Famous combat vehicle [Pat. RF №2442097 C1, IPC F41H 7/00, application number2010128715 / 11, 07/09/2010, publ. 07/09/2010.], Containing the control compartment located in the bow of the machine, which houses the driver’s and crew member’s workplaces, the power compartment with the power plant and power transmission units housed in it with the systems serving them, the fighting compartment, including a tower and part of the hull behind the power compartment, an automatic gun with a machine gun paired with it, an anti-tank guided missile launcher (ATGM) are installed on the tower, and operator and commander workstations are equipped on the starboard side of the building, the ammunition depot for containers with ATGMs, and the airborne compartment located in the aft part of the vehicle and equipped with crew members' workplaces, while the combat vehicle is equipped with navigation equipment consisting of a periscope artillery compass and topographic orientation system (STO), intercoms providing external radio - and telephone communication, and an autonomous power unit, located in the machine body, in the control unit installed the STO heading indicator and the STO cartographer, on the roof An antenna of the satellite navigation system is fixed in front of the hatch in front of the crew member’s hatch, an all-round terrain viewing device is installed on the tower of the fighting compartment between the operator’s and commander’s hatches, the container ammunition with ATGMs is made in the form of longitudinally fixed trays, in the front part of which there are ribs, and in the back - covers articulated on the base of the trays and fixed with eccentric locks, providing a longitudinal compression of the containers to the front wall of the shell.

This combat vehicle also belongs to the class of tracked infantry fighting vehicles and infantry fighting vehicles with a two-seat fighting compartment. As part of an integrated orientation system, there are instruments that determine the azimuth, but the conditions of the combat compartment of the armored personnel carrier do not imply the placement of similar complex multifunctional systems.

Known drive azimuth device [US Pat. RF №2112201 C1, IPC F41H 5/20, F41G 5/14, application No. 95112138/02, 07/12/1995, publ. 05/27/1998.] Containing a bevel gear, a worm gear, a cardan shaft, a worm gear mounting bracket, while the worm gear is hinged on the bracket of the turntable, and to prevent the worm gear housing from rotating relative to the tower, there is a cardan protective casing made of two movable relative to each other parts pivotally connected to the housings of the bevel and worm gears, while the worm gear housing serves as the basis for fixing the guidance mechanism.

This drive is intended for use in tracked infantry fighting vehicles and infantry fighting vehicles, and the solution is aimed primarily at the interaction of the commander and gunner located directly in the fighting compartment.

As a prototype, a fighting compartment of an armored personnel carrier with stabilized cannon and machine gun weapons was selected, intended for use as part of the BTR-82A and BTR-82AM ["Unified fighting compartment with stabilized cannon and machine gun weapons" Operation manual 59104-9300010RE] with a gunner’s workstation, fire control system with controls and ammunition, including a turret that rotates in pursuit, and part of the hull.

The disadvantage of the combat compartment of the armored personnel carrier is the lack of the ability for the gunner to determine the position of the weapon in the horizontal direction, reference and indicate the angles of rotation of the combat compartment relative to the longitudinal axis of the armored personnel carrier.

The objective of the utility model was to increase the functionality of the gunner’s workplace, associated with increased coordination of crew actions and increased fire efficiency of armored personnel carriers, mainly with wheeled propellers.

The indicated task is solved by the fighting compartment of an armored personnel carrier with stabilized cannon and machine gun weapons, with a gunner’s workstation, a fire control system with controls and ammunition, including a turret turning in pursuit, and a part of the hull in which, according to the proposal, the gunner’s workstation is equipped with an azimuth device kinematically related to the epaulette.

The inventive utility model is illustrated by drawings.

In FIG. 1 presents a General view of the fighting compartment of the armored personnel carrier; in FIG. 2 - view of the interior of the fighting compartment from the gunner's place; in FIG. 3 is a kinematic diagram of an azimuthal device drive.

The fighting compartment of the armored personnel carrier contains a turret 1 mounted on the pursuit of 2 stabilized cannon-machine gun weapons, consisting of 30 mm guns 3 and 7.62 mm machine gun 4, with ammunition 5, gunner’s workstation (seat) 6, control elements 7 (not all shown ) fire control systems (in general, the fire control system includes a sight, two surveillance devices, a rotary and lifting mechanisms, a stabilizer, mechanisms for transmitting angles, reloading, lowering, fuse and changing the power supply). The gunner’s workplace is equipped with an azimuth device 8 kinematically connected by means of a cylindrical 9 and bevel 10 gears with shoulder strap 2. In this example, the azimuth device 8 is a pointer device with coarse and accurate reading scales and an armored personnel carrier contour applied to the protective glass.

In the process of performing a combat mission, the gunner located in the fighting compartment on the seat 6 controls the rotation of the tower 1, while the rotation from the overhead 2 is transmitted to the azimuth device 8 by means of gears 9 and 10, while the gunner has the ability to control the turret rotation angle by azimuth device (and respectively, the gun 3 and the machine gun 4) approximately (according to the relative position of the armored personnel carrier circuit on the protective glass of the device 8 and the large arrow, or precisely on the scales of the coarse (short arrow) and accurate (long arrow) countdown. In addition, when performing defensive tasks (when the armored personnel carrier is stationary) in poor visibility (at night or in difficult weather conditions), the use of azimuth indicators for predefined landmarks allows you to quickly target weapons and conduct effective obstructive fire.
