Description

The invention relates to ammunition, and more specifically to disposable cassettes for remote mining of terrain with multi-purpose mines.

Known cassettes for remote installation of anti-tank mines: KPTM-3 (Cassette warhead with anti-tank mines PTM-3, catalog “Weapons of Russia”, volume VII, “High-precision weapons and ammunition”, JSC “Military Parade” M., - 1997. , pp. 119-120), KPTM-4 with anti-tank mines PTM-4 patent for invention No. 2270975, application No. 2004110368, priority of invention 04/07/2004

Also known are cassettes for remote installation of anti-personnel mines: KPOM-2 with anti-personnel fragmentation mines POM-2 (catalog “Janes mines and mine clearance”, Edited by Colin King, Jans Information Group Inc,) 340 Braddoc Place, Suite 300, Alexandria, Virginia , USA, issue 1996-1997, p. 395), KPOM-3 (prototype) with anti-personnel fragmentation mines POM-3 patent for invention No. 2429445, application No. 2010101364, priority of invention 01/18/20)0, registered in State Register of Inventions of the Russian Federation 09.20.2011, RU 2429445 C1.

The known disposable cassette for remote mining KPOM-3 contains a cylindrical glass with a lid, inside of which there is a piston with an expulsion charge and a block containing two sections of cylindrical anti-personnel fragmentation mines fixed in it, a disk with separating charges that can be divided into two parts, and a non-separable disk. , a tie rod with a weakened cross-section, pyrotechnic chains, a switch for manually setting the self-destruction time, an electric capsule and electrical contacts that, using internal wiring, provide connection to the electrical circuit of the fuses, a switch for manually setting the self-destruction time of mines with an autonomous power source, mounted on the cassette cover, and also - to the minelayer control system using external electrical contacts located at the bottom of the cylindrical glass.

In one of the sections of the block, the mines rest with their ends on one side against the seats on the piston, and on the other, against the seats on one of the sides of the divided disk; in the other section of the block, the mines rest with their ends on one side against the seats on the other sides of the separable disk, and on the other - into seats on the non-separable disk, located at the outlet of the glass, and are held by a tie rod, one end of which is fixed in the piston, and the other in the non-separable disk.

The above-mentioned known cassettes have a number of disadvantages, for example, for the installation of mixed minefields against enemy personnel and armored vehicles, cassettes with anti-personnel etc. are required separately. separately, cassettes with anti-tank mines, which increases the range of cassettes and increases the cost of installing mixed minefields. In addition, in the above cassettes, mines are released at only one speed. Considering that the distance between mines on the ground, installed from one cassette, depends, in particular, on the time of exposure to the air flow, in order to obtain minefields installed from aircraft carriers from the above cassettes with a density close to uniform, it is necessary to significantly increase the flight altitude of the carrier , which is not always possible and safe.

The purpose of this invention is to eliminate the above disadvantages of both the prototype and analogues, i.e. ensuring the possibility of creating, using a disposable cassette for remote mining, a minefield of increased effectiveness against enemy infantry and armored vehicles, including from low flight altitudes of an aircraft carrier, through the use of a dual-mode ejection of a block with mines from the cassette

To achieve the set goal (technical result), a new design of a disposable cassette for remote mining is claimed, which contains a cylindrical glass with a block for setting the self-destruction time, inside of which there is located coaxially with it a piston with an expelling charge and a block containing two sections of multi-purpose mines fixed in it, separable into two parts a disk with separating charges, a block for setting the self-destruction time, buttons for selecting and manually setting the self-destruction time, built into the block for setting the self-destruction time, pyrotechnic circuits, an electric capsule and electrical contacts for connecting mines to the minelayer's mining control system and for manually setting the self-destruction time of mines, with In this case, in one of the sections of the block, the mines rest with their ends on one side against the seats on the piston, and on the other, against the seats on one side of the divided disk; in the other section of the block, the mines rest with their ends on one side against the seats on the other from the sides of the divided disk, and on the other - into the seats on the self-liquidation time setting unit located at the outlet of the glass. In the center of the cylindrical glass there is a gas duct tube, consisting of two parts connected to each other by a burst sleeve. The mines in the sections of the block are held by a central gas pipe, one end of which is fixed in the piston, and the other in the block for setting the self-destruction time of the mines. In the seats of the separable disk, guides are installed that interact with spring-loaded rods to remove the mechanical mine protection stage, and electrical connectors that, using internal wiring, provide connection of mines to the minelayer's mining control system using external electrical contacts located at the bottom of the cylindrical cup and for manually setting the self-destruction time min using buttons for selecting and setting the self-liquidation time, built into the unit for setting the self-liquidation time of the cassette for convenience. The internal electrical wiring harnesses are installed tightly into the grooves of the external contour of the separating disk using polyamide tension bushings, which contribute to the rupture of the harnesses in the central part. Buttons for selecting and setting the self-destruction time of mines in manual mode are built into the unit for setting the mine self-destruction time in manual mode for ease of use, located at the outlet of the cylindrical glass. The piston with the expelling charge has a central through hole in the center, which ensures the cocking of an additional powder charge placed in the gas duct after the expelling charge in the piston is ignited. There is a plug installed at the other end of the gas pipe. When removing the plug from the tube before use, when the expelling charge is ignited, some of the gases from the piston tube of the gas pipe 9, 10 reduce the rate of mine ejection from the cassette by approximately two times compared to the second mode (threaded plug 13 is not unscrewed).

In the second throwing mode with a closed plug 13, after igniting the powder sample 12 in the gas pipe 9, 10, the powder gases return to the piston volume, increasing the pressure on the piston and thereby increasing the emission rate of min.

At the same time, after the moderator 23 burns through a given deceleration time, the powder gases through the gas-duct tube of the moderator 22 ignite the separating charges 21, the separating charges are triggered and the bursting sleeve connecting both parts of the gas-duct tube ruptures, as well as the internal electrical wiring harnesses 19 in the central part rupture , which ensures uniform unpacking of the block when dividing into two parts of the shared disk 8.

Next, the triggered separating charges 21 activate the temperature and pressure sensors in the mine fuses 7. Block 6 with the separable disk 8 disintegrates into its component parts, while the protective casings 15 fly off, the mines come out of the sockets of the disk 8, piston 3 and the self-destruct time setting unit 2. Under the influence of the incoming air flow, the stabilizers open in the form of parachutes and the mines are scattered along the trajectory of their flight to the ground.

After the established self-destruction time, the minefield (anti-tank, anti-personnel) self-destructs, which ensures compliance with the requirements of the amended Protocol II of the Geneva Convention on the Prohibition or Restriction of the Use of Anti-Personnel Mines in relation to the anti-personnel minefield.

volumes formed when the expelling charge is ignited and the gases formed when the powder sample placed in the gas duct is ignited are released through the tube and mines are ejected from the cassette at a reduced speed, which increases the distance on the ground between mines installed from one cassette from a low altitude aircraft flight carrier by increasing the time of exposure of the air flow to the mines. If the tube is closed with a stopper, then when the powder sample in the gas pipe is ignited, the resulting gases knock out the sleeve with a calibrated hole and fill the piston volume, which leads to an increase in pressure in the piston volume and to an increase in the speed of ejection of the block with mines from the cassette, which is recommended for use on large flight altitudes of the aircraft carrier. The gas duct tube consists of two parts connected by a burst sleeve, which is destroyed when the separating charge in the separated disk is ignited and provides a boost force when arming mines at the time of unpacking the block with mines.

A disposable cassette for remote mining contains a cylindrical glass 1, a self-liquidation time setting unit 2, a piston 3, an expelling charge 4 and an electric capsule 5. Inside the cylindrical glass 1, a block 6 is placed coaxially with it. In turn, block 6 contains pairs fixed in it. two sections of cylindrical multi-purpose mines 7, held by a piston 3, a separable disk 8, a self-liquidation time setting unit 2 and a gas duct tube, consisting of two parts 9, 10, which are connected by a bursting sleeve 11. Inside the gas duct tube there is a powder sample 12 and a felt wad 23. At one end of the gas duct tube there is a threaded plug 13, at the other end there is a sleeve with a calibrated hole 14. All multi-purpose mines 7 are equipped with stabilizers in the form of parachutes, closed with protective covers 15. The self-destruction time setting unit 2 has built-in selection buttons 16 and time setting buttons 17 self-destruction of mines 7, and in the bottom of cup 1 external electrical contacts 18 are installed for connection to the minelayer's mining control system in order to activate and set the self-destruction time of mines 7 immediately before use, when mines 7 are inside a disposable cassette. Wiring harnesses 19 for connecting mines to the minelayer's mining control system and for manually setting the self-destruction time of the mines are installed tightly using a bushing 20 into the grooves of the external contour of the separable disk 8. Gas pipes 22 are installed opposite the separating charges 21, the ends of which are fixed in the piston 3 using a threaded connections under the moderators 23 installed in the piston 3. The threaded connection of the tube 22 with the piston 3 is provided for ease of assembly of the cassette.

The operation of the inventive disposable cassette for remote mixed mining occurs as follows.

Before using a disposable cassette for remote mining, the required self-destruction time of mine 7 is set either manually using the controls of the UVS unit 2 (installation buttons 15 and selection 16 of the self-destruction time), or through external electrical contacts 18 from the mining control system of the minelayer.

If the self-destruction time is not entered, then, in order to ensure the safety and storage of the cassettes, the mines are not transferred to the firing position after being ejected from the cassette.

After this, an electrical impulse is supplied from the minelayer to trigger the electric capsule 5, which ignites the expelling charge 4. Under the influence of the powder gases of the expelling charge 4 in the piston volume on the piston 3, the shooting of block 6 with multi-purpose mines 7 fixed in it in two sections begins. At the same time, they are set on fire moderator 23 and powder charge in the gas pipe 12 through a calibrated hole in the bushing)4. In this case, the size of the calibrated hole in the first mode of throwing mines from a cassette with the screw plug 13 unscrewed ensures the prescribed bleeding of gases in the piston volume and from the powder sample 12 through
