ABSTRACT:
A structurally compact air-to-air heat exchanger, for a gas turbine engine of the fan bypass type, that permits a lower percentage of cooling air, than is presently needed in the art, to cool effectively the hot turbine, and its parts, of the engine. This goal is achieved, in part, by using a portion of the cool flow of fan air as a heat sink, without disturbing the flow of the fan air stream. The heat exchanger is disposed internal of the engine, and, it includes a plurality of flow tubes through which flows the hot cooling air, with the flow tubes positioned in a crossflow relationship with and to a portion of the cool flow of fan air. Three (3) variations of the preferred embodiment of the heat exchanger also are taught.
