ABSTRACT:
An environmental control system for a jet aircraft has a single compressor coupled to a cooling turbine and an auxiliary power turbine. The compressor provides air to both turbines. Air to the power turbine is mixed with fuel to form combustion gases to drive the turbine. Air to the cooling turbine is cooled by expansion and used for air conditioning the aircraft cabin. The auxiliary power turbine can be decoupled and the compressor driven by the cooling turbine, which is powered by bleed air from the main engine of the aircraft.
