Abstract
An environmental control system for an aircraft is provided. The environmental control system comprises a bleed air system. Also included is a ram air system. Further included is an air pressure and temperature conditioning system, wherein bleed air and ram air are mixed to satisfy a cabin fresh air requirement. The air pressure and temperature conditioning system includes a compressor that pressurizes ram air. The air pressure and temperature conditioning system also includes a power turbine that expands bleed air, the pressurized ram air and expanded bleed air at identical pressures prior to mixing downstream of the compressor and the power turbine.
