With the development of high-speed and high-pressure hydraulic energy systems for civil aircraft, the useless power of the system increases, resulting in a sharp increase in the temperature of the hydraulic energy system. Excessive temperature will not only cause the viscosity of the oil to drop, increase the amount of leakage in the system, but also cause many problems such as increased oil oxidation. In this study, the thermal analysis of the civil aircraft hydraulic energy system under fault conditions is carried out. First, the principle of the civil aircraft hydraulic energy system is analyzed to determine the hydraulic energy system architecture and the thermal analysis input conditions. Calculate the parameters and set the parameters in the software. Finally, perform simulation analysis to obtain the temperature change laws of each area, and summarize the simulation results. The research conclusion provides a theoretical reference for the temperature design and optimization of the civil aircraft hydraulic energy system.
