Example Embodiment

[0018] The present invention will be further described below in conjunction with the accompanying drawings and specific embodiments.

[0019] like Figure 1-4 As shown, the vertical take-off and landing UAV vector tension device, the vertical take-off and landing UAV is provided with a body 1, an aileron 2, a vertical tail 3, an engine 4, and a vector tension device 5. The vertical take-off and landing UAV vector tension device includes a swinging engine mount 51, a ball head tie rod 52, a fixed engine mount 53, a control steering gear 54, a ball head connected to an optical axis 55, and a support connected to an optical axis 56. Blue bearing 57, ball joint 58.

[0020] see Figure 1-4 , the fixed engine mount 53 is fixed on the leading edge of the wing of the body 1 through a mechanical connection, the control steering gear 54 is fixed on the fixed engine mount 53 by four screws, and the engine 4 is fixed on the swinging engine mount 51 by bolts Above, the oscillating engine mount 51 is connected to the fixed engine mount 53 through the support connecting the optical axis 56 and the flange bearing 57, so that the swinging engine mount 51 can rotate around the support connecting the optical axis 56 on the fixed engine mount 53, Then a ball head 59 is fixed by connecting the optical axis 55 through the ball head on the side of the swing type engine mount 51, and then a ball head 58 is fixed on the steering gear rocking arm of the control steering gear 54, after determining the position of the ball head pull bar 52 After the length, connect the two fixed ball joints with the ball joint pull rod 52, so that the swing type engine mount 51 can also swing thereupon when the rocking arm of the steering gear is rotated.

[0021] The control method of the vertical take-off and landing UAV equipped with the vector pulling device adopts the vector control of the vector pulling device and the rudder effect produced by the aileron 2 to control the vertical take-off and landing process and the flight process of the vertical take-off and landing UAV, In this way, the vertical take-off and landing UAV can take off and land more smoothly, improving the safety, flexibility and stability of the aircraft.

[0022] figure 1 The middle vertical tail 3 also plays the role of landing gear while making the aircraft have a certain static stability in the left and right (yaw) directions.

[0023] The specific implementation steps of the control method of the vertical take-off and landing UAV vector tension device are as follows:

[0024] 1) When taking off, the vector pulling device 5 enters the fixed mode, the swing engine support 51 remains horizontal, and the vertical pulling force generated by the rotation of the propeller makes the UAV vertically rise rapidly.

[0025] 2) After the UAV reaches the predetermined height, the UAV is controlled by the rudder effect generated by the aileron 2 to change from a vertical attitude to a horizontal attitude, and the vector pulling device 5 is converted to a differential mode. When the aileron 2 regulating the attitude of the UAV fails or exceeds the set threshold, the vector pulling device 5 is activated to assist the aileron 2 to adjust the attitude of the UAV.

[0026] 3) During the transition of the UAV from the flying attitude to the alternate landing attitude, the vector pulling device 5 is set to the synchronous mode. At this moment, the swinging engine mounts 51 of the two vector tension devices on the UAV rotate in the same direction synchronously, and the effect of the UAV attitude change is the same as the effect of adjusting the aileron 2 to make the UAV attitude change in the direction of rotation. To achieve the effect of rapid change of posture.

[0027] 4) During the vertical landing process of the UAV, the control of the vector pulling device 5 enters the mixed mode. In this mode, the swinging engine mounts of the two vector pull devices on the drone rotate in a mixed manner. When the pitch angle of the UAV needs to be adjusted, the swing engine mounts of the two vector pull devices rotate in the same direction; when the roll angle of the UAV needs to be adjusted, the swing engine mounts of the two vector pull devices rotate in the opposite direction .
