Patent ID: 7533530

Claim:
An engine comprising: a detonation chamber, said chamber comprising a wall, a chamber sensor and a gauge, said chamber sensor measuring a chamber pressure within the chamber, said gauge measuring a temperature at the wall; a tank, said tank in contact with the wall and comprising a tank sensor, a tank inlet, and a tank outlet, said tank sensor measuring a tank pressure within the tank, said tank inlet comprising a tank inlet valve, said tank outlet comprising a tank outlet valve; a fuel system interconnected to the chamber comprising an oxidizer source, at least one fuel injector interconnected to at least one fuel reservoir, and an exhaust, said oxidizer source comprising an oxidizer valve, said fuel injector comprising a fuel valve, said exhaust comprising an exhaust valve; and a controller, said controller: (a) determining a rate and an amount of at least one oxidizer and a rate and an amount of at least one fuel, said rates derived from at least one of the temperature, chamber pressure, a requested amount of an energized fluid, and at least one property of the fuel and the oxidizer; (b) determining a detonation rate derived from at least one of the temperature, chamber pressure, requested amount of energized fluid, the property of the fuel, and the property of the oxidizer; (c) controlling the injection into the chamber from the fuel system of the determined amount of oxidizer at the determined oxidizer rate and the determined amount of fuel at the determined fuel rate; (d) controlling the detonation of a mixture of the oxidizer and fuel in the chamber at the detonation rate, wherein the detonation produces an energy and at least one detonation product; (e) controlling the injection of a fluid into the tank, wherein the energy transfers through the wall to the fluid converting the fluid into energized fluid, said injection determined from the detonation rate; (f) determining the amount of tank pressure in the tank and controlling the release of the energized fluid from the tank; said release determined from the tank pressure and the requested amount of energized fluid; and (g) controlling the release of a portion of the detonation product from the chamber.
