Abstract
Hot compressed air is bled from the compressor of an engine and a portion of it is directed through a flow through type indirect heat exchanger of ring form located within an annular chamber in the engine cowl which is partially formed by lip surfaces of the inlet. Such air gives up heat to low pressure air within such chamber which carries the heat to the inlet surfaces. The compressed air is then removed from the heat exchanger and is admixed with additional hot compressed air. A part of the mixture is delivered to a wing TAI subsystem and a second portion is used for cabin conditioning and pressurization.
