Description

The invention relates to ammunition, and in particular to a device for an anti-tank cumulative mine of a remote installation, which can be installed in the mining zone as a part of cartridges from helicopters, ground mine loaders and manually.

Known anti-tank mines of a remote installation that have an elongated shape to increase anti-crawler action, for example: domestic anti-tank anti-caterpillar mine PTM-1 and anti-tank mine of combined action PTM-3 (Russia's Arms, Catalog T.VII "High-precision weapons and ammunition", AOZT " Military Parade ”, Moscow, 1997, p. 638), capable of hitting a tank with a cumulative jet through the bottom, and also destroying the tank’s caterpillar.

As the prototype, the above anti-tank mine of combined action PTM-3 was selected, containing an elongated parallelepiped body with four gutter-shaped cumulative claddings, a fuse, an additional cumulative cladding located at the end opposite the fuse, and an axial channel was made in the explosive charge (BB) in which the initiating means is located, while the detonating cords transmitting detonation in opposite directions, located next to each other, are divided along the length of the meta with a plastic plate with a width and thickness of 1.0-2.0 and 0.1-0.5, respectively, of the thickness of the detonating cord and are enclosed at the contact point equidistant from the initiators in a metal shell with a length and thickness of 1.0- 5.0 and 0.02-0.5 of the thickness of the detonating cord. The listed set of features allows you to ensure the defeat of armored objects with a PTM-3 mine when triggered both under the bottom and under the chassis, regardless of the position of the mine on the ground surface.

It should also be noted that the PTM-3 anti-tank cumulative mine selected as a prototype ensures guaranteed destruction of all, including the most difficult to vulnerable tank units (engine, transmission, etc.) through an armor plate 20 mm thick. However, in the case of using promising tank bottom protection schemes that reduce its armor penetration, for example, in the form of spaced armor protection, the residual effect of a mine selected as a prototype becomes insufficient for hitting the propulsion system, which reduces the probability of hitting the tank by approximately 1.4 times.

To ensure the maximum destructive action of mines of this design on the tank’s track, it is necessary to increase the explosive charge mass, and also increase the area of its contact with the track, while ensuring the maximum possible mass of explosives (explosive) in it for a given dimension, the axial channel for placing the means mine initiation should also be minimal. However, too close the location of the initiators and detonating cords that transmit detonation from the fuse to these initiators, can lead to their initiation in the wrong order as necessary.

The well-known anti-tank mine of combined action PTM-3, designed for remote installation, has an elongated parallelepiped-shaped housing, therefore it has low companibility in cylindrical compartments in remote mining systems. The anti-tank cumulative mine PTM-3, due to its compact form, has a large steady landing speed. To ensure the strength of the mines of this design when falling onto the ground at such a speed, the mine body has an increased thickness, which leads to a heavier mine and a decrease in the payload of the remote mining system. In addition, when remotely installing the well-known anti-tank mine of combined PTM-3 action on soft soils, it is necessary to provide a rebound, which limits the modes of application of remote mining systems.

The technical result of the claimed invention is to increase the effectiveness of the anti-tank cumulative mines of a remote installation.

To achieve this goal (technical result), the applicant proposes the design of a cumulative anti-tank mine of a remote installation, characterized by the following set of essential features.

The claimed anti-tank cumulative mine of a remote installation has an elongated body made in the form of a half-cylinder, and its gutter-shaped cumulative lining is located on the flat part of the body and consists of two superimposed thin-walled claddings with a thickness of 0.01 ... 0.015 of the width of the cladding.

The firing device of the anti-tank cumulative mine of the remote installation further comprises a firing pin, an expelling charge and a pyrotechnic retarding ring with a retarding retarding track to initiate the aforementioned expelling charge.

The detonating cord transmitting detonation from the detonating device is connected at one end to the last (detonating device), and the other to the other detonating cord, transmitting detonation to the initiators from the previous detonating cord, at an angle of 90 ° in the place of their mutual contact, and the place mutual contact equidistant from the initiators.

The anti-tank cumulative mine of the remote installation is equipped with a folding orienting device-stabilizer in the form of a folding spring wire frame and placed on it around the perimeter of the flat part of the mine body, a detachable fabric cover, and the spring wire frame in turn contains two springs in the form of rectangular wire frames, lateral elongated the sides of which in the middle are twisted into cylindrical springs, the ends of these rectangular springs are pivotally attached to the mine body at its ends flat th part, and in the middle of the latter, a spring stop is fixed in the form of a rectangular wire frame bent in its plane along the cylinder.

The anti-tank cumulative mine of the remote installation contains a semi-cylindrical elongated body (1) with a gutter-shaped cumulative lining (2), an explosive charge (3), an explosive device (4) located at the end face (22) of the body (1), and initiation means, including two simultaneously triggering initiators (5) and (6), connected to each other and the fuse (4) by detonating cords (7) and (8), while one of the detonating cords (8) is connected to the fuse (4) at one end, and to others - to another child iruyuschemu cord (7), which in turn is attached at one end to one initiator (5), and the other - to the other initiator (6). Moreover, the detonating cords (7) and (8) are connected to each other at an angle of 90 ° in the place of their mutual contact (23), and the very place of their mutual contact (23) is equidistant from the initiators (5) and (6).

The elongated mine body (1) is made in the form of a half cylinder, the gutter-shaped cumulative lining (2) is located on the flat part (21) of the housing (1) and consists of two thin-walled facing (19) and (20) superimposed with a thickness of 0.01. ..0.015 of the width of the lining (2). An orienting device-stabilizer (24) is fixed on the flat part (21) of the housing (1), containing a folding spring wire frame (25) and a detachable fabric cover (9) fixed around the perimeter of the flat part of the mine housing (21).

The folding spring wire frame (25) consists of two springs (11) in the form of rectangular wire frames, the sides (26) and (27) in which are elongated and twisted in the middle into cylindrical springs (28), and their ends (29) are articulated (30) are attached to the flat part (21) of the housing (1) at its ends (22). In the middle of the flat part (21) of the mine body (1), a spring stop (10) is fixed in the form of a rectangular wire frame bent in its plane along the cylinder.

The detachable fabric cover (9) in the transverse and longitudinal sections has the shape of isosceles trapezoid (31) and (32), respectively, and both of its bases have the shape of rectangles, while the length of the upper narrow base (33) exceeds the length (35) of the body (1) mines, and the length of the lower base (34) of the cover (9) adjacent to the flat part (21) of the housing (1) does not exceed the length (35) of the housing (1) of the mine. The height of the detachable fabric cover (9) exceeds the radius of the half-cylinder of the mine body (1). A detachable fabric cover (9) is mounted on a folding spring wire frame (25) with a cable (14), held on one side by hooks (18) on the housing (1), and on the other hand, with a folding bracket (12) attached to the shooting pin ( 13) an explosive device (4) having an additional pyrotechnic retardation ring (15), made with a retardation retardation track (16), and a kick charge (17) is located between the retardation path (16) and the firing pin (13).

The inventive anti-tank cumulative mine remote installation operates as follows.

In the transport position, the anti-tank cumulative mine is placed in the cartridge, and its folding orienting stabilizer device (24) is held in a folded state. When an anti-tank mine is fired from a cassette mining system under the influence of powder gases of the expelling charge of the cartridge in which it is transported, the pyrotechnic retardation ring (15) is ignited in the fuse (4) and the mine itself is ejected from the cartridge in a given direction. After the anti-tank cumulative mine leaves the cartridge in free space, its orienting stabilizer device (24), which is previously folded, is released and is opened due to the elastic forces of the folding spring wire frame (25), taking the form shown in Fig. 1, 2, 8. In this case, the folding fabric cover (9) is straightened and, interacting with the incoming air flow, holds the mine body (1) in an oriented position, which provides intensive braking of the mine in the air, and a gutter-shaped kumu yativnaya facing (2) on the flat part (21) of the housing (1) is turned towards the upper hemisphere airspace. After falling to the ground and re-striking the mine, it is set on the ground in an oriented position with the cumulative lining (2) up due to the selected form of the orienting device (24) and the mine body (1), as well as the low center of gravity. Some time after the start of the burning of the pyrotechnic retardation ring (15), the retardation bypass path (16) lights up, setting fire to the expelling charge (17). Under the influence of the powder gases of the triggered out-charge (17), the pin (13) is fired, and then the hinged bracket (12) is released from engagement with the cable (14), after which, under the influence of the springs (11), the fabric cover (9) which, of course, increases the camouflage of anti-tank mines on the ground. After the retardation ring (15) is completely burnt, the explosive device (4) is put into combat position.

When a tank hits a mine, an explosive device (4) is triggered, and then detonation from it along the detonating cord (8) reaches the point of contact (23) equidistant from the initiators (5) and (6), and then along the detonating cord (7) transmitted simultaneously to initiators (5) and (6), which fire simultaneously, forming the direction of the detonation front, which ensures the optimal formation of a cumulative jet in the direction of the target. The cumulative jet that hits the bottom of the tank hits him. This is due to the fact that the inventive cumulative anti-tank mine has an elongated composite trough-like cladding, consisting of two superimposed thin-walled claddings with a thickness of 0.01 ... 0.015 of the width of the cladding, interconnected, for example, by spot welding, and also that the explosion of an explosive charge (BB) occurs as a result of the simultaneous operation of two initiators spaced in the longitudinal direction of the mine shell, which ensures the collapse of the cumulative lining in the longitudinal and across in the opposite directions with the formation of a cumulative jet and its shock-wave acceleration, which leads to a greater elongation of the damaging element compared to a single-layer cladding in the well-known PTM-3 mine (prototype). When a tank hits a mine with a caterpillar, a mine ensures its interruption due to the large contact surface.

In addition, the presence in the claimed anti-tank cumulative mine of one gutter-like lining instead of four, as in the well-known mine PTM-3, provides the maximum concentration of explosive energy of the explosive to defeat the tank, since the active mass of the explosive, oriented towards the target, and the area of contact of the explosive with the caterpillar of the tank in the claimed mine is significantly larger. Compared with the well-known anti-tank mine of combined action PTM-3 of the claimed anti-tank mine due to the use of the above distinguishing features, armor penetration is increased by approximately 1.5 times, which is confirmed experimentally, while the mass of the explosive charge is reduced by 20%, and the mass of the entire mine is reduced by thirty%. At the same time, it should be noted that the aforementioned increase in armor penetration by 1.5 times is possible only if it is installed on the ground in an oriented position, i.e. in a position in which the cumulative lining of the mine will be directed towards the target. This condition is provided due to the presence of the declared anti-tank cumulative mine orienting device-stabilizer (24).

The declared anti-tank cumulative mine for remote installation has fully developed the technical documentation. In accordance with this technical documentation, a batch of these anti-tank cumulative mines was manufactured and tested with positive results. The tests fully confirmed their increased armor penetration in cases of using promising tank bottom protection schemes and the sufficient probability of a tank caterpillar being killed, its reliable preservation and being installed on various soils in an oriented position after dumping in different modes from various mining systems, as well as maskability in the underlying vegetation.
