ABSTRACT:
A positive-displacement turbine engine comprising two rotors, exhaust opening for discharging exhaust gas, intake opening for receiving air and fuel or air-fuel mixture, turbine channels, turbine shaft, plurality of turbine blades, and spark plug. The rotors share a single shaft and are positioned in the opposite sides of the combustion head. Each of the turbine channels has a constant depth and varying width and comprises an intake zone, compression zone, combustion-expansion power-stroke zone, and exhaust zone. 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. The turbine blades maintain a constant lateral orientation while the two rotors rotate. Each turbine blade 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 rotors.
