FIELD: engines and pumps.
SUBSTANCE: proposed method comprises, in particular, cyclic ejection of combustion products and suction of atmospheric air. Circular vortex is generated at resonator tube inlet in combustion product cyclic ejection. This ups increase in rarefaction inside combustion chamber in blow cycle and, hence, intensifies filling said chamber with atmospheric air.
EFFECT: increased thrust of pulse duct.
