Abstract

FIELD: weapons and ammunition.

SUBSTANCE: invention relates to automatic weapon ammunition supply systems. Ammunition supply system comprises guide neck with moving and fixed parts. Movable part consists of a series set of cylindrical bushings with holes for passage of the cartridge belt and is placed in the pipe rigidly attached to the fighting module coaxially to axis of rotation of the weapon. Fixed part provides turning cartridge belt from position of cartridges perpendicular to axis of barrel to position along axis of weapon at entry into movable part.

EFFECT: reduced moment of inertia of movable part of system, simplified design of power supply system.

Description

The invention relates to military equipment, to automatic weapons with tape power.

Known grenade launcher (Patent No. 2222759 from 02.13.02, IPC F41A 23/28), located on the tower of a combat vehicle. The installation includes a grenade launcher and a store in which grenades equipped with tape are vertically mounted. The tape is brought to the grenade launcher through a guide neck with rollers and a pipe fixed along the axis of rotation of the grenade launcher. The disadvantage of the grenade launcher is its large overall dimensions.

A known power system for automatic weapons (Patent No. 2406052 of 07/14/2009, IPC F41A 9/57). The power system of an automatic weapon contains a guide neck fixed at one end to the weapon receiving window, and at the other end to a magazine with cartridge strip. The guide neck is made of two telescopically connected parts in the dimensions of the cartridge with a link, taking into account the clearance for the passage of the cartridge strip. The lower part of the neck is inserted into the upper part of the neck mounted on the weapon. The bending radius of the necks at the junction coincides with the horizontal axis of rotation of the weapon.

The disadvantage of the power system is its limited scope, due to the need to combine the axis of rotation of the weapon and the radius of bending of the tape. If the axis of rotation of the weapon is located relative to the longitudinal axis of the feed cartridge at a distance less than the minimum radius of the bend of the tape, the application of this technical solution is impossible.

Another disadvantage is the large vertical dimensions.

A known power system for automatic weapons (Patent RU No. 2509972 of 03/20/2014, IPC F41A 9/29), selected as a prototype. The power system contains a guide neck. The neck is made of two parts: movable, fixed on the weapon and fixed, fixed on the store with a cartridge strip. The fixed part of the neck is V-shaped. The movable part of the throat guide is curved in the form of a loop, ensuring the direction of the cartridge strip parallel to the axis of the barrel with the nozzles of cartridges outward, and at the entrance to the weapon with the nozzles of cartridges in the direction of fire.

The disadvantage of the automatic weapon power supply system is the large moment of inertia of the moving parts of the system and the complex trajectory of the belt with cartridges in the moving part of the neck.

The objective of the proposed invention is to reduce the moment of inertia of the moving part of the system and simplify its design.

The problem is solved by the power supply system of automatic weapons located in the combat module of the combat vehicle, including a guiding neck made of two parts: movable, fixed on the weapon and fixed, fixed on the magazine with a cartridge tape mounted inside the combat module. What is new is that the movable part of the guide neck is made in the form of a set of cylindrical bushings with windows for the passage of the cartridge belt, the bushes are placed in a pipe rigidly fixed to the wall of the combat module coaxially with the axis of rotation of the weapon, and the fixed part of the guide neck is made to ensure the rotation of the cartridge belt from the position of the cartridges perpendicular to the axis of the barrel with the nozzles from the weapon, and at the entrance to the movable part of the throat guide, with the cartridges nose in the direction of fire.

The proposed technical solution is illustrated by graphic materials, where in FIG. 1 shows a general view of the power supply system for automatic weapons located in the combat module, FIG. 2 is a general view of the power system of an automatic weapon; FIG. 3 is a general view of the movable part of the neck located in the pipe, in FIG. 4 - design of the movable part of the neck.

The power supply system for automatic weapons is located in the combat module 1 of the combat vehicle. The power supply system includes a neck made of a movable part 2, mounted on a weapon 3 and a fixed part 4, mounted on a magazine 5. The movable part of the neck 2 is made in the form of a set of cylindrical bushings 6 with windows 7 for the passage of the cartridge strip. The bushings 6 are placed in a pipe 8, rigidly fixed to the wall of the combat module 1. The movable part of the neck 2 is fastened to the bracket 9, which is rigidly fixed to the cradle 10 of the weapon 3.

The power system of automatic weapons works as follows. When firing automatic weapons, the cartridge strip leaves the store and is sent to the V-shaped part of the fixed part of the neck. Cartridges from the store come out perpendicular to the direction of shooting with weapons spouts. In the V-shaped part, the tape unfolds and the cartridges approach the moving part of the neck with nozzles in the direction of fire. When the weapon is vertically pointed, the cartridge strip in the movable part of the neck is twisted together with cylindrical bushings, the windows of which form a channel, providing a smooth turn of the tape and its entry into the receiving window of the automation.

Thus, the proposed technical solution allowed to reduce the moment of inertia of the moving part of the system and simplify the design of the power system.
