Description

The invention relates to the field of engineering and is intended for throwing solids, shells and can be used in various industries, as well as for the design and manufacture of rifled, smooth trunks of various types and ammunition for them.

Known products the barrel of a firearm (Patent RU No. 2150063 of 03.25.1999 IPC 8 F41A), the pallet for a sub-caliber weapon projectile (Patent RU No. 2258892 of 02.04.2004 IPC F41B) have a fundamentally similar design of ammunition for both rifled and smooth-bore weapons with a muzzle brake, from small to large calibers, with tabular tactical and technical characteristics and allows you to perform tasks at specific ranges with a certain accuracy.

The disadvantage of existing barrel systems and their ammunition is a significant limitation in the capabilities of recoil devices and a muzzle brake compensator, which does not significantly increase the charge power, and therefore increase the firing range.

The objective of the invention is the creation of ammunition for shells with a straight, not narrowed by a truncated cone, bottom of the hull, which will significantly reduce the pitch of the rifling, as well as significantly improve the capabilities of the muzzle brake compensator, and thus increase the charge power and thereby increase the table firing range.

As a result of its use, a technical result can be obtained in which conditions appear for a significant improvement in the capabilities of the muzzle brake compensator, thereby both significantly reducing the rifling pitch and significantly increasing the table ranges

firing, which allows you to design products compactly, both for the old and for new requirements, technical specifications and parameters.

The solution of this problem, for shells with a bottom part of the shell narrowed by a truncated cone, is achieved by the proposed “shell pod” (hereinafter - PS pan) by positioning it on the bottom of the shell body, tapering into an aerodynamic cone with the cone tip pointing towards the charge side, s longitudinal, through ignition channel of the tracer element in the center of the PS tray.

The characteristics of the PS pallet vary depending on the tasks to be solved, by changing all structural elements tied into a single whole.

In the SS pallet that we offer, the improvement of the muzzle brake capabilities for shells with the bottom part of the shell narrowed by a truncated cone is achieved due to the PS pallet located on the shell of the shell, tapering it to the aerodynamic cone with the tip of the cone pointing towards the charge side, s a longitudinal, through ignition channel of the tracer element in the center of the PS pallet, which allowed both to significantly reduce the groove pitch and significantly increase the tabular range by that permits the construction of compact products, both for the old and for the new requirements, technical specifications and parameters.

The essence of the proposed pallet PS for shells with a narrowed to a truncated cone, the bottom of the hull is shown in the drawing.

The PS pallet (Fig. 1) consists of the PS pallet body (1) located on the bottom of the truncated cone shell shell (2), the aerodynamic cone (3), the ignition channel of the tracer element (4),

part of the body of the muzzle brake compensator (Fig. 2), the combat surface of the muzzle brake compensator (5), the stray part of the muzzle brake compensator (6), i.e. the parasitic part, acting on which the powder gases have a parasitic effect, counteracting the operation of the muzzle brake compensator.

The PS pan (1) directs the powder gases to the combat surface of the muzzle brake compensator (5).

The proposed device operates as follows.

The PS tray (1) (Fig. 1), moving with the projectile in the barrel channel, through the ignition channel of the tracer element (4), in the center of the PS tray (1), ignites the tracer element in the bottom of the projectile (2).

Powder gases, as the projectile (2) with the PS pan (1) exits, exit the barrel along the truncated cone of the projectile (2) towards the combat surface of the muzzle brake compensator (5), restraining the rollback movement. Gradually, the powder gases, as the projectile (2) with the PS pan (1) continues to exit, continue to exit the barrel along the aerodynamic cone (4) towards the combat surface of the muzzle brake compensator (5), bypassing the aerodynamic cone (4) ) the parasitic part of the muzzle brake compensator (6), while continuing to restrain the rollback movement.

Claims (2)

1. The shell tray (hereinafter - the PS tray), located on the bottom of the shell of the shell and characterized in that the PS tray is made tapering into an aerodynamic cone with the direction of the top of the cone in the direction of the charge. 2. The PS pallet according to claim 1, characterized in that in the center there is a longitudinal through channel of ignition of the tracer element.
