1. A rotary valve multiple combustor pulse detonation engine comprising:

  • at least two detonation chambers, each having an inlet end and an outlet end;

    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;

    means for initiating a pulsed supersonic shock wave-triggered detonation combustion wave for initiating detonation 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 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 detonation chamber, 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.
