Patent ID: 8205433

Claim:
An apparatus, comprising: a main pulse detonation chamber comprising a proximal end portion, a distal end portion having an exhaust aperture, and a main body extending therebetween, the exhaust aperture having a diameter substantially smaller than a diameter of the main body; and a plurality of separate internal pulse detonation chambers positioned within the main body of the main pulse detonation chamber, each internal pulse detonation chamber comprising a proximal end portion, a distal end portion having an exhaust aperture, and a main body extending therebetween, the main body including a fuel inlet port, wherein the main pulse detonation chamber is configured so that initial combustion takes place separately inside each of the plurality of internal pulse detonation chambers; and wherein the plurality of separate internal pulse detonation chambers are positioned so that exhaust fluid from each of the plurality of internal pulse detonation chambers is commonly released into the main pulse detonation chamber at a location substantially upstream of the exhaust aperture.
