Patent ID: 7591129

Claim:
A rotary orbiting piston pulse detonation engine including: a housing defining a pre-combustion chamber, a detonation chamber in fluid communication with said pre-combustion chamber; a first outlet from said detonation chamber, a circular toroidal chamber in fluid communication with said first outlet said first outlet having an axis extending substantially tangential to an internal surface of said toroidal chamber; and a second outlet providing fluid communication from said toroidal chamber with the atmosphere; a shaft mounted for rotation in said housing; a rotor located in said housing extending from the toroidal chamber to said shaft and drivingly connected to said shaft; a toroidal segment piston located in the toroidal chamber and drivingly connected to said rotor; a fuel injector in said pre-combustion chamber; an igniter in said detonation chamber; a one-way flow control valve located between said pre-combustion chamber and said detonation chamber allowing fluid flow from said pre-combustion chamber to said detonation chamber; and controls for supplying an explosive fuel air mixture to said injector and pre-combustion chamber and electrical energy to said igniter for igniting the explosive fuel air mixture in said detonation chamber creating a shock wave impacting said piston.
