  • Pilot fuel injection for a wave rotor engine
    Patent number: 8443583
    Abstract: Apparatus and methods for combustion of fuel. Some embodiments of the inventions include a fuel nozzle which injects fuel into a combustion channel of a wave rotor combustor or a pulse detonation combustor In some embodiments the combustion process includes a backward-propagating detonation wave within a substantially closed channel which compresses discrete quantities of combustible and noncombustible mixture. Yet other embodiments include a precombustion chamber integrated into the wave rotor, the outlet stator or both.

  • Wave rotor apparatus
    Patent number: 7555891
    Abstract: A wave rotor apparatus is provided. In another aspect of the present invention, a radial wave rotor includes fluid passageways oriented in a direction offset from its rotational axis. A further aspect of the present invention employs stacked layers of generally radial channels in a wave rotor. Moreover, turbomachinery is located internal to a wave rotor in yet another aspect of the present invention. In yet another aspect of the present invention, a radial wave rotor has an igniter and fuel injector. Correctional passages are employed in still another aspect of the present invention wave rotor.
