Abstract : This patent describes a structurally compact fuel-to-air heat exchanger, for a gas turbine engine, 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. The heat exchanger includes: a plurality of flow tubes through which cool combustor fuel flows, with the flow tubes in a crossflow relationship with and to the hot flow of cooling air; an air manifolding and flow-directing system; and, a fuel manifolding and flow-directing system. The heat exchanger is uniquely disposed internal of the gas turbine engine, within the fire safe cavity, which is ventilated.
