Description

The invention relates to ammunition, and more particularly to cartridges for remote mining of the area with cumulative anti-tank mines.

Known cartridges for the remote installation of engineering mines (Cassette warhead with mines PTM-3, the catalog "Arms of Russia", Volume VII, "High-precision weapons and ammunition", AOZT "Military Parade" M., - 1997, p. 119- 120).

Also known are cartridges for remote mining KPOM-2 (prototype), containing elongated mines with pressure and temperature sensors (with thermobaric sensors) located in a cylindrical glass between a piston with an expelling charge and a cover (Jane''s mines and mine clearance catalog ", Edited by Colin King, Jane's Information Group Inc, 1340 Braddock Place, Suite 300, Alexandria, Virginia, USA, 1996-1997, p. 395).

The aforementioned known cartridges have a number of disadvantages, for example, safety is not ensured when installing mines from a vehicle in a mining zone, since the deployment of mine fuses in them (cartridges) occurs after thermobaric sensors are triggered, that is, during the discharge of mines from a glass. In case of absence or incomplete exit of mines from the glass for some reason, for example, due to premature release of the pressure of the powder gases of the expelling charge, the mines with cocked fuses remain in the glass placed on the vehicle and can work unauthorized.

The distribution of mines on the ground when installing minefields from known cartridges occurs due to their technical dispersion by an incoming air stream. The distance between mines installed from the same cartridge depends, in particular, on the time of exposure to air flow. To obtain minefields installed from aircraft carriers with a density close to uniform, it is necessary to significantly increase the flight height of the carrier, which is not always possible and safe.

In the known cartridges for remote mining, there is no possibility of regulating the technical characteristics of the mines, for example, self-destruction time, without disassembling the cartridges, which significantly reduces the effectiveness of the established mine fields.

The invention is aimed at eliminating the above disadvantages of both the prototype and analogues, that is, the purpose of the invention is to increase the efficiency of minefields and to ensure the safety of the work associated with remote mining.

To achieve the technical result, a new design of the cartridge for remote mining is proposed, which includes a cylindrical cup, a cover, a piston with an expelling charge, an electric capsule and elongated semi-cylindrical anti-tank cumulative mines coaxial with it between the piston and the cover, fixedly aligned in a row inside the cylindrical cup. on the flat side of each of which a folding spring-loaded orienting device-stabilizer is fixed, and on one of the ends of the cumulative ins installed detonation device with a cocking element thermobaric sensor stage mechanical protection in the form of a spring-loaded detent device and a time of self-destruction of the electric type, connected to contact pads on detonation device housing. Unlike the prototype, in the inventive cartridge, cumulative anti-tank mines are oriented one to the other with their flat sides with a gap between the latter, providing the possibility of mutual tightening of the folding spring-loaded orienting stabilizer devices fixed on these flat sides, between the spring-loaded stoppers of the mechanical stage of protection of the fuse and the glass wall are installed without radial clearances, split ring segments holding these spring-loaded stoppers in the original m pressed up to the exit of mines from the cylindrical glass, while at the ends of the above segments of the split ring technological grooves are made for installation in them at the time of assembly of the device for remote mining of fork-shaped technological checks protruding beyond the dimensions of the glass after fixing them in the technological grooves of the segments of the split ring and in the piston spring-loaded electrical contacts protruding beyond its dimensions are installed, abutting against the corresponding contact pads on the housing zryvatelnogo device and connected to the electrical connector installed on the outside of the lid.

Figure 1 shows a longitudinal section of a cartridge for remote mining. Figure 2 - in an enlarged view of the contact pads on the housing of the fuse and interacting with them spring-loaded electrical contacts installed in the piston. Figure 3 is a cross-section of the segments of the split ring, placed between the wall of the cylindrical glass and a spring-loaded stopper cocking explosive device. Figures 4 and 5 show segments of a split ring with technological grooves and fork-shaped technological checks fixed in these grooves.

The cassette for remote mining consists of a cylindrical glass (1), in the bottom of which there is an electrocapsule (2). A piston (3) and a cap (5) are placed inside the cylindrical cup (1). Between the cover (5) and the piston (3) anti-tank cumulative mines (6) are placed. Cumulative anti-tank mines (6) have an elongated semi-cylindrical body, on the flat side (13) of each of which a spring-loaded orienting stabilizer device (10) is fixed, and at one of its ends there is an explosive device (17). Mines (6) are oriented inside the cylindrical glass (1) with explosive devices (17) towards the piston (3), and the flat sides (13) are one to the other, while the gap between the flat sides (13) is selected from the condition of ensuring the compression of both folding spring-loaded orienting stabilizer devices (10) to each other within its elasticity. On one side of the piston (3) there is a blow-out charge (4), and on the other hand, spring-loaded electrical contacts (14) protruding beyond its dimensions. An electrical connector (12) is installed on the outer side of the top cover (5), connected respectively by a wire line to the spring-loaded electrical contacts (14) of the piston (3), and the latter, in turn, abut against the corresponding contact pads (15) on the fuse case (17) . The contact pads (15) are connected to a temporary self-liquidating device of an electrical type located inside the fuse (17), which allows changing the time of self-liquidation by supplying it with the appropriate electrical signals. This ensures, if necessary, the possibility of changing the time of self-destruction of anti-tank cumulative mines (6) immediately before their installation by connecting to the electrical connector (12) an appropriate external device that allows you to change the time of self-destruction of mines (6). Explosive devices (17) are equipped with a cocking element in the form of a thermobaric sensor (7) and a mechanical protection stage in the form of a spring-loaded stopper (8). To ensure the possibility of the influence of powder gases on the thermobaric sensor (7), through channels (18) are made in the piston (3). Between the wall of the cylindrical glass (1) and the spring-loaded cocking stoppers (8) of the explosive devices (17), segments of the split ring (9) are placed without a gap. Due to the mechanical connection of the spring-loaded cocking stoppers (8) with the sectors of the split ring (9), it is possible to move them together inside the cylindrical glass (1), which excludes any possibility of cocking the explosive device (17) before the mines (6) go beyond cylindrical glass (1). The assembled cassette for remote mining is held by a destructible connection in the form of a crimp (19) of the upper edge of the cylindrical glass (1).

Figures 4 and 5 show a cartridge for remote mining during the installation of mines (6) in a cylindrical glass (1). Fork-shaped technological checks pre-installed in grooves (11), connecting two adjacent separate segments into a split ring (9), have dimensions that exceed the diameter of the cylindrical glass (1), therefore, when mines (6) are installed in the glass (1), the fork-shaped the checks (16) after the split ring (9) completely enters the inner cavity of the glass (1), naturally rests on its end and due to this stop will automatically be removed, after which the hard stop of the spring-loaded cocking stop (8) into the wall cylindrical glass (1) will be provided through the split ring segments (9).

Cassette for remote mining works as follows. When the expulsion charge (4) is triggered, the generated powder gases act on the piston (3) and through the through channels (18) on the thermobaric sensors (7). Under the influence of excess pressure of the powder gases, thermobaric sensors (7) are triggered and explosive devices (17) are charged. At the same time, excessive pressure of the powder gases destroys the crimp (19), thereby expelling the contents of the cylindrical glass (1) to the outside. After the mines (6) together with the segments of the split ring (9) go beyond the cylindrical cup (1), the split ring (9) is divided into its constituent segments, and after that the spring-loaded cocking stoppers (8) are released. Due to the release of the spring-loaded stoppers (8), the mechanical stage of protection of the explosive device (17) will be removed and the mines will go into working condition.

During the exit of anti-tank mines (6) from the cylindrical cup (1), the radial movement of mines (6) is removed, therefore, the folding spring-loaded orienting stabilizer devices (10) open and go into working condition, giving the mines (6) a radial velocity component and simultaneously increase the fall time of mines (6) on the ground, which together increases the distance between mines (6) pushed out of the same cylindrical glass (1) after they land on the ground, and as a result increases uniformity minefield.

If necessary, before triggering the expelling charge (4), using an external device connected to the electrical connector (12), it is possible to change the self-liquidation time min (6), pre-set at the factory, by applying the appropriate electrical pulses.

Based on the foregoing, it follows that the claimed invention allows to eliminate the above disadvantages of both the prototype and analogues, that is, to increase the efficiency of minefields due to the uniform distribution of anti-tank cumulative mines in the mining zone, as well as the possibility of adjusting the time required for self-destruction and safety ongoing work related to remote mining.
