Initiation of combustion of supersonic propane-air flow by magnetoplasma compressor discharge

Results are given of investigations of the initiation of ignition and combustion of an air-propane flow in a supersonic wind channel with preheating by a pulsed discharge of a low-power magnetoplasma compressor of the erosion type. The mode of explosive ignition of mixture with formation of a combustion wave propagating towards the flow is revealed. The effect of initial conditions (fuel excess coefficient, preheating of air) on the spatial position and intensity of ignition is investigated.
