Abstract:
Apparatus and method for conditioning engine-heated air onboard an aircraft including a heat exchanger (140) at least partially disposed in a pylon structure (118) for supporting an engine (134) of the aircraft. The pylon heat exchanger (140) extracts heat from a flow (156) of engine-heated air. A flow (142) of ambient air is provided to the pylon heat exchanger (140) from a ram air inlet (150).
