Abstract

FIELD: small arms.SUBSTANCE: invention relates to ammunition of small arms. Cartridge without bullet, characterized in that it contains body with cavity inside its tail part, in which powder charge is located. Inside powder charge at the end of cartridge combustible electrode is installed, isolated from body through combustible dielectric. Powder charge is made of two parts: first part – from powder charge of fast burning, second – from delayed burning, and ampulized by radial reduction of end of cartridge tail part. Shot occurs due to embedding of bullet in electric circuit and initiation of electric discharge between combusted electrode, located in tail part of bullet, and bullet body inside powder charge. Absence of capsule and sleeve allows target to be defeated using all ammunition, and also to simplify and reduce cost of production technology. Caseless cartridge has straight cylindrical shape, that enables to abandon complex reciprocating mechanism for sending conical cartridge into barrel of small arms.EFFECT: shot is carried out with co-axial alignment of barrel of weapon and cartridge without use of firing mechanism, which also makes it possible to simplify design of small arms and increase its rate of fire.1 cl, 2 dwg

Description

The invention relates to ammunition of small arms. Known patents for inventions sleeveless cartridge RU 2413167, RU 229759, RU 2170908, RU 2186318, the common disadvantage of which is the complex design, expensive technology for the manufacture of ammunition.

An object of the invention is to simplify the design and reduce the cost of manufacturing ammunition. The solution to this problem is achieved through the manufacture of a bullet with a cavity inside the tail part, in which the powder charge 2, 3 is located (Fig. 2). Inside the powder charge at the end of the cartridge is a combustible electrode 4 (Fig. 2), isolated from the housing through a combustible dielectric 5 (Fig. 2). The cartridge is amputated due to the radial compression of the end of the tail of the cartridge. A shot of a cartridgeless cartridge may accompany an additional sound (whistle), formed due to turbulences in the cavity of its tail, which will unmask the arrow. To eliminate this negative effect, it is possible to use two types of powder charge. The first part of the powder charge of rapid burning fires a bullet 3 (Fig. 2), and then the second part of the slow combustion 2 (Fig. 2), performs a reactive movement of the bullet to the target. The initiation of the shot occurs due to the breakdown of the spark in the gap between the body of the bullet 1 (Fig. 2) and the combustible electrode 4 (Fig. 2) inside the powder charge 3 (Fig. 2), (see patent for the invention RU 2656446).

The straight cylindrical shape of the cartridgeless cartridge allows you to abandon the existing traditional system for feeding a conical cartridge into the barrel of a small arms. The supply of a cartridgeless cartridge from the magazine to the barrel of a small arms is possible using a reel according to the Nagan system (see patent for invention RU 2656446). The absence of a capsule and a sleeve greatly simplifies and cheapens the manufacturing technology of a cartridgeless cartridge, and also defeats the target using the entire ammunition. The design of a cartridgeless cartridge allows the use of small arms cartridge technology RU 2591542, which will significantly increase its stability in flight and its striking properties. The claimed invention is illustrated by drawings, where in FIG. 1 shows the appearance of a cartridgeless cartridge, and FIG. 2 is a schematic illustration of a cartridgeless cartridge.

The positions in the figures are indicated:

1 - bullet;

2 - powder charge of slow combustion;

3 - powder charge of rapid burning;

4 - combustible electrode; 5 - combustible dielectric.
