Abstract

The utility model relates to ammunition for under-barrel grenade launchers that are mounted under the barrel of AKM, AK-74 Kalashnikov assault rifles and is designed to destroy openly located manpower.

Currently, in the conduct of hostilities, 40-mm grenade launchers are widely used, for firing from which grenade launchers with fragmentation, high-explosive and incendiary grenades are used.

But when conducting military operations in urban conditions, in direct contact with the enemy, situations arise when it is necessary to fire at a target located at a minimum distance of 6-8 m from the shooter. Under these conditions, it is necessary to have ammunition that has great destructive ability and is safe for the shooter.

Existing grenade launcher shots are highly effective, but the use of a explosive explosive charge in a grenade design in practice leads to the destruction of a firing explosive by striking factors (shock wave, overpressure, specific pressure pulse) and fragments generated in significant quantities at crushing the case, when using a grenade launcher in rooms, basements and trenches.

In order to increase the effectiveness of grenade launcher weapons and ensure the safety of firing during combat operations in urban conditions in direct contact with the enemy in the premises, basements, and trenches, a grenade launcher with ready-to-use striking elements is proposed.

A grenade launcher with ready-to-use striking elements consists of a propellant charge with an igniter capsule, a pyrotechnic retardation device, which is fixed to the bottom of the grenade body using a thread, an expelling charge located in the lower part of the chamber, the warhead of the grenade and designed to create pressure of powder gases, under the influence of which the equipment is ejected from the grenade body, the diaphragm, ready-to-use striking elements placed in the grenade body, and the wad intended for udder Ania damaging elements in the assembly.

Description

The utility model relates to ammunition for under-barrel grenade launchers that are mounted under the barrel of AKM, AK-74, etc. Kalashnikov assault rifles, which are in service with the airborne troops, reconnaissance units and special forces. A grenade launcher with ready-to-use striking elements is designed to engage openly located manpower.

Currently, for firing from 40-mm grenade launchers that are mounted under the barrel of AKM, AK-74, type GP-25, and GP-30 Kalashnikov assault rifles, grenade launchers, both main and special, are widely used.

Known main-purpose shots with high-explosive, high-explosive, and incendiary grenades, special-purpose shots with lighting smoke and gas grenades.

When conducting military operations in urban conditions, in direct contact with the enemy, it is necessary to have ammunition that has great destructive ability and is safe for the shooter using them.

A shot with a fragmentation grenade has a high efficiency in defeating manpower, since the presence of a shell leads to the formation of a significant number of fragments flying over a distance of 15-18 m, which limits the use of a grenade launcher in rooms, basements and trenches due to the possibility of hitting a shooter [1] .

To some extent, the noted shortcomings were eliminated in the design of a grenade launcher shot [2] containing a shell, a propellant charge with an igniter capsule and a projectile consisting of a burst charge placed in a plastic shell without a gap, and an explosive device mounted without a gap in the burst charge cavity, characterized in that in it an explosive device is installed in a cavity made inside a bursting charge consisting of two half charges, while the distance from the side surface of the explosive device and from its rear end to the outer side surface of the explosive charge is 1.0 ÷ 1.2 of the critical diameter of the explosive, and the distance from the front end of the explosive device to the top of the explosive charge is 1.1 ÷ 1.5 caliber shots.

The proposed design of the grenade launcher increases the safety of the shooter with a minimum range of combat use by reducing fragmentation while maintaining the effectiveness of the target.

The disadvantage of this design is the presence of a bursting charge made of explosives, which can lead to the destruction of the shooter by the damaging factors of a high-explosive action (shock wave, overpressure, specific impulse).

When conducting combat operations in urban conditions, situations arise when it is necessary to fire at a target located at a minimum distance of 6-8 m from the shooter [3]. For this, it is necessary that the stream of fragments be directed towards the target, and the shooter himself is not affected by the damaging factors of the grenade.

A grenade launcher shot consists of a combustion chamber located in the rear of the grenade with an external profile under the pre-chamber of the grenade launcher barrel, which contains a propelling charge with an igniter capsule and a warhead, in the housing of which are prepared ready-to-use striking elements of an elongated shape, an outburst charge and a diaphragm.

In this design, the presence of a knockout charge made of smoke powder and ready-made striking elements of an elongated shape, weighing 1.6 g, diameter 2 mm and length 50 mm, a total of 128 pcs., Increases the efficiency of the grenade, both in open areas and and in the conduct of hostilities in urban areas and reducing the safe distance to the target (3-4 m), which allows the use of a grenade launcher in rooms, basements and trenches.

The objective of this utility model is to increase the effectiveness of a grenade launcher in close combat, in direct contact with the enemy, both in confined spaces and in open areas. This is achieved due to the fact that in a grenade launcher shot consisting of a warhead and a combustion chamber located in the rear of the grenade with an external profile under the front chamber of the grenade launcher containing a propelling charge with an igniter capsule, ready-made striking elements of an elongated shape are placed in the warhead housing, which, when fired under the influence of powder gases of an expelling charge, fly out toward the target with an additional speed, which is safe for the shooter. This technical solution is illustrated by graphic materials.

In FIG. 1 shows a grenade launcher.

In FIG. 2 shows a pyrotechnic retardation device.

A grenade launcher includes the following elements:

1 - propellant charge; 2 - igniter capsule; 3 - pyrotechnic retarding device, 4 - knockout charge, 5 - diaphragm, 6 - ready-made striking elements of an elongated shape, 7 - grenade body, 8 - wad.

To transmit a beam of fire from a propellant charge to a knockout charge, a pyrotechnic retardation device is used.

Pyrotechnic retardation device includes:

9 - a sleeve; 10 - moderator; 11 - igniter; 12 - pyrotechnic amplifier; 13 - sleeve regulator with a calibration hole.

The pyrotechnic retardation device is fixed to the bottom of the grenade body using thread.

A grenade launcher operates as follows.

When fired, the grenade launcher firing pin punches the igniter 2. A beam of fire from the igniter 2 ignites the propellant charge 1, the grenade flies out of the barrel of the grenade launcher at a speed of 76 m / s. Flame propellant charge, through the sleeve of the regulator with the calibration hole 13 is transmitted to the igniter 11 pressed into the sleeve 9, then to the moderator 10 and ignites the pyrotechnic amplifier 12. The powder gases formed during the combustion of the pyrotechnic amplifier 12 ignite the expelling charge 4 of the grenade. The powder gases of the expelling charge 4 through the diaphragm 5 eject the finished striking elements of an elongated shape with an additional speed of 25-30 m / s.

Thanks to the heated powder gases, paraffin melts and under the influence of centrifugal force, the finished striking elements fly apart, forming a cone with an angle of 18 ° at the apex, and strike openly located manpower.

The proposed design of a grenade launcher increases the effectiveness of grenade launchers with a minimum range of combat use in urban areas, due to the directional action of the finished striking elements towards the enemy, while reducing the safe distance to the target, and increases the safety of the shooter since there is no explosive charge made of explosive in the design, which eliminates the shooter's defeat by high-explosive damaging factors and fragments generated during the destruction of the grenade’s body, which makes it possible to use the grenade launcher in rooms, cellars and trenches in direct contact with the enemy.
