Patent ID: 7784267

Claim:
A detonation engine comprising: a plurality of guide vanes which generate a circumferential rotational flow in a mixed gas of air and fuel or a mixed gas of oxygen and fuel about a centerline axis; at least one fuel injector arranged upstream of said guide vanes, with respect to the flow of the mixed gas; a detonation chamber which is arranged on a downstream and radially outward side of said guide vanes, formed in a ring-shape that is radially extended and continuous in a circumferential direction, in which detonation waves and a combustion gas at a high temperature and under a high pressure that continuously flow in an outward radial direction, with respect to the centerline axis through the detonation chamber, are generated by combusting the mixed gas in which the circumferential rotational flow is generated by said plurality of guide vanes; and a nozzle connected to said detonation chamber that discharges the detonation waves to the rear, expands the combustion gas, and converts the combustion gas into thrust, the combustion gas flowing continuously to the rear while rotating.
