Technical Field

Background

An unmanned aircraft, abbreviated as "drone", and abbreviated in english as "UAV", is an unmanned aircraft that is operated by a radio remote control device and a self-contained program control device, or is operated autonomously, either completely or intermittently, by an onboard computer. [1]

Drones tend to be more suitable for tasks that are too "fool, dirty, or dangerous" than are 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 + the industry application 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.

An unmanned aerial vehicle, abbreviated as "unmanned aerial vehicle" ("UAV"), is an unmanned aerial vehicle that is operated using a radio remote control device and a self-contained program control device. Unmanned aerial vehicles are in fact a general term for unmanned aerial vehicles, and can be defined from a technical perspective as follows: unmanned fixed wing aircraft, unmanned VTOL aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned paravane, etc. Compared with manned aircraft, it has the advantages of small volume, low cost, convenient use, low requirement on the operational environment, strong battlefield viability and the like. Since the unmanned aircraft has important significance for future air battles, the research and development work of the unmanned aircraft is carried out in all major military countries in the world.

The vertical take-off and landing fixed wing unmanned aerial vehicle needs to perform a series of complex work such as compass calibration, check before flying and the like before flying, and the work is performed by adopting a manual handheld aircraft.

Currently, compass calibration requires that the aircraft be placed on the ground and one end of the aircraft wing is held by a crew member to rotate around the longitudinal axis of the aircraft at a constant speed. The method has the advantages of low calibration efficiency, time and labor waste and certain abrasion to the bottom of the airplane.

Attitude checking in the pre-flight checking work requires the aircraft to perform pitching and yawing operations. The existing operation method is that the aircraft is held by the aircraft to generate pitching and yawing actions, so that the attitude is checked. The method is easy to cause the unmanned aerial vehicle to fall down, and the unmanned aerial vehicle can cause personal injury to the crew if misoperation occurs in the powered-on state.

Meanwhile, when the unmanned aerial vehicle flies in a fixed wing mode, the head of the unmanned aerial vehicle is required to face the upwind direction, and therefore the head of the unmanned aerial vehicle is required to face well before taking off. In the traditional method, a crew manually rotates an airplane to enable the airplane to face correctly, so that time and labor are wasted, and potential safety hazards exist.
