Research on Modeling and Simulation of Environmental Control System for Multipurpose Thermal Utilization of Fighter Aircraft

Aiming at the waste of airborne heat due to the relative independent design of the air conditioning subsystem and the equipment cooling subsystem in the traditional environmental control system, this paper proposes a way of crosslinking the air conditioning subsystem and the equipment cooling subsystem from the point of view of heat management and utilization. Based on AMESim software platform, the proposed system architecture is simulated and compared with the traditional independent subsystem design. It is concluded that thermal comprehensive utilization loop control system can effectively reduce the flow requirements of the engine bleed under the air conditioning heating mode, as well as share the heat pressure of the fuel system and reduce the heat compensation loss of the system.
