Embodiment

[0037] When the flight attitude of the drone changes suddenly, the gyroscope sends out a command signal S to move the servo valve core to the left, because the locking device C has been opened (the opening of the locking device C is caused by the sudden change of the flight attitude of the drone. To), so the pressure oil enters the left chamber of the small hydraulic cylinder I (the first hydraulic cylinder), which makes the piston move to the right. Because the movement resistance of the mechanical input system is much greater than the movement resistance of the spool of servo valve B, the rod 2 immediately rotates around point f, so that the spool of servo valve B moves to the left, and the pressure oil enters the hydraulic cylinder II (the second hydraulic cylinder ) to the left cavity, the piston overcomes the load P and moves to the right, the mechanical feedback of the piston makes the rod 1 rotate around the point a through the rod 3, and the rod 2 rotates around the poi...

Abstract

The invention provides an unmanned aerial vehicle flight process automatic stability augmentation system which comprises a gyroscope connected with an unmanned aerial vehicle flight control module andfurther comprises a load P capable of enabling the flight attitude of an unmanned aerial vehicle to be balanced by moving the position. The movement of the load P is driven by a stability augmentation driving device, and when the flight control module monitors that the change of the flight attitude of the unmanned aerial vehicle has the risk of instability of the unmanned aerial vehicle through the gyroscope, the stability augmentation driving device activates and drives the load P to move. The system can enable the flight attitude of the unmanned aerial vehicle to recover balance when the flight attitude of the unmanned aerial vehicle changes suddenly.

Description

technical field [0001] The invention relates to the technical field of unmanned aerial vehicles, in particular to an automatic stabilization system for an unmanned aerial vehicle during flight. Background technique [0002] When the UAV is performing a flight mission, its flight state must be stable. If the flight state is unstable, it is very easy to crash and cause immeasurable losses. [0003] In order to prevent the instability of the flight process of the UAV, a flight state control system is specially invented to realize the stable flight of the UAV and effectively complete related tasks. Contents of the invention [0004] The invention proposes an automatic stabilization system for the flight process of the UAV, which can restore the balance of the UAV's flight attitude when the UAV's flight attitude changes suddenly. [0005] The present invention adopts the following technical solutions. [0006] The automatic stabilization system of the drone flight process, th...
