Description

The invention relates to the field of military equipment, and in particular, to combat vehicles with a rear location of the engine-transmission compartment having automatic loaders, ammunition, and a sealed fuel volume located in the inhabited compartment of the vehicle.

An analysis of the losses of military equipment in local conflicts showed that there is an urgent need to increase the security and survival of the crew, to increase the fire and explosion safety of combat vehicles when the ammunition and fuel are damaged by anti-tank weapons, and to ensure the operability of the loading machine during deformations of the vehicle’s bottom, for example, with a powerful mine explosion.

The main factors are determined, including those of a constructive nature, causing an explosion and fire during one or another form of damage. These include:

- destruction of fuel tanks from water hammer or explosion, fuel spraying when tanks are broken;

- fire ammunition as a result of shrapnel destruction or exposure to fire.

The damaging factors of anti-tank weapons include a stream of fragments moving along a cone with a vertex located in the center of the outlet on the back of the armor. The stream consists of fragments of the destroyed part of the shell of the ammunition or cumulative stream and a secondary stream of fragments from the elements of armor protection.

One of the directions for improving combat vehicles is to increase their security and fire and explosion safety. Until recently, the only way to prevent the ignition of fuel and ammunition, as well as the explosion of ammunition was the installation of powerful armor protection. However, its effectiveness is limited by the presence of structurally weakened zones and differentiation of the booking level, which leads to a certain probability of breaking through the armor of a combat vehicle.

Obviously, the mass of combat vehicles, in particular tanks, and the mass of their armor protection reached a reasonable limit. Therefore, increasing the security and survival of the crew, increasing the level of fire and explosion safety must be achieved due to other structural and layout solutions.

Fire and explosion safety of modern Abram and Leopard-2 tanks is ensured by isolating fuel and ammunition from the inhabited fighting compartment, vital units and equipment and placing them in armored compartments.

The fuel in the Abram tank is located in the engine-transmission compartment, in the bow of the hull behind the armored partitions (separating fuel from the inhabited compartment) and on the shelves outside the hull, the ammunition is in the tower niche behind the armored movable partition and inside the inhabited compartment, three crew members of the four are in the tower (Foreign Military Review, 1990, No. 2, "American Tank ML Abram and its modifications", http://www.pentagonus.ru/pubV68-1-0-754; Complete Encyclopedia of World Tanks. 1915-2000 Compiled by G.L.

The fuel in the Leopard-2 tank is located in the engine compartment and on the shelves outside the hull, the ammunition in the tower niche behind the armored movable partition and inside the inhabited compartment, three out of four crew members are in the tower (Complete Encyclopedia of World Tanks. 1915-2000 Compiled by G.L. Kholyavsky, Harvest LLC, Minsk, 1999, p. 362; http://warfront.ucoz.ru/Leo2/zLeo2shem.jpg).

The design and layout solutions used in the modern Western Abram and Leopard-2 tanks do not provide an acceptable level of crew protection and survival, fire and explosion safety, as three out of four crew members are in the tower, the probability of falling into which tends to increase, the fuel is separated from the crew by one armored partition, part of the ammunition is in the inhabited compartment, and part is behind the armored movable partition, which is opened by the loader when loading the gun during combat, those. in the time period when this ammunition tank can hit.

For the Abram and Leopard-2 tanks, it is typical that after breaking through the main armor of the tower there is a chance of destruction of the entire crew by secondary fragments, a fire in the inhabited compartment can lead to an explosion of part of the ammunition located in it, damage by anti-tank means of ammunition in the inhabited compartment leads to the explosion of ammunition. Moreover, in all cases, the survival rate of crews of combat vehicles is insufficient.

In addition, the Abram tank has unprotected fuel lines passing through the inhabited compartment, connecting the bow tanks to the rest of the fuel system. As practice has shown, damage to fuel tanks in the Abram’s reserved bow compartments with ammunition with a large residual armored effect leads to a fire and crew damage.

Known combat vehicle with a rear location of the engine compartment (see "Tank T-72A. Technical description and operating instructions", book 2, part 1. M .: Military publishing house, 1988, p.6, Fig. 3 ; p.23, fig. 13; p. 27, fig. 16, 17; p. 47, fig. 25; p. 107, fig. 50, 52, 53; p. 260, fig. 122), selected in as a prototype, containing habitable and engine-transmission compartments separated by a motor partition, in the first of which are the main armament with an ammunition consisting of shots from various types of shells located in the loading cassette, crew jobs, a sealed fuel volume, and in the second are the engine, power drive of the drive wheels and a device for transmitting torque from the engine to the power drive of the drive wheels.

In a combat vehicle with such an arrangement, the crew, fuel and ammunition are located in the same volume, two out of three crew members are in the tower. After breaking through the main armor of the tower, there is a chance of the destruction of the entire crew by secondary fragments. Damage to fuel tanks leads to a fire followed by an explosion of ammunition. The defeat of the elements of the ammunition leads to the subsequent explosion of the ammunition. Moreover, in all cases, the survival rate of the crew of the combat vehicle is insufficient. The disadvantage also includes the installation of a rotating conveyor of an automatic loader with an ammunition load on the bottom, which, when a powerful mine is blown up, is fraught with a failure of the automatic loader.

The technical result of the utility model is to increase the security and survival of the crew, increase the fire and explosion safety of the combat vehicle when the ammunition and fuel are damaged by anti-tank weapons, and also ensure the performance of the loading automatic machine when the bottom is deformed, for example, during mine detonation.

The technical result is achieved in that a combat vehicle with a rear engine-transmission compartment, for example, a tank containing inhabited and motor-transmission compartments separated by a motor partition, in the first of which are the main armament with an ammunition consisting of cassettes located in the automatic loading device shots with various types of shells, crew jobs, sealed fuel volume, and in the second are the engine, power drive of the drive wheels and a device for transmitting cr According to the utility model, the damping moment from the engine to the drive drive of the driving wheels is made in the form of a nose highly protected fire-explosion-proof control module and a weapon module, hermetically isolated from each other by an additional transverse partition, said motor and additional transverse partitions being made in such a way that certain sections of their middle parts are diametrically opposed relative to each other and to the central axis okru the information described around any cross-section of cartridges with ammunition shots of the main armament located in the armament module mounted on the pursuit of the tower of the combat vehicle, with a gap from the bottom, while the sealed fuel volume is separated from the crew’s workplaces by spaced sequentially arranged motor and additional transverse partitions, and from the weapon module by the motor partition.

The essence of the utility model is illustrated by drawings, where in Fig.1 shows a left view of a combat vehicle; figure 2 shows a cross-section. AA figure 1; figure 3 shows the remote element B of figure 1.

The combat vehicle contains a hull 1, including a roof 2 and a bottom 3, a motor partition 4, an automatic loader 5, a highly protected fire and explosion-proof control module 6, the main armament 7, an ammunition consisting of 8 shots 9 placed in the automatic loader 5, workstations 10 of the crew , sealed fuel volume 11, engine and transmission compartment 12, weapons module 13, hermetic additional transverse partition 14, running device 15.

The sealed fuel volume 11 is located in the engine-transmission compartment 12.

The proposed shape of the partitions 4 and 14 makes it possible to assemble the control module 6, the weapon module 13, and the engine and transmission compartment 12 in minimum volumes and providing the necessary gaps between the cartridges 8 and the partitions 4 and 14.

Improving the crew’s security is achieved by transferring crew’s workstations located in the tower to the highly protected bow module 6 of building 1, the protection mass of which can be increased by the amount of reduction in the tower’s defense mass due to a decrease in its dimensions and internal volume intended for crew workstations.

Improving the security and survival of the crew in module 6 is achieved by reducing the total area of the internal surfaces of the control module 6 (as compared with the inhabited compartment of the prototype) by introducing an additional transverse partition 14, which reduces the likelihood of crew damage in module 6 by secondary fragments.

Fire and explosion safety of module 6 and crew survivability are achieved by completely separating crew workstations 10 from the sealed fuel volume 11 by two spaced apart partitions 4 and 14, and separation from the ammunition set by partition 14.

In addition, the statistics of tank defeats in recent times show more and more hits in the tower, so the transfer of crew jobs from the tower to building 1, in this context, also helps to increase its survival.

The weapon module 13 is an armored full-swing platform with the main weapon 7, an automatic loading device 5, cartridges 8 with shots 9, mounted with the help of a running device 15 on the roof 2 of the body 1 of the combat vehicle and a multiplex information exchange channel connected to it.

The work is as follows.

If the sealed volume of fuel 11 is damaged, a local fire in the engine and transmission compartment 12 will not affect the ammunition separated from the fire by the partition 4 and the crew located at workplaces 10, separated from the fire by the spaced apart two partitions 4 and 14.

If the ammunition is damaged and it ignites, a local fire will not affect the sealed fuel volume 11, located behind the partition 4 and the crew, located at workplaces 10, located behind the partition 14.

With a mine detonation, the bottom 3 is deformed under the influence of a shock wave. Moreover, the introduction of an additional partition 14 creates additional structural rigidity of the entire bottom 3, which helps to reduce the deflection of the bottom 3 from shock loads, ensuring the deformation of the bottom 3, not exceeding the minimum clearance between the bottom 3 and the automatic loading device 5 in the weapon module 13.

The use of the utility model leads to increased security and survival of the crew, increase the level of fire and explosion safety of the combat vehicle.
