Abstract

FIELD: protection of armoured vehicles.

SUBSTANCE: group of inventions relates to variants of additional protection of the body of an armoured vehicle, made in the form of at least one flexible screen installed with overlapping of the protected area of the front/aft projection of the body. The flexible screen is formed from at least two protective modules located predominantly at an angle in the working position, connected by at least one strong flexible elastic connection, made with the possibility of bending the module(-s) into the body elements until the stop when the vehicle hits an obstacle. One of the modules is made with an element that ensures its rotation on the axis or coaxial axes, rigidly fixed on the body or itself. Each module contains at least one front armour plate and at least one rear plate with at least one inner layer located between them. According to the first variant, the flexible screen is held by at least two braces that are shortened in length and are in the expanded state, which withstand tensile loads when the screen is bent until the contact of the modules and the body elements; the braces are fixed on opposite sides in the transverse direction from the axis of rotation of the rotary module and its connection with its adjacent module. According to the second variant, the screen is held by at least one clamp, which limits the rotation of the rotary module on the axis(axes), which is shortened in length, being in the expanded state, by a brace fixed on the other side in the transverse direction from the axis of rotation of the rotary module and its connection with the adjacent module. According to the third variant, the screen is made with the possibility of bending directly unconnected with the housing module(-s) to the elements of the housing as a result of external influence and is held by at least one clamp, excluding the rotation of at least one rotary module on the axis(axes), while the connection(-s) is (are) made with the possibility of holding in the working position directly unconnected with the module’s (-s’) housing.

Description

The group of inventions relates to the field of additional (mounted) armor protection of the frontal and aft projections of the hull of an armored vehicle (hereinafter - TS), can be used in the construction of tanks, infantry fighting vehicles, armored personnel carriers, engineering vehicles and various armored combat vehicles for protection against cumulative and kinetic armor-piercing weapons, specifically - to a flexible quick-detachable screen modular protection, which allows, when the vehicle moves through obstacles (for example, a forest, destruction in urban areas, blockages, organized barricades) forward or reverse, respectively, to reduce or eliminate damage to the screens and their fasteners when the vehicle hits an obstacle, while maintaining the protection of the vehicle body, as well as improve armor protection (in comparison with rubber-fabric, lattice, mesh or chain screens in terms of increasing the effectiveness of countering weapons).

In combat conditions, it is impossible to completely remove obsolete vehicles that do not meet modern security requirements from service and quickly replace them with new ones. At the same time, the strengthening of the armor protection of vehicles that are still in operation, which have not squandered their entire resource, is carried out constantly.

Improving the armor protection of the vehicle is also associated with the search for new ways to install it.

Taking into account the realities of modern military conflicts, the issues of improving additional (hinged) protective screens in terms of increasing the effectiveness of countering weapons, ensuring their survivability, which also depends on the design of the screens and their fastening at the facility, as quickly as possible installation and dismantling, are becoming more relevant.

In recent military conflicts, it became necessary to develop a new additional (mounted) protection for the frontal and aft projections of the vehicle hull.

On the frontal and aft projection of the vehicle hull, additional protection is especially susceptible to external influences when the vehicle hits obstacles and should be developed taking into account the provision of:

- flexibility (compliance) until it stops against the strong elements of the body;

- strength and rigidity of its elements, including fasteners;

- elasticity (to restore the original shape);

- quick-detachability (for replacing screens and access to elements of the body and chassis of the vehicle).

To increase the security of vehicles, various screens were widely used earlier and are still used: lattice, mesh, chain, hinged sheets of metal or rubber.

The task of screens of all types is to initiate the operation of ammunition at a considerable distance from the armor, resulting in a reduction in penetration, or deformation of the anti-tank weapon, rendering it unusable [Protection of armored vehicles: threats and solutions, URL: https://topwar.ru/92302- zaschita-bronetehniki-ugrozy-i-resheniya.html, published: 15.03.2016 (date of access: 10.01.2023)].

In real combat conditions, simpler and more affordable means sometimes turn out to be the most effective, therefore, the protection of the first generations is still used and will be used, while it is important that these means are used competently and most effectively [E. Chistyakov, D. Kupryunin, M. Alekseev, A. Kimaev. The effectiveness of additional protection of military equipment // Equipment and weapons yesterday, today, tomorrow. - 2017. - No. 2. - S. 2-12].

From the source [DE 3638841 C2; Track cover for combat vehicles, IPC: B62D 55/088; F41H 5/013; F41H 7/04 / Applicant: KRAUSS MAFFEI AG (DE)-DE3638841 A; applied: 11/13/1986; publ.: 19.05.1988] known collapsible protection caterpillars containing a base plate mounted on the lower edge of the body of the vehicle and hinged to the upper edge of the casing of the caterpillar, thereby providing additional ballistic protection; attached to the base plate - the upper armored package, pivotally connected to the upper edge of the casing; the lower armored pack, pivotally connected to the lower edge of the base plate, which can be fastened in the folded state from the outside to the base plate, and also, in the folded state, rotate into the free space of the chassis with its subsequent fixation.

The foldable base plate provides easy access to the undercarriage for maintenance work.

When no reinforcement of ballistic protection with armored packages is required, only the base plate is used.

The base plate may consist of a single-layer or multi-layer reinforcing plate, while the latter can also be reinforced in separate areas not covered by the armor package.

This protection refers to the protection of the sides of the vehicle. The use of such a design to protect the frontal or aft projection of the vehicle hull, without fixing its position, will lead to the buildup of the armored pack on the hinge and the impacts of the armored pack on the hull, and the fixed position of the armored pack when the vehicle hits an obstacle will lead to its breakage.

The possibility of an inclined position of the protective modules in the claimed invention ensures their more efficient operation (in the form of dynamic protection with elements of dynamic protection, hereinafter referred to as EDZ, or in the form of an inextricable protection, hereinafter referred to as NRZ) compared to the vertical position of armored packages of known protection.

From the source [DE 102007002577 A1; Schutzgitter, IPC: F41H 5/02; F41H 5/06; F41H 7/04 / applicant: RHEINMETALL LANDSYSTEME GMBH (DE) - DE102007002577 A; applied: 10/11/2007; publ.: 17.07.2008] a flexible grid is known for protection, in particular, from cumulative projectiles.

Known protection, according to the applicant, even in extreme situations provides easy and convenient access to the desired areas of the facility; it can be attached in certain areas, for example, only at the rear of the object, when it is sufficient to protect only from incoming projectiles from certain directions, which can reduce additional weight. It is possible to combine a protective grid with other known means of protection against cumulative projectiles.

In the development of this invention, it is provided that the protective grille is made removable (disassembled into separate sections), while it is folded or rotated for further transportation at the facility.

The problems of rigid or semi-rigid protective frames such as lattices used to protect the hull and turret from all sides were previously identified in the description of the invention "Shielded Armor" [RU 2655590 C1, IPC: F41H 5/06 (2006.01) / patent holder: Joint Stock Company "Ural design transport engineering" (RU) - RU 2017114086 A; applied: 04/21/2017; publ.: 28.05.2018], namely:

- restriction of crew access to the object or parts of the object for operational maintenance without time-consuming dismantling of the screen;

- low adaptability to operating conditions;

- low overall throughput.

When overcoming large obstacles or narrow oversized passages, any force impact (touching the obstacle with a rigid frame) in the absence of compliance of the screen frame can lead to its deformation or breakage.

After the termination of the interaction of the obstacle with the known shielded armor, the possibility of taking the elements of the shield of the original shape is provided by flexible links that are shortened in length, strong to break (steel cables, chains) or tensile links made of rubber, polyurethane, etc. - under its own weight of the screen, and in the claimed invention - due to the elasticity of a strong flexible connection.

At the same time, in contrast to the claimed invention, where the protective modules are made in the form of strong flat solid packages without cutouts, it is possible that the elements of the lattice screen (flexible lattice, shielded armor) are firmly engaged with an obstacle in the form of reinforcement, etc., with its subsequent breakage or deformation with any design of links (strong flexible in the form of chains, cables or tensile ones made of rubber, polyurethane, etc.).

From [US 20140224108 A1, PROTECTION MEMBER FOR A PROTECTION DEVICE AND A VEHICLE WITH SUCH A DEVICE; IPC: F41H 7/04 (2006.01); F41H 5/02 (2006.01); F41H 5/013 (2006.01) / applicants: -US2014345885 A; convention priority: 09/21/2011, SE1150861; applied: 09/18/2012; publ.: 14.08.2014] protection in the form of curtains is known, containing wire elements located at a distance from each other along the corresponding side of the combat vehicle hanging close to the ground, without swinging.

In comparison with the claimed invention, such a design, like lattice screens, protects the vehicle with less efficiency [Protection of armored vehicles: threats and solutions, URL: https://topwar.ru/92302-zaschita-bronetehniki-ugrozy-i-resheniya.html , published: 03/15/2016, (date of access: 01/10/2023)] and does not provide protection against kinetic ammunition.

From [SHIELD FOR A LAND VEHICLE MOUNTED ON WHEELS OR TRACKS; IPC: F41H 5/02 (2006.01); F41H 5/04 (2006.01); F41H 5/06 (2006.01) / applicant: CLOUTH GUMMIWERKE AG - GB4023471 A; convention priority: 10/01/1970, DE2048205 A; applied: 08/27/1971; publ.: 08/30/1973] a screen is known that contains a plate of elastic material, several adjacent metal plates with holes, each of which is individually enclosed in a plate of elastic material (non-combustible rubber), and at least a sheet of fabric material completely embedded in plate, with each sheet of fabric material located next to the corresponding side of the metal plates.

The gaps between the metal plates allow the screen to flex, while the built-in fabric material keeps the screen stable and increases the screen's tear resistance.

Preferably, at least one bolt hole is provided on each side edge of each shield part, through which a connecting link is attached to each pair of adjacent shield parts. The connection between two adjacent parts of the screen is usually made with a connecting link, which is connected to each screen with a corresponding bolt.

At the gaps between adjacent metal plates and in the area of the holes, the fabric material sheets extend inwardly towards the central plane of the metal plates.

Disadvantage: low survivability of the screen fastening when moving the vehicle through obstacles, tk. the screen is firmly fixed.

Known side screens with integrated EDS installed along the sides along the entire length of the body of the object. Such screens are installed on T-72BZ, T-90MS, T-90M, T-80BVM tanks and other combat vehicles, in particular on BMPT [see. RU 2238508 C1 dated 10/20/2004; RU 207792U1 dated 11/16/2021].

For ease of maintenance of the undercarriage of an armored vehicle, the screens are mounted on hinges. At the same time, to move the screens to the position for servicing the running gear, it is first necessary to unscrew the bolts, remove the axles connecting the screens to each other from the hinges, raise the screen and fix it in a new position, which complicates access to the elements of the chassis of the vehicle.

The use of such a screen mount to protect the frontal and aft projections of the hull will not ensure the survivability of the screen when the vehicle moves through obstacles, because. the screen is rigidly fixed with bolts.

In order to provide access to parts of the vehicle equipment and carry out maintenance work, screens, as a rule, are foldable.

All designs of lattice, mesh, chain screens are used only for protection against RPGs with their inherent lack of effectiveness. Rubber-fabric screens (and other screens without EDS) cock RPG grenades, while the cumulative jet is slightly weakened due to the span of the distance to the hull. Latticed and chain screens, when an RPG grenade fuse hits the screen elements, work in the same way as rubber-fabric ones, and if the fuse does not hit the screen elements for some grenades, with some probability they exclude their regular detonation [Improving the protection of armored vehicles from melee anti-tank weapons, URL: http ://www.btvt.narod.ru/4/defence.htm, (date of access: 01/10/2023)].

In addition, lattice screens have low survivability when the vehicle moves through obstacles (small forests, cramped conditions, etc.). Their deformation reduces the protective properties and makes it difficult to access the elements of the product for maintenance.

Rubber-fabric, lattice, mesh, chain screens, etc. (screens without EDS, considered as analogues) do not provide effective protection against cumulative weapons and do not have protective properties against kinetic ammunition (armor-piercing sub-caliber projectiles).

Based on this, the frontal and aft projections of the vehicle hull must be protected with the elimination of these shortcomings of the known screens.

The relevance of the claimed group of inventions is determined by the need to create a new, different from all known analogues, additional protection of the body of the vehicle, installed on its frontal and / or aft projection, which is simply and reliably mounted, allows maneuvering the vehicle and external influences (when hitting obstacles - trees , blockages, barricades, etc.) to ensure the survivability of screens.

The proposed protection does not require labor-intensive retrofitting of the vehicle (because standard hull elements are used for its installation, and unlike the known hinged side screens, for which bolts are used, there is no need in the claimed technical solution to fix the screens).

As analogues of the invention, the following technical solutions are considered, similar in purpose to the claimed additional protection:

1) Additional armor for combat vehicles is known [DE3 706775 A1, Additional armor which can be repositioned locally; IPC: F41H 7/04 / applicant: INDUSPJEANLAGEN BETPJEBSGES (DE) - DE3706775 A; applied: 03/03/1987; publ .: 09/15/1988], which, according to the applicant, allows to provide a higher overall level of protection for combat vehicles due to the fact that armor elements can be installed in the position that is most important for increasing protection (in which they provide maximum protection for a particular situation ) taking into account the change in the direction of the threat with the help of appropriate guides and rotary devices.

Additional armor can be made with the displacement of the elements in the guides and/or folding around the fixed pivot points.

Elements can consist of several interconnected sub-elements.

Elements can be installed with the ability to move manually or using electric, hydraulic drives.

Disadvantages: the presence of drives (electric, hydraulic, manual) complicates the design of protection, makes it less tenacious in case of operational damage. Breakage of the drive or guides with the position of the armor elements providing protection against threats from above makes it impossible to turn the tower and use weapons; in contrast to the claimed invention, where the increase in the survivability of protection is provided in the working position (without restrictions on the use of weapons of the vehicle).

2) A protective device is known [US 5625160 A, Protection arrangement for affording protection from an approaching projectile; IPC: F41H 5/007; F41H 11/00 / applicant: DIEHL GMBH & CO (DE) - US 60233496 A; priority: 18.02.1995, DE 19505629 A; applied: 02/16/1996; publ.: 02/16/1996], designed to protect the hull of a battle tank in the direction of its movement forward from the effects of armor-piercing shells using protective plates that can be discarded, without transferring the load to the supporting structure and without limiting operational functions.

The protective device contains:

- front strong support (for example, in the form of a tubular frame structure, reinforced with a lattice frame, having a shock-absorbing rear lining), wedge-shaped in longitudinal section, protruding beyond the front of the tank; made with the ability to repel obstacles or fell trees without serious damage;

- at least one module mounted on the front support in an inclined position, which is a multilayer structure consisting of two plates of armored steel, located parallel to each other, between which is preferably a layer of high-energy explosive.

Disadvantages: the protective device in cramped conditions complicates the maneuvering of the tank (due to the device protruding beyond the front of the tank), impairs maneuverability (by limiting the ability to overcome obstacles, such as a “wall” due to the overlapping of the caterpillar branches with the protective device), restricts access to chassis elements for maintenance, due to the heavy, durable (for felling trees) front support (with a tubular frame structure reinforced with a trellis frame), it increases the overall dimensions of the vehicle during transportation.

3) A device is known for protecting armored vehicles from cumulative projectiles [US 20060162538 A1, Protective device for armored vechicles, particularly for protecting against hollow-charge projectiles; IPC: F41H 7/02 (2006.01) / Applicants: Pfenning Michael (DE); Kellner Gerd (DE) - US54891805 A; priority: 03/11/2003, DE 10310952 A; international filing date: 02/28/2004, DE2004000373W; publication of the PCT application: 23.09.2004; publ.: 07/27/2006], containing at least one protective module installed in front of the outer side of the protected surface, made with the possibility of moving from a non-working position, in which it is located in a given fixed position (as close as possible to the protected wall), in the working position (under threat), in which, at least partially, it is located at a significantly greater distance from the protected wall than in the non-working position.

Protective modules can be made both active and passive; in the form of a package of several multilayer plates; in the form of blinds with many inclined layers.

In one of the options, the protective module is made of two parallel plates spaced apart from each other, with the possibility of rotation on an axis parallel to the protected surface.

As a result of the inclined position of the plates (in the working position of the protective modules), optimal protection against cumulative projectiles is achieved.

Disadvantages: in order to protect against a possible threat, the protective module must be transferred from the non-working position to the working one, spending time on this, which is inconvenient during operation, unlike the claimed protection, in which the protective modules are always in the working position, while the flexible screen occupies the non-working position only when it hits an obstacle. In the claimed invention, after the termination of the impact of the obstacle on the modules, the screen assumes (without the participation of a person and drives) the working position due to the elasticity of the flexible connection. In addition, in order to reduce the size during transportation, the claimed protection, in contrast to the specified one, is made quick-detachable.

4) A movable removable lattice screen is known [EP 2020585 B1, Mobile and preferably removable SLAT-protection for vehicles; F41H 5/02 (2006.01); F41H 7/04 (2006.01) / Patent holder: RHEINMETALL LANDSYSTEME GMBH (DE) - EP 08013510 A; priority: 31.07.2007, DE 102007036393 A; applied: 07/26/2008; publ.: 04.02.2009, EP 2020585 A2], designed to protect areas of the vehicle that should not be damaged, especially when driving off-road (in particular, the front and rear of the vehicle).

The design of the previous grating screens is characterized by the minimum possible distance from the ground to the lower edge of the screen.

The known screen contains lattice panels connected to each other by movable connecting elements (such as metal springs, hinges, chains, hinges, rubber elements, etc.), so that the panels can deviate when they hit the ground (when the vehicle hits an obstacle e.g. unevenness or embankment). When the vehicle leaves an obstacle, the panels are also deflected due to the movable connecting elements.

The screen is attached to the body of the vehicle using brackets with eyelets, so that the screen brackets perceive the loads from the screen in motion and interaction with obstacles. In this case, the degree of mobility or rigidity of the screen is regulated by changing the design and the number of connecting elements. The dismantled screen can be attached to suitable elements on the vehicle using connecting elements.

Disadvantages: the lattice screen does not protect against kinetic weapons, it is used for probabilistic protection against anti-tank cumulative grenades; unlike the claimed invention, the lattice screen has a low survivability in operation when the vehicle overcomes obstacles in the form of barricades, rubble, ruins (the screen may be caught on reinforcement) or in the forest (the screen may be caught on stumps and fallen trees). The screen caught on such obstacles is deformed and cannot properly perform its protective function.

5) Known armor mounting system [GB 2481510 B, Armor mounting system for a vehicle; IPC: F41H 5/013 (2006.01) / patent holder: The Secretary of State for Defense (Incorporated in the United Kingdom) (GB) - GB 2481510 A; priority: 06/22/2010, GB 201010419 A; international filing date: 06/20/2011, GB 2011000914 W; publication of the PCT application: 29.12.2011, WO 2011161399 A1; Appl.: 16.06.2011, GB 201110175 A; publ.: 12/28/2011], designed to reduce damage to the armor elements installed on the vehicle during its maneuver (due to the elastic support of the armor elements, which ensures the return of the armor element to its original position after the deflection of the armor element as a result of the vehicle maneuvers).

For attaching the armor to the vehicle, the known system uses a flexible bracket fixed between the vehicle and the armor element with an elongated elastic element to maintain and return the armor elements to their original position after deflection.

Flaws:

- armor elements on such elastic elements of a vehicle moving over rough terrain can unpredictably move relative to its original position, which can cause unwanted collisions with the elements of the vehicle (unlike the claimed protection, in which the flexible screen is held by braces, and its position is clearly defined by the axis and pumping to a hard stop in the body elements);

- armor elements are not connected to each other, so their unpredictable movements relative to each other can lead to their mutual displacement from the initial position and "biting" in an undesirable position (unlike the claimed protection, in which the protective modules are connected by a flexible elastic connection);

- armor elements of a large mass cannot be held on an elastic element (in contrast to the claimed protection, in which protective modules are held on strong rigidly fixed axes);

- fastening of armor elements with bolts is laborious, not quick-detachable (unlike the claimed protection, which is quickly mounted and dismantled).

6) Known "Protection device against anti-tank cumulative grenades" [RU 2534485 C1; IPC: F41H 5/00 (2006.01); F41H 5/007 (2006.01) / patentee: OAO NIIstal (RU) - RU 2013129740 A; applied: 06/28/2013; publ.: 11/27/2014], which is a screen in the form of a base (for example, a solid part 40 mm thick made of PPU-355 polyurethane foam) with metal volumetric protective elements, installed in front of the protected object at a distance, for example, using stretch marks in the form of straps, sewn around the perimeter of the base.

Disadvantages: the protection device in the form of a mesh screen does not protect against kinetic weapons, it is used for probabilistic protection against anti-tank cumulative grenades; in contrast to the claimed invention, the mesh screen has a low survivability in operation when overcoming obstacles (it is possible that the screen may catch on the reinforcement in the ruins, knots of trees and its subsequent breakage due to the low strength of its base). Caught on such obstacles and a torn screen cannot properly perform its protective function.

7) Known tank T-72B with the protection of the lower frontal parts (hereinafter - NLD) hinged complex of dynamic protection (hereinafter - NKDZ) "Contact-1" [Main battle tank T-72B. Dynamic protection. NKDZ "Contact-1". URL: http://www.btvt.narod.ru/4/t-72B.htm, (date of access: 01/10/2023)].

Disadvantages of such protection: containers of NKDZ "Kontakt-1" on the NLD can be crushed when hitting obstacles, worsening the security of the vehicle. The fastening of each container is laborious. Containers on the NLD cover its small area due to the location below the built-in equipment. The existing fastening of the containers does not allow improving the protection of the NLD by placing the containers in front of the built-in equipment without significantly compromising access to it.

8) From the source [Forum. Dressed in armor. Dynamic protection (DZ). URL: https://odetievbrony.ru/viewtopic. php?id=24, published: 02/22/2017, (date of access: 01/10/2023)] known design (BMPT "Terminator"), taken as a prototype. bullets; rubber-fabric screens with cutouts for the EDS installation, forming the inner layer of the set; rear plate with lugs, fastening elements (bolts) for tightening the set of plates along the perimeter.

Such screens are fastened with bolts with spring washers to the bars, which in turn are attached to the bulwarks with bolts with spring washers. Between themselves, the screens are connected by axes with hinges.

The purpose of the group of inventions is to create a simple and easy-to-use design for additional protection of the body of an armored vehicle, installed on its frontal and / or aft projection, which will be an alternative to the above analogs, free from their shortcomings and increase the security of the vehicle as a whole.

The technical result of a group of inventions is expressed as follows:

- in the implementation of additional effective protection of the frontal and aft projections of the vehicle hull from cumulative and kinetic armor-piercing weapons;

- in increasing the protection of the frontal and aft projections of the vehicle hull compared to previously used means of protection (lattice, chain, mesh and rubber-fabric screens) due to:

for the aft projection - effective protection (RS and / or NRZ), not previously used for modernized vehicles on their stern (RS and NRZ screens perform their function with a higher probability and greater efficiency than the screens given for comparison);

for a frontal projection - the possibility of strengthening the existing protection of the vehicle (for example, an existing remote sensing) and / or strengthening zones saturated with equipment in which it is difficult or impossible to install known protection (NKDZ "Contact-1");

- in increasing the reliability of protection by increasing the survivability of screens when the vehicle collides with an obstacle (mechanical damage to the modules that affect their protective properties is reduced or eliminated), which is ensured by the strength of the front armor plates of the modules;

- in the expansion of functionality due to:

protection of the elements of the chassis of the vehicle with strong modules (deflected to the stop into the elements of the body and preventing deformation of the existing equipment, i.e. less durable elements located behind the protective modules, for example, lamps, wires, pipelines, cameras, etc.). Flexible screens with protective modules work as a ram or bumper when the vehicle hits an obstacle, protecting the specified equipment, in contrast to collapsible lattice screens and pliable mesh and chain screens;

increasing the mobility (passability) of a vehicle with hinged protection in the form of screens, provided by the removal of restrictions on forward / reverse movement through an obstacle, for example, a forest (due to the survivability of the screens (strength and flexibility) and the strength of their fastenings);

Additional protection of the body 1 of the armored vehicle for each of the options is made in the form of installed outside the vehicle, at least one flexible screen; in a specific example, the protection is made of three screens 2, 3, 4.

Each screen is installed with overlapping of the protected zone of the corresponding projection of the housing 1 in the direction of the vehicle movement, i.e. for partial or complete protection of the frontal/lumbar projections of the vehicle hull.

In this case, the direction of movement is understood to mean that the body velocity vector (forward or backward) can also have a lateral component, and partial protection of the body projection can be provided by screens located with an offset from their projection onto the body along the normal to its cross section.

Each screen is formed from at least two protective modules; in a specific example, from two modules 5 and 6, each of which contains external ones - a front metal armor plate 7, a back metal plate 8, with an inner layer located between them, in particular, a rubber-fabric plate 9 passing through both modules 5, 6.

Armor plate (preferably at least 8 mm thick) can be either a solid thick-walled strong plate of armor steel or several plates of different materials fastened together and forming a solid solid structure.

The back plate is predominantly made of metal 2–5 mm thick.

The inner layer between the armor plate and the plate can be made of rubber, polyurethane, plexiglass and other materials used for NRZ, while the connection between the modules must be made strong, flexible and resilient.

The screens 2, 3, 4 are installed with the possibility of rotation on the axes 10, rigidly fixed (for example, by welding), on the body 1 (Fig. 1, 2, 4-12) or, alternatively, on the rotary module 5 (Fig. 3).

Modules 5, 6 are connected by a strong flexible elastic connection. In a specific example, the flexible link is the inner layer 9.

It is possible to perform a strong flexible elastic connection 9 from a thin sheet of spring steel, fixed to the front 7 or back 8 plates of adjacent modules from the outside or between them.

For the possibility of turning each screen 2, 3, 4 (during installation and dismantling, bending until it stops into strong body elements, for example, a stern sheet, strong brackets for vehicle equipment) on the axis 10, on the back plate 8 of the rotary module 5, lugs 11 are made (Fig. .2).

The lugs 11 can also be fixed on the front armor plate 7, as the most durable, due to the cutouts for the lugs in the back plate 8 and the middle layer 9. If the axes 10 are located on the rotary module 5, the lugs 11 can be fixed on the body 1 (Fig. 3 ).

The flexibility of each screen is provided by a flexible elastic connection 9 between adjacent modules 5 and 6 located at a distance from each other, so that the screen can be bent within its operating range without contact between the outer layers 7 and 8 of the corresponding layers of adjacent modules.

To simplify the installation / dismantling of the rotary module 5 (and the screen), each lug 11 is made with an open groove of width f, and on the axis (s) 10 with a diameter d greater than the width f (Fig. 9), reciprocal flats G with a size e , smaller than the width of the grooves f, providing the installation (by the mutual arrangement of the flat of the axis and the lug) of the rotary module 5 at an angle α different from its angle β in the working position relative to the housing (Fig. 10).

To simplify the mounting/dismantling of the rotary module according to the second and third options, the clamp 16 (as an option, with a pressure surface, like a trap), can be moved to the working position by turning on its axis without using any tool.

Each screen 2, 3, 4 is made with the possibility, as a result of external influence F, to bend to the stop by the module (when it hits an obstacle located at the level of the corresponding module (tree, stump) or modules (when it hits an obstacle in the form of a blockage) into the body elements ( Fig. 11, 12. At the same time, the elements of the vehicle body, protective modules of screens, screens assemblies provide the necessary strength when the vehicle hits an obstacle.

Each screen 2, 3, 4 is held in the working position (in which the modules are located, mainly at angles of 40 ... 60 ° to the direction of approach of the means of destruction) by two stretch marks 12 and 13 that are shortened in length (in the specific example, in the form of metal chains) located in the expanded state, fixed on opposite sides in the transverse direction from the axis of rotation of the rotary module 5 and connection 9 with the module 6 adjacent to it (i.e., the communication section between the modules).

In a specific example, the screens 2, 3, 4 are fastened to the body 1 through adapter brackets 14 and 15, on which coaxial axles 10 are fixed. the design allows to reduce the number of axles 10 for mounting several screens and, accordingly, the number of places for their attachment; to simplify the placement of brackets 14, 15 on the vehicle equipped with additional protection with the equipment already on it; reduce the cost of construction.

To eliminate the axial movement of the screens on the axes 10, beads can be made; shown with a dotted line in Fig. 2, 5, 7, 8, 10, 11, 12, in solid line - in Fig. 9.

Stretch marks 12, 13 can also be made in the form of a metal cable, a Kevlar rope, etc., and must satisfy the tensile strength condition for specific screen design options with their maximum possible bending.

In a specific example (Fig. 8), a three-layer package 17 with external metal layers and a middle non-metallic layer located with the formation of a gap x between the corresponding module and the indicated package can be fixed outside on one module 5. The three-layer package is an inextricable protection (IRZ), in combination with the DZ (provided by the module version) provides additional advantages known from the prior art.

The bonds provide the necessary screen bending due to: material properties (strength, flexibility, elasticity) and location of adjacent screen modules at the required distance from each other.

Links can also be made in the form of short elements between modules.

According to the second variant (Fig. 4, 5), screens 2, 3, 4, as well as in the first variant, are installed so that as a result of external influence they are bent until they stop by the protective modules into the elements of the housing 1, but at the same time they are held in the working position , each with a clamp 16 that limits the rotation of the rotary module 5 on its axis (or axes) and one extension 12 that can withstand tensile loads at the specified bending (in a specific example, when the lower module 6 is affected and deviates to the body 1 at a distance z, until it stops in the body 1), which is in the expanded state and fixed on the other side in the transverse direction from the axis of rotation of the rotary module 5 and its connection 9 with the module 6 adjacent to it.

In a specific case, when the clamp 16 interacts with a module that does not have an axis of rotation (Fig. 4, 5), the restriction of rotation of the rotary module on the axis (s) can be mediated through the connection 9 due to its elasticity (rigidity).

According to the third option (Fig. 6, 7), applicable mainly to protect the case in cases where it is difficult or impossible to place the module/module mounts, screens 2, 3, 4, as well as in the first option, are installed with the possibility of bending as a result of an external action against the stop of the module 6, which is not directly connected to the case, into the elements of the case 1, while each screen is held by one clamp 16, which excludes the rotation of the rotary module 5 on the axis 10 (in this embodiment, the rotary module 5 is rotated only for mounting and dismantling the screen), and connection 9 is made with the possibility of holding (due to elasticity/rigidity) the protective module 6 in the working position. (speed, destination).

Job

According to the first option, when the screen encounters an obstacle, it acts on modules 5 or 6 with force F (Fig. 11, 12), as a result of which the rotary module rotates on the axis 10 until it stops with the corresponding module 5 or 6 into the elements of the housing 1. At the same time, the flexible the elastic connection 9 between the modules bends, creating an increased voltage on the extension 13 or 12, respectively (depending on the impact on the corresponding module 5 or 6), fixed on the other side of the axis of rotation of the rotary module 5 and the flexible elastic connection 9, and the extension fixed on the module, which is affected by the obstacle, is bent, shortened in length.

According to the second option, two designs are possible, in one of which there is a gap Z between the module 6 and the housing element (Fig. 4, 5), and in the other there is no gap (Z=0) (not shown).

In the first case, where Z>0 when meeting with an obstacle of the upper module 5, it rotates on the axis 10 until it stops against the elements of the housing 1. In this case, the flexible elastic connection 9 bends, creating an increased voltage on the clamp 16, which holds the lower module 6. When In this case, the length of the clamp 16 is such that it ensures that the module 6 is held while the module 5 rests against the elements of the housing 1. The option when the rotary module is located at the bottom is not shown.

When it encounters an obstacle from the lower module 6 of the screen, it acts on the module, as a result of which it bends all the way into the elements of the housing 1, choosing the gap Z. In this case, the flexible elastic connection 9 between the modules bends, creating an increased voltage on the extension 12, fixed on the other side from the axis of rotation of the rotary module 5 and flexible elastic connection 9.

In the second case, where Z=0, upon encountering an obstacle of the upper module 5, the screen works as described above (for the upper module). When meeting with an obstacle of the lower module 6, the screen directly transfers the force to the elements of the housing 1.

According to the third option (Fig. 6, 7), when it encounters an obstacle of the upper module 6, which is not directly connected to the body 1 (the lower rotary module 5 is fixed between the clamp and the elements of the body), the upper module 6 is deflected due to the flexible elastic connection 9 and rests against body parts 1.

According to any of the options, the front armor plate provides the strength of the screen module against force F.

In either embodiment, the shield attachment and the connection between the modules provide the required strength.

According to any of the options, after the cessation of the impact of the obstacle on the modules, the screen takes the working (regular, initial) position due to the elasticity of the flexible connection 9.

Possible variants of the screen with a large (more than two) number of protective modules. At the same time, various combinations of screen fastenings on the body with braces and clamps are possible to ensure their working position after overcoming an obstacle.

The location of the axes of the rotary modules can be not only horizontal.

In the claimed protection according to the first and second options, the possibility of disengaging the rotary screen module even when the flats G of the axis 10 and the eye groove 11 are aligned is excluded due to the mutual arrangement of the flats and the direction of the external action F (for the option shown in the figures), and according to the third option (in in a particular case, when the rotary module is located at the bottom of the screen), the rotary module is fixed from rotation by a clamp, which excludes the rotation of the rotary module towards the body at an angle at which the axis and the lug are disengaged, therefore disengagement is impossible. According to the third option, when the rotary module is located in the upper part of the screen (option not shown), the rotation of the rotary module towards the housing at an angle at which the axle and lug are disengaged corresponds to the pressing force of the external action F from the side of the lug of the rotary module on the axis, excluding the disconnection of the connection .

For all variants, a different position of the rotary module for dismantling/mounting the screen cannot be ruled out. For example, one in which the rotation of the module at an angle at which the axle and lug are disengaged is excluded by a brace attached to it.

The use of well-known technical solutions:

a) hinges connecting the screen to the body, made with the possibility of quick coupling-disengagement (due to the implementation of flats on the hinge axis, which are aligned with the corresponding grooves in the lugs through which the specified axis passes when the axis is rotated) [RU 2190176 C1; Shot fixing device; IPC: F41A 9/01 (2000.01) / patent holder: Ural Design Bureau of Transport Engineering (RU) - RU 4540228/02; applied: 03/13/1991; publ.: 27.09.2002];

b) BMPT side screens

together with original technical solutions:

- fixing the screens on the axis (axes) with their retention in the working position by stretch marks and / or clamp (clamps) without fasteners requiring the use of any tool;

- return of screens to the working (original) position after bending from external influences;

- protection by hinged screens with EDZ frontal and aft hull projections

in the context of the claimed invention, ensures the achievement of the indicated technical results, which allows us to conclude that the invention is novel and does not follow explicitly from the existing state of the art, that is, it meets the patentability criteria "novelty" and "inventive step".

Thus, the use of the invention in its various variants will allow:

- to ensure the protection of the frontal and aft projections of the vehicle hull from cumulative and kinetic armor-piercing weapons;

- when the vehicle hits an obstacle, reduce or eliminate damage to additional protection due to the strength of the front armor plates of the protective modules, the strength of the fasteners, strong ties, as well as the possibility of deflecting the rotary screen module on the axis, reducing the length of the extensions and / or bending of each screen;

- restore the screens to the working (initial) position due to flexible elastic connections between the modules;

- facilitate assembly and disassembly work during the operation of the vehicle, when quick (without the use of any tools) removal of screens by one or two crew members is required to access the equipment or replace them after combat damage;

- adapt additional protection to the geometry of the hull of a particular vehicle with the available equipment to ensure the angles of entry / exit;

- adapt additional protection to any vehicle with minimal modifications (for a specific vehicle, fixing the axles rigidly, if necessary, on the body or on the rotary module; installing screens on adapter brackets; fixing screens with braces on adapter brackets);

- apply the required level of protection or increase it (by using in the screens of DZ, NRZ or their combination);

- combine proven and affordable technical solutions (flexible connection of BMPT screens, stretching in the form of a chain).

Field tests of the proposed protection showed the possibility of overcoming obstacles in the form of a forest with trees up to 200 mm in diameter without damaging the screens and their quick dismantling / assembly without any tool by one person.

To improve the security of the vehicle, the improved protection will confidently compete with the existing means of additional protection, and can be used when upgrading the vehicle.
