Patent ID: 7836680

Claim:
An engine combination for generating forces, the engine system comprising: a gas turbine engine having an air inlet open to the atmosphere, an air compressor, a combustor, a turbine and an exhaust exit nozzle open to the atmosphere all positioned along a fluids flow path passing therethrough for generating force, and utilizing an engine lubricant for lubricating moving components in the gas turbine engine, the air compressor having an air transfer duct extending therefrom so as to be capable to provide compressed air in that air transfer duct at one end thereof; an internal combustion engine provided as an intermittent combustion engine having an air intake coupled to combustion chambers therein and a rotatable output shaft also coupled to those combustion chambers for generating force, and utilizing a coolant for transporting heat generated in the intermittent combustion engine away therefrom, the air transfer duct being connected to the air intake at an opposite end to be capable of transferring compressed air thereto; a coupling heat exchanger coupled to both the gas turbine engine and the intermittent combustion engine as a first coupling subsystem to have the engine lubricant and the coolant pass therethrough to permit the coolant to transport heat in the engine lubricant away therefrom; and a cooling heat exchanger coupled to both the coupling heat exchanger and the intermittent combustion engine as a second coupling subsystem to have a remote fluid from a source thereof and the coolant pass therethrough to permit the remote fluid to transport heat in the coolant away therefrom, and with the coolant also circulating through at least one of the coupling heat exchanger and the intermittent combustion engine.
