A high performance turbine engine includes refrigeration apparatus powered by the engine and effective upon a fractional air flow received from the engine compressor to provide chilled air for cooling of internal engine components. The refrigeration process facilitates rejection of unwanted heat to ambient air despite high stagnation temperatures at high flight speeds. The invention allows increased turbine inlet temperature and improved fuel efficiency or thrust per pound of engine weight with present-day metals and cooling technology being used for engine construction.

A turbine engine comprising a compressor inducting ambient air and delivering this air pressurized to a combustor, means for introducing fuel to said combustor to sustain combustion producing a flow of high-temperature pressurized combustion products, a turbine receiving said high-temperature pressurized combustion products for expanding the latter toward ambient and drivingly connecting with said compressor, and refrigeration means for receiving both a fractional flow of said pressurized air and power input from said engine driving a refrigeration cycle cooling said fractional air flow, and means for applying said cooled fractional air flow to a rotating turbine blade of said turbine.
