Abstract

FIELD: weapons and ammunition.

SUBSTANCE: power system of automatic gun consists of 3-sectioned magazine with output channels and arms for guiding cartridge belt, the flexible element and the neck, divided into two channels for supplying two cartridge belts. The magazine sections are arranged parallel to each other. Between the first and second magazine sections there is a flexible element made in the form of an upper and lower flexible arms, one ends of which are fastened to the receiving windows of the gun, and the others - to the vertically mounted necks. The necks are connected by flat curved guides with the output channels of the first and second magazine sections respectively. The second and third magazine sections are mounted adjacent to each other and interconnected from above by a curved guide.

EFFECT: reduction of the length of power paths, reduction of dimensions of power system, increase in reliability of the gun operation.

Description

The invention relates to military equipment, to small arms and cannon installations with two-tape power automatic weapons.

A known power system for automatic weapons (Patent No. 2406052 of 07/14/2009, IPC F41A 9/57). The power supply system 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 of automatic weapons is their large overall dimensions, which makes it difficult to place the power system inside the combat module with limited dimensions.

A known power system for a gun with two-belt power BMP-2 infantry fighting vehicle (BMP-2 infantry fighting vehicle. Technical description and operating instructions. Part 1. Moscow. Military publishing house, 1987), selected as a prototype. The gun’s power system is designed to accommodate and feed cartridge belts to the gun’s receiving windows and includes: a magazine, a left sleeve and a right sleeve, a pull-up mechanism, a screw sleeve, a neck and a flexible element. The store is attached to the floor of the fighting compartment, is a rigid welded structure and consists of left and right compartments with covers. In the right compartment are the cartridge tapes equipped with cartridges with armor-piercing tracer (BT) shells, in the left compartment - equipped with cartridges with high-explosive fragmentation incendiary (HE) and fragmentation-tracing (OT) shells.

The left compartment is divided into two parts by a partition. The compartments are provided with output vertical channels.

The left sleeve and the right sleeve are designed to accommodate and feed the tape from the magazine compartments to the pull-up mechanism. Sleeves are fixed around the perimeter of the floor.

The screw sleeve and the neck are used for placement, rotation and supply of cartridge tapes from the pull-up mechanism to the flexible element. The screw sleeve and the neck are rigid welded structures, divided into two channels for the passage of two cartridge strips.

The flexible element provides the supply of cartridge tapes from the fixed neck to the receiving windows of the gun at all pumping angles. The flexible element is made in the form of a package of plates pumped relative to the pipe mounted on the clip of the weapon block. The tail part of the plate rests on a rod pivotally mounted on the casing of the gun and on the neck. When pumping the gun, the rod rotates the plates of the flexible element with a fan. The windows in the plates form two channels for guiding the cartridge strips.

The disadvantage of the power system is the large length of the paths for supplying the cartridge belt to the weapon, as well as unreliable operation due to the possibility of the shell nose dropping into the formed gaps between the plates of the flexible element when the gun is elevated and inclined, which results in damage to the cartridge and jamming of the cartridge belt.

The objective of the invention is to reduce the length of the power paths of the gun, reducing the overall dimensions of the power system while maintaining the ammunition and increasing the reliability of its operation.

The problem is solved by the power supply system of an automatic gun, consisting of a 3-section magazine with output channels and sleeves for guiding the cartridge strip, a flexible element and a neck, divided into two channels for supplying two cartridge strips.

What is new is that the sections of the magazine are installed parallel to each other, between the first and second sections of the magazine there is a flexible element made in the form of upper and lower flexible arms, one ends of which are fastened to the receiving windows of the gun, and the other with vertically mounted necks, the upper and the lower parts of which are connected with the output channels of the first and second sections of the stores using flat curved guides, respectively. The second and third sections of the store are installed next to each other and are connected to each other by a curved guide.

The proposed technical solution is illustrated by graphic materials, where Fig. 1 shows a general view of the power supply system of an automatic gun, and Fig. 2 is a section along vertical necks.

The power supply system for an automatic gun consists of a magazine divided into three sections: 1, 2, 3. Each section of the magazine has outlet channels for the cartridge belt exit. Section 1, in which cartridges with BT shells are placed, is located in front of the fighting compartment. In section 1, an outlet channel 4 is made, which is connected to the guide 5. The guide 5, in turn, is connected to a vertical neck 6, to which is attached a flexible sleeve 7, located between sections 1 and 2. Section 3 of the store is connected via guide 8 to section 2, the output channel of which is connected to the guide 9 and through the vertical neck 10 with a flexible sleeve 11. Flexible hoses 7 and 11 are docked to the receiving window of the gun 12. In sections 2 and 3 there are cartridges with OFZ and OT shells.

The power system of the automatic gun works as follows. If firing is done with cartridges with BT shells, the cartridge belt 13 from section 1 through the outlet channel 4, the vertical neck 6 and through the flexible sleeve 7 is fed into the gun automation 12. When firing cartridges with OFZ and OT shells, the cartridge tape 14 from section 3 through the guide 8 , through section 2, the guide 9, the vertical neck 10 and the flexible sleeve 11 is fed into the automatics of the gun 12. Transfer of gun power from the tape 13 to the tape 14 is carried out by the gun feed switching mechanism.

Flexible hoses 7 and 11 provide the supply of cartridge tapes from the vertical necks 6 and 10 to the receiving windows of the gun at all angles of pumping of the weapon block along the guides, eliminating oncoming ledges and gaps. In addition, the sleeves allow you to shift the power system relative to the receiving windows of the gun, which facilitates the layout of the fighting compartment in the given dimensions.

Thus, the proposed technical solution allowed to reduce the length of the gun’s power paths, reduce the size of the power system and eliminate the possibility of failures in firing due to the fault of the power system.
