Background
Drones tend to be more suitable for tasks that are too "fool, dirty, or dangerous" than manned aircraft. Unmanned aerial vehicles can be classified into military and civil applications according to the application field. For military use, unmanned aerial vehicles divide into reconnaissance aircraft and target drone. In the civil aspect, the unmanned aerial vehicle + industry is applied, and is really just needed by the unmanned aerial vehicle. At present, the unmanned aerial vehicle is applied to the fields of aerial photography, agriculture, plant protection, miniature self-timer, express transportation, disaster relief, wild animal observation, infectious disease monitoring, surveying and mapping, news reporting, power inspection, disaster relief, film and television shooting, romantic manufacturing and the like, the application of the unmanned aerial vehicle is greatly expanded, and developed countries actively expand industrial application and develop unmanned aerial vehicle technology.
Categorised according to the usage, unmanned aerial vehicle can be divided into for military use unmanned aerial vehicle and civilian unmanned aerial vehicle. Military unmanned aerial vehicles can be divided into reconnaissance unmanned aerial vehicles, decoy unmanned aerial vehicles, electronic countermeasure unmanned aerial vehicles, communication relay unmanned aerial vehicles, unmanned fighters, target drone and the like; civilian unmanned aerial vehicles can be divided into patrol/watch on unmanned aerial vehicles, agricultural unmanned aerial vehicles, meteorological unmanned aerial vehicles, exploration unmanned aerial vehicles, surveying and mapping unmanned aerial vehicles, and the like. By scale classification (civil aviation regulations), unmanned aerial vehicles can be divided into micro unmanned aerial vehicles, light unmanned aerial vehicles, small unmanned aerial vehicles and large unmanned aerial vehicles. The micro unmanned aerial vehicle is an unmanned aerial vehicle with the mass of an air machine less than or equal to 7kg, the mass of a light unmanned aerial vehicle more than 7kg but less than or equal to 116kg, and the corrected airspeed is less than 100km/h (55nmile/h) and the lift limit is less than 3000m in full-horsepower flat flight. The small unmanned aerial vehicle is an unmanned aerial vehicle with the mass of the air aircraft less than or equal to 5700kg, except for micro and light unmanned aerial vehicles. Large-scale unmanned aerial vehicle is that the empty quick-witted quality is greater than 5700 kg.
