Abstract

A rotary pulse detonation engine produces mechanical output by detonating a fuel/air mixture in detonation chambers between adjacent impeller blades. The impeller is housed within an outer casing and rotated around an inner sleeve. Air is passed through a velocity stack and through intake ports on the inner sleeve into the detonation chambers. Fuel is injected into the detonation chamber through fuel line(s). Igniters on the interior of the outer casing ignite the fuel and produce the detonations. Spent gas is released through exhaust ports situated on the outer casing, front plate or rear plate. The impeller may be supported by front and rear bearings in low speed applications, or by a pressurized cushion of air provided by exhaust gases directed to the front and rear ends of the impeller by a perforated tube sheet positioned between the impeller and the inner sleeve in high speed applications.
