FIELD: manufacture of engines; rotary engine at irregular motion of blades.

SUBSTANCE: proposed engine has two rotors; blades of inner rotor are directed outside and blades of outer rotor are directed inside. Each rotor has two roller couplings: one coupling with outer holder on output shaft and other coupling with outer holder on fixed body; they are mounted for rotation of both rotors in one direction. Engine is provided with intake spool valves on inner and outer rotors and exhaust spool valves fitted with waste gas discharge passages located on opposite sides of inner rotor blades.
