Description

The invention relates to military equipment, and more specifically to military vehicles, the armament of which consists of artillery guns and automatic small arms.

Known infantry fighting vehicle BMP-I (I), the main parts of which are the armored hull and turret, weapons, loading mechanism, engine and other systems. According to the arrangement of mechanisms and equipment, inside the machine is divided into a control compartment, into power, combat and airborne squads.

The fighting compartment is located in the middle of the vehicle. It includes a tower and part of the hull, limited by the partition of the power compartment, a rotating platform and the fence of the landing seat.

In the tower are installed:

- smoothbore gun;

- coaxial machine gun;

- gun loading mechanism.

The loading mechanism consists of two main parts: a conveyor and a shot feeding mechanism. The conveyor is designed to accommodate forty shots and automatically move them to the delivery line, from which the shot is captured by the feed mechanism. The conveyor is made circular and placed equidistantly rotating floor platform.

The method of filling the conveyor with shots includes the following operations:

- raise the levers of the loading mechanism;

- "rewind" the conveyor;

- fill the conveyor with manual shots.

The disadvantages of the infantry fighting vehicle and the method of filling the conveyor with shots are:

- small ammunition of smooth-bore artillery, as the conveyor capacity is limited by the transverse dimensions of the machine;

- long time filling the conveyor with shots, as this operation is carried out manually from the ammunition depot.

Known combat vehicle with a fighting compartment (2) and a method of loading shots into the conveyor of an automatic loader (3), which are selected as prototypes.

The fighting compartment of a combat vehicle contains an artillery gun, an automatic loader mounted on the floor of the fighting compartment, an annular conveyor in which shots for artillery guns are mounted vertically and mounted equidistant to the floor.

In parallel with the artillery gun, an automatic gun was installed with the possibility of vertical and horizontal guidance along with the gun. Inside the ring conveyor there is an equidistant floor with a magazine for placing cartridge belts of an automatic gun. The store is made in the form of a torus, divided into sections.

The known method of loading shots into the conveyor of a loading machine contains the following operations:

- turn off the weapon stabilizer;

- give the gun a maximum angle of descent;

- raise the nearest cell to the loading line;

- put a shot in the cell;

- lower the cell;

- turn the conveyor and raise another empty cell.

The disadvantage of a combat vehicle is the low capacity of the conveyor, limited by the transverse dimensions of the vehicle.

The disadvantage of the method of loading shots into the conveyor of the automatic loader after the ammunition is used up is the long loading time, since the operation of laying the shot into the cell is carried out manually.

The objective of the invention is to increase the effectiveness of the combat vehicle by increasing the ammunition load of artillery rounds and reducing the loading time of the conveyor shots after the ammunition is deployed, placed in the conveyor.

The problem is solved in that in the known design of a combat vehicle with a rotating conveyor containing a carrier and a fighting compartment, consisting of an armored hood with artillery guns and an automatic gun mounted in it, an automatic loader with a conveyor placed equidistantly to the floor of the fighting compartment, in which shots are vertically mounted for an artillery gun and a magazine for cartridge cartridges of an automatic cannon located inside an annular conveyor, an airborne compartment is located inside the carrier, in which th e conveyor feeding device shots. The make-up device is made in the form of a chain conveyor. Shots are vertically mounted in the links of the conveyor. The makeup device includes a drive and a unit for supplying shots to the conveyor containing a rammer, and the drive is kinematically connected to the feed sprocket of the conveyor and to the rammer of the unit for supplying shots to the conveyor.

The design of the combat vehicle implements a method of loading a rotating conveyor with shots, which includes turning the conveyor one step and stacking a shot in its cell. Before turning, the conveyor is fixed relative to the fighting compartment. Turn the fighting compartment to align the axis of the conveyor cell with the delivery line of the feed unit of the shots of the make-up device. The drive of the make-up device is turned on and the chain conveyor is moved until the axis of the shot, which is in the initial position with the delivery line of the feed unit, is aligned. The shot is sent using the feed unit to the conveyor cell and fix it in the cell. The rammer and chain conveyor are moved until the next shot and rammer in the starting position. Unlock the conveyor and rotate it one step until the cell axis aligns with the delivery line of the feed unit of the shots of the make-up device.

The installation of a device for feeding the conveyor with shots made in the form of a chain conveyor inside the landing compartment of the carrier increases the effectiveness of the combat vehicle, as its ammunition is increased. The use in the design of the drive recharge device kinematically connected to the conveyor feed sprocket and the shot supply unit to the conveyor reduces the loading time of the conveyor by shots.

The proposed solution is illustrated by graphic materials, where figure 1 shows a General view of the artillery support machine, top view;

figure 2 - layout of the conveyor and recharge device inside the artillery support machine.

The artillery support machine consists of a carrier 1 (Fig. 1) with an airborne compartment 2 and a fighting compartment 3 (Fig. 2). The composition of the fighting compartment 3 includes: an armored hood 4 (Figure 1), an artillery gun 5 and an automatic gun 6. On the floor of the fighting compartment there is an automatic loader 7 (figure 2) with a conveyor 8 in which shots 9 are vertically mounted.

Inside the conveyor 8, a magazine 10 for cartridge belts of the automatic gun 6 is placed (Fig. 1). In the landing compartment 2 mounted feed device of the conveyor 11 (figure 2). The make-up device 11 consists of a chain conveyor 12, the links of which are equipped with shots 9 and a drive 13, kinematically connected with the feed sprocket 14 and with the rammer 16 of the feed unit 15.

Machine artillery support works as follows.

The conveyor is rotated relative to the floor of the fighting compartment to align the axis of the shot with the plane of the axis of the barrel of the artillery gun. With the help of an automatic loader, the shot is sent to the chamber of the artillery gun and a shot is fired. In the indicated mode, firing is performed until the ammunition deployed in the conveyor is used up, after which the conveyor is fixed with a locking device relative to the fighting compartment. The fighting compartment, together with the conveyor, rotates until the axis of the cell of the conveyor is combined with the delivery line of the feed unit for the shots of the recharge device. In this position, the feed device drive is turned on and the chain conveyor moves until the axis of the shot, which is in the initial position with the feed line of the feed unit, is aligned. Using the feed unit, the shot is sent to the conveyor cell and fixed in it. With further movement of the chain conveyor, the rammer of the feed unit and the next shot come to their original position. The conveyor is unlocked relative to the fighting compartment and rotates one step until the cell axis aligns with the delivery line of the feed unit for the shots of the make-up device. The cycle of loading a shot into the conveyor is repeated until all cells of the conveyor are filled. Artillery firing is done after filling the conveyor with shots.

Shooting from an automatic gun is made by cartridges equipped in tapes and put into the store.

Thus, the proposed technical solution allowed to increase the efficiency of the combat vehicle and reduce the loading time of the conveyor shots.
