The utility model relates to armored vehicles, to military affairs [F41H7/00, B60F3/00, F41A23/24, F41H7/02].

The prior art includes the following: EMERGENCY RESCUE ARMORED VEHICLE [CN111765812 (A) - 2020-10-13].

Also known from the prior art is a BLOCK-TYPE TRACKED ARMORED VEHICLE [CN209371892 (U) - 2019-09-10], which pertains to the field of armored vehicles and, in particular, pertains to tracked armored vehicles. The armored vehicle consists of a load-bearing module, an action module, a power and control module, and an upper functional module.

Also known from the prior art is an ARMORED TANK [US2004183322 (A1) - 2004-09-23], having a combat module located on the roof of the vehicle hull, transported by a tracked drive. The interior of the hull is divided into three areas, namely the front area, in which the drive mechanism and the driver's seat are located, the rear area, in which the seats for the crew are located, and the middle area, which can be used for various purposes, depending on the layout of the tank, especially for placing an under-turret platform and/or at least one seat for the combat module operators and/or a place for storing ammunition and ammunition delivery mechanisms.

Implementation of a utility model.

The lightly armored transporter-tractor comprises a rectangular body having a triangular protruding front part, on the lower side of which shut-off plugs 1 and a wave-deflecting shield 2 are mounted, on the upper side of the protruding front part a transmission compartment hatch cover 3, a ventilation hatch cover 4 and an additional hydrodynamic shield 5 are mounted (Fig. 1). On the upper surface of the hull, starting from the front side, the commander's hatch cover 6 is mounted in the center, to the right of it the driver's hatch cover 7, behind the commander's hatch cover 6 an extension of the air intake pipe 8 is mounted, under which the engine compartment hatch cover 9 is mounted. Behind the engine compartment hatch cover 9 are the hatch covers of the troop compartment 10, to the side of which are mounted the filler neck covers 11, on the sides of the engine compartment hatch cover 9 are mounted the radiator guards 12. On the sides of the hull in the center are located the embrasure covers 13. At the same time, in the lower part of the hull, rectangular track niches are mounted, in which the aft hydraulic shields 14 are located in the rear part, in front of the radiator guards 12 above the track niches, water discharge pipes 15 are mounted, and in the front part of the track niches, side shields 16, tracks placed in track niches, stretched on support rollers 17. On the upper surface of the hull behind the hatch cover of the engine compartment 9, above the hatches of the landing compartment 10, a protective box 24 with an opening is mounted. Under the protective box there is a ring for installing the turret 18, in the center of which there is an opening for installing the turret 19. In this case, the ring for installing the turret 18 is mounted on the body of the transporter-tractor under the protective box 24. Along the edge of the ring for installing the turret 18 there is a flange 20. A turret module 21 (Fig. 2) is mounted in the opening for installing the turret 19 on the flange 20, which contains the turret 22 and the drum with ammunition 23. The turret module is mounted in such a way that the junction of the turret module 21 with the body of the transporter-tractor (including the ring for installing the turret 18 and the flange 20) are located under the protective box 24. The protective box 24 is made in the shape of a polygon (in the embodiment, a nonagon), while from the front part of the protective box 24 the faces of the polygon are made in such a way as to form a wedge-shaped shape, tapering toward the front vertex of the polygon. The configuration of the faces on the sides of the tower 22 is implemented in a similar manner (from the side parts of the protective box 24, the faces of the polygon are made in such a way as to form a wedge-shaped shape, tapering toward the side vertex of the polygon).

All joints between the polygon faces are additionally welded. The protective box 24 is made of steel. In the embodiment, the protective box 24 is made of armor steel with a thickness of 5 to 130 mm (for example, ARMSTAL 450).

The utility model is used as follows.

Before installation, the area under the turret mounting ring 18 is leveled (Fig. 3). Then, the turret mounting ring 18 is mounted above the engine compartment hatch cover 9, above the troop compartment hatch covers 10, and an opening for installing the turret module 19 is formed in the center of the turret mounting ring 18. After that, an iron strip 12 mm thick and 150 mm high is welded along the entire perimeter of the opening for installing the turret module 19, thus forming the side 20. Then, the protective box 24 is mounted on top of the hull by means of a welded joint. Then, the turret module 21 is installed in the opening for installing the turret module 19. The final assembly consists of connecting the turret 22 to the electrical system and connecting the ammunition drum 23 to the turret 22. The operability is checked by firing at the range.

During operation of the product, the turret box 24 protects the junction of the turret and the hull from both targeted impacts (for example, a potential enemy) and from accidental mechanical impacts during operation of the product.

The declared technical result - increased protection of the junction of the turret module and the hull of the light armored transporter-tractor, is achieved due to the fact that at the place of installation of the turret 22 to the hull, a protective box 24 is mounted, which covers the junction of the turret mounting rings 18 and the side 20 of the junction of the turret module and the hull of the light armored transporter-tractor. Due to the specified shape of the protective box 24, in particular, protection is provided from the impact of weapons of destruction of a potential enemy when shooting from the front and sides (due to the wedge-shaped box from the front and sides - when bullets hit, they ricochet without the possibility of penetrating the protective box 4). Also, the protective box 24 protects the junction of the hull with the turret 22 from accidental mechanical impacts during operation (taking the impact on itself), and also provides additional protection from precipitation. All joints between the faces of the polygon are additionally welded to increase the reliability of the connection of the faces of the protective box 24 to each other.

In the embodiment, the protective box 24 can be made of armor steel with a thickness of 5 to 130 mm. The specified thickness range (from 5 to 25 mm) is guaranteed to provide bulletproof protection (from 25 mm to 130 mm) and projectile-proof protection. The specified values were measured experimentally using the ARMSTAL 450 brand. Different thickness values can be selected depending on the planned operating conditions (weapons of destruction of the potential enemy).

An example of achieving the stated technical result.

To confirm the declared technical result, experiments were conducted on several types of products.

The first type is according to the declared decision.

The second type is according to the tumbled solution, but without using the wedge-shaped form of the edges on the front side and on the sides.

The third type is according to the prototype solution.

For the first and second types, protective boxes 24 with the same thickness of 20 mm were used.

The tests were conducted as follows: fire and mechanical impacts were applied to the transporter-tractor at the point where the turret 22 was attached to the hull. One cycle of impact included shooting at the specified location from automatic small arms from the front and sides, as well as simulating the impact of atmospheric precipitation on the product and mechanical impacts. The number of identical cycles that the product withstood while maintaining full operability of the turret element was calculated as a protection criterion. The following results were obtained during the experiments:

first type - 35 cycles;

the second type - 21 cycles;

the third type - 9 cycles.

Thus, the declared technical result is confirmed. And the possibility of achieving the declared technical result by means of the specified set of essential features is also confirmed.

The declared technical solution is a single product, it can be manufactured at the manufacturing plant by means of assembly operations. All functional elements important for achieving the declared technical result are connected to each other mechanically.
