RU2598877C2 - Universal shell with propellant charge and projectile - Google Patents

Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to ammunition, specifically to cartridges for smooth-bore guns and can be used for shooting from 12, 16 calibre smooth-bore guns. Universal shell with propellant charge consists of shell flange, metal base of shell, polyethylene or plastic shell, powder. Instead of shot or bullet, universal shell used is harpoon, which is equipped with piston rings, which powder gases are pushed out of channel of smooth-bore gun. Harpoon is not integrated with universal shell, and is connected to shell through muzzle bore gun before shooting. Monitoring of location of harpoon after shooting is performed using a cord, one end of which is located movable ring of harpoon, and second end is wound on a coil, which is located next to gun and unwinds at moment of shooting.

EFFECT: result is possibility of firing harpoon from 12 and 16 calibre guns.

Description

The invention relates to ammunition, and in particular to the design of cartridges for smooth-bore guns and can be used for firing from smooth-bore guns 12, 16 calibres.

Known cartridges (patent RU No. 2102693; England patent No. 1273208, class F42B 13/00, 05/03/72; French patent No. 917369, class Gr 11, Cl 4, 01/06/47)

The closest analogue, which is selected for the prototype, is the patent of England No. 1273208, class. F42B 13/00, 05/03/1972.

The disadvantage of a fractional cartridge, known for the prototype, is that it can only be equipped with a fraction or a bullet.

The author developed the design of the cartridge (Fig. 1), which allows the use of a projectile instead of a bullet or shot with a powder charge. The cartridge contains: sleeve flange - I, metal base of sleeve - II, polyethylene or plastic sleeve - III, gunpowder - IV.

The projectile is a harpoon (Fig. 2), which consists of: body - V, a movable ring on its body - VI.

On the body at the base of the harpoon in a circle there are two grooves for installing piston rings in them for holding powder gases after firing. Powder gases will exert pressure on the harpoon body with rings, which will move along the channel of the smoothbore gun.

The harpoon is tightly inserted through the muzzle of a smoothbore gun up to the cartridge with a charge of gunpowder without a bullet and shot.

A cord is attached to the harpoon's movable ring connecting it to the coil (Fig. 3).

After placing a universal sleeve with a propelling charge (gunpowder), the base of the harpoon body with piston rings is tightly inserted through the barrel of a smooth-bore gun until it contacts the cartridge sleeve. At this point, the movable ring is on the harpoon from the outside of the barrel. After ignition of the propellant propellant charge, the gases push the harpoon body out of the barrel of the shotgun using piston rings. After the harpoon leaves the gun barrel, the movable ring is located at the base of the harpoon, next to the piston rings, and pulls the cord. The control of finding the harpoon after it is shot is carried out by this cord, one end of which is located on the movable ring of the harpoon, and the other end is wound on a reel for the cord.
