A turbine engine (20) having bypass and core passages (30 and 40), a high pressure compressor (80) for compressing air in the core passage and an intercooler (120, 220) for cooling core air (42) in the core passage prior to discharge by the high pressure compressor. The intercooler includes a plurality of heat exchange elements (140) positioned in the bypass passage through which all or a portion of the core air is transported. Heat in the core air is transferred via the heat exchange elements to the relatively cool bypass air, thereby cooling the core air and heating the bypass air. The turbine engine may have a counterflow intercooler (120), a radial flow intercooler 220 or an intercooler of other configuration. The turbine engine may have a high pressure compressor with two sections (82 and 86), with core air transported to and from the intercooler between sections, or a single section high pressure compressor, with core air transported to and from the intercooler upstream of the high pressure compressor. The turbine engine may be of turbofan, turboshaft, turboprop or other design.

[ What is claimed is:] [1.] A turbine engine that produces thrust, comprising:a. a low pressure compressor:b. a core air passage through which core air flows;c. a high pressure compressor connected to said core air passage, said high pressure compressor having an outlet;d. a bypass air passage through which bypass air flows, said bypass air having less thermal energy than said core air;e. an intercooler connected to said core air passage and extending into said bypass air passage, wherein said intercooler is constructed to transport more than a mass bleed flow amount of said core air comprising at least twelve percent, by mass, of said core air from said core air passage through said bypass air passage, where thermal energy from said core air is extracted, and back to said core air passage, upstream of said outlet, in a single thermodynamic cycle; andf. wherein said bypass air passage is constructed such that said extracted thermal energy contributes to the thrust of the turbine engine.
