Abstract
A pulse detonation engine is provided with at least one detonation combustor selectively coupled to an air inlet and fuel source. The detonation combustors are equipped with either active or passive means to dissipate the heat of detonation. Fuel, air, and an oxidizer can be fed to said detonation combustors either through a rotary valve or through a conically shaped injector head.
Claims39
A rotary valve multiple combustor pulse detonation engine, comprising;
- at least two detonation chambers, each having an inlet end and an outlet end and further including means for preventing heat degradation of said chambers;
- a fuel manifold for supplying fuel from a fuel source to said at least two detonation chambers at said inlet ends;
- an inlet air duct manifold for supplying air to said at least two detonation chambers at said inlet ends;
- a means for initiating a pulsed supersonic shock wave-triggered detonation combustion wave in said at least two detonation chambers;
- and
- a rotor disk valve having at least one opening and at least one solid portion, wherein said rotor disk valve is positioned between said inlet ends of said at least two detonation chambers and said fuel and inlet air duct manifolds, wherein said rotor disk valve rotates so that said opening is positioned over said inlet end of one of said at least two detonation chambers to allow fuel and air to enter said one of said at least two detonation chambers, and wherein said rotor disk valve further rotates so that said solid portion is positioned over said inlet end of said one of said at least two detonation chambers so that said fuel and air inside said one of said at least two detonation chambers can be detonated by said means for initiating a pulsed supersonic shock wave-triggered detonation combustion wave.

A pulse detonation engine comprising:
- at least one detonation chamber having an inlet end and an outlet end, and further comprising means for preventing fuel oxidizer autoignition and heat degradation of said chamber, said inlet end comprising an injector head having a plurality of openings therein, said openings adapted to act as:
- an inlet fuel manifold for supplying fuel from a fuel source directly to said at least one detonation chamber;
- and
- an oxidizer manifold for supplying an oxidizer to said at least one detonation chamber;
- a fuel source;
- an inlet air duct manifold for supplying air directly to said at least one detonation chamber;
- and
- a means for initiating a pulsed supersonic shock wave-triggered detonation combustion wave in said at least one detonation chamber.
