RU75730U1 - CARTRIDGE FOR SMOOTHING GUNS - Google Patents

Abstract

The utility model relates to the field of designing cartridges for smooth-bore weapons, namely to the design of shotgun cartridges. The technical result of the claimed utility model is to increase the flight speed of a shot projectile while maintaining the advantages of the above counterparts. The claimed technical result is achieved due to the fact that the cartridge for smoothbore guns containing a sleeve, wad, shotgun, powder charge, primer, characterized in that the powder charge is divided into two chambers with a diaphragm with a hole.

Description

Application area

The utility model relates to the field of designing cartridges for smooth-bore weapons, namely to the design of shotgun cartridges.

State of the art

From the prior art, the closest analogue is patent RU 2229092 for a wad-container for shotgun shells contains a beaker for shots, the side wall of which consists of four petals separated by cuts, connected by jumpers, a shock absorber and a seal. The width of the slots is 1.0 ± 0.2 mm, and the length is 0.75-1.0 of the height of the cup, jumpers, the number of which is from 2 to 4 for each slot, are evenly spaced no more than 7 mm from the open end of the cup and have a thickness of at least 0.3 mm and a width of 1 ± 0.15 mm, and a protrusion in the form of a thick-walled ring with an outer diameter of at least 0.7 of the outer diameter of the wad of the container and a height of at least 3.0 mm is made on the inner surface of the shutter. The use of the invention increases the accuracy of fire and simplifies the manufacturability of the wad-container. The disadvantage of this solution is the limited speed of the shotgun projectile by the size of the powder charge chamber.

Also the closest analogue is the patent RU 2197703 for PAPER COMBINED CASE FOR CARTRIDGES FOR SMOOTHED GUNS. The sleeve consists of a paper tube rolled from several layers of paper and pinched between the bottom wad and a metal base, while the tube is rolled from paper 100-160 μm thick and having a temporary resistance (kgf / cm2) of at least 9 in the machine direction, 5 in the transverse direction direction and elongation (%) of at least 3 in the machine direction, 7 in the transverse direction, and the height of the bottom wad is equal to the height of the metal base with an accuracy of 0.5 mm or less than the height of the metal base, and the wall thickness of the metal base hcr is less than the critical value of hcr chosen by the empirical formula hcr = (2H) / t, where t is the resistance

the yield strength of the base metal, is the temporary resistance of the paper in the transverse direction, N is the wall thickness of the paper tube. As paper, insulating cardboard according to GOST 2824-86 can be used. The developed sleeve is environmentally friendly, has a dynamic strength 2 times higher than the currently existing paper sleeve, and ensures the reliable functioning of hunting cartridges in various shotguns, including self-loading. The disadvantage of this solution is the limited speed of the shotgun projectile by the size of the powder charge chamber.

The technical result of the claimed utility model is to increase the flight speed of a shot projectile while maintaining the advantages of the above counterparts.

Brief Description of the Drawings

Figure 1 shows the design of the cartridge for smoothbore guns, where 1 is the cartridge case, 2 is the gasket for the shot, 3 is the plastic wad, 4 is the shotgun, 5 is gunpowder, 6 is wood-fiber wad, 7 is gunpowder , 8 - shock absorber, 9 - diaphragm with a hole, 10 - 1st part of the propellant (powder) charge, 11 - 2nd part of the propellant (powder) charge, 12 - igniter capsule. Figure 2 shows a whole view of the cartridge in section.

Device essence

The claimed technical result is achieved due to the fact that the cartridge for smoothbore guns containing (see Figure 1 and Figure 2) a sleeve (1), a wad (3), a shotgun shell (4), a charge of gunpowder (5), a capsule - an igniter (12) characterized in that the powder charge is divided into two chambers by a diaphragm (9) with an opening. The wad may be made of plastic (3) and contains a shock absorber (8). Wad may be made of wood-fiber (6). Each of the propellant (powder) charges separated by the diaphragm (9) with the aperture (10), provides acceleration of the shot projectile due to the pressure of the powder gases released during the combustion of this part of the charge. The diaphragm (9) with the hole provides sequential combustion of parts of the propellant (powder) charge to increase the speed of the shotgun. Wad (3), (6) provides the opportunity

the tight assembly of the components of the cartridge in the sleeve, contributes to the obturation of the powder gases, dispersing the powder charge in the barrel. Wad (3) should be used together with a shock absorber (8), which provides with it an accelerated shot of a fraction. Plastic wad (3) and shock absorber (8) (see Figure 1 (6)) can be replaced with wood-fiber wad (6) (see Figure 1 (a)), the structure of which simulates the shock absorber when fired.

At the moment of operation of the igniter capsule (2), the 1st part of the propellant (powder) charge ignites (10). In the process of combustion of which the impulse of the shock is already transmitted to the wad and shotgun. By the moment the shot leaves the cartridge, the 1st part of the charge burns out and through the hole in the diaphragm (9), the 2nd part of the charge (11) ignites, which gives an additional impulse impulse. As a result, the fraction flies out at a faster speed than usual when using single-chamber charges.
