ABSTRACT:
A turbo fan gas turbine engine is disclosed which includes a central engine and a shroud-enclosed fan, the shroud being supported by a plurality of structural struts extending from the central engine to the shroud. A plurality of tubes internal to each strut are provided with fins to increase their effective internal surface areas. Means are provided for connecting the tubes to a source of heated hydrocarbon liquid and for providing a return from the tubes to the source of hydrocarbon liquid, whereby the tubes provide cooling for the liquid. In a preferred embodiment of the invention, the tubes are surrounded by a highly conductive cement to provide support and improved heat transfer between the tubes and the struts.
