METHOD OF DETONATION COMBUSTION deflagration and detonation-deflagration PULSED ramjet ENGINE

摘要

1. A method for organization of the deflagration-detonation combustion in the jet engine for high speed flight, comprising the steps that the traveling speed supersonic air flow in a curved inlet inhibit space as it moves in the rate of formation of the zone of less than the velocity of the detonation wave occurring during combustion, the fuel is continuously supplied, it is mixed with air and create a continuous flow of a combustible mixture having an insufficient mixing zone "poor" in the input field of the mixture Fuel and well blended fuel mixture, in a zone located downstream, ignite well blended fuel mixture, formed with a detonation wave traveling faster than the flow velocity of the combustible mixture and the propagating together with the shock against the flow, quenched with immediate insufficient zone mixing due to self-quenching in the "lean" mixture, as arising from slaking foci of slow deflagration combustion carried away approach flow down the flow, fall into the well-mixed with the combustible admixture, ignite it, and initiate a new detonation wave propagating upstream realizing transition from deflagration to detonation, whereby organized process of detonation, deflagration combustion with high frequency ripple determined by high velocities of detonation waves and supersonic flow to the fuel nozzles and air inlet. 2. Management method deflagration-detonation combustion according to claim 1, characterized in that the fuel is supplied to zone the rate of formation of relatively large Mach number (M = 3-4) .3. Det
