INTEGRATED ENVIRONMENTAL CONTROL AND BUFFER AIR SYSTEM

An environmental control system (62) for an aircraft includes a higher pressure tap (72) to be associated with a higher compression location and a lower pressure tap (74) to be associated with a lower pressure location in the main compressor section associated with the aircraft engine. The lower pre...

Beschreibung
Zusammenfassung:	An environmental control system (62) for an aircraft includes a higher pressure tap (72) to be associated with a higher compression location and a lower pressure tap (74) to be associated with a lower pressure location in the main compressor section associated with the aircraft engine. The lower pressure tap (74) communicates to a first passage leading to a downstream outlet, and has a second passage leading into a compressor section (80) of a turbocompressor (78). The higher pressure tap (72) leads into a turbine section (82) of the turbocompressor (78) such that air in the higher pressure tap (72) drives the turbine section (82) to in turn drive the compressor section (80) of the turbocompressor (78). A turbine outlet (86) receives airflow exhausted from the turbine section (82). A compressor outlet (84) receives airflow exhausted from the compressor section (80). A combined outlet (90) receives airflow from the turbine outlet (86) and the compressor outlet (84) intermixing airflow and passing the mixed airflow downstream to be delivered to an aircraft. A buffer air outlet (112) communicates airflow to an engine buffer air system (66) and receives airflow supplied to the turbocompressor (78).
