Description

Artillery shell

The utility model can be used, for example, both for military purposes as a fragmentation-destruction weapon, and for auxiliary purposes as combat training and range tests.

The utility model (1) describes a bullet containing several radial segments made of solid, heavy metal and a tail made of lighter metal with the possibility of fixing segments. The disadvantage of this device is the implementation of the radial segments from expensive materials, in particular, from tungsten, bronze, copper, etc. Therefore, the use of these materials for the manufacture of artillery shells having a caliber of more than 20 mm is impractical.

Known is an armor-piercing bullet (2) containing a shell with steel and lead cores placed in it, and the core is made of high-strength steel with a hardness of HRC 60 and has a conical head part. This device is characterized by the complexity of the design, as well as the presence of expensive materials.

The closest analogue to the claimed device is a bullet of a sports cartridge for non-military weapons (3), containing a metal shell with a plastic core placed in it, on the tail of which a lead ring is installed

IPC F42B 12/74

The inventive utility model is aimed at creating an artillery shell based on the use of cheaper materials while providing tactical and technical parameters and expanding the functional tasks performed.

The essence of the utility model is that the shell of the projectile is made of a composite material consisting of a filler and a binder, while the lead belt is made of synthetic polymer, for example, caprolon, and the body is equipped with a guide ring installed in its head part. A composite material as HanojmHre.M contains powdered silicon carbide and carbon black, and as a binder a powder phenolic compound, for example, pulverbakelite in the ratio of components, May. %: silicon carbide - 60-70, technical carbon - 20-30 and pulverbakelite - 10-20, while the body is made by pressing with subsequent silshivshivanie.

In addition, natural clay, for example, refractory clay of the Pechersky deposit, can be used as a composite material, while the body is made using slip casting followed by heat treatment in the ratio of slip components, May. %: clay - 45-65, the rest is distilled water.

Additional differences of the utility model are some congrugging and 1xx ms1ric parameters of the projectile elements, namely; the ratio of body length to caliber is 4-6; the head of the body is made in the form of a cone 1.8-2.0 caliber high with a radius at the apex of 0.1-0.2 caliber; the guide ring is made of alloy steel, for example, grade 11YA 0.8-1.0 gauge in length and has an outer bevel that is a continuation of the cone of the head of the shell body; the lead belt has a length of 0.2-0.3 caliber and is installed

at a distance of 0.8-1.0 caliber from the end of the tail of the hull; at least two annular grooves for securing the projectile in the sleeve of the powder cartridge are made on the tail of the housing in the section from the end to the leading girdle.

The manufacture of the shell of the shell from a composite material containing silicon carbide and carbon black, in addition to reducing the cost, provides satisfactory tactical and technical characteristics of the shell, including the parameters of shrapnel-damaging effects, and the manufacture of the shell of natural clay will even more reduce the cost of the final product . The implementation of the lead belt of polymer material is also aimed at reducing the cost of the projectile while maintaining its technical parameters in relation to firing from a rifled weapon.

The quantitative content of the components of the composite material, as well as the geometric parameters of the structural elements of the projectile are determined by calculation and confirmed by firing tests in polygon conditions. The tests were carried out on a firing test setup (SIU 30,) j developed by FSUE TsNIIM and designed to evaluate the functioning of a projectile in a real shot.

For the manufacture of cases of composite material according to claim 2, the formula used was filler material made of green silicon carbide green (GOST 26327-84) grade 64C with a grain size of 10P.N and M28 (GOST 3647-80) and technical carbon (GOST 7885-86) and as a binder - poropps pulverbakelite grade SFP 012A (TU 6-05-441-78).

For the manufacture of buildings made of composite material according to claim 4, refractory clay of the Pechersky deposit was used (TU 21-0288962-1-89).

To prepare the leading belt and guide ring, caprolon of grade B (MRTU 6-05-988-66) and alloy steel of the ПУА grade (GOST 803-81) were used, respectively. The test results confirmed the possibility of serial production of artillery shells from non-metallic composite materials.

The inventive utility model is illustrated in the drawing, which shows a longitudinal section of a projectile consisting of a housing 1, a leading belt 2 and a guide ring 3.

Using the utility model will allow you to get cheaper artillery shells with tactical and technical characteristics at the level of freelance items.
