Patent ID: 7841167

Claim:
An engine comprising: at least one pulse detonation combustor having an exit nozzle in which a combustion exhaust passes therethrough; a bypass duct which surrounds at least a portion of said pulse detonation combustor such that an outer surface of said pulse detonation combustor forms an inner surface of said bypass duct, said bypass duct having an exit portion in which a bypass air flow passes therethrough, the exit portion of said bypass duct and the exit nozzle of said at least one pulse detonation combustor proximate each other to cause mixing of the bypass air flow and the combustion exhaust; and a bypass control valve in fluid communication with the bypass duct, the bypass control valve allowing air flow to enter into the bypass duct when the bypass control valve is in an open position, and preventing air flow from entering into the bypass duct when the bypass control valve is in a closed position.
