Patent ID: 6920761

Claim:
A hybrid power plant apparatus wherein certain physical aspects of an internal combustion engine and a high pressure turbine jet engine are combined, comprised of: a tuned port combustion chamber formed by a hemispherical section at the inlet end with a single inlet valve centered at the cap of said hemispherical section, a cylindrical center section containing one or more fuel injector and sparking device pairs disposed longitudinally, radially or a combination of both within said cylindrical center section, and a conical outlet section with a tunable variable geometry output port, said tunable variable geometry output port coupled to a turbine such that a constant volume of modulated low pressure air impulsed at said single inlet valve and fuel injected into said tuned port combustion chamber by said one or more fuel injectors are ignited by said one or more sparking devices creating a pulse of energy which is impinged on said turbine, said low pressure and said fuel being repetitively introduced into said tuned port combustion chamber to create a continuous series of energy pulses, said continuous series of energy pulses occurring at or near a resonant frequency determined by the physical construction of said tuned port combustion chamber.
