Description

The invention relates to the field of military equipment, specifically to objects of armored vehicles.

Known self-propelled howitzer self-propelled guns Msta-S. The armored hull of the self-propelled guns is similar in design and geometry to the hull of the T-72 tank, the lower part of the hull using torsion shafts and balancers from the T-80 tank in suspension. The engine, transmission, control drives and suspension are mounted in the housing. The chassis of the self-propelled guns is similar to the tank (T-80) and consists (for one side) of six road wheels, a guide wheel with a track tension mechanism, a drive wheel with removable gear crowns and five support rollers. The suspension is independent with long torsions, which is why the corresponding rollers of the right and left sides are not coaxial (the rollers of the left side are shifted forward by 110 mm). The tower is welded from rolled armor plates. It contains: a 2A64 howitzer with a guidance and aiming system, an automated projectile feeding and storage system. The ammunition is located in the tower. It consists of 50 rounds of 152 mm caliber.

(see Katorin Yu.F. Everything about tanks. M: Polygon; AST, 2011, http://www.arms-expo.ru/049050053052124049051053050.html).

The main disadvantage of the known installation is that it has huge dimensions; also the weak armor of the Msta-S self-propelled guns make it awkward, clearly visible during close combat. When aiming the howitzer on the target, it is necessary to rotate the tower relative to the hull. Therefore, its main purpose is the destruction of tactical nuclear weapons of tanks and other armored vehicles at a certain distance. In cities with narrow streets, in mountainous conditions, this prototype with its long barrel will be very difficult to move around.

The closest technical solution to the proposed invention is the Streetsvagen tank, in which the gun is rigidly connected to the tank body. When turning the gun in one direction or another, the enemy must turn the entire tank. The change in the angle of the gun’s guidance depends on the change in the length of the hydropneumatic cylinders connected to the rollers of the tank. The armored hull is welded, inside it is divided into three compartments: the power - in the bow, the combat - in the middle and the auxiliary - in the rear of the car. Armament: the main weapon of serial tanks is a rifled 105-mm gun L74, rigidly fixed to the base of the machine body, with an automatic loading mechanism. The immobility of the gun allowed the use of a simple and reliable automatic loader, which ensured a rate of fire up to 15 rounds per minute. Rebooting the automatic loader is done manually through two aft hatches and takes 10 minutes. The standard ammunition is 50 rounds. As an additional weapon, three 7.62 mm machine guns were installed on the tank. Chassis: the chassis of the tank consists of a hydropneumatic suspension, metal tracks, four road wheels (on the side) and front-wheel drive wheels. At the same time, the controlled suspension makes it possible to widely vary the inclination of the hull in the longitudinal plane, and hence the angle of the gun’s pointing (see Katorin Yu.F. Everything about tanks. M: Polygon; AST, 2011, http: // www. sa100.ru/armor/Swe/strv/strv103.php).

The main disadvantage of this prototype is the inability to fire immediately. It can’t use powerful mortar shelling of the target, it takes a lot of time to replenish ammunition, if the frontal part of the hull is damaged, it cannot be changed in the field, which makes it incapable. And also in cramped conditions (in the mountains, in narrow streets) with a horizontal arrangement of a long trunk, inconvenience occurs.

The objective of the present invention is to increase firepower due to the main weapons, replacing additional weapons depending on the situation of the fighting, the ability is on the battlefield for as long as possible, making it more maneuverable and creating devastating blows to the enemy.

This object is achieved by the fact that in a self-propelled mortar installation, comprising a one-piece housing, including six track rollers, a guide wheel with a track tension mechanism, a drive wheel, five supporting rollers, a motor compartment in the rear of the hull, the main armament is installed on top of the solid body, consisting of of two mortar barrels capable of changing target angles in the range of 45 ° -100 ° in three planes using four pneumatic cylinders, two for each barrel, moving along the rods, allowing you to change the length of mortar barrels using electric motors, with a removable frontal panel mounted on the front with the ability to open, and if necessary replace it with a new one, and additional armament consisting of a machine gun or grenade launcher or flamethrower is installed on the frontal removable panel with a slope in front , or an automatic aircraft gun, with the possibility of replacing additional weapons depending on the combat situation.

The proposed design of a self-propelled mortar installation makes it possible to install two mortar barrels of large diameter, changing the angles of aiming at the target; lengthen mortar barrels for firing range; the installation of additional weapons on the front panel, depending on the combat situation; rapid replenishment of ammunition of the combat vehicle, and if the frontal part is damaged, replacing it in the field to continue the battle, making the tank more maneuverable on city streets, in mountainous conditions, surpassing other tanks to fire on mountain tops, or high-rise buildings, etc.

The invention is illustrated by drawings, where:

- figure 1 shows a self-propelled mortar installation (SMU), a General view in a perspective view;

- figure 2 is the same side view and top view, both in section;

- figure 3 - mortar trunks on top of the housing;

- figure 4 - the upper sections of the mounting barrel of the mortar;

- figure 5 - fastening the lower part of the trunk to the bottom of the SMU;

- 6 - SMU, side view, front view, top view;

- Fig.7 - mounting of the removable panel to the top of the housing;

- Fig. 8 is a front panel raising mechanism;

- Fig.9 - extension of mortar barrels.

SMU represents a single body with a large angle of inclination of the front panel in front, which can be lifted and also removed from the machine body (Fig. 1). The crew (figure 2) can consist of three people - A driver, located in front of the hull and to the left of the longitudinal axis of the self-propelled mortar. In the front of the hull to the right of the longitudinal axis is the position of gunner B. Closer to the aft of the longitudinal axis to the right was crew commander B. At the top of the hull (Fig. 3) two mortar barrels 1 (200-250 mm) are installed, capable of being extended, increasing in length for the firing range (Fig.9). You can use the installation of retractable barrels, when extended which appear different diameters, if this does not affect the shot of the projectile (see Patent No. 2178135, IPC F41A 21/00, 2002). The angle of inclination of the trunks - 45 °, the rise - up to 100 ° relative to the longitudinal axis of the body of the SMU. Perhaps the installation of changing the angles may be different, depending on the design. Trunks 1 can be aimed at the target, both in the frontal and in the sagittal planes. They are freely enclosed in annular joints 2 (Fig. 4) and connected to pneumatic retractable cylinders 3, capable of moving annular joints with trunks freely sliding along rods 4, due to which the angles of guidance of the trunks change. Between each barrel rubberized covers 5 (figure 3). The lower part (figure 5) of the barrel 1 is connected by a fastening 6 to a platform 7 standing on a spring suspension 8, connected to the bottom of the SMU 9. Other connections to the bottom of the SMU are allowed. The barrels are charged in their lower sections, through the side bolt 10. The barrels can end openly at the bottom of the self-propelled mortar installation, so that all powder gases are removed under the bottom of the machine without creating gas contamination inside the SMU. When firing shells, powder gases are emitted under the bottom of the self-propelled gun, where the return from firing will be created. Therefore, on SMU it is possible to install mortar retractable barrels of a larger diameter, because they will not create a noticeable return to the whole body. It is also possible to replace the removable mortar barrels 1 in oval rings connected by pneumatic cylinders 2, for example, during the development of a resource. The work of aiming the barrels at the target can be carried out both automatically through the fire control complex, and manually controlled by the gunner or crew commander. Mortar shelling at a target can be carried out simultaneously from two barrels or separately at different angles from each other.

On the front part (Fig. 6) of the housing there is a front removable panel 11, which can be lifted up by the extending lifts 12, which are pneumatic extension cylinders fastened to the panel by removable devices 13 in the form of pins that can be removed manually to prepare the panel for removal from the car body. At the top of the case, where the upper part of the removable panel is connected, there are also removable pins 14 (Fig. 7), when they are removed, the panel is ready to be removed from the case. Option II is possible: the panel 11 (Fig. 8) can be raised and lowered using cables 15 attached to the hooks 16 located along the edges of the panel through the supporting lifting brackets 17. Thereby, the cables are wound on the rotating rollers 18 located on each side of the aft body parts. The rollers 18 can rotate from the engine idling. Using a truck crane or other equipment, it is possible to install a new panel on the front of the case. With the front panel raised, the SMU can be loaded quickly with ammunition, in addition, visibility improves when driving in non-hazardous terrain. If the front panel 11 is damaged, it can be replaced in the field. On the front panel 11 (Fig.6) in the loophole 19 can be installed additional weapons 20 for direct-fire combat (automatic gun, grenade launcher, flamethrower, etc.). In addition there is a hatch 21 with observation devices; for the driver-mechanic nearby, the possible installation of a machine gun is 7.62 mm. At the top of the body of the self-propelled mortar installation, to the right of the right barrel, there is a commander’s turret with observation devices and a hatch 22. On the commander’s self-propelled mortar installations, radar retractable installations 23 can be installed, this could help in detecting the enemy and give orders to batteries of self-propelled mortar installations for firing, if cars are hidden in deep trenches.

With the front panel raised, the SMU can be loaded quickly with ammunition, and visibility is also improved when driving in non-hazardous terrain. If the front panel is damaged, you can replace it in the field.

The present invention is a fundamentally different layout from other combat vehicles, carrying powerful weapons capable of delivering crushing blows that exceed the power of modern tanks and self-propelled artillery. Also has the ability to quickly reload shells when lifting the front frontal panel. Thanks to the proposed layout of weapons, this design is made more maneuverable on various landscapes of the earth.
