An advanced Environmental Control System (ECS) for use in conjunction with a turbine engine to provide conditioned, pressurized air to an enclosed space such as an aircraft cabin, as well as cooling capacity for the aircraft avionics. The ECS features a dual turbine air cycle machine to minimize the amount of bleed air or power required from the turbine engine.

An environmental control system for conditioning air delivered to an enclosed space operated in conjunction with a multistage turbine engine providing power for the enclosed space, comprising: bleed air means for extracting an air flow of pressurized high temperature bleed air from the high pressure stage of said multistage turbine engine; first turbine means for directly receiving and converting latent thermal energy of said bleed air flow into rotational power; compressor means for receiving said bleed air flow from said first turbine means and for re-pressurizing said bleed air, said compressor means rotationally driven by said first turbine means; primary heat exchange means downstream of said compressor means for cooling said pressurized bleed air flow in heat exchange relationship with a flow of ram air; second turbine means for converting energy of said bleed air flow to rotational power and for further conditioning said bleed air flow, said second turbine means located downstream of said heat exchange means and integrally mounted to drive said compressor means; and duct means communicating with said second turbine means and said enclosed space for carrying said air flow to said enclosed space.
