Description

The invention relates to ammunition for small arms automatic weapons having a high initial bullet speed, good stopping power, and also lower recoil.

Ordinary bullets, designed to hit living targets, are shell and solid. The first consists of a lead core and outer shell. The shell is cupronickel, bimetallic (i.e., iron, covered with a thin layer of metal that protects the iron from corrosion and reduces the friction of the bullet in the bore) and iron. Solid bullets are made of special alloys (French bullet - tompakova) (A. A. Blagonravov. Material of small arms. Volume 1. Modern weapons. Ammunition. Magazines rifles. Oborongiz NKAP. Main edition on armament and ammunition. Moscow, 1945. , p. 78).

A disadvantage for most bullets with a lead core is that they form significant contamination on the tracks in the dash during training firing and competitions. In addition, they have kinetic energy that does not dissipate for a long time. As a result of this, when used in public places, they are capable of hitting two people, one after another. Because of this, they may not be applicable for use by the police.

The so-called "super-speed" bullets developed in France are known, which received the designation THV.

The cartridges equipped with these bullets are shown in pos. 56, 118, 131 (A.B. Zhuk. Small arms. Revolvers. Pistols. Rifles. Submachine guns. Assault rifles. Moscow. Military publishing house. 1992, pp. 112 and 414. THV lightweight bullet with a large cavity inside and with a head part of a special shape.With a significant increase in the initial speed, it provides an increased damaging effect.When faced with an obstacle, a kind of cumulative effect occurs in which the energy of the bullet is directed (formed) to the sides around the circumference. These standard bullets can be equipped with various standard cartridges for the revolver and pistols.

The disadvantage of the cartridges equipped with these bullets is the low reliability of sending manual automatic weapons to the chamber.

Known bullet intended mainly for the police and special services.

The bullet consists of an approximately conical tip and a cylindrical bottom. The tip has a cone between 30 and 45 degrees, preferably 38 degrees. The tip has a central flat portion of a circular shape in diameter between 10 and 50% of the diameter of the bullet in the main part of the tip or bottom. The central flat part has a diameter between a quarter and a third of the diameter of the bullet. At least two recesses are arranged symmetrically on the side of the tip. The number of recesses and their angular location is selected depending on the caliber of the bullet. The bullet is hollow and a central blind hole is made in it. The bullet is preferably made of a relatively soft metal, for example copper or its alloys. The described bullet in caliber 9 mm parabellum weighs 5.6 g (Patent for invention FR 2846084 from 10.17.02).

The disadvantage of the cartridges equipped with these bullets is the low reliability of sending manual automatic weapons to the chamber and the high cost of ammunition.

The objective of the invention is:

- ensuring reliable sending of cartridges equipped with a light high-speed bullet into the chamber of a hand-held automatic weapon;

- reduction in bullet weight;

- reduction in the cost of ammunition.

According to the invention, the task is achieved by the fact that in a light high-speed pool containing a core having a head part with a flat front surface and a leading part of a cylindrical shape, inside of which a blind hole is made:

- the core is made of aluminum alloy;

- the core is enclosed in a shell having a head, leading and tail parts;

- the head part of the core is conical in shape and in its middle part an annular groove is made in which the front part of the shell is placed;

- the shell is made of bimetal;

- on the cylindrical part of the core can be made of at least two annular grooves.

The essence of the invention is illustrated in the drawing, where figure 1 shows a partial longitudinal section along the pool.

A light high-speed bullet contains a core 1 and a sheath 2. The head part of the core is made of conical shape 3, in the middle part of which there is an annular groove 4, the rest of it is cylindrical in shape 5. The head part of the core is made flat in front 6. Inside the core there is a blind hole 7. Core enclosed in a shell having a head 8, leading 9 and tail 10 parts. The front part of the shell 11 is placed in the annular groove 4 of the core 1. At least two annular grooves are made on the cylindrical part of the core 12. The tail part 10 of the shell, excluding the possibility of deformation of the rear part of the bullet when fired, ensures the reliability of the obturation of powder gases (in the prototype for this purpose the presence of steel obturation parts). The core is made of aluminum alloy, and the shell is made of bimetal.

The implementation of the head part of the conical shape of the core, smoothly interfaced with the head part of the shell, made it possible to solve the problem of the reliability of sending the cartridge into the chamber of the barrel channel of a hand-held automatic weapon. The implementation of the core of an aluminum alloy, a shell of bimetal, as well as the absence of special devices to provide an obturation of powder gases during firing allowed to reduce the weight of the bullet (the weight of the bullet in the caliber of 12.7 mm is 7.0 g) and make its manufacture cheaper.

When conducting ammunition tests, the verification of semi-shell bullets is of particular relevance to determine their compliance with international humanitarian law (IHL). The latter are a combination of legal principles and norms contained in international treaties regulating relations between states during an armed conflict and aimed at protecting basic human rights and freedoms, humanizing war.

The prohibited means of warfare in relation to small arms ammunition include bullets that are easily deployed or flattened in the human body, the hard shell of which does not cover the entire core or has cuts (The Hague Declaration, 1899, The Hague Conventions, 1907, Article 6 of the Guide to application of IHL standards).

Tests to determine the resistance of bullets made according to the invention to dismantling, carried out on simulators of human soft tissues, confirmed the correctness of the selected technical solutions.

The proposed bullet consisting of 12.7 mm cartridge along with the prototype of the machine passed the full cycle of tests provided for by the normative and technical documentation and terms of reference with positive results.
