulsion technologies can be used that are not feasible for crewed aircraft, such as small electric motors and batteries.Control systems for UAVs are.

Unmanned aerial vehicle. often different than crewed craft. For remote human control, a camera and video link almost always replace the cockpit windows; radio-transmitted digital commands replace physical cockpit controls. Autopilot software is used on both crewed and uncrewed aircraft, with varying feature sets.## Aircraft configuration.The primary difference from manned aeroplanes is the lack of need for a cockpit area and its windows. However some types are adapted from piloted examples, or are designed for optional piloted or unmanned operational modes. Air safety is also less of a critical requirement for unmanned aircraft, allowing the designer greater freedom to experiment. These two factors.

Unmanned aerial vehicle. have led to a great variety of airframe and engine configurations in UAVs.For conventional flight the flying wing and blended wing body offer light weight combined with low drag and stealth, and are popular configurations. Larger types which carry a variable payload are more likely to feature a distinct fuselage with a tail for stability, control and trim, although the wing configurations in use vary widely.For vertical flight, the tailless quadcopter requires a relatively simple control system and is common for smaller UAVs. However the mechanism does not scale well to larger aircraft, which tend to use a conventional single.

Unmanned aerial vehicle. rotor with collective and cyclic pitch control, along with a stabilising tail rotor.## Propulsion.Traditional internal combustion and jet engines remain in use for drones requiring long range. However for shorter-range missions electric power has almost entirely taken over. The distance record for a UAV (built from balsa wood and mylar skin) across the North Atlantic Ocean is held by a gasoline model airplane or UAV. Manard Hill "in 2003 when one of his creations flew 1,882 miles across the Atlantic Ocean on less than a gallon of fuel" holds this record.Besides the traditional piston engine, the Wankel rotary engine is.

Unmanned aerial vehicle. used by some drones. This type offers high power output for lower weight, with quieter and more vibration-free running. Claims have also been made for improved reliability and greater range.Small drones mostly use lithium-polymer batteries (Li-Po), while some larger vehicles have adopted the a hydrogen fuel cell. The energy density of modern Li-Po batteries is far less than gasoline or hydrogen. However electric motors are cheaper, lighter and quieter. Complex multi-engine, multi-propeller installations are under development with the goal of improving aerodynamic and propulsive efficiency. For such complex power installations, Battery elimination circuitry (BEC) may be used to centralize power.

Unmanned aerial vehicle. distribution and minimize heating, under the control of a microcontroller unit (MCU).## Ornithopters – wing propulsion.Flapping-wing ornithopters, imitating birds or insects, have been flown as microUAVs. Their inherent stealth recommends them for spy missions.Sub-1g microUAVs inspired by flies, albeit using a power tether, have been able to "land" on vertical surfaces. Other projects mimic the flight of beetles and other insects.## Computer control systems.UAV computing capability followed the advances of computing technology, beginning with analog controls and evolving into microcontrollers, then system-on-a-chip (SOC) and single-board computers (SBC).System hardware for small UAVs is often called the flight controller (FC), flight controller.

Unmanned aerial vehicle. board (FCB) or autopilot.## Architecture.## Sensors.Position and movement sensors give information about the aircraft state. Exteroceptive sensors deal with external information like distance measurements, while exproprioceptive ones correlate internal and external states.Non-cooperative sensors are able to detect targets autonomously so they are used for separation assurance and collision avoidance.Degrees of freedom (DOF) refers to both the amount and quality of sensors on board: 6 DOF implies 3-axis gyroscopes and accelerometers (a typical inertial measurement unit IMU), 9 DOF refers to an IMU plus a compass, 10 DOF adds a barometer and 11 DOF usually adds a GPS receiver.## Actuators.UAV actuators.

Unmanned aerial vehicle. include digital electronic speed controllers (which control the RPM of the motors) linked to motors/engines and propellers, servomotors (for planes and helicopters mostly), weapons, payload actuators, LEDs and speakers.## Software.UAV software called the flight stack or autopilot. The purpose of the flight stack is to obtain data from sensors, control motors to ensure UAV stability, and facilitate ground control and mission planning communication.UAVs are real-time systems that require rapid response to changing sensor data. As a result, UAVs rely on single-board computers for their computational needs. Examples of such single-board computers include Raspberry Pis, Beagleboards, etc. shielded with NavIO, PXFMini,.

Unmanned aerial vehicle. etc. or designed from scratch such as NuttX, preemptive-RT Linux, Xenomai, Orocos-Robot Operating System or DDS-ROS 2.0.Civil-use open-source stacks include: Agilicious (also open-source hardware) ArduCopter CrazyFlie KKMultiCopter MultiWii BaseFlight (forked from MultiWii) CleanFlight (forked from BaseFlight) BetaFlight (forked from CleanFlight) iNav (forked from CleanFlight) RaceFlight (forked from CleanFlight) OpenPilot dRonin (forked from OpenPilot) LibrePilot (forked from OpenPilot) TauLabs (forked from OpenPilot) Paparazzi PX4 autopilot DroneCode (Umbrella organization managing PX4 within the Linux Foundation)Due to the open-source nature of UAV software, they can be customized to fit specific applications. For example, researchers from the Technical University of Košice have replaced the.

Unmanned aerial vehicle. default control algorithm of the PX4 autopilot. This flexibility and collaborative effort has led to a large number of different open-source stacks, some of which are forked from others, such as CleanFlight, which is forked from BaseFlight and from which three other stacks are forked from.## Loop principles.UAVs employ open-loop, closed-loop or hybrid control architectures. Open loop This type provides a positive control signal (faster, slower, left, right, up, down) without incorporating feedback from sensor data. Closed loop This type incorporates sensor feedback to adjust behavior (reduce speed to reflect tailwind, move to altitude 300 feet). The PID controller is.

Unmanned aerial vehicle. common. Sometimes, feedforward is employed, transferring the need to close the loop further.## Communications.UAVs use a radio for control and exchange of video and other data. Early UAVs had only narrowband uplink. Downlinks came later. These bi-directional narrowband radio links carried command and control (C&C) and telemetry data about the status of aircraft systems to the remote operator.In most modern UAV applications, video transmission is required. So instead of having separate links for C&C, telemetry and video traffic, a broadband link is used to carry all types of data. These broadband links can leverage quality of service techniques and carry.

Unmanned aerial vehicle. TCP/IP traffic that can be routed over the Internet.The radio signal from the operator side can be issued from either: Ground control – a human operating a radio transmitter/receiver, a smartphone, a tablet, a computer, or the original meaning of a military ground control station (GCS). Remote network system, such as satellite duplex data links for some military powers. Downstream digital video over mobile networks has also entered consumer markets, while direct UAV control uplink over the cellular mesh and LTE have been demonstrated and are in trials. Another aircraft, serving as a relay or mobile control station military manned-unmanned.

Unmanned aerial vehicle. teaming (MUM-T).Modern networking standards have explicitly considered drones and therefore include optimizations. The 5G standard has mandated reduced user plane latency to 1ms while using ultra-reliable and low-latency communications.## Autonomy.The level of autonomy in UAVs varies widely. UAV manufacturers often build in specific autonomous operations, such as: Self-level: attitude stabilization on the pitch and roll axes. Altitude hold: The aircraft maintains its altitude using barometric pressure and/or GPS data. Hover/position hold: Keep level pitch and roll, stable yaw heading and altitude while maintaining position using GNSS or inertial sensors. Headless mode: Pitch control relative to the position of the pilot.

Unmanned aerial vehicle. Performance considerations.## Flight envelope.UAVs can be programmed to perform aggressive maneuvers or landing/perching on inclined surfaces, and then to climb toward better communication spots. Some UAVs can control flight with varying flight modelisation, such as VTOL designs.UAVs can also implement perching on a flat vertical surface.## Endurance.UAV endurance is not constrained by the physiological capabilities of a human pilot.Because of their small size, low weight, low vibration and high power to weight ratio, Wankel rotary engines are used in many large UAVs. Their engine rotors cannot seize; the engine is not susceptible to shock-cooling during descent and it does not.

Unmanned aerial vehicle. require an enriched fuel mixture for cooling at high power. These attributes reduce fuel usage, increasing range or payload.Proper drone cooling is essential for long-term drone endurance. Overheating and subsequent engine failure is the most common cause of drone failure.Hydrogen fuel cells, using hydrogen power, may be able to extend the endurance of small UAVs, up to several hours.Micro air vehicles endurance is so far best achieved with flapping-wing UAVs, followed by planes and multirotors standing last, due to lower Reynolds number.Solar-electric UAVs, a concept originally championed by the AstroFlight Sunrise in 1974, have achieved flight times of several weeks.Solar-powered.

Unmanned aerial vehicle. atmospheric satellites ("atmosats") designed for operating at altitudes exceeding 20 km (12 miles, or 60,000 feet) for as long as five years could potentially perform duties more economically and with more versatility than low Earth orbit satellites. Likely applications include weather monitoring, disaster recovery, Earth imaging and communications.Electric UAVs powered by microwave power transmission or laser power beaming are other potential endurance solutions.Another application for a high endurance UAV would be to "stare" at a battlefield for a long interval (ARGUS-IS, Gorgon Stare, Integrated Sensor Is Structure) to record events that could then be played backwards to track battlefield activities.##.

Unmanned aerial vehicle. Reliability.Reliability improvements target all aspects of UAV systems, using resilience engineering and fault tolerance techniques.Individual reliability covers robustness of flight controllers, to ensure safety without excessive redundancy to minimize cost and weight. Besides, dynamic assessment of flight envelope allows damage-resilient UAVs, using non-linear analysis with ad hoc designed loops or neural networks. UAV software liability is bending toward the design and certifications of crewed avionics software.Swarm resilience involves maintaining operational capabilities and reconfiguring tasks given unit failures.## Applications.In recent years, autonomous drones have begun to transform various application areas as they can fly beyond visual line of sight (BVLOS) while.

Unmanned aerial vehicle. maximizing production, reducing costs and risks, ensuring site safety, security and regulatory compliance, and protecting the human workforce in times of a pandemic. They can also be used for consumer-related missions like package delivery, as demonstrated by Amazon Prime Air, and critical deliveries of health supplies.There are numerous civilian, commercial, military, and aerospace applications for UAVs. These include:General: Recreation, Disaster relief, archeology, conservation of biodiversity and habitat, law enforcement, crime, and terrorism. Commercial: Aerial surveillance, filmmaking, journalism, scientific research, surveying, cargo transport, mining, manufacturing, Forestry, solar farming, thermal energy, ports and agriculture.## Warfare.With extensive cost reductions and advancements in the.

Unmanned aerial vehicle. UAVs technology, the defense forces around the globe are increasingly using these for various applications such as surveillance, logistics, communication, attack and combat.As of 2020, seventeen countries have armed UAVs, and more than 100 countries use UAVs in a military capacity. The global military UAV market is dominated by companies based in the United States, Turkey, China, Israel and Iran. By sale numbers, the US held over 60% military-market share in 2017. Top military UAV manufactures are including General Atomics, Lockheed Martin, Northrop Grumman, Boeing, Baykar, TAI, IAIO, CASC and CAIG. China has established and expanded its presence in military.

Unmanned aerial vehicle. UAV market since 2010. Turkey also established and expanded its presence in military UAV market.Of the 18 countries that are known to have received military drones between 2010 to 2019, the top 12 all purchased their drones from China. According to a report of 2015, Israeli companies mainly focus on small surveillance UAV systems and by quantity of drones, Israel exported 60.7% (2014) of UAV on the market while the United States export 23.9% (2014). Between 2010 and 2014, there were 439 drones exchanged compared to 322 in the five years previous to that, among these only small fraction of.

Unmanned aerial vehicle. overall trade – just 11 (2.5%) of the 439 are armed drones. The US alone operated over 9,000 military UAVs in 2014; among them more than 7000 are RQ-11 Raven miniature UAVs. General Atomics is the dominant manufacturer with the Global Hawk and Predator/Mariner systems product-line.For intelligence and reconnaissance missions, the inherent stealth of micro UAV flapping-wing ornithopters, imitating birds or insects, offers potential for covert surveillance and makes them difficult targets to bring down.UAVs are used for reconnaissance, attack, demining, and target practice.## Civil.The civilian (commercial and general) drone market is dominated by Chinese companies. Chinese drone manufacturer DJI.

Unmanned aerial vehicle. alone had 74% of the civil market share in 2018, with no other company accounting for more than 5%, and with $11 billion forecast global sales in 2020. Following increased scrutiny of its activities, the US Interior Department grounded its fleet of DJI drones in 2020, while the Justice Department prohibited the use of federal funds for the purchase of DJI and other foreign made UAVs. DJI is followed by Chinese company Yuneec, US company 3D Robotics and French company Parrot with a significant gap in market share. As of May 2021, 873,576 UAVs have been registered with the US.

Unmanned aerial vehicle. FAA, of which 42% are categorized as commercial drones and 58% as recreational drones. 2018 NPD point to consumers increasingly purchasing drones with more advanced features with 33 percent growth in both the $500+ and $1000+ market segments.The civil UAV market is relatively new compared to the military one. Companies are emerging in both developed and developing nations at the same time. Many early stage startups have received support and funding from investors as is the case in the United States and by government agencies as is the case in India. Some universities offer research and training programs or degrees.

Unmanned aerial vehicle. Private entities also provide online and in-person training programs for both recreational and commercial UAV use.Consumer drones are also widely used by military organizations worldwide because of the cost-effective nature of consumer product. In 2018, Israeli military started to use DJI Mavic and Matrice series of UAV for light reconnaissance mission since the civil drones are easier to use and have higher reliability. DJI drones is also the most widely used commercial unmanned aerial system that the US Army has employed. DJI surveillance drones have also been used by Chinese police in Xinjiang since 2017.The global UAV market will reach.

Unmanned aerial vehicle. US$21.47 billion, with the Indian market touching the US$885.7 million mark, by 2021.Lighted drones are beginning to be used in nighttime displays for artistic and advertising purposes.## Aerial photography.Drones are ideally suited to capturing aerial shots in photography and cinematography, and are widely used for this purpose. Small drones avoid the need for precise coordination between pilot and cameraman, with the same person taking on both roles. However, big drones with professional cine cameras, there is usually a drone pilot and a camera operator who controls camera angle and lens. For example, the AERIGON cinema drone which is used in.

Unmanned aerial vehicle. film production in big blockbuster movies is operated by 2 people. Drones provide access to dangerous, remote or otherwise inaccessible sites.## Agriculture and forestry.As global demand for food production grows exponentially, resources are depleted, farmland is reduced, and agricultural labor is increasingly in short supply, there is an urgent need for more convenient and smarter agricultural solutions than traditional methods, and the agricultural drone and robotics industry is expected to make progress. Agricultural drones have been used in areas such as Africa to help build sustainable agriculture.The use of UAVs is also being investigated to help detect and fight wildfires,.

Unmanned aerial vehicle. whether through observation or launching pyrotechnic devices to start backfires.## Law enforcement.Police can use drones for applications such as search and rescue and traffic monitoring.## Safety and security.## Threats.## Nuisance.UAVs can threaten airspace security in numerous ways, including unintentional collisions or other interference with other aircraft, deliberate attacks or by distracting pilots or flight controllers. The first incident of a drone-airplane collision occurred in mid-October 2017 in Quebec City, Canada. The first recorded instance of a drone collision with a hot air balloon occurred on 10 August 2018 in Driggs, Idaho, United States; although there was no significant damage to.

Unmanned aerial vehicle. the balloon nor any injuries to its 3 occupants, the balloon pilot reported the incident to the National Transportation Safety Board, stating that "I hope this incident helps create a conversation of respect for nature, the airspace, and rules and regulations". Unauthorized UAV flights into or near major airports have prompted extended shutdowns of commercial flights.Drones caused significant disruption at Gatwick Airport during December 2018, needing the deployment of the British Army.In the United States, flying close to a wildfire is punishable by a maximum $25,000 fine. Nonetheless, in 2014 and 2015, firefighting air support in California was hindered on.

Unmanned aerial vehicle. several occasions, including at the Lake Fire and the North Fire. In response, California legislators introduced a bill that would allow firefighters to disable UAVs which invaded restricted airspace. The FAA later required registration of most UAVs.## Security vulnerabilities.By 2017, drones were being used to drop contraband into prisons.The interest in UAVs cyber security has been raised greatly after the Predator UAV video stream hijacking incident in 2009, where Islamic militants used cheap, off-the-shelf equipment to stream video feeds from a UAV. Another risk is the possibility of hijacking or jamming a UAV in flight. Several security researchers have made.

Unmanned aerial vehicle. public some vulnerabilities in commercial UAVs, in some cases even providing full source code or tools to reproduce their attacks. At a workshop on UAVs and privacy in October 2016, researchers from the Federal Trade Commission showed they were able to hack into three different consumer quadcopters and noted that UAV manufacturers can make their UAVs more secure by the basic security measures of encrypting the Wi-Fi signal and adding password protection.## Aggression.UAVs could be loaded with dangerous payloads, and crashed into vulnerable targets. Payloads could include explosives, chemical, radiological or biological hazards. UAVs with generally non-lethal payloads could possibly.

Unmanned aerial vehicle. be hacked and put to malicious purposes. Anti-UAV systems are being developed by states to counter this threat. This is, however, proving difficult. As Dr J. Rogers stated in an interview to A&T "There is a big debate out there at the moment about what the best way is to counter these small UAVs, whether they are used by hobbyists causing a bit of a nuisance or in a more sinister manner by a terrorist actor".## Countermeasures.## Counter unmanned air system.The malicious use of UAVs has led to the development of counter unmanned air system (C-UAS) technologies. Automatic tracking and.

Unmanned aerial vehicle. detection of UAVs from commercial cameras have become accurate thanks to the development of deep learning based machine learning algorithms. It is also possible to automatically identify UAVs across different cameras with different view points and hardware specification with re-identification methods.

Calvatia gigantea. Calvatia gigantea, commonly known as the giant puffball, is a puffball mushroom commonly found in meadows, fields, and deciduous forests usually in late summer and autumn. It is found in temperate areas throughout the world.## Description.Most giant puffballs grow to be 10 to 50 (cm), sometimes to be 90 (cm) in diameter; although occasionally some can reach diameters up to 150 (cm) and weights of 20 (kg). The inside of mature giant puffballs is greenish brown, whereas the interior of immature puffballs is white. The large white mushrooms are edible when young.The fruiting body of a puffball mushroom will develop.

Calvatia gigantea. within the period of a few weeks and soon begin to decompose and rot, at which point it is dangerous to eat. Unlike most mushrooms, all the spores of the giant puffball are created inside the fruiting body; large specimens can easily contain several trillion spores. Spores are yellowish, smooth, and 3–5 μm in size.The classification of this species has been revised in recent years, as the formerly recognized class Gasteromycetes, which included all puffballs, has been found to be polyphyletic. Some authors place the giant puffball and other members of genus "Calvatia" in order Agaricales. Also, the species has.

Calvatia gigantea. in the past been placed in two other genera, "Lycoperdon" and "Langermannia". However, the current view is that the giant puffball is "Calvatia".## Conservation status.The giant puffball is widespread and common in the UK. It is protected in parts of Poland and is of conservation concern in Norway.## Cooking.All true puffballs are considered edible when immature, but can cause digestive upset if the spores have begun to form, as indicated by the color of the flesh being not pure white (first yellow, then brown). Immature gilled species still contained within their universal veil can be look alikes for puffballs. To.

Calvatia gigantea. distinguish puffballs from poisonous fungi, they must be cut open; edible puffballs will have a solid white interior. Some similar mushrooms have the white interior (or yellowish) but also have the silhouette of a cap-type mushroom on the interior when cut open. These are young cap-type mushrooms and may be poisonous.## Medical uses.Puffballs are a known styptic and have long been used as wound dressing, either in powdered form or as slices 3 cm thick. The fungus was often harvested prior to battles for this purpose.It is the main source of the anti-tumor mucoprotein calvacin, which is present only in.

The latter are distinguished by a much firmer, elastic fruiting body, and having an interior that becomes dark purplish-black with white reticulation early in development. "Scleroderma citrinum" is poisonous and may cause mild intoxication. Video footage of mature Giant Puffballs The Giant Puffball VOLATILES OF THE GIANT PUFFBALL MUSHROOM (Calvatia gigantea).

Blenheim Palace. Blenheim Palace (pronounced ) is a country house in Woodstock, Oxfordshire, England. It is the seat of the Dukes of Marlborough and the only non-royal, non-episcopal country house in England to hold the title of palace. The palace, one of England's largest houses, was built between 1705 and 1722, and designated a UNESCO World Heritage Site in 1987.The palace is named after the 1704 Battle of Blenheim, and thus ultimately after Blindheim (also known as Blenheim) in Bavaria. It was originally intended to be a reward to John Churchill, 1st Duke of Marlborough for his military triumphs against the French.

Blenheim Palace. and Bavarians in the War of the Spanish Succession, culminating in the Battle of Blenheim. The land was given as a gift, and construction began in 1705, with some financial support from Queen Anne. The project soon became the subject of political infighting, with the Crown cancelling further financial support in 1712, Marlborough's three-year voluntary exile to the Continent, the fall from influence of his duchess, and lasting damage to the reputation of the architect Sir John Vanbrugh.Designed in the rare, and short-lived, English Baroque style, architectural appreciation of the palace is as divided today as it was in the.

Blenheim Palace. 1720s. It is unique in its combined use as a family home, mausoleum and national monument. The palace is notable as the birthplace and ancestral home of Sir Winston Churchill.Following the palace's completion, it became the home of the Churchill (later Spencer-Churchill) family for the next 300 years, and various members of the family have wrought changes to the interiors, park and gardens. At the end of the 19th century, the palace was saved from ruin by funds gained from the 9th Duke of Marlborough's marriage to American railroad heiress Consuelo Vanderbilt.## Churchills.John Churchill was born in Devon. Although his.

Blenheim Palace. family had aristocratic relations, it belonged to the minor gentry rather than the upper echelons of 17th-century society. In 1678, Churchill married Sarah Jennings, and in April that year, he was sent by Charles II to The Hague to negotiate a convention on the deployment of the English army in Flanders. The mission ultimately proved abortive. In May, Churchill was appointed to the temporary rank of Brigadier-General of Foot, but the possibility of a continental campaign was eliminated with the Treaty of Nijmegen. When Churchill returned to England, the Popish Plot resulted in a temporary three-year banishment for James Stuart,.

Blenheim Palace. Duke of York. The Duke obliged Churchill to attend him, first to The Hague, then in Brussels. For his services during the crisis, Churchill was made Lord Churchill of Eyemouth in the peerage of Scotland in 1682, and the following year appointed colonel of the King's Own Royal Regiment of Dragoons.On the death of Charles II in 1685, his brother, the Duke of York, became King James II. James had been Governor of the Hudson's Bay Company (today North America's oldest company, established by royal charter in 1670), and with his succession to the throne, Churchill was appointed the company's.

Blenheim Palace. third ever governor. He had also been affirmed Gentleman of the Bedchamber in April, and admitted to the English peerage as Baron Churchill of Sandridge in the county of Hertfordshire in May. Following the Monmouth Rebellion, Churchill was promoted to Major General and awarded the lucrative colonelcy of the Third Troop of Life Guards. When William, Prince of Orange, invaded England in November 1688, Churchill, accompanied by some 400 officers and men, rode to join him in Axminster. When the King saw he could not even keep Churchill—for so long his loyal and intimate servant—he fled to France. As part.

Blenheim Palace. of William III's coronation honours, Churchill was created Earl of Marlborough, sworn to the Privy Council, and made a Gentleman of the King's Bedchamber.During the War of the Spanish Succession Churchill gained a reputation as a capable military commander, and in 1702 he was elevated to the dukedom of Marlborough. During the war he won a series of victories, including the Battle of Blenheim (1704), the Battle of Ramillies (1706), the Battle of Oudenarde (1708), and the Battle of Malplaquet (1709). For his victory at Blenheim, the Crown bestowed upon Marlborough the tenancy of the royal manor of Hensington (situated.

Blenheim Palace. on the site of Woodstock) to site the new palace, and Parliament voted a substantial sum of money towards its creation. The rent or "petit serjeanty" due to the Crown for the land was set at the peppercorn rent or quit-rent of one copy of the French royal flag to be tendered to the Monarch annually on the anniversary of the Battle of Blenheim. This flag is displayed by the Monarch on a 17th-century French writing table in Windsor Castle.Marlborough's wife was by all accounts a cantankerous woman, though capable of great charm. She had befriended the young Princess Anne.

Blenheim Palace. and later, when the princess became Queen, the Duchess of Marlborough, as Her Majesty's Mistress of the Robes, exerted great influence over the Queen on both personal and political levels. The relationship between Queen and Duchess later became strained and fraught, and following their final quarrel in 1711, the money for the construction of Blenheim ceased. For political reasons the Marlboroughs went into exile on the Continent until they returned the day after the Queen's death on 1 August 1714.## Site.The estate given by the nation to Marlborough for the new palace was the manor of Woodstock, sometimes called the.

Blenheim Palace. Palace of Woodstock, which had been a royal demesne, in reality little more than a deer park. Legend has obscured the manor's origins. King Henry I enclosed the park to contain the deer. Henry II housed his mistress Rosamund Clifford (sometimes known as "Fair Rosamund") there in a "bower and labyrinth"; a spring in which she is said to have bathed remains, named after her. It seems the unostentatious hunting lodge was rebuilt many times, and had an uneventful history until Elizabeth I, before her succession, was imprisoned there by her half-sister Mary I between 1554 and 1555. Elizabeth had.

Blenheim Palace. been implicated in the Wyatt plot, but her imprisonment at Woodstock was short, and the manor remained in obscurity until bombarded and ruined by Oliver Cromwell's troops during the Civil War. When the park was being re-landscaped as a setting for the Palace, the 1st Duchess wanted the historic ruins demolished, while Vanbrugh, an early conservationist, wanted them restored and made into a landscape feature. The Duchess, as so often in her disputes with her architect, won the day and the remains of the manor were swept away.## Architect.The architect selected for the ambitious project was a controversial one. The.

Blenheim Palace. Duchess was known to favour Sir Christopher Wren, famous for St Paul's Cathedral and many other national buildings. The Duke however, following a chance meeting at a playhouse, is said to have commissioned Sir John Vanbrugh there and then. Vanbrugh, a popular dramatist, was an untrained architect, who usually worked in conjunction with the trained and practical Nicholas Hawksmoor. The duo had recently completed the first stages of the Baroque Castle Howard. This huge Yorkshire mansion was one of England's first houses in the flamboyant European Baroque style. The success of Castle Howard led Marlborough to commission something similar at.

Blenheim Palace. Woodstock.Blenheim, however, was not to provide Vanbrugh with the architectural plaudits he imagined it would. The fight over funding led to accusations of extravagance and impracticality of design, many of these charges levelled by the Whig factions in power. He found no defender in the Duchess of Marlborough. Having been foiled in her wish to employ Wren, she levelled criticism at Vanbrugh on every level, from design to taste. In part their problems arose from what was demanded of the architect. The nation (which was then assumed, by both architect and owners, to be paying the bills) wanted a monument,.

Blenheim Palace. but the Duchess wanted not only a fitting tribute to her husband but also a comfortable home, two requirements that were not compatible in 18th-century architecture. Finally, in the early days of the building the Duke was frequently away on his military campaigns, and it was left to the Duchess to negotiate with Vanbrugh. More aware than her husband of the precarious state of the financial aid they were receiving, she criticised Vanbrugh's grandiose ideas for their extravagance.Following their final altercation, Vanbrugh was banned from the site. In 1719, whilst the Duchess was away, Vanbrugh viewed the palace in secret.

Blenheim Palace. However, when Vanbrugh's wife visited the completed Blenheim as a member of the viewing public in 1725, the Duchess refused to allow her even to enter the park.Vanbrugh's severe massed Baroque used at Blenheim never truly caught the public imagination, and was quickly superseded by the revival of the Palladian style. Vanbrugh's reputation was irreparably damaged, and he received no further truly great public commissions. For his final design, Seaton Delaval Hall in Northumberland, which was hailed as his masterpiece, he used a refined version of the Baroque employed at Blenheim. He died shortly before its completion.## Funding the construction.The.

Blenheim Palace. precise responsibility for the funding of the new palace has always been a debatable subject, unresolved to this day. The palace as a reward was mooted within months of the Battle of Blenheim, at a time when Marlborough was still to gain many further victories on behalf of the country. That a grateful nation led by Queen Anne wished and intended to give their national hero a suitable home is beyond doubt, but the exact size and nature of that house is questionable. A warrant dated 1705, signed by the parliamentary treasurer the Earl of Godolphin, appointed Vanbrugh as architect.

Blenheim Palace. and outlined his remit. Unfortunately for the Churchills, nowhere did this warrant mention Queen or Crown.The Duke of Marlborough contributed £60,000 to the initial cost when work commenced in 1705, which, supplemented by Parliament, should have built a monumental house. Parliament voted funds for the building of Blenheim, but no exact sum was mentioned nor provision for inflation or over-budget expenses. Almost from the outset, funds were spasmodic. Queen Anne paid some of them, but with growing reluctance and lapses, following her frequent altercations with the Duchess. After their final argument in 1712, all state money ceased and work came.

Blenheim Palace. to a halt. £220,000 had already been spent and £45,000 was owing to workmen. The Marlboroughs were forced into exile on the continent, and did not return until after the Queen's death in 1714.On their return the Duke and Duchess came back into favour at court. The 64-year-old Duke now decided to complete the project at his own expense. In 1716 work resumed, but the project relied completely upon the limited means of the Duke himself. Harmony on the building site was short-lived, as in 1717 the Duke suffered a severe stroke, and the thrifty Duchess took control. The Duchess.

Blenheim Palace. blamed Vanbrugh entirely for the growing costs and extravagance of the palace, the design of which she had never liked. Following a meeting with the Duchess, Vanbrugh left the building site in a rage, insisting that the new masons, carpenters and craftsmen, brought in by the Duchess, were inferior to those he had employed. The master craftsmen he had patronised, however, such as Grinling Gibbons, refused to work for the lower rates paid by the Marlboroughs. The craftsmen brought in by the Duchess, under the guidance of furniture designer James Moore, and Vanbrugh's assistant architect Hawksmoor, completed the work in.

Blenheim Palace. perfect imitation of the greater masters.Following the Duke's death in 1722, completion of the palace and its park became the Duchess's driving ambition. Vanbrugh's assistant Hawksmoor was recalled and in 1723 designed the "Arch of Triumph", based on the Arch of Titus, at the entrance to the park from Woodstock. Hawksmoor also completed the interior design of the library, the ceilings of many of the state rooms and other details in numerous other minor rooms, and various outbuildings. Cutting rates of pay to workmen, and using lower-quality materials in unobtrusive places, the widowed Duchess completed the great house as a.

Blenheim Palace. tribute to her late husband. The final date of completion is not known, but as late as 1735 the Duchess was haggling with Rysbrack over the cost of Queen Anne's statue placed in the library. In 1732 the Duchess wrote "The Chappel is finish'd and more than half the Tomb there ready to set up".## Design and architecture.Vanbrugh planned Blenheim in perspective; that is, to be best viewed from a distance. As the site covers some seven acres (28,000 m2) this is also a necessity.The plan of the palace's principal block (or corps de logis) is a rectangle ("see plan").

Blenheim Palace. pierced by two courtyards; these serve as little more than light wells. Contained behind the southern facade are the principal state apartments; on the east side are the suites of private apartments of the Duke and Duchess, and on the west along the entire length of the "piano nobile" is given a long gallery originally conceived as a picture gallery, but is now the library. The corps de logis is flanked by two further service blocks around square courtyards ("not shown in the plan"). The east court contains the kitchens, laundry, and other domestic offices, the west court adjacent to.

Blenheim Palace. the chapel the stables and indoor riding school. The three blocks together form the "Great Court" designed to overpower the visitor arriving at the palace. Pilasters and pillars abound, while from the roofs, themselves resembling those of a small town, great statues in the Renaissance manner of St Peter's in Rome gaze down on the visitor below, who is rendered inconsequential. Other assorted statuary in the guise of martial trophies decorate the roofs, most notably Britannia standing atop the entrance pediment in front of two reclining chained French captives sculpted in the style of Michelangelo, and the English lion devouring.

Blenheim Palace. the French cock, on the lower roofs. Many of these are by such masters as Grinling Gibbons.In the design of great 18th-century houses comfort and convenience were subservient to magnificence, and this is certainly the case at Blenheim. This magnificence over creature comfort is heightened as the architect's brief was to create not only a home but also a national monument to reflect the power and civilisation of the nation. To create this monumental effect, Vanbrugh chose to design in a severe Baroque style, using great masses of stone to imitate strength and create shadow as decoration.The solid and huge.

Blenheim Palace. entrance portico on the north front resembles more the entrance to a pantheon than a family home. Vanbrugh also liked to employ what he called his "castle air", which he achieved by placing a low tower at each corner of the central block and crowning the towers with vast belvederes of massed stone, decorated with curious finials (disguising the chimneys). Coincidentally these towers, which hint at the pylons of an Egyptian temple, further add to the heroic pantheonesque atmosphere of the building.There are two approaches to the palace's grand entrance, one from the long straight drive through wrought iron gates.

Blenheim Palace. directly into the Great Court; the other, equally if not more impressive, betrays Vanbrugh's true vision: the palace as a bastion or citadel, the true monument and home to a great warrior. Piercing the windowless, city-like curtain wall of the east court is the great East Gate, a monumental triumphal arch, more Egyptian in design than Roman. An optical illusion was created by tapering its walls to create an impression of even greater height. Confounding those who accuse Vanbrugh of impracticality, this gate is also the palace's water tower. Through the arch of the gate one views across the courtyard.

Blenheim Palace. a second equally massive gate, that beneath the clock tower, through which one glimpses the Great Court.This view of the Duke as an omnipotent being is also reflected in the interior design of the palace, and indeed its axis to certain features in the park. It was planned that when the Duke dined in state in his place of honour in the great saloon, he would be the climax of a great procession of architectural mass aggrandising him rather like a proscenium. The line of celebration and honour of his victorious life began with the great column of victory surmounted.

Blenheim Palace. by his statue and detailing his triumphs, and the next point on the great axis, planted with trees in the position of troops, was the epic Roman style bridge. The approach continues through the great portico into the hall, its ceiling painted by James Thornhill with the Duke's apotheosis, then on under a great triumphal arch, through the huge marble door-case with the Duke's marble effigy above it (bearing the ducal plaudit "Nor could Augustus better calm mankind"), and into the painted saloon, the most highly decorated room in the palace, where the Duke was to have sat enthroned.The Duke.

Blenheim Palace. was to have sat with his back to the great 30-tonne marble bust of his vanquished foe Louis XIV, positioned high above the south portico. Here the defeated King was humiliatingly forced to look down on the great parterre and spoils of his conqueror (rather in the same way as severed heads were displayed generations earlier). The Duke did not live long enough to see this majestic tribute realised, and sit enthroned in this architectural vision. The Duke and Duchess moved into their apartments on the eastern side of the palace, but the entirety was not completed until after the.

Blenheim Palace. Duke's death.The palace has been Grade I listed on the National Heritage List for England since August 1957.## Palace chapel.The palace chapel, as a consequence of the Duke's death, now obtained even greater importance. The design was altered by the Marlboroughs' friend the Earl of Godolphin, who placed the high altar in defiance of religious convention against the west wall, thus allowing the dominating feature to be the Duke's gargantuan tomb and sarcophagus. Commissioned by the Duchess in 1730, it was designed by William Kent, and statues of the Duke and Duchess depicted as Caesar and Caesarina adorn the great.

Blenheim Palace. sarcophagus. In bas relief at the base of the tomb, the Duchess ordered to be depicted the surrender of Marshal Tallard. However, the theme throughout the palace of honouring the Duke did not reach its apotheosis until the dowager duchess's death in 1744. Then, the Duke's coffin was returned to Blenheim from its temporary resting place, Westminster Abbey, and husband and wife were interred together and the tomb erected and completed. Now Blenheim had indeed become a pantheon and mausoleum. Successive Dukes and their wives are also interred in the vault beneath the chapel. Other members of family are interred.

Blenheim Palace. in St. Martin's parish churchyard at Bladon, a short distance from the palace.## Interior.The internal layout of the rooms of the central block at Blenheim was defined by the court etiquette of the day. State apartments were designed as an axis of rooms of increasing importance and public use, leading to the chief room. The larger houses, like Blenheim, had two sets of state apartments each mirroring each other. The grandest and most public and important was the central saloon "("B" in the plan") which served as the communal state dining room. To either side of the saloon are suites.

Blenheim Palace. of state apartments, decreasing in importance but increasing in privacy: the first room "("C")" would have been an audience chamber for receiving important guests, the next room "("L")" a private withdrawing room, the next room "("M")" would have been the bedroom of the occupier of the suite, thus the most private. One of the small rooms between the bedroom and the internal courtyard was intended as a dressing room. This arrangement is reflected on the other side of the saloon. The state apartments were intended for use by only the most important guests such as a visiting sovereign. On the.

Blenheim Palace. left (east) side of the plan on either side of the bow room "(marked "O")" can be seen a smaller but nearly identical layout of rooms, which were the suites of the Duke and Duchess themselves. Thus, the bow room corresponds exactly to the saloon in terms of its importance to the two smaller suites.Blenheim Palace was the birthplace of the 1st Duke's famous descendant, Winston Churchill, whose life and times are commemorated by a permanent exhibition in the suite of rooms in which he was born "(marked "K" on the plan)". Blenheim Palace was designed with all its principal.

Blenheim Palace. and secondary rooms on the "piano nobile", thus there is no great staircase of state: anyone worthy of such state would have no cause to leave the "piano nobile". Insofar as Blenheim does have a grand staircase, it is the series of steps in the Great Court which lead to the North Portico. There are staircases of various sizes and grandeur in the central block, but none are designed on the same scale of magnificence as the palace. James Thornhill painted the ceiling of the hall in 1716. It depicts Marlborough kneeling to Britannia and proffering a map of the.

Blenheim Palace. Battle of Blenheim. The hall is 67 (ft) high, and remarkable chiefly for its size and for its stone carvings by Gibbons, yet in spite of its immense size it is merely a vast anteroom to the saloon.The saloon was also to have been painted by Thornhill, but the Duchess suspected him of overcharging, so the commission was given to Louis Laguerre. This room is an example of three-dimensional painting, or "trompe l'œil", "trick-the-eye", a fashionable painting technique at the time. The Peace Treaty of Utrecht was about to be signed, so all the elements in the painting represent the.

Blenheim Palace. coming of peace. The domed ceiling is an allegorical representation of Peace: John Churchill is in the chariot, he holds a zigzag thunderbolt of war, and the woman who holds back his arm represents Peace. The walls depict all the nations of the world who have come together peacefully. Laguerre also included a self-portrait placing himself next to Dean Jones, chaplain to the 1st Duke, another enemy of the Duchess, although she tolerated him in the household because he could play a good hand at cards. To the right of the doorway leading into the first stateroom, Laguerre included the.

Blenheim Palace. French spies, said to have big ears and eyes because they may still be spying. Of the four marble door-cases in the room displaying the Duke's crest as a prince of the Holy Roman Empire, only one is by Gibbons, the other three were copied indistinguishably by the Duchess's cheaper craftsmen.The third remarkable room is the long library designed by Nicholas Hawksmoor in 1722–1725, "(H)", 183 (ft) long, which was intended as a picture gallery. The ceiling has saucer domes, which were to have been painted by Thornhill, had the Duchess not upset him. The palace, and in particular this.

Blenheim Palace. room, was furnished with the many valuable artefacts the Duke had been given, or sequestered as the spoils of war, including a fine art collection. Here in the library, rewriting history in her own indomitable style, the Duchess set up a larger than life statue of Queen Anne, its base recording their friendship.From the northern end of the library—in which is housed the largest pipe organ in private ownership in Europe, built by England's great organ builder Henry Willis & Sons—access is obtained to the raised colonnade which leads to the chapel "(H)". The chapel is perfectly balanced on the.

Blenheim Palace. eastern side of the palace by the vaulted kitchen. This symmetrical balancing and equal weight given to both spiritual and physical nourishment would no doubt have appealed to Vanbrugh's renowned sense of humour, if not the Duchess'. The distance of the kitchen from even the private dining room "("O" on the plan)" was obviously of no consideration, hot food being of less importance than to avoid having to inhale the odour of cooking and proximity of servants.## Pipe organs.The Long Library organ was built in 1891 by the famous London firm of Henry Willis & Sons at a cost of.

Blenheim Palace. £3,669. It replaced a previous organ built in 1888 by Isaac Abbott of Leeds, which was removed to St Swithun's church, Hither Green. Originally erected in the central bay, with its back to the water terraces, the Norwich firm of Norman & Beard moved it to the northwestern end of the library in 1902 and made a few tonal additions and, the following year, cleaned it. No further changes were made until 1930, when the Willis firm lowered the pitch to modern concert pitch: a Welte automatic player was added in 1931, with 70 rolls cut by Marcel Dupré, Joseph.

Blenheim Palace. Bonnet, Alfred Hollins, Edwin Lemare and Harry Goss-Custard also being supplied. This remained in use for some time: the Duke of the time is said to have frequently sat at the organ bench and pretended to play the organ to his guests and they would applaud at the end. This practice is said to have been halted abruptly when the player started before the Duke had reached the organ. This famous instrument is regularly maintained and is played by visiting organists throughout the year, but its condition is declining: a fundraising campaign has been launched for its complete restoration.The organ.

Blenheim Palace. in the chapel was built circa 1853 by Robert Postill of York: it is notable as a rare unaltered example of this fine builder's work, speaking boldly and clearly into a generous acoustic.## Park and gardens.Blenheim sits in the centre of a large undulating park, a classic example of the English landscape garden movement and style. When Vanbrugh first cast his eyes over it in 1704 he immediately conceived a typically grandiose plan: through the park trickled the small River Glyme, and Vanbrugh envisaged this marshy brook traversed by the "finest bridge in Europe". Thus, ignoring the second opinion offered.

Blenheim Palace. by Sir Christopher Wren, the marsh was channelled into three small canal-like streams and across it rose a bridge of huge proportions, so huge it was reported to contain some 30-odd rooms. While the bridge was indeed an amazing wonder, in this setting it appeared incongruous, causing Alexander Pope to comment: "the minnows, as under this vast arch they pass, murmur, 'how like whales we look, thanks to your Grace.'"Horace Walpole saw it in 1760, shortly before Capability Brown's improvements: "the bridge, like the beggars at the old duchess's gate, begs for a drop of water and is refused." Another.

Blenheim Palace. of Vanbrugh's schemes was the great parterre, nearly half a mile long and as wide as the south front. Also in the park, completed after the 1st Duke's death, is the "Column of Victory". It is 134 (ft) high and terminates a great avenue of elms leading to the palace, which were planted in the positions of Marlborough's troops at the Battle of Blenheim. Vanbrugh had wanted an obelisk to mark the site of the former royal manor, and the trysts of Henry II which had taken place there, causing the 1st Duchess to remark, "If there were obelisks to.

Blenheim Palace. bee made of all what our Kings have done of that sort, the countrey would bee stuffed with very odd things" ("sic"). The obelisk was never realised.Following the 1st Duke's death the Duchess concentrated most of her considerable energies on the completion of the palace itself, and the park remained relatively unchanged until the arrival of Capability Brown in 1764. The 4th Duke employed Brown who immediately began an English landscape garden scheme to naturalise and enhance the landscape, with tree planting, and man-made undulations. However, the feature with which he is forever associated is the lake, a huge stretch.

The lake was narrowed at the point of Vanbrugh's grand bridge, but the three small canal-like streams trickling underneath it were completely absorbed by one river-like stretch. Brown's great achievement at this point was to actually flood and submerge beneath the water level the lower stories and rooms of the bridge itself, thus reducing its incongruous height and achieving what is regarded by many as the epitome of an English landscape. Brown also grassed over the great parterre.

The 5th Duke was responsible for several other garden follies and novelties.Sir William Chambers, assisted by John Yenn, was responsible for the small summerhouse known as "The Temple of Diana" down by the lake, where in 1908 Winston Churchill proposed to his future wife.The extensive landscaped park, woodlands and formal gardens of Blenheim are Grade I listed on the Register of Historic Parks and Gardens.

Blenheim Palace. both his sons were dead, he was succeeded by his daughter Henrietta. This was an unusual succession and required a special Act of Parliament, as only sons can usually succeed to an English dukedom. When Henrietta died, the title passed to Marlborough's grandson Charles Spencer, Earl of Sunderland, whose mother was Marlborough's second daughter Anne.The 1st Duke, as a soldier, was not a rich man and what fortune he possessed was mostly used for finishing the palace. In comparison with other British ducal families, the Marlboroughs were not very wealthy. Yet they existed quite comfortably until the time of the.

Blenheim Palace. 5th Duke of Marlborough (1766–1840), a spendthrift who considerably depleted the family's remaining fortune. He was eventually forced to sell other family estates, but Blenheim was safe from him as it was entailed. This did not prevent him selling the Marlboroughs' Boccaccio for a mere £875 and his own library in over 4000 lots. On his death in 1840, his profligacy left the estate and family with financial problems.By the 1870s, the Marlboroughs were in severe financial trouble and in 1875 the 7th Duke sold the "Marriage of Cupid and Psyche", together with the famed Marlborough gems, at auction for.

Blenheim Palace. £10,000. However this was not enough to save the family. In 1880, the 7th Duke was forced to petition Parliament to break the protective entail on the Palace and its contents. This was achieved under the Blenheim Settled Estates Act 1880 and the door was now open for wholesale dispersal of Blenheim and its contents. The first victim was the great Sunderland Library which was sold in 1882, including such volumes as "The Epistles of Horace", printed at Caen in 1480, and the works of Josephus, printed at Verona in 1648. The 18,000 volumes raised almost £60,000. The sales continued.

Blenheim Palace. to denude the palace: Raphael's "Ansidei Madonna" was sold for £70,000; Van Dyck's Equestrian Portrait of Charles I realised £17,500; and finally the "pièce de résistance" of the collection, Peter Paul Rubens' "Rubens, His Wife Helena Fourment, and Their Son Peter Paul, and Their Son Frans (1633–1678)", which had been given by the city of Brussels to the 1st Duke in 1704, was also sold, and is now in the Metropolitan Museum of Art in New York City.These sums of money, vast by the standards of the day, failed to cover the debts and the maintenance of the great palace.

Blenheim Palace. remained beyond the Marlboroughs' resources. These had always been small in relation to their ducal rank and the size of their house. The British agricultural depression, which started in the 1870s, added to the family's problems. When the 9th Duke inherited in 1892, the land was generating dwindling income.## 9th Duke of Marlborough.Charles, 9th Duke of Marlborough (1871–1934) can be credited with saving both the palace and the family. Inheriting the near-bankrupt dukedom in 1892, he was forced to find a quick and drastic solution to the problems. Prevented by the strict social dictates of late 19th-century society from earning.

Blenheim Palace. money, he was left with one solution: he had to marry into money. In November 1896 he coldly and openly without love married the American railroad heiress Consuelo Vanderbilt. The marriage was celebrated following lengthy negotiations with her divorced parents: her mother, Alva Vanderbilt, was desperate to see her daughter a duchess, and the bride's father, William Vanderbilt, paid for the privilege. The final price was $2,500,000 ($ million today) in 50,000 shares of the capital stock of the Beech Creek Railway Company with a minimum 4% dividend guaranteed by the New York Central Railroad Company. The couple were given.

Blenheim Palace. a further annual income each of $100,000 for life. The teenage Consuelo had been locked in her room by her mother until she agreed to the marriage. The marriage settlement was actually signed in the vestry of St. Thomas Episcopal Church, New York, immediately after the wedding vows had been made. In the carriage leaving the church, Marlborough told Consuelo he loved another woman, and would never return to America, as he "despised anything that was not British".The replenishing of Blenheim began on the honeymoon itself, with the replacement of the Marlborough gems. Tapestries, paintings and furniture were bought in.

Blenheim Palace. Europe to fill the depleted palace. On their return the Duke began an exhaustive restoration and redecoration of the palace. The state rooms to the west of the saloon were redecorated with gilt boiseries in imitation of Versailles. Vanbrugh's subtle rivalry to Louis XIV's great palace was now completely undermined, as the interiors became mere pastiches of those of the greater palace. While this redecoration may not have been without fault (and the Duke later regretted it), other improvements were better received. Another problem caused by the redecoration was that the state and principal bedrooms were now moved upstairs, thus.

Blenheim Palace. rendering the state rooms an enfilade of rather similar and meaningless drawing rooms. On the west terrace the French landscape architect Achille Duchêne was employed to create a water garden. On a second terrace below this were placed two great fountains in the style of Bernini, scaled models of those in the Piazza Navona which had been presented to the 1st Duke.Blenheim was once again a place of wonder and prestige. However, Consuelo was far from happy; she records many of her problems in her cynical and often less than candid biography "The Glitter and the Gold". In 1906 she.

She died in 1964, having lived to see her son become Duke of Marlborough, and frequently returning to Blenheim, the house she had hated and yet saved, albeit as the unwilling sacrifice.After his divorce the Duke married again, to a former friend of Consuelo, Gladys Deacon, another American. This eccentric lady was of an artistic disposition, and a painting of her eyes still remains on the ceiling of the great north portico ("see secondary lead image"). A lower terrace was decorated with sphinxes.

Before her marriage while staying with the Marlboroughs she had caused a diplomatic incident by encouraging the young Crown Prince Wilhelm of Germany to form an attachment. The prince had given her an heirloom ring, which the combined diplomatic services of two empires were charged to recover. After her marriage, Gladys was in the habit of dining with the Duke with a revolver by the side of her plate. Tiring of her, the Duke was temporarily forced to close Blenheim, and turn off the utilities to drive her out.

Blenheim Palace. They subsequently separated but did not divorce. The Duke died in 1934 and his widow in 1977.The 9th Duke was succeeded by his and Consuelo Vanderbilt's eldest son: John, 10th Duke of Marlborough (1897–1972), who after eleven years as a widower, remarried at the age of 74, to (Frances) Laura Charteris, formerly the wife of the 2nd Viscount Long and the 3rd Earl of Dudley, and granddaughter of the 11th Earl of Wemyss. The marriage was short-lived, however; the Duke died just six weeks later, on 11 March 1972. The bereaved Duchess complained of "the gloom and inhospitality of Blenheim.
