Abstract
An air cycle machine for use within an Environmental Control System (ECS) operating in conjunction with a turbine engine. The air cycle machine includes two turbines commonly mounted on a shaft with a compressor. The air cycle machine is designed to directly receive high temperature, high pressure bleed air from the turbine engine and maximize energy extraction and utilization of the bleed air.
Claims24
An air cycle machine for use within an environmental control system, comprising:
- first turbine means for extracting useful work from a flow of high temperature gas;
- compressor means for receiving said flow of gas from said first turbine means and re-pressurizing said flow of gas to a higher pressure;
- second turbine means for receiving said flow of pressurized gas conducted within said environmental control system from said compressor means to said second turbine means, and for extracting useful work therefrom;
- shaft means for interconnecting said first turbine means, said compressor means, and said second turbine means, said compressor means thereby directly driven by both of said first and second turbine means;
- and
- housing means for enclosing and supporting said first and second turbine means, said compressor means, and said shaft means.
