Patent ID: 6907723

Claim:
A pulsed turbine rotary engine comprising: a fixed section defining an exhaust chamber and a plurality of intake openings each defining an intake axis; an output shaft supported by the fixed section for rotation about a shaft axis; a plurality of nozzle housings operatively connected to the output shaft for rotation about the shaft axis through a combustion cycle, where each nozzle housing defines a nozzle chamber in fluid communication with a nozzle inlet and a nozzle outlet, and each nozzle outlet defines a thrust axis, the nozzle outlets are in continuous fluid communication with the exhaust chamber during the combustion cycle; an air supply system supported by the fixed section for directing air through the intake openings; a fuel supply system supported by the fixed section for directing fuel through the intake openings; and an ignition system comprising spark plugs supported by the nozzle housings for igniting fuel within the nozzle chambers; wherein the nozzle inlets substantially align with each intake opening once during each rotation of the nozzle housings; the intake system and fuel system direct air and fuel into the nozzle chambers through the aligned intake openings and nozzle inlets; the ignition system ignites the fuel and air within the nozzle chambers to create expanding exhaust gasses that exit the nozzle chambers through the nozzle outlets; and the nozzle thrust axes are configured such that the nozzle housings and output shaft rotate about the shaft axis relative to the fixed section in reaction to movement of the expanding exhaust gasses through the nozzle outlets.
