Thermal analysis and temperature prediction of aviation hydraulic pump

Conduct research on the influencing factors of thermal characteristics of aircraft hydraulic pumps and temperature prediction through simulation experiments and machine learning.First, the basic situation of the aviation hydraulic pump is briefly described. The AMESim simulation software is used to establish a thermal characteristics simulation model of the aviation hydraulic pump. This model can simulate the temperature changes of the hydraulic pump under the full flight profile and analyze the main factors affecting the temperature changes. Then the thermal characteristics simulation analysis of the aircraft hydraulic energy system to which the hydraulic pump belongs was carried out, a heat dissipation plan was designed and analyzed and verified. Finally, the temperature changes of the hydraulic pump are predicted through the machine learning model. The work performed can calculate the operating temperature of the aviation hydraulic pump and hydraulic energy system, guide the system heat dissipation design, and improve the efficiency of aircraft thermal design.
