Patent attributes
Increased efficiency and reliability is achieved in an engine with a combustion chamber structured as detonation resonator with an outlet to an exhaust nozzle. The resonator is formed as an aspherical reflector symmetrical with respect to the engine axis. The engine uses gaseous fuels and a gaseous oxidizer in a single stage combustion process. A pyrolyzing chamber for hydrocarbon fuel. Pyrolizing is achieved by contact of fuel flow with heated back side of the reflector. A mixture of fuel and oxidizer is supplied into the combustion chamber through an annular supersonic injection system. To initiate detonation, these engines may have a detonation initiator formed as a tube plugged at the distal end and open at the end inserted into the combustion chamber and located along the axis of the engine. Detonation products ejected through the exhaust nozzle create thrust that pushes the engine in the opposite direction.
