METHOD OF GENERATING PRESSURE PULSES IN ACOUSTIC CHAMBERS OF COMBUSTION CHAMBERS AND GAS GENERATORS OF LIQUID-PROPELLANT ROCKET ENGINES

摘要

FIELD: engines and pumps.;SUBSTANCE: in bursting thin metal 0.02-0.5 mm-dia wire and electric current propagation there through, heat power releases to bring about pressure pulse for it to propagate, as pressure wave, in combustion chamber acoustic cavity. Metal wire is exploded by discharging the capacitor there through, while pressure pulse magnitude and duration is adjusted by selecting capacitor capacitance and smooth variation of voltage across it.;EFFECT: high stability of pulse parametres, wide range of pulse parametres variation, simple procedure.;3 cl, 1 dwg
