Abstract

 A cartridge for a firearm containing a cartridge case, a combat charge, an igniter capsule and a single-element chiseled bullet, characterized in that the bullet is made of steel.

Description

The utility model relates to military equipment and can be used in the development of ammunition for small arms.

Cartridges for firearms of calibers 12.7 × 108 mm, 7.62 × 54 mm and others are known, containing a sleeve, an igniter capsule, a combat charge and a multi-element bullet with steel and lead cores sequentially located in the shell (see V.K. .Zelenko, A.V. Bryzzhev and others. "Pistol and sniper cartridges. Grenade launchers", Tula, "Infra", 2008, p. 47 ÷ 52, fig. 2.3 a, b, e, f).

The disadvantages of these cartridges are:

- the complexity of the design and the high cost of manufacturing a bullet;

- environmental hazard, both at the manufacturing stage and during use, due to the presence of a lead core;

- the inevitability of the eccentricity of the assembly of individual elements, which reduces the accuracy of the battle.

Closest to the proposed cartridge for firearms is, adopted for the prototype, a cartridge of 12.7 × 108 mm caliber, containing a sleeve, an igniter capsule, a combat charge and a single-element bronze chiseled bullet (see also Fig. 2.3 c).

However, this cartridge is characterized by high cost due to the high cost of bronze (260 ÷ 360 rubles / kg) and low combat effectiveness associated with low armor-piercing action, due to the low strength of bronze (σ _in = 32 ÷ 35 kg / mm ² ), its low hardness and the impossibility of hardening.

The objective of the proposed utility model is to increase the combat effectiveness of firearms cartridges and reduce the cost of their manufacture.

The problem is achieved in that in the proposed cartridge for a firearm containing a sleeve, a primer, a combat charge and a single-piece chiseled bullet, the bullet is made of steel.

The essence of the utility model is illustrated by drawings, where figure 1 shows the design of the proposed cartridge for a firearm; figure 2 is a diagram of the functioning of this cartridge in the barrel of a weapon during firing.

The proposed cartridge for firearms (figure 1) has a sleeve 1, a combat charge 2, a primer 3 and a single-piece steel chiseled bullet 4; figure 2 shows the proposed cartridge, placed in the barrel 5 of the weapon.

The proposed cartridge (Fig. 1) functions as it is fired as follows (Fig. 2): after the ignition capsule 3 is activated, the warhead 2 is ignited and the powder gases generated in this case eject the single-element turned steel bullet 4 from the sleeve 1 and provide translational and rotational movement bullets in the barrel bore 5 weapons.

In comparison with the prototype of the proposed cartridge has the following advantages:

- high combat effectiveness, as sufficient armor-piercing action is achieved due to the higher mechanical properties of the material of a single-element steel bullet and the possibility of ensuring hardening of its warhead and at the same time increasing the charge of the cartridge, increasing the initial velocity of the bullet and, as a result, the firing range;

- low manufacturing cost of the cartridge as a whole, because the price of the bullet material is 20 ÷ 40 rubles / kg.

In addition, the high initial speed of a single-element chiseled steel bullet provides less flight time to the target, improves trajectory stability, resulting in improved accuracy and accuracy, reduced aiming errors and increased probability of hitting the target.

Thus, the proposed cartridge for firearms has high combat efficiency at a lower manufacturing cost.
