The claimed self-propelled mortar contains (as a design option) an armored 7/0 Body 1 mounted on a tracked chassis. Hatch 2 and embrasures are made on the hull (positions Z and 4, respectively). Inside hull 1, the motor-transmission compartment (position I), the front combat compartment (position II) and its rear combat compartment (position II) are located one after the other. The front combat compartment (position II) is separated from the motor-transmission compartment (position I) by partition 5, and from the rear combat compartment (position I) by partition 6. In the motor-transmission compartment (position I!) /5 Engine 7 is installed, with connected to the known rollers 8 is a crawler motor, which, in addition to the known rollers 8, also has support rollers 9 and a caterpillar 10. In the body 1 above the motor-transmission compartment (position I) there is a hatch for the mechanic-driver 11, which is closed by a cover 12. Above the front fighting compartment (position

I) a hatch closed by cover 13 is completed, and two hatches closed by covers 14 are made above the rear combat compartment (position III). In the aft part of the hull 1, at the corners of the latter, nodes 15 for turning the platform 16, made in the form of a sector of a circle with an apex, are installed at node 15. A mortar (IM position) is installed on the rotary platform 16, the lower node 17 of the barrel fastening 18, which is connected to a ball support similar to the one installed on the mortar support plate (IM position) of this design. On the basis of the platform 17, nodes 19 of the two-legged mortar 20 (IM position) are installed, to which the mortar barrel 18 (IM position) is attached. The sight 21 and the aiming mechanism 22 are attached to the barrel 18 of the mortar (position IM) and the bipod 20, respectively. Armor plates are attached to the sides of the rotary platform 16 (respectively, positions 23 and 24).

The sheet 23 is part of the side wall of the hull 1 between the walls 6 and the aft wall (position M) of the hull 1, and the wall t 24 is made of a shape curved with a radius K, which is equal to the length of the cutout in the side wall of the hull 1 (see fig. 4- 5). At the same time, a cutout 25 is made on the wall 24, located in front of the barrel 18 of the mortar (IM position) (see Fig. 1). The rotation of the platform 16 is carried out with the help of the rotation mechanism 26, fixed with one end to the floor 27 of the rear combat compartment (position II), and the other - to the rotary platform 16 (see Fig. 1 and Fig. 4). Fastening to the floor 27 and mortar equipment (position IM), located in the front combat compartment (position II) - similar to the above. Mines 28 (ammunition) for mortars (IM position) Ge are placed in both combat compartments of corps 1, respectively, in the front combat compartment (position I) and in the rear combat compartment (position II) (see fig. 1). On the upper part of the body 1, power units 29 of the suspension of the parachute system are additionally placed (see fig. 1-5). Observation of the outer space with closed lids 12, 13, 14 of the hatches on the body 1 is carried out through periscopic observation devices Z0 (see Fig. 1-5).

Other elements of the design of the self-propelled mortar installation, which do not relate to the essence of the useful model, in (Fig. 1-5 - are not shown. "

The movement of the self-propelled mortar is carried out with the help of a caterpillar drive, which consists of a caterpillar 10 and rollers 8 and 9, while the roller 8 is the driver. Seats of the mechanic-driver (position 11), gunner-operator and commander are equipped with periscopic observation devices 30 (see Fig. 1-5). ;" The self-propelled mortar is used as follows.

At the combat position, the covers of hatches 13 and 14, made in the roof of hull 1, are opened. The vehicle is turned along the azimuth to the direction of firing from mortars (position IM), located in the combat compartments of the ko (respectively, positions I and PI) (see Fig. 2 -3 and Fig. 5). The rotating platforms 16 with mortars installed on them (IM position) are turned relative to the turning nodes 15 and are extended beyond the dimensions of the side of the hull 1 and the vehicle (see Fig. 1 and Fig. 4). Crew members (not shown in Fig. 1-5) using sight 21

Ge" and the guidance mechanism 22 carry out the guidance of mortars (IM position) on the target, their subsequent loading with mines 5o 281 firing at the target (the process of loading and firing at the target is similar to 161). A change in the firing process of the azimuth aiming angle (see Fig. 4) (for mortars placed on rotary platforms 15 in the rear of the combat compartment - position II) is carried out by turning the platform 18 using the turning mechanism 26 (the range of aiming angles a is shown in Fig. 4).

After firing, the rotary platforms 16 with mortars placed on them (IM position) are turned in the opposite direction (also with the help of the turning mechanism 26) and moved into the housing 1 (see Fig. 2 and Fig. 5). At the same time, the side wall (position 23) of the rotary platform 16 coincides with the side of the body 1s in its plane. The barrels of all mortars (in combat compartments II and II) are set to the starting position and fixed, and the covers of hatches 13 and 14 above the combat compartments (respectively, positions I and II) are closed (see fig. 2-3 and fig. 5). At the end of firing, the self-propelled mortar installation, the design of which is claimed, is moved to another place (using a crawler).

If it is necessary to carry out a combat mission in the rear of the enemy, the self-propelled mortar can be delivered to the given area with the help of transport planes (position "LA" - see Fig. 6). For landing using a parachute system (position "PS" - see fig. 6), the latter is fixed in nodes 29, located on the body 1 of the vehicle, namely, on a self-propelled mortar installation (pos. "SMU" - see fig. 6).

Increasing the effectiveness of the application of the self-propelled mortar, which is claimed, is achieved by increasing the number of mortars that are installed on a vehicle, for example, on an armored personnel carrier converted to a self-propelled mortar, and the possibility of more accurate targeting of mortars with the help of a rotating platform, and the possibility of airborne landing .
