CONCEPT STUDY ON ENVIRONMENTAL CONTROL SYSTEMS WITH LESS FUEL PENALTIES

Future high performance military fighter aircraft will demand an Environmental Control System (ECS) with more cooling capacity, lower weight, and lower fuel consumption. Subsystems integration technologies could provide benefits such as these for future military aircraft. This paper introduces a new integration concept which integrates all aircraft and energy power and cooling systems into a Thermal and Energy Management Module (T/EMM). The T/EMM is the heart of the concept and consists of heat exchangers, compressor, cooling turbine and power turbine with a generator, hydraulic pump, combustor and controls. It could provide the cooling function and power traditionally performed separately by an ECS and other subsystems. A mathematical model for this system in cruise mode is established. The computes are completed under the same flight conditions as advanced F 15. And the effects of parameters of several accessories are investigated. The calculated results show that the integrated ECS has more Coefficient of Performance ( COP ) and less related fuel penalties than the advanced F 15 ECS.
