Abstract

A lower pressure tap (46) is connected to a first heat exchanger (48) to be cooled by cooling air, and then to a selection valve (52). The selection valve (52) selectively delivers the lower pressure tap air to a boost compressor (44). The lower pressure tap air downstream of the boost compressor (44) is connected to cool the at least one turbine (32). The selection valve (52) also selectively delivers a portion of the lower pressure tap air across a first cooling turbine (78), and to a line (79) associated with an air delivery system for a cabin (80) on an associated aircraft. A portion of the air downstream of the first cooling turbine (78) is connected to a second cooling turbine (84), and air downstream of the second cooling turbine (84) is connected for use in a cold loop (88).
