Claims (1)

Огнестрельное малошумное оружие, содержащее ствол с выполненными на внутренней поверхности канала ствола винтовыми нарезными пазами, служащими для придания пули вращения вокруг ее продольной оси с целью обеспечения устойчивого полета, отличающееся тем, что на внутренней поверхности по длине дульной части ствола винтовые пазы, совпадающие с направлением вращения винтовых нарезов, выполнены с постепенным увеличением поперечных сечений в сторону выхлопа пороховых газов за счет глубины пазов, при перемещении пули в дульной части ствола через зазоры между телом пули и дном пазов, пороховые газы прорываются во внутреннею полость ствола впереди пули, за счет дросселирования и расширения пороховых газов в пазах и во внутренней полости ствола происходит динамическое падение давления пороховых газов позади пули до ее выхода из ствола и в результате понижается звук выстрела.Low-noise firearms containing a barrel with screw threaded grooves made on the inner surface of the barrel channel to give the bullet rotation around its longitudinal axis in order to ensure a stable flight, characterized in that on the inner surface along the length of the muzzle of the barrel there are screw grooves that coincide with the direction the rotation of the screw rifling, made with a gradual increase in cross sections towards the exhaust of the powder gases due to the depth of the grooves, when moving the bullet in the muzzle of the barrel Through gaps between the body of the bullet and the bottom of the grooves, the powder gases break into the internal cavity of the barrel in front of the bullet, due to the throttling and expansion of the powder gases in the grooves and in the internal cavity of the barrel, the pressure of the powder gases behind the bullet dynamically drops out of the barrel and as a result decreases the sound of a shot.
