Integrated Aircraft Thermal Management System Modelling and Simulated Analysis

Abstract

In order to improve the thermal energy utilization efficiency of aircraft, an integrated thermal management system model using endothermic fuel has been created in AMESIM. The system includes several thermal subsystems such as environment control system, the hydraulic equipment and power equipment cooling system, and anti-icing/de-icing system. The fuel oil was chosen for heat sink and it could cool the exothermic thermal system and transmit the energy to anti-icing/de-icing system in case of icing. Several simulation examples including three atmospheric conditions were accomplished. The results indicated that the present system had the ability to reuse the waste heat meanwhile all the thermal system worked normally. The anti-icing/de-icing didn’t need additional energy which realized less energy consumption. In addition, the model has the ability to facilitate the analysis and optimization of thermal systems on board.
