RU198929U1 - SHOT SILENCER - Google Patents

Abstract

The proposed utility model relates to the field of small arms, namely to devices for jamming the sound of a shot. The task is achieved by the fact that the muffler body has channels for exhausting gases towards the muzzle of the muffler body, the number of which increases to the muzzle of the muffler body. The technical result is reducing the gradient of the shot sound.

Description

The proposed utility model relates to the field of small arms, namely to devices for jamming the sound of a shot. Known is a device for muffling the sound when fired (Patent RU2 414 668), containing a muffler housing having stepped outlet openings. However, the specified device does not allow to reduce the gradient of the volume of the sound of the shot when the propellant gases exit from the muffler housing.

In addition, a weapon muffler is known (Patent RU 2 231 011), which is a prototype of the proposed utility model, containing a muffler housing with holes for gas outlet. However, in the specified device, the direction of the gases outlet is not used to reduce the gradient of the loudness of the shot sound, since the shape of the bell implies the removal of powder gases on the sides of the muzzle of the muffler body.

The task (technical result) of the proposed utility model is to reduce the gradient of the loudness of the sound of a shot.

The task is achieved by the fact that the muffler body has channels for exhausting gases towards the muzzle of the muffler body, the number of which increases towards the muzzle of the muffler body.

The proposed device silencer for the sound of a shot (Fig. 1) contains:

1- Muffler housing, 2- Propellant gases outlet

The device works as follows:

As you know, powder gases breaking through the gap between the bullet and the bore walls create a sound volume level that reaches 100-125 dB. Gases with a high noise gradient are emitted, i.e. the sound of a shot has a distinct sharp sound against the background of other noises. 2

It is possible to reduce the sharpness by reducing the sound gradient by gradually withdrawing more and more gases towards the muzzle of the muffler body.

Action scheme:

The bullet starts moving along the muffler body. The channels are located in such a way that as the bullet progresses, the channels gradually release a larger amount of powder gases towards the muzzle of the muffler body. Thus, the smoothness of the emission of gases is achieved, which helps to mask the sound of a shot against the background of other sounds. The gradual release of gases will allow to "accelerate" the medium in front of the barrel for a more smooth bullet exit. The sound becomes less distinct and the arrow can be seen at a greater distance from the enemy's acoustic reconnaissance systems. The number of channels increases towards the muzzle of the muffler body to achieve the required smoothness of the powder gases outlet.

Channels can be implemented in any form that is most convenient for production. The number of channels depends on the required degree of sound gradient reduction. The more gradually it is necessary to release the powder gases, the greater the number of channels. The channels for the outlet of the powder gases are not connected in order to avoid braking the projectile by the powder gases flowing in the opposite direction. The technical result is to reduce the gradient of the shot sound.

Claims (1)

The muffler of the sound of a shot, containing the muffler body, characterized in that there are channels inside for the outlet of powder gases from the muzzle of the muffler body, the number of which increases towards the muzzle of the muffler body.
