Description

The invention relates to the protection of armored combat vehicles from destruction and can be used to destroy incoming ammunition for military equipment. Progress in improving weapons against armored vehicles, such as the Javelin and the Israeli Spike-LR/-2, requires the creation of new devices to protect armored vehicles. If the enemy has developed reconnaissance and strike contours, the lack of protection from detection leads to additional unjustified risks. The proposed “Device of lightweight roof mesh screens with built-in dynamic protection” significantly reduces the risks and threats to military equipment of the ground forces, has two orders of magnitude lower cost in comparison with known analogues and the prototype, and in the conditions of the air defense system contributes to the rapid and widespread equipment of everything involved in the air defense system equipment with EDZ sets and will contribute to the implementation of assigned tasks.

An analogue to the proposed one is a device for protecting armored vehicles according to RF patent No. 3324138 dated 07/06/2006 “Method and device for protecting armored vehicles.” The invention relates to the field of weapons, more specifically to the protection of armored vehicles (BTT) from aiming and guidance systems of anti-tank weapons (ATW). The method consists in setting up several camouflage aerosol curtains with one device by ejecting an aerosol of forming burning elements from the body of a grenade thrown in the direction of the threat. The curtain closest to the object of protection is created from smoke-generating segments that have masking properties in the visible and infrared (IR) wavelength ranges of the spectrum. Subsequent curtains are made of smoke-forming and dipole materials to simultaneously camouflage an object and create false targets that are effective in the IR and radar (RL) wavelength ranges. The device contains mortars loaded with grenades in the form of a cylindrical glass with pyrotechnic aerosol-forming equipment, propelling and ignition-explosive charges. The grenade body is made of two metal sections rigidly connected by adapters. The invention makes it possible to increase the total time of effective operation of aerosol curtains and protect armored vehicles from anti-tank weapons not only ground-based, but also air-based (helicopters and airplanes).

This method requires constant monitoring of the environment and timely detection of the launch of MANPADS or the approach of loitering ammunition to the upper surface of military equipment. In the case of counteraction to Israeli Spike-LR/-2 anti-tank missiles, the situation is even more unfavorable for our armored vehicles.

There is a known analogue developed by the state. by the Rostec Corporation, a means for protecting armored vehicles, which the Russian army adopted for service in 2021. The Military Review magazine published an article: “The ZVD35 optical-electronic countermeasures ammunition has been adopted by the Russian army.” The 3VD35 ammunition is designed to protect the upper hemisphere of equipment from attacks by high-precision weapons, including Javelin anti-tank missile systems. The ammunition is fired when a threat arises. The 3VD35 is fired, creating a cloud of aerosol interference that disrupts the guidance of enemy projectiles. In the absence of electronic warfare, the ammunition is capable of protecting the upper hemisphere of the vehicle, which is made of thinner sheets of armor from weapons with laser, thermal and optical guidance systems. The 76 mm caliber ammunition was developed at the Central Research Institute of Precision Engineering (TsNIITochmash).

The weight of 3VD35 is 1.8 kilograms. This device is susceptible to electronic warfare. To calculate the exact, down to mm seconds, shooting time, constant monitoring of the azimuth and elevation angle of the approach of loitering or ATGM ammunition is required.

The prototype for the proposed invention is the Arena-E vehicle self-defense system according to RF patent No. 2102678, F41A 23/00, publ. 01/20/98, Design Bureau of Mechanical Engineering. The design of the ammunition is described in RF patent No. 2127861 of the same company.

In the prototype, for targeted destruction of enemy missiles and grenades, narrowly targeted protective ammunition is used, which has a high-speed response and is placed along the perimeter of the tank turret in special installation shafts.

The sequence of operation of the Arena-E complex is as follows:

- after turning on the radar, the search for targets approaching the tank is carried out automatically;

- then the station is switched to auto-tracking mode, generating target movement parameters and transmitting them to the computer, which selects the number of protective ammunition and the time of its operation;

- defensive ammunition forms a beam of destructive elements that destroy the target as it approaches the tank.

One of the disadvantages of the known KAZ is the following:

In the process of destroying the target, at a height of (5-20) m, the protective ammunition and the approaching projectile are detonated, with the formation of explosion products, which are unmasking signs for the tank, increasing the likelihood of its detection and destruction by other enemy anti-tank weapons (PTS).

In the context of the massive use of modern ground and air anti-tank weapons in the context of deployed combat operations and wars, equipping military equipment with the Arena complex is not enough.

A simpler and many times more reliable method and device for protecting military equipment is required. The use of the Arena complex requires constant monitoring of the environment and timely detection of the launch of ammunition and its approach to the upper surface of military equipment. In the case of counteraction to Israeli Spike-LR/-2 anti-tank missiles, the situation is even more unfavorable for our armored vehicles.

The difficult-to-manufacture components of the ArenaM complex do not allow them to be used en masse to protect military equipment currently operating in the SVO operation. The cost of one set of Arena devices does not allow us to begin its mass production. Its use has currently been announced on T-14 Armata tanks and partially on T-90 tanks.

Shielding a tank with an aerosol curtain and anti-charges from ammunition attacking from the upper hemisphere requires accurate determination of the launch time of the damaging ammunition. Experiments confirm the difficulty of creating a single shielding formation in the air with the required lifetime. The Arena device kit will not be able to fully protect the upper hemisphere of military equipment, which is subject to constant attack by ammunition while overcoming the front line of defense.

The enemy's massive use of conventional dummy rockets launched in the direction of attacking armored vehicles will cause the rapid consumption of aerosol ammunition and interceptor ammunition. Ultimately, such a development of events will leave armored vehicles defenseless against really damaging precision-guided ammunition.

The purpose of the invention is to create a reliable, inexpensive, requiring minimal manufacturing costs, a device for self-defense of armored vehicles against roof-mounted ammunition, ensuring rapid implementation and subsequent repair and equipping of spent, built-in warheads and their maintenance in remand battalions stationed in front-line combat areas.

The proposed technical solution is based on the physical ability to move explosive charges using mesh frame assemblies filled with rods, in the crosshairs of which dynamic explosive charges are built in at a safe distance from the armor. The problem is solved as follows.

In FIG. Figure 1 shows the placement of explosive charges, instantaneous detonator capsules inside the explosive charge, in the crosshairs of a conventional welding joint, and a mesh frame mesh. In FIG. Figure 2 shows the assembly device for a mesh frame with sharp-angled edges and the bolted connection of the frame halves. In FIG. 3, 4 show the components and parts for attaching mesh frames to military equipment and options for placing mesh frame assemblies with built-in dynamic protection over the projection of an armored combat vehicle.

The arrangement of mesh frames with built-in dynamic protection can be made as follows. Steel or Kevlar rectangular mesh frame 1 is made of two mirror-made halves, fastened at the edges with a bolted connection 2, with the edges outward, forming an acute-angled edge of the frame 3 and in the perimeter of the contact plane of the frame halves 1, have grooves for pinching the mesh 4, and one of the sides of the mesh frame 1 is made flat 5, with edges inside the frame, and all edges have holes for bolts 6 (Fig. 1, 2). The flat side of the frame 5 is intended for connecting several mesh frames 1 into an assembly of roof steel mesh frames 7. The assembly of roof mesh frames 7 is made of elastic steel wire 8 using resistance welding, while each of the even crossing rods of each cell of the roof mesh frame assembly 7 is made reinforced welding joint 9. The ends of the steel wire rods 8 of the mesh frames 1 around the perimeter, when assembling the halves of the mesh frames 1, are forced behind the frame profile 10 (Fig. 2) and pinched using a bolted connection 2, in the gap between the pinch grooves of the mesh 4. Under mesh frames 1 with the help of upper rods 11 attached subframe 12, made with sharp-angled edges, one-piece, from a steel profile in the form of a reduced rectangular projection of the rectangular mesh frame 1 and below is rigidly connected using lower rods 13 (Fig. 3) with vertical or inclined quick-release racks 14, which are inserted into the bases of the racks 15 (Fig. 4), which are attached to the armor of the turrets of combat vehicles with the possibility of their rotation (Fig. 3, 4). At the intersection of each even-numbered wire of the roof mesh frame assembly 7, there are built-in dynamic charges 16, ready to be initiated from a break in the welding joint 18, which are pressed onto the detonation phlegmatizers 17, which prevent detonation from abnormal vibrations and impacts, applied to each joint of the even rods made of steel wires 8, to in which, before pressing the explosive into places of maximum pressure before the destruction or rupture of the welding joint 18, instantaneous contact capsule fuses 19 are glued.

The device of lightweight roof mesh screens with built-in dynamic protection (EDP) to protect armored vehicles from roof-mounted ammunition works as follows. Ammunition from loitering drones or ATGMs with tandem roof charges 21 (Fig. 1) fly into the assembly cell 20 of the roof mesh frames 7 and destroy the welded joint 18 of each even rod of steel wire 8, into which a dynamic charge 16 with an instantaneous capsule detonator 19 is built. detonators 19 from the rupture of the welding joint 18 initiate the detonation of the dynamic charge 16, at a distance from the armor of the combat vehicle. The rupture of the welding joint 18 occurs from the entry into cell 20 of the mesh frame 1 of ammunition 21 larger than the dimensions of cell 20 (Fig. 3, 4). In the upper hemisphere, above the tank, the first charge of tandem ammunition 21 is detonated, which instantly initiates the release of a cumulative jet remote from the armor. At sharp angles of approach and delay in contact of the approaching ammunition 21 with the dynamic charge 16, detonation of the charge can immediately destroy its cumulative funnel. The sharp-angled edge of the frame 3 of the assembly of the roof mesh frames 7 protects the charges 16 from being hit by flatly approaching bullets and small-caliber projectiles. The action of the detonation wave from the detonation of the first charge of tandem ammunition 21 is not capable of destroying the rods of steel wire 8, mesh 20, and the assembly of roof mesh frames 7 in which it was detonated. The explosive of adjacent dynamic charges 16, selected using detonation phlegmatizers 17, do not react to the detonation of ammunition 21 flying into cell 19 and remain ready to meet the next ammunition (Fig. 1, 2). Of all the known metal profiles, detonation of wire and round steel rods of small diameter requires the largest amount of explosives and is recommended with a TNT charge weighing at least 200 grams (from open sources on explosives). To select an acceptable high explosive for filling dynamic charges 16, it is possible to use paraffin-based phlegmatizers, IVV and BVV detonation protectors. The mass and dimensions of the dynamic charge 16 are carried out on the basis of calculating the minimum safe distance for the transfer of detonation to the shells of the nearby dynamic charges 16 in the mesh frame 1. The high explosive for the dynamic charges 16 is selected to be as insensitive to impact and bullet penetration as possible. Based on the test results, the most resistant to external, non-standard influences are selected: explosive explosives - for detonator capsules and explosive explosives - for shell dynamic charge 16. Welding of the damaged joint and pressing of a new explosive charge into it is carried out in remand battalions stationed in front-line combat areas. Considering the urgent need for a quick and economically justified inexpensive technical solution to protect military equipment from damage by loitering ammunition and high-precision roof-mounted ATGMs, the solution proposed by the author for attaching small charges of dynamic protection at a distance from the armor in light mesh screens made of steel wire makes it possible to equip them with the proposed devices in the shortest possible time first of all, all tanks involved in a combat operation in a neighboring state.

The prospect for the development of the proposed technical solution is the possibility of creating side, raised into the upper hemisphere, lightweight mesh screens with dynamic protection of the side, rear, front and top projections of military equipment. The effect of using roof mesh screens with built-in dynamic protection can save crews and armored combat vehicles from defeat on the battlefield.
