Description

The invention relates to military equipment, namely, to the designs of the combat departments (BO) of combat vehicles of the ground forces of the light weight category.

The BMP-1 infantry fighting vehicle is known (BMP-1 infantry fighting vehicle. Technical description. Military publishing house of the USSR Ministry of Defense, Moscow, 1972, p. 14), which has a BO located in the middle of the vehicle’s body between the partition of the power compartment and fencing landing seats. BO includes a single combat module, consisting of an armored cap with a hanging basket. In the armored cap installed:

- smoothbore gun of caliber 73 mm;

- coaxial machine gun;

- gun loading mechanism;

- sight;

- control equipment;

- guidance drives;

- observation devices;

- operator's hatch;

- hatch issuing shots.

On the floor of the hanging basket are installed:

- mechanized stacking of 40 high-explosive fragmentation (HE) rounds;

- gunner seat with remote control;

- cartridge case with magazine for coaxial machine gun;

- styling for two shots.

An arm for anti-tank guided missiles (ATGM) is mounted on the barrel and armor mask of the gun. To point the gun, coaxial machine gun and ATGM into the target, a periscopic combined sight and mechanisms for raising the gun and turning the turret are installed in the combat module.

The disadvantages of the combat module are:

1. Impossibility of shooting at once and low accuracy of shooting at night.

2. Low rate of fire.

3. The impossibility of "tandem" firing ATGM.

4. The inability to automatically aim the line of sight of the sight.

Known launcher (PU) (Patent RU No. 2316708 of 02/10/2008, IPC F41A 23/42), which contains a launch bracket with a PTURS guide kinematically connected through a lever with a drive screw mounted on a launch bracket. The guide is equipped with a combined armored screen, the upper part of which is made of a heat-reflecting thin sheet, and the side is made of armored plate.

The disadvantage of PU is the large moment of inertia of the swinging part, consisting of a guide and a drive, due to the articulation of the drive with the start bracket. As a result, when the combat vehicle moves over rough terrain, the stabilizer's performance deteriorates due to the inertial sway of the guide.

A well-known weapon system of a combat vehicle (Patent RU No. 2360208, IPC F41H 7/02, F41A 27/30), comprising a coaxial small-caliber automatic cannon (AP) and a machine gun mounted in the fighting compartment, a launcher with ATGM, and a fire control system including an aim gunner and weapon stabilizer with a tele-thermal imaging automat for tracking objects (ASOTT), a control unit (BU), a gunner’s console, a ballistic computer (BV) with an input information sensor system and an automation unit. The gunner’s sight is combined, it includes a video viewing device, a stabilization and pointing unit for the head mirror, a module block, a control panel for the thermal imager and a power supply.

The disadvantages of the armament complex of a combat vehicle are the need for its maintenance by two crew members (commander and gunner) and the inability to conduct targeted fire from AP and machine gun in the absence of power supply on board the vehicle.

The objective of the invention is the creation of a single-seat combat module with enhanced combat capabilities, the work of which is provided by one crew member (gunner), improving the work of the weapon stabilizer and increasing the accuracy of firing AP and machine gun.

The task is solved by a combat module, consisting of an armored cap with a hanging basket with an armament complex placed in them, including an automatic cannon paired with a machine gun, mounted in a rotating mask, AP and machine gun ammunition, PU ATGM, combined gunner’s sight, and weapon stabilizer. What is new is that to ensure that the combat module is serviced only by a gunner, a rotating mask is kinematically connected through an additional lever system to an additionally introduced optical sight-backup mounted on the left side of the armor cap, the ATGM launcher is located on the right side of the armor cap, the PU drive is rigidly mounted on starting bracket, the drive screw through an articulated earring is connected to the lever of the guide, and in the aft part of the armor cap is installed th fire in the wind sensor control system.

The proposed technical solution is illustrated by graphic materials, where in FIG. 1 shows a general view of a single-seat combat module, in FIG. 2 is a top view of the combat module, in FIG. 3 is a front view of the combat module, in FIG. 4 shows the kinematic connection of a rotating mask with a backup sight, in FIG. 5 - drive PU.

Single combat module consists of an armored cap 1 and a hanging basket 2. A rotating mask 3 is mounted on the armored cap 1, in which an automatic gun (AP) 4 and a machine gun are fixed 5. To the right of the AP is a magazine 7 on the floor 6 with ammunition for 100 rounds with armor-piercing tracer shells and a magazine 8 with 200 rounds of ammunition with high-explosive fragmentation shells. Right on the side surface of the armored cap 1 is fixed PU ATGM 9. PU are self-contained unit that provides the placement of two ATGMs in transport-launch containers. PU provide vertical guidance of the ATGM and their subsequent launch. The design of the launcher allows for “tandem” firing of ATGM systems.

PU PTURS consists of a starting bracket 10 with a guide 11 kinematically connected through an earring 12 with a screw 13 of the drive 14. On the armored cap in front of the gunner is a combined gunner’s sight 15. The sight includes a stabilization and guidance unit for the head mirror, electrically connected to the rotary position sensor masks 3, module block, power supply, video viewing device and control panel of the thermal imager. The gunner’s combined sight is designed for:

- a survey of the terrain, detection and identification of the target at any time of the day;

- stabilization in two planes of the field of view, guidance and retention of the aiming mark on the target by signals from the gunner’s control panel and ASOTT from the spot and when the machine is moving;

- measuring range with a laser rangefinder;

- the formation of the control field to ensure firing ATGM;

- aiming when firing all types of ammunition day and night.

To ensure targeted firing from the AP and machine gun at ground and air targets in the combat module, an optical doubler sight 16 is provided, the pivoting head of which is connected to the rotating mask 3 through a system of rods and levers. The AP and the machine gun are aimed at the target using horizontal and manual drives vertical guidance, while the gunner observes the target through the eyepiece 17. This provides the possibility of targeted firing from the AP and machine gun in the absence of power on board the machine.

Right on the roof of the armored cap 1 is placed PU SPZ 18, designed to launch smoke grenades to camouflage a combat vehicle.

In the aft part of the armor cap 1 is installed a wind sensor 19, designed to measure the transverse relative to the direction of fire component of the wind speed. Information about the measured speed is sent to the ballistic computer of the fire control system to work out corrections for the influence of wind.

Thus, the proposed technical solution made it possible to create a single-seat combat module with enhanced combat capabilities, the work of which is provided by one crew member (gunner), improve the work of the weapon stabilizer and increase the accuracy of AP and machine gun firing. The technical solution is implemented in the design of the upgraded combat vehicle BMD-2.
