A continuous cycle dual rotor propulsion system wherein Freon R12 with synthetic motor oil added to it circulates through a closed circuit conduit in which a pump-compressor 32, heat generator 36, propulsion unit 12 and condenser 30 are connected in series. The fluid is super-heated in the heat generator and the gas so generated is directed through a narrow, generally rectangular flow duct through the propulsion unit where it impinges upon the blades of a pair of rotors 14, 16 rotatably mounted therein. The flow duct is tangential to each of the rotors and the rotor blades conform in outline to the cross-sectional shape of the flow duct. The rotors are geared to a common drive output which, inter alia, drives the pump-compressor. <IMAGE>
