  • Patent number: 4724670
    Abstract: A turbine engine includes an elongated motor having a power source and a drive shaft. A first compressor connected to a fuel inlet, and a second compressor having an air inlet are coaxially mounted for rotation upon the motor. An elongated casing for the second compressor terminates in an intermediate casing which defines a pair of diffuser chambers, and terminates in a turbine casing having a converging exhaust outlet. Pressurized high velocity vaporized fuel and compressed air are delivered into the diffuser chambers and through a plurality of fuel injectors to continuously feed air and combustible fuel into an elongated combustion chamber member which is rotatably mounted within the turbine casing. One end of the combustion chamber member extends into and is journaled upon the intermediate casing.
