technical field

Background technique

Unmanned aerial vehicle is referred to as "unmanned aerial vehicle", and the English abbreviation is "UAV". [1]

Drones tend to be better suited for tasks that are too "dumb, dirty or dangerous" than manned aircraft. UAVs can be divided into military and civilian according to the application field. In terms of military use, UAVs are divided into reconnaissance aircraft and target aircraft. In terms of civil use, drones + industrial applications are the real needs of drones; currently, they are used in aerial photography, agriculture, plant protection, miniature selfies, express transportation, disaster rescue, observation of wildlife, monitoring of infectious diseases, surveying and mapping, news reports, and electric power patrols. The application in the fields 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 industrial applications and developing drone technology.

Unmanned aerial vehicle, referred to as "unmanned aerial vehicle" ("UAV"), is an unmanned aerial vehicle operated by radio remote control equipment and its own program control device. Unmanned aerial vehicle is actually a general term for unmanned aerial vehicle, which can be divided into: unmanned fixed-wing aircraft, unmanned vertical take-off and landing aircraft, unmanned airship, unmanned helicopter, unmanned multi-rotor aircraft, unmanned Paragliders etc. Compared with manned aircraft, it has the advantages of small size, low cost, convenient use, low requirements for the combat environment, and strong battlefield survivability. Since unmanned aircraft is of great significance to future air combat, major military countries in the world are stepping up the development of unmanned aircraft.

Among them, the vertical take-off and landing fixed-wing UAV needs to perform a series of complex tasks such as compass calibration and pre-flight inspection before taking off.

At present, the compass calibration operation requires the aircraft to be placed on the ground, and one end of the wing held by the maintenance staff rotates around the longitudinal axis of the aircraft at a constant speed. This method is not only inefficient for calibration, time-consuming and labor-intensive, but also causes a certain degree of wear on the bottom of the aircraft.

The attitude inspection in the pre-flight inspection work needs to make the aircraft generate forward and backward pitch and left and right yaw movements. At present, the operation method is to hold the aircraft to make it generate forward and backward pitch and left and right yaw movements, so as to carry out attitude check. This method is easy to cause the drone to fall, and if the drone operates incorrectly in the power-on state, it will cause personal injury to the aircraft.

At the same time, the UAV needs to face the headwind when it is switched to the fixed-wing mode, so the UAV needs to adjust the nose orientation before taking off. The traditional method is to manually turn the aircraft to make it face the correct direction, which is not only time-consuming and labor-intensive, but also has potential safety hazards.
