Embodiment Construction

[0016] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention will be further described below in conjunction with specific illustrations.

[0017] Self-adjusting UAV thrust line measurement and adjustment method, see figure 2 As shown, by setting the ball joint 3 between the thrust nozzle 1 and the mounting plate 2, the ball joint 3 can be flexibly rotated within a certain range to solve the coaxial problem of the center axis of the rocket and the center axis of the thrust nozzle. The specific steps are as follows:

[0018] 1) Before the measurement and adjustment, first fix the mounting plate 2 on the aircraft frame plate 4 with screws, and install the ball joint 3 between the thrust nozzle 1 and the mounting plate 2;

[0019] 2) Adjust the ball joint 3 installed in step 1) to ensure that the ball joint 3 can rotate flexibly within a certain range;

[0020] 3) Lift the UAV i...

Abstract

A self-adjusting unmanned aerial vehicle thrust line measurement and adjustment method is characterized in that a ball joint is arranged between a thrust nozzle and a mounting plate, the ball joint drives the thrust nozzle to turn automatically as the ball joint can flexibly turn in a certain range, the position where the central axis of the thrust nozzle is coaxial to the central line of a lifting rope is record, meanwhile a fastening device on the ball joint needs to be screwed, and then the problem of coaxiality of the central axis of a rocket and the central axis of the thrust nozzle is solved. The self-adjusting unmanned aerial vehicle thrust line measurement and adjustment method effectively improves the work efficiency, reduces labor intensity of workers and improves the measurement and adjustment accuracy.

Description

technical field [0001] The invention relates to the technical field of thrust line measurement of an unmanned aerial vehicle, in particular to a self-adjusting method for measuring and adjusting the thrust line of an unmanned aerial vehicle. Background technique [0002] When the UAV is launched, the body is generally placed on the launcher at a certain pitch angle, the booster rocket is on the thrust nozzle, and the booster thrust line (that is, the central axis of the booster rocket) passes through the center of mass of the aircraft to ensure that the aircraft does not roll over; Before launch, the thrust nozzle needs to be adjusted to ensure that the central axis of the thrust nozzle (that is, the extension line) passes through the center of mass of the aircraft, so that the thrust line passes through the center of mass of the aircraft. Ensure that the center axis of the rocket is coaxial with the center axis of the thrust nozzle. However, when traditional UAVs measure a...
