Abstract: An aircraft cooling machine is provided that includes a closed loop air cycle system and a vapor cycle system that both provide cooling aircraft loads. The closed loop air cycle system includes a compressor and a turbine and the vapor cycle system includes a compressor, condenser and an evaporator. A coupler is provided that pneumatically couples the turbine in the closed loop air cycle system to the compressor in the vapor cycle system via existing pneumatic power in the closed loop air cycle system.

Abstract: A power and cooling management system configured to flexibly couple various adaptive modules to an integrated power and cooling unit to suit any aircraft platform is provided. The integrated power and cooling unit has a compressor(s), power turbine(s), cooling turbine(s) and integral starter generator(s) mounted to the shaft of the power and cooling turbine. The integrated power and cooling unit may be pneumatically and/or pneumatically coupled to an adaptive module that comprises an additional compressor and an additional turbine or electrically coupled to a fuel cell which provides the main power after entering the full operation mode. When the engine includes an integral starter generator mounted thereto, the integral starter generator of the integrated power and cooling unit is operative to receive electric power from the engine mounted generator. Alternatively, a motor/generator may be mounted to the shaft of the additional turbine of the adaptive module.
