The bleed air requirements for a pressurization and environmental control system for the cabin (10) of an aircraft may be reduced by a system that includes a turbomachine (20) having a rotary compressor (22) driven by a turbine wheel (26). A ram air inlet (16) is connected to the compressor inlet (28) and the aircraft is provided with a cabin air exhaust port (18) which is connected to the outlet (34) of the turbine wheel (26). A heat exchanger (40) has a cabin inlet air flow path (42) and a cabin outlet air flow path (44) in heat exchange with one anoth...
[ What is claimed is:] [1.] An aircraft comprising:a sealable aircraft cabin;means for maintaining a desired pressure within said cabin, including means for providing fresh air to said cabin and means for dumping air from said cabin overboard;a rotatable turbine wheel associated with said dumping means such that air being dumped overboard is expanded to rotate said turbine wheels;a compressor having an outlet and connected to said turbine wheel for harnessing the rotation thereof;means for using air expanded from said turbine wheel for cooling purposes;a...
