Out of the pursuit of high power-to-weight ratio, the pressure flow margin of the civil aircraft hydraulic energy system is relatively small. In order to conduct flow analysis of the hydraulic energy system, the flow requirements of the left and right hydraulic energy system users are counted, and the flow analysis of the hydraulic energy system is carried out under the three major working conditions (normal working conditions, EDP failure and engine failure). First determine the flow supply capacity of EDP and EMP are 175 L/min and 140 L/min and the input conditions of flow analysis, and then analyze the user flow requirements under each flight profile, and finally obtain the Flow analysis results of hydraulic energy system. The results show that the aircraft hydraulic energy system can meet the flow requirements of hydraulic users under normal working conditions and faulty working conditions (EDP failure and engine failure).
