Eidelman, S

In an engine of the type wherein the combustion of the fuel mixture is carried out by a detonation wave, the improvement is described comprising: (a) an elongated shaft having a central longitudinal chamber, the chamber being supplied with a detonatable fuel mixture; (b) axisymmetrical elements integral with the shaft and disposed along the length thereof; (c) means for selectively introducing the detonatable mixture from the central chamber into the initiation chamber of each axisymmetrical element and the ducts of the axisymmetrical element; and (d) means for selectively initiating detonation of the fuel mixture in the initiation chamber of each the axisymmetrical element, whereby ignition and detonation of fuel mixture in the initiation chamber will produce a detonation wave which travels outward from such initiation chamber in the ducts to initiate fast combustion of the fuel mixture in the ducts. The combustion products are exhausted from the exhaust openings in the form of high speed jets oriented to produce a rotational moment in the element and the shaft.
