Description

The invention relates to engineering cluster anti-personnel munitions designed for remote mining of the terrain against manpower of the enemy.

Known cluster anti-personnel munitions designed for remote mining of the terrain with anti-personnel and anti-tank mines of a remote installation (Catalog "Jane a Minea and mine clearance. Editea by colin King / Edition 2002-2003").

Also known is a cartridge for remote mining, selected as a prototype (Patent for invention No. 2270975, application No. 2004110368, priority of invention 07.04.2004, registered in the State Register of Inventions of the Russian Federation on 02.27.2006, RU 2270975 C2, IPC F42B 12 / 58).

The known cartridge for remote mining contains a cylindrical cup, a cover, a piston with a knockout charge, an electric capsule and elongated semi-cylindrical anti-tank shaped-charge mines coaxial with it between the piston and the cover, coaxially aligned with it between the piston and the cover, on each flat side of which there is a spring-loaded folding the orienting device is a stabilizer, and an explosive device with a cocking element in the form of a thermobaric yes is installed on one of the ends of the cumulative mine sensor, with a mechanical protection step in the form of a spring-loaded stopper and a temporary electric-type self-destruction device connected to the contact pads on the fuse device body, and the piston has spring-loaded electrical contacts protruding beyond its dimensions, abutting the corresponding contact pads on the fuse device body and connected to the electrical connector mounted on the outside of the cover.

An analysis of the designs of the above-mentioned known cluster munitions for remote mining of the terrain shows that all of them do not provide the possibility of creating a highly effective minefield due to irrational dispersion of mines on the ground, since the mines placed in them have no stabilizers (cluster munitions with anti-personnel and anti-tank mines BLU-91 / B, BLU-92 / B, M67, M74, M75, USA, POM-1C, PTM-3, Russia, etc.) or they have, but their design is the same for all mines placed in the cartridge ( PTM-4, POM-2, Russia et al.), and the possible dispersion min terrain can be achieved and only climb airspeed suppressors.

Another significant drawback of the known cluster munitions for remote mining is either the lack of the ability to set the time for self-destruction before use (cluster munitions with mines POM-1C, POM-2, PTM-3, Russia, etc.), or the ability to set the time for self-destruction only with special programming devices before installing cluster munitions on a carrier (cluster munitions with mines M74, M75, USA, PTM-4, Russia, etc.), and not during the mining process, which significantly limits possibility of their use in various-layers (ground mine layers, helicopter mining systems, portable kits mining etc.).

The aim of this invention is to eliminate the disadvantages of both the prototype and the analogues, i.e. providing the possibility of creating, with a single minefield cassette, increased infantry operations efficiency, as well as its use in various mine loaders, such as ground mine loaders, helicopter mining systems, portable mining kits, etc.

To achieve this goal (technical result), a new design of a one-time cartridge for remote mining from aviation or ground-based miners is claimed. The proposed one-time cartridge contains a cylindrical glass with a lid. Inside the cup are a coaxial piston with a knock-out charge and a block containing two sections of cylindrical anti-personnel fragmentation mines fixed in it in pairs, a disk with separation charges divided into two parts, an inseparable disk, a coupling pin with a weakened section, pyrotechnic chains and an electrocapsule.

Moreover, in one of the sections of the block mines abut their ends on the one hand in the seats on the piston, and on the other - in the seats on one of the sides of the shared disk. In the other section of the block, mines abut with their ends on one side into the seats on the other side of the shared disk, and on the other into the seats on the undivided disk located at the outlet of the glass. Mines in the block are held by a coupling pin, one end of which is fixed in the piston, and the other in the inseparable disk.

Part of the mines in each section is equipped with stabilizers in flight in the form of parachutes, and the other in the form of fabric tapes covered with protective covers. In the seats of the shared disk, stops are installed that interact with the spring-loaded rods of mine fuses to remove the protection level, and electrical contacts that provide the fuse with the internal circuitry of the fuse to the manual self-destruct time switch with an autonomous power source mounted on the cassette lid, as well as to the control system of the trap using external electrical contacts located at the bottom of the cylindrical glass.

Mine fuses are equipped with thermobaric sensors oriented towards the separation charges and connected with the pyrotechnic chains of the cartridge through the corresponding gas holes in the shared disk.

The cavities of the expelling and separation charges are interconnected by gas tubes with pyrotechnic moderators and amplifiers, and in the shared disk to block the gas ducts there are nests with clamps, which have bevels at an angle of 45-70 degrees to the longitudinal axis of the corresponding gas tubes.

In figures 1 or 2 shows the device of the claimed design of a single cartridge for remote mining in its longitudinal and transverse sections, as well as a top view along arrow B.

Figure 3 (section A-A) shows the electrical contacts for connecting to the electric circuit of the fuse and gas holes in the shared disk, as well as the thermobaric sensors of anti-personnel fragmentation mine fuses.

Figure 4 shows an axonometric image of a block with anti-personnel fragmentation mines.

The figure 5 shows a dispersal diagram of anti-personnel fragmentation mines when firing a cartridge from a caterpillar mine layer.

A one-time cartridge for remote mining from aviation and ground-based miners contains a cylindrical cup 1, a cover 2, a piston 3, a knockout charge 4 and an electrocapsule 5. Inside the cylindrical cup 1, a block 6 is placed coaxially with it. In turn, the block 6 contains in pairs, two sections of cylindrical anti-personnel fragmentation mines 7 held by a piston 3, shared 8 and inseparable 9 disks with sockets 10 and a tie rod 11 having a weakened section 12.

In order to ensure the necessary dispersal of anti-personnel mines 7 in the minefield, the latter are equipped with pairwise stabilizers 13 in flight, with one half of the stabilizers in the form of nylon ribbons and the other in the form of parachutes closed by protective covers 14.

A switch 16 with an autonomous power supply for manually setting the self-destruction time of min. 7 is built into the lid 2 of the cassette, and external electrical contacts 17 are installed in the bottom of the glass 1 for connecting to the mining control system of the choke 29, in order to activate and set the self-destruction time of min 7 immediately before when mines 7 are inside a one-time cartridge. At the same time, the above-mentioned self-liquidation time setting circuits are connected to the electric circuit of the min 7 fuses using electrical contacts 17 located in the sockets 10 of the disk 8 that is shared by means of separation charges 20.

In the slots 10 of the shared disk 8 there are gas holes 18 used to activate the thermobaric sensors 19 in the min 7 fuses, and between the two parts of the shared disk 8, opposite the gas holes 18, separation charges 20 are connected, connected by the gas pipes 21 with pyrotechnic amplifiers 22, moderators 23, located at the ends of the tubes 21 adjacent to the piston 3. The gas pipes 21 have a housing 24.

To remove the mechanical stage of protection in the slots 10 of both parts of the shared disk 8 there are stops 25, interacting with spring-loaded rods 26, placed in fuses min 7.

To overlap the gas holes 18 in the cross section of one of the parts of the shared disk 8, sockets with safety latches 27 are made, having bevels 28 at an angle of 45-70 degrees to the longitudinal axis of the corresponding gas pipe 21.

The action of the inventive one-time cartridge for remote anti-personnel mining is as follows.

Before using a one-time cartridge, the required self-destruction time of min 7 is set either manually using the switches 15 on the cover 2 and the electrical contacts 17, or through external electrical contacts 16 and electrical contacts 17 from the mining control system 29.

After that, an electrical impulse is supplied from the trap to trigger the electrocapsule 5, which ignites the expelling charge 4.

Under the influence of powder gases of the knockout charge 4, the block 6 is fired with anti-personnel fragmentation mines fixed in it in two sections 7. At the same time, the pyrotechnic moderator 23 is set on fire, while the deceleration time is selected so that the unpacking of block 6 with mines 7 occurs at the required distance and altitude for remote installation of a minefield.

After burning of the pyrotechnic moderator 23, the pyrotechnic amplifier 22 is ignited, while under the influence of their powder gases on the bevels 28, the latches 27, moving, release the passage between the gas holes 18 in the shared disk 8 and the outlet holes of the gas pipes 21. The separation charges 20 are ignited and triggered rupture of the tie rod 11 along the weakened section 12.

Further, the triggered separation charges 20 through the gas holes 18 activate the thermobaric sensors 19 in the min 7 fuses. The block 6 with the shared disk 8 breaks up into components, while the protective covers 14 fly off, the mines 7 exit from the nests 10, the spring-loaded rods 26 come out of the stops 25, removing the mechanical stage of protection in mine fuses 7. Under the influence of the oncoming air stream, stabilizers 13 are opened in the form of kapron belts or parachutes, and the mines are scattered along their flight path to the ground.

After the set time for self-destruction has expired, the minefield will self-destruct, which ensures compliance with the requirements of the amended Protocol II of the Geneva Convention to ban or limit the use of anti-personnel mines.
