Description

Stand for working out a pre-loaded automatic machine gun for loading a tank gun.

The utility model relates to equipment for developing the design of mechanisms and machines, and can be used in the study and development of kinematic links, movement dynamics and design of the main components of the designed weapons systems, and in particular, a reckoned automatic loader (A3) tank gun.

A variety of ammunition supply and loading systems are known, including automatic gun loading mechanisms in the turret of an armored vehicle, for example, a tank.

In the T-72 tanks (see the book "Modern Tanks edited by B. Safonov and V. Murakhovsky, Moscow, Arsenal-Press, 1995, p. 115), which were produced in Russia and other countries and are in service with many armies of the world, the A3 is used, in which a mechanized combat unit in a rotating conveyor with trays is located around the perimeter of the fighting compartment under the cockpit floor. In each tray, the projectile is placed horizontally with its head towards the axis of rotation, the propelling charge in the partially burning sleeve is under the shell of the shell with a metal tray (non-burning part of the sleeve) from the axis of rotation. Automatic loading is carried out from a mechanized warhead by removing the projectile and charge into the loading plane, raising them to the sending line and moving them into the charging chamber with a reloading chamber. The shell tray after a shot at the next loading of the gun is automatically thrown out through a special hatch in the roof of the tower.

A serious drawback of this A3 is the placement of charges around the circumference in the fighting compartment, which increases the likelihood of enemy shells falling into them when fired from all sides in a 360 ° projection, and when the ammunition explodes, it leads to the death of the crew and the permanent loss of the vehicle.

F41A9

In the main tank-producing countries, there is a tendency: to increase the safety of crews and the survivability of vehicles, in the designs of promising tanks, provide for the removal of the ammunition in a mechanized combat station located in an armored compartment behind the turret. In this case, the loading of the gun is done either manually, as on the American M-1 Abram tank (see the same source, p. 136), or using the loading mechanism.

Known automatic loading mechanism of the gun according to the patent of the Russian Federation No. 2195617, MKI F41A9 / 38, which includes a magazine, a conveyor belt, a conveyor rotation drive, cartridges for transporting a shot, a shot retention mechanism, a receiving tray, conveyor stopper drive mechanisms, cartridge opening and retraction.

The mechanism is made in the form of an autonomous removable transport-loading container (FEC), consisting of an armored body formed by a roof and a lower wall, side right and left walls, as well as front and rear walls welded together. The fuel and energy complex is removably mounted on the rear wall of the tower, in which the entrance hatch is made to move the shot from the conveyor through a window made in the front wall on the loading line.

The well-known automatic loading mechanism is complex in design, very high demands are placed on it for reliability and safety, and the armored case of his store, closed on all sides, does not allow for the development of kinematics, dynamics and design of the main elements, and even more so, of promising weapons systems being developed . In addition, it is difficult to adapt to the use of various types of ammunition and mechanized ammunition, designed for a different number of shots.

This useful model solves the problem of developing the design of a turret tank gun automatic loader by creating a stand that functionally simulates a loading cycle.

The problem is solved in that the stand is equipped with a supporting table, on which the fuel dispenser and the breech of the tank gun with a charging chamber and a shutter are mounted, mounted relative to each other in accordance with their installation on the tank, the fuel dispenser is formed by the front and rear walls connected along the upper and lower the ends with longitudinal ribs in a rigid frame open from above and from the sides, and in the lower part along the longitudinal axis - with a box-shaped receiving tray and a guide chute, forming a base, symmetrically relative to the the axis of the axis is a system of holes, windows and bores for installing the shafts of the conveyor rotation mechanism, while the conveyor is arranged to accommodate a variable number of cartridges with shots and change the center distance between the shafts of the rotation mechanism, and the stand is equipped with a control system and electric equipment A3 with remote control each of the operations of the charging cycle separately, and with ensuring the sequence of operations of the cycle in all modes.

The nodes of the control system and electrical equipment A3 are included in the stand scheme with the possibility of performing such cycle operations as, for example, changing the conveyor rotation speed, stopping and rigidly fixing the conveyor with the selected viewer in the loading plane, trapping a shot in the receiving tray and sending a shot at various angles loading.

The structural elements of the stand are equipped with a system of sensors and limit switches, and the fuel and oil complex is made with the possibility of visual monitoring and fixing photo and video equipment of the kinematic links A3 with the recording of parameter values in real time.

The conveyor is made with the possibility of placing shots in it, alternately, in an amount from the minimum sold in the Leopard-2 tank store to the maximum exceeding that realized in the mechanized installation of modern Leclerc, T-90 and T-80 tanks, with a total number of 14 to 32.

Analysis of the main distinguishing features showed:

that the TZK is formed by the front and rear walls connected by longitudinal ribs on the upper and lower ends to a rigid frame open from above and from the sides, and in the lower part along the longitudinal axis - a box receiving tray and a guiding groove, forming a base, makes it possible to work out the design A3, to optimize the speed of rotation of the conveyor, to determine the moment of switching on its stop with the selected shot in the plane of delivery, to work out the process of reliable and reliable collection of shots in the receiving tray, to work out sent e in the bolt shot gun as the remotely (determine loading rod release distance) and for security-speed operation;

-performing the system of holes and bores in the front and rear walls of the TZK store made it possible to install the conveyor rotation shafts at different center distances and set the conveyor with a variable number of shots, which allows the use of TZK in versions for military vehicles with their fighting compartment and the corresponding number of vyutrels;

- the execution of the conveyor with the possibility of placing shots with a total number of 14 to 32 allowed the development of the reckoned A3 with ensuring the ammunition level at and higher than that of the best modern tanks, such as Leopard-2, Leclerc, T-90 and T-80 ;

- placement on the stand of a system of sensors and limit switches, photo and video equipment, made it possible to combine video recording of the work of kinematic links A3 with recording the parameter values in real time and work out an optimal loading cycle in time.
