Aiming at the problem that the detection accuracy of aircraft hydraulic power system declines under complex and changeable working conditions, based on the structure and unit refinement model of aircraft hydraulic power system, the dynamic characteristics of the hydraulic power system are numerically simulated, and the sample data cluster is obtained. The test design method is used to design and verify the detection accuracy and fault detection of aircraft hydraulic power system, finally, the detection performance is verified in the built experimental environment of the aircraft hydraulic assist system. The experimental results show that the designed method can quickly improve the dynamic response ability of the detection system of the aircraft hydraulic assist system and enhance the aircraft handling stability.
