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.
Claims20
An aircraft cooling assembly, comprising:
- a closed loop air cycle system that provides cooling to at least one first aircraft load, the closed loop air cycle system including a first compressor driven by an engine, and a turbine;
- a vapor cycle system that provides cooling to at least one second aircraft load, the vapor cycle system including a second compressor;
- a condenser;
- and an evaporator;
- and
- a coupling device that mechanically couples the turbine in the closed loop air cycle system to the second compressor in the vapor cycle system,
- wherein the turbine provides power to the second compressor via the coupling device using compressed air from the first compressor.

An aircraft cooling assembly, comprising:
- a closed loop air cycle system that provides cooling to air cooled aircraft loads, the closed loop air cycle system including a first compressor driven by an engine, a first turbine, and a second turbine;
- a vapor cycle system that provides cooling to liquid cooled aircraft loads, the vapor cycle system including a second compressor;
- a condenser;
- and an evaporator;
- a coupling device that mechanically couples the second turbine in the closed loop air cycle system to the second compressor in the vapor cycle system where the second turbine provides power via the coupling device to the second compressor through the expansion of air across the second turbine from the first compressor;
- and
- a heat expulsion system that provides a heat sink to the closed loop air cycle system and the vapor cycle system.
