Patent ID: 8079343

Claim:
A positive-displacement turbine engine comprising: two rotors; an exhaust opening for discharging exhaust gas; an intake opening for receiving air and fuel or air-fuel mixture; turbine channels; a turbine shaft; a plurality of turbine blades; and a spark plug; wherein two rotors share a single shaft and face a single central combustion head with opposite sides, wherein the turbine channels are positioned on the opposite sides of the combustion head; wherein each of the turbine channels has a constant depth and a varying width; wherein said each of the turbine channels comprises an intake zone, a compression zone, a combustion-expansion power stroke zone, and an exhaust zone; and wherein said each of the turbine channels widens in the intake zone, narrows in the compression zone, widens in the combustion-expansion power-stroke zone, and narrows in the exhaust zone; wherein the plurality of turbine blades maintain a constant lateral orientation while the two rotors rotate; and wherein each turbine blade of the plurality of turbine blades has a blade-rod with two ends and a downward-offset crank on one end of the blade-rod that maintains the turbine blade in a constant horizontal orientation during rotation of the two rotors.
