The term 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. [16] 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. [17] 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. Similar terms are unmanned-aircraft vehicle system ( UAVS) and remotely piloted aircraft system ( RPAS). [18] Many similar terms are in use. Under new regulations which came into effect 1 June 2019, the term RPAS 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". [19] Classification types [ edit ] Flapping-wing ornithopters, imitating birds or insects, have been flown as microUAVs. Their inherent stealth recommends them for spy missions. a b "NASA's Ingenuity Mars Helicopter Succeeds in Historic First Flight". Mars Exploration Program. NASA. 19 April 2021 .

Program workers at AeroVironment and NASA AMES and Langley research centers brought the total to 150.

The Spanish engineer Leonardo Torres Quevedo introduced a radio-based control-system called the Telekino [35] at the Paris Academy of Science in 1903, as a way of testing an airship of his own design without risking human lives.

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. [23] 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). 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.

River monitoring several methods have been developed to perform flow monitoring using image velocimetry methods which allow to properly describe the 2D flow velocity fields. [151] At the time of the approval of the Mars 2020 program in July 2014, [35] a helicopter flight demonstration was neither scoped nor budgeted. [36] On April 19 it made the first powered, controlled extraterrestrial flight by any aircraft. During its first flight Ingenuity took off vertically, hovered, and then landed. It flew for a total of 39.1seconds during that attempt. [9] [10] [11] As of its 64th flight on October 27, 2023, Ingenuity had flown a total of 1 hour, 57 minutes and 36 seconds over 913 days.

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. The U.S. funded the CTC or counterterror center within the CIA which sought to fight terrorism with the aid of modernized drone technology. [60] In the 1990s, the U.S. DoD gave a contract to 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. An unmanned aerial vehicle ( UAV) is defined as a "powered, aerial vehicle that does not 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". [14] UAV is a term that is commonly applied to military use cases. [15] Missiles with warheads are generally not considered UAVs because the vehicle itself is a munition, but certain types of propeller-based missile are often called " kamikaze drones" by the public and media. Also, the relation of UAVs to remote controlled model aircraft is unclear, [ citation needed] 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 regardless of size. [ citation needed]
Autonomy
As of 2012 [update], the United States Air Force (USAF) employed 7,494 UAVs– almost one in three USAF aircraft. [63] [64] The Central Intelligence Agency also operated UAVs. [65] 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. [66] Due to their wide proliferation, no comprehensive list of UAV systems exists. [64] [67] UAV actuators 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. 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.
