Problems solved by technology

[0002] In the currently used rotor-type UAV equipment, the rotor mechanism is often installed on the side surface of the fuselage or directly on any position of the front, rear and upper surfaces of the fuselage through the connecting beam. The aircraft provides the lift required for flight to meet the needs of UAV flight operations, but on the one hand, the structure of the UAV’s lift body is fixed, and the direction of the lift of the UAV cannot be flexibly adjusted according to the airflow changes during flight. On the one hand, the operating energy consumption of UAVs is relatively high when flying, and on the other hand, the ability to adjust and adapt to complex airflow environments is poor when UAVs are flying, which seriously affects the flexibility and reliability of UAVs. At the same time, the traditional rotor layout method, on the one hand, needs to add extra weight to the UAV, which affects the effective carrying capacity of the UAV. The low utilization rate of space inside the equipment seriously affects the carrying capacity of UAV equipment and the flexibility of carrying operations. At the same time, the connection between lift system equipment such as rotors and drive engines of UAV equipment and the fuselage is relatively fixed. Therefore, when the lift system needs to be replaced, maintained and overhauled, it is difficult to remove and install, and the work efficiency is low, which seriously affects the efficiency of UAV equipment troubleshooting and the continuity and stability of UAV equipment operation.
