Description

The invention relates to ammunition, namely to engineering mines installed on the ground using remote mining equipment against armored vehicles and enemy personnel.

Known anti-tank mines of oriented installation AT-2 (DM1233) Germany, NV-876 England, etc., having a body in the form of a high cylinder, a warhead with one cumulative lining, installation device after hitting the ground and anti-tank mines of non-oriented installation BLU-91/ B, M70, M73, M75, having a body in the form of a low cylinder, a warhead with two cumulative linings at the ends and not requiring orientation after installation on the ground (Catalog “Jane's Mines & Eod OperaTional Guide. 2017-2018”)

Compared to mines BLU-91/B, M70, etc., made in the form of a low cylinder and not requiring orientation after installation on the ground, mines made in the form of a high cylinder contain a warhead with one lining, an installation device (for example, a mine AT-2) and have greater armor penetration in an armored barrier at a distance of 500 mm, for example, the AT-2 mine has an armor penetration depth of L~140 mm, and the M70 mine L~50 mm, which is suitable for hitting modern tanks from the bottom with an increased level The armor protection of the bottom is insufficient.

There are known anti-personnel mines of oriented installation: the domestic anti-personnel jumping fragmentation mine POM-2 with thread stretchers as a reaction organ (“Destructive means and ammunition”: Textbook / A.V. Babkin, V.A. Veldanov, E.F. Gryaznov, etc. Under the general editorship of V.V. Selivanov - M.: Publishing House of Moscow State Technical University named after N.E. Bauman, 2008, p. 296), anti-personnel mine with a proximity fuse of the seismic principle of operation POM-3 (RU patent No. 2493535 ) and etc.

The disadvantages of these PTMs and PPMs are:

- the use of both types of mines (anti-tank and anti-personnel) to create mixed minefields;

- anti-tank mines are used with a non-contact fuse of a magnetic principle of operation, which does not react to a person, which facilitates their neutralization, for example, by detonating a overhead charge;

- anti-personnel mines are used with a non-contact fuse with a seismic target sensor, which greatly facilitates their clearance, for example, by passing armored vehicles.

A multi-purpose remote-launched cluster mine (RU Patent No. 2638594 C1) was selected as the prototype of the proposed remote-launched mine.

The mine contains a body in the form of a low cylinder, a non-contact fuse, a detonating device, an electric detonator and electric igniters, a safety-cocking device, an inclination angle sensor, a retractable warhead (warhead) with a cylindrical charge located in the guide cylinder, at the ends of the warhead there are cumulative recesses lined with metal.

The disadvantages of this mine are:

- the presence of two cumulative linings at the ends of the warhead worsens the armor-piercing effect of the mine compared to the armor-piercing effect of a mine that has a warhead with one cumulative lining and a complex mechanism is required to ensure the detonation of the explosive charge from the opposite end of the cumulative lining, including an inclination angle sensor, a retractable combat part, multi-point initiation detonating device;

- extending before operation, to free the fragmentation shell from the shielding action of the body, the warhead significantly complicates and increases the mass of the mine design: a guide cylinder, an extension device, a detonating device consisting of receiving detonator blocks placed in the holes of the fragmentation shell, transmitting detonator blocks placed in the holes of the guide cylinder, and they must be aligned after the warhead is extended, detonator tracks of equal length on the outer side surface of the guide cylinder connecting the receiving detonator blocks with the detonator block located in the central section of the guide cylinder;

- the absence of a stabilizer, the displacement of the warhead relative to the center of the mine body towards its side surface and the chaotic unstabilized flight of the mine in the air due to this when the mine falls into soft wet soils (the number of impacts of the DORNII dynamic density meter 1...4, soil category I according to the method of Professor Zelenin A .N. GOST 16469-79) from a great height will ensure that the mine does not rebound and the mine can sink in an unoriented position.

The technical problem to be solved by the technical solution claimed as an invention is to increase the effectiveness of remotely deployed cluster mines by ensuring their destructive effect on both manpower and armored vehicles, as well as by eliminating the shortcomings of analogues and the prototype.

The technical result is:

- readiness of the warhead for combat use against armored vehicles and manpower after installing a mine on the ground, without additional actions;

- placing the upper part of the non-contact fuse over the warhead to prevent foreign objects (water, snow, etc.) from entering the cumulative lining of the warhead after installing the mine on the ground. Before detonating the warhead of a mine, the upper part of the non-contact fuse is fired to ensure the normal formation of a cumulative jet;

- increasing the likelihood of installing a mine in a workable position and ensuring the return of the mine to a position close to vertical after hitting a mine with a tank caterpillar or a car wheel.

To solve the problem and ensure the technical result, the multi-purpose remotely mounted cluster mine claimed as an invention contains a cylindrical body in which a warhead with a cylindrical explosive charge and a fragmentation shell of a given fragmentation is placed; at the end of the warhead there is a cumulative recess lined with metal, a non-contact fuse a device, a stabilizer in the form of a parachute, attached to the mine when it is placed in a cluster munition (not shown in the illustrations), an installation device with spring-loaded legs. The cylindrical body of the mine consists of structurally integrated bodies of the warhead and a non-contact fuse to ensure the readiness of the warhead for combat use against armored vehicles and manpower after installing the mine on the ground without additional actions. In addition, reducing the diameter of the mine body, due to this, reduces the likelihood of detecting a mine in a minefield and improves composability into cassette media. The fragmentation shell with a given fragmentation of the warhead is not shielded by anything and, unlike the prototype, does not require any manipulations (for example, extending the warhead) before detonation, which simplifies the design of the mine.

The non-contact fuse consists of two parts. The upper part of the non-contact fusing device is designed to release the parachute with the simultaneous opening of the arms and installation of the mine in the working position and to prevent foreign objects (water, snow, etc.) from entering the cumulative lining of the warhead after installing the mine on the ground. Before detonating the warhead of a mine, the upper part of the non-contact fuse is fired to ensure the normal formation of a cumulative jet. At the bottom of the non-contact fuse there are elements and devices that ensure the mine’s functionality against enemy armored vehicles and manpower, and the ability to enter the self-destruction time. A stabilizer in the form of a parachute significantly reduces the speed of the mine in the air and stabilizes the mine in flight.

An installation device consisting of six legs, spring-loaded with two types of springs, increases the likelihood of installing a mine in a working position and ensures that the mine returns to a position close to vertical after hitting a mine with a tank caterpillar or a vehicle wheel; in the transport position, the spring-loaded legs are pressed against the mine body with the help of two covering legs, fixed with two burst bolts. Fastening the legs of the installation device in the expanding part of the body at the base without intermediate parts (such as, for example, the POM-3 mine Patent RU No. 2493535 has a clip, a threaded bushing), improves the contact of the mine with the ground.

Safety in operation of the proposed mine (mechanical protection stage) is ensured by placing a spring-loaded stopper in the mine, which ensures a break in the fire chain, with a technological pin, which in the transport position fixes the stopper in a safe position, and before installing the mine in the cassette, the pin is removed, the stopper is recessed into the body fuse and is fixed by a guide in the cassette, and after shooting the mine from the cassette, the stopper flies out and the fire chain is closed, i.e. The protection level is removed.

The invention is illustrated by drawings: FIG. 1 - the design of the mine in its longitudinal section (the parachute is not shown); fig. 2 - side view of the mine; fig. 3 - cross section of a mine in plane B; fig. 4 - section of the assembly of fastening the metal lining to the warhead body; fig. 5 - top view of the mine; fig. 6 - view of the mine from below; fig. 7 - view of the mine in the transport position; fig. 8 - view of a mine in a combat position.

The drawings indicate: 1 - the lower part of the non-contact fuse; 2 - upper part of the non-contact fuse; 3 - fragmentation shell of a given warhead fragmentation; 4 - warhead with a cylindrical explosive charge; 5 - wire line; 6 - casing; 7 - electrical connector of the lower part of the non-contact fuse; 8 - temperature, pressure sensor; 9 - explosive bolt-clamp; 10 - cumulative notch; 11 - metal cladding; 12 - detonator; 13 - technological check; 14 - spring-loaded stopper; 15 - covering tab of the installation device; 16 - foot of the installation device; 17 - spring on the foot of the installation device; 18 - spring axis on the installation device foot; 19 - trapezoidal spring; 20 - pad on the foot of the installation device.

The claimed multi-purpose remotely mounted cluster mine contains a cylindrical body consisting of a lower part (1) and an upper part (2) of a non-contact fusing device and a fragmentation shell of a given warhead fragmentation (3), which houses a non-contact fusing device that reacts to manpower and armored vehicles , a warhead with a cylindrical explosive charge (4), at the end of which there is a cumulative recess (10), lined with metal (11) and a fragmentation shell of a given crushing (3). The metal lining (11), to reduce misalignment when installed in a flat part, has a lower flange of a larger diameter than the upper one, and when installed on the end of the fragmentation shell, the warhead (3) has a predetermined crushing of the warhead (3) with a protrusion having a greater height than the flat part of the metal lining, when creating of a certain pressing force onto the fragmentation shell of a given warhead fragmentation (3), the metal lining is evenly pressed around the entire perimeter.

The upper part of the non-contact fuse (2) contains bursting bolts (9). At the bottom of the non-contact fuse there are elements and devices that ensure the mine’s functionality against enemy armored vehicles and manpower, and the ability to enter the self-destruction time. The lower and upper parts of the non-contact fuse are connected to each other by a wire line (5) located in the casing (6).

The installation device consists of six spring-loaded legs (16), of which two spring-loaded legs are female (15). Springs (17) are placed on the legs, which, by means of an axis (18) fixed in the conical part of the body of the lower part of the non-contact fusing device (1), connect the legs to the body of the mine and a trapezoidal spring (19) with one end resting on the conical part of the body (1) , and the other end into the pads on two adjacent legs.

The stabilizer in the form of a parachute (not shown in the drawings) is attached to the mine with explosive bolts - clamps (9) when it is placed in a cluster munition.

The action of the proposed multi-purpose cluster mine occurs as follows.

Before using a mine in a cassette, the required self-destruction time is entered through the electrical connector (7) of the non-contact fusing device and the correctness of its input is monitored. In the transport position, the mine, while in the cassette, is safe, since the spring-loaded stopper (14) is recessed into the body of the lower part of the non-contact fusing device (1) and is fixed by a guide inside the cassette, and after shooting the mine from the cassette, the stopper flies out and the fire chain is closed, i.e. .e. The protection level is removed. When shooting from a cassette, the temperature and pressure sensor (8) is affected by a fire pulse, which initiates the launch of the electronic retardation device. After the block with mines leaves the cassette cup and from the moment the block with mines separates along the flight path, the electronic time for long-range arming of the mine begins.

After dividing the block with mines into a flight path, the mines fall into the oncoming air flow and are stabilized using a parachute, which reduces the speed of the mine and makes it approach the ground in a position close to vertical. After a mine falls on the ground, after a certain time has elapsed, the non-contact fuse device gives a signal to fire the explosive fixing bolts (9).

The explosive bolts - the clamps holding the spring-loaded legs (15, 16) and the parachute - are fired.

Under the influence of the spring-loaded legs of the installation device, the mine is installed in a position close to vertical. When a signal appears about detection of a target (armored vehicles, single or group enemy personnel), the non-contact fuse (1) sends a signal to reset the upper part of the non-contact fuse (2), after which, with a certain time delay, a signal is issued to the detonator (12) for detonation warhead (4) of the mine.

In the absence of a target, the proposed remotely mounted multi-purpose (anti-tank and anti-personnel) cluster mine self-destructs after the expiration of the mine’s self-destruction time set in the cluster munition before using it.

Thus, the warhead of the proposed mine, due to the cylindrical body of the mine, consisting of structurally integrated bodies of the warhead and a proximity fuse, after installing the mine on the ground for combat use against armored vehicles and enemy personnel, does not require additional actions and does not extend from the mine body , unlike the prototype.

The warhead extending from the mine body, like that of the prototype, before operation, to release the fragmentation shell from the shielding effect of the body, significantly complicates and increases the mass of the mine structure: a guide cylinder, an extension device, an inclination angle sensor, a detonating device consisting of receiving detonator blocks, placed in the holes of the fragmentation shell, transmitting detonator blocks placed in the holes of the guide cylinder, and they must be aligned after the warhead is extended, detonator tracks of equal length on the outer side surface of the guide cylinder, connecting the receiving detonator blocks with the detonator block located in the central section of the guide cylinder.

Placing the upper part of the non-contact fuse above the warhead prevents interference from entering the metal lining, and dropping it before detonating the warhead of the mine ensures the normal formation of a cumulative jet.

An installation device consisting of six legs, spring-loaded with two types of springs, increases the likelihood of installing the mine in a working position and ensures that the mine returns to a position close to vertical after hitting a mine with a tank caterpillar or a car wheel; in the transport position, the spring-loaded legs are pressed against the body of the mine.

The invention will significantly increase the efficiency of remote mining and reduce the cost of installing a mixed (anti-tank, anti-personnel) minefield by reducing the range of mines, since the claimed mine provides an effective destructive effect on both enemy personnel and armored vehicles.

Technical documentation for the proposed multi-purpose remotely deployed cluster mine has been developed and tests of manufactured samples have been carried out, confirming the operability, efficiency and safety of its operation.
