Description

 Pushing device for air intake pipe of UAV aircraft

 [0001] The present invention relates to a push device for an air intake pipe of a UAV aircraft.

 Background technique

 [0002] The drone is referred to as "UAV", abbreviated as "UAV", and is a non-manned aircraft operated by radio remote control equipment and self-contained program control devices. From the technical point of view, it can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing machines [1], unmanned airships, unmanned helicopters, unmanned multi-rotor aircraft, unmanned umbrellas, etc. UAVs can be divided into military and civilian applications according to the application field. In military terms, drones are divided into reconnaissance planes and drones. Civilian, drone + industry application, is the real need for drones; currently in aerial photography, agriculture, plant protection, micro-self-timer, express delivery, disaster relief, observation of wildlife, surveillance of infectious diseases, mapping, news reports, power patrol The application of inspection, disaster relief, film and television shooting, manufacturing romance, etc. has greatly expanded the use of the drone itself, and developed countries are also actively expanding the application and development of drone technology. In November 2013, the Civil Aviation Administration of China (CA) issued the Interim Provisions on the Administration of Drivers for Civil Unmanned Aerial Vehicle Systems. The China AOPA Association is responsible for the management of civil drones. According to the "Regulations", the operation of UAVs in China can be divided into 11 cases according to the size of the aircraft and the flight space. Among them, only 116 kg or more and 4,600 m above are flying in the converged airspace. In other cases, other flights, including the increasingly popular micro-aviation aircraft, are managed by industry associations or by the operator.
