With the development of electronic integration technology, the heating power of airborne electronic equipment increases gradually, thus the demand for cooling is higher and higher. Meanwhile, the aerodynamic heating effect of supersonic makes the cooling capacity of air as heat sink limited. In order to meet the requirements of the flight mission with Mach numbers from 1 to 4.4, an adaptive power and thermal management system is proposed, which can efficiently manage the heat by taking the external duct air and fuel as heat sink, taking engine bleed air and ram air as refrigeration to suit in wide Mach number flight. The system includes both closed and open operating modes. The heat sink and refrigerant are selected according to the mode to meet the energy requirements of the mission. By calculating the fuel penalty, it’s provided a basis for system selection under cooling capacity and power generation requirements, analyzing the adaptability of each subsystem. Closed systems have less fuel penalty at low Mach numbers compared with open system, but require larger cooling capacity from fuel.
