The main function of the horizontal stabilizer is to ensure the stability of the aircraft during flight by adjusting the pitch angle of the aircraft, and the actuator, as the driving device of the horizontal stabilizer, is responsible for adjusting the angle of the tail wing, thereby achieving precise control of the flight attitude. In the process of research and production of aircraft, the performance test of horizontal stabilizer actuator is crucial.
