In an engine of the type wherein the combustion of fuel is initiated by a detonation wave, a plurality of axisymmetrical rotor elements are fixed along the length of a drive shaft. The drive shaft has a central longitudinal chamber which is supplied with the fuel mixture. Each rotor element has an annular initiation chamber which communicates with the central chamber of the shaft and a system of ducts which extend outward from the initiation chamber to exhaust openings. The initiation chambers and the associated systems of ducts are selectively filled with the fuel mixture and detonation is selectively initiated in the initiation chambers. This detonation produces detonation waves which propagate outward in the ducts resulting in the combustion products being ejected from the ducts in the form of high speed jets to produce rotational moment on the rotor/shaft unit. The speed of the exhaust jets may be modified to tailor the jet speed to the speed of rotation by varying the divergence of nozzles at the ends of the ducts or by injecting a secondary fluid into the exhaust jet.
