METHOD OF BURNING FUEL-deflagration and detonation PULSED ramjet ENGINE

摘要

1. A method for the organization of fuel combustion to produce reactive thrust ramjet engine for high flight speeds, consists in the fact that the incoming high-speed supersonic air stream as it moves into its air intake to inhibit a relatively large Mach number (M = 3-4), it was continuously fed fuel, the resulting combustion mixture is directed to "lattice channels", where cross-section of each channel is less than the transverse dimension of detonation cells formed during combustion, detonation wave traveling faster than the flow rate of the combustible mixture and propagated upstream, quenched by entering the channels arising from this shock wave and edges slow ( deflagration) burning, brings forth coming with greater speed than the speed of shock waves, the fuel mixture, allowing the transition of burning deflagration to detonation, resulting in organized continuing unsteady combustion in a dynamically pulsating (emerging and fading) of detonation waves and fronts slow goreniya.2. Detonation, deflagration pulsating ramjet engine and serving to implement the method of claim. 1, characterized in that it comprises successively arranged in the flow path of the engine supersonic air intake, a continuous fuel feed system, a lattice plate absorber detonation waves which is located behind the inlet zone sufficiently well-mixed fuel-air mixture, the combustion chamber and the exhaust nozzle, the supersonic air intake is designed so that its outline t
