Abstract
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. A speed up gear train interconnects the motor shaft with an engine shaft which is journaled through the intermediate and turbine casings and extends through the combustion chamber member to the turbine casing outlet. A plurality of turbines secured to the engine shaft are rotatably mounted within the turbine casing outwardly of the combustion chamber and receive the high velocity exhaust gases from the combustion chamber and are rotatably driven thereby. Electronic ignition rods for the combustible mixture within the combustion chamber are connected to a suitable electrical power source. Interconnected gearing upon the engine shaft and the combustion chamber member provide continuous rotation of the combustion chamber.
