Problems solved by technology

[0002] When the quadrotor aircraft is flying, its blades rotate at a very high speed. Once a failure occurs, the aircraft will lose control and cause different degrees of danger to the user.
[0005] But comparative documents 1 and 2 are still difficult to solve the problem that the drone cannot hover when the fuselage is tilted, so a jet drone and its control method are needed to solve this problem

Description

technical field [0001] The present invention specifically relates to a jet unmanned aerial vehicle, and the present invention also specifically relates to a control method of the jet unmanned aerial vehicle. Background technique [0002] When the quadrotor aircraft is flying, its blades rotate at a very high speed. Once a failure occurs, the aircraft will be out of control, which will cause different degrees of danger to the user. At the same time, when the blade rotates at a high speed, the noise generated by it is very large, causing noise pollution to the environment. In addition, the traditional quadrotor aircraft cannot hover when the fuselage is tilted, but the function of keeping the aircraft fuselage tilted in some special situations and terrains is particularly important. For example, it is not realistic to replace the aircraft in a narrow terrain based on the size of the terrain space. When the aircraft is performing a rescue survey mission, the tilt of the fusela...
