ABSTRACT:
A three-stage internal combustion rotary engine, comprised of: a compressor feeding compressed air to a combustor for compression, fuel injection, combustion, and expansion of gases which rotate the rotor. The combustor rotor generates torque and drives the compressor and afterburner rotors simultaneously. The afterburner receives the combusted gases and scavenged air from the combustor for secondary combustion and expels the exhaust gases. Each unit consists of a housing joined together on a common axis and a rotor with a shaft mounted in an eccentric position of the housing side-walls. The shafts are interconnected by splines. The rotors have radial blind slots which contain slidable, movable vanes fitted with half-round knobs on opposite sides, aligned with the top surface and fit in the hemispherical grooves on the interior side-walls of the housing. This maintains a permanent contact with the interior housing periphery, regardless of gas pressures and rotating speed.
