Patent ID: 8015795

Claim:
An engine combination for generating forces, the engine combination 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, the gas turbine engine having a plurality of air transfer ducts each extending from a different location therein so as to be capable to provide air in each of those air transfer ducts at one end thereof at pressures differing from one another; and 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, the plurality of air transfer ducts each being connected at an opposite end thereof to the air intake to be capable of being selected to transfer air thereto.
