THROWING.

The utility model relates to the ammunition for upoTMHOiiexoTHHx automatic and multi-barrel hand-held rocket launchers, and more specifically, to the missile charges of the fragmentation-friendly ammunition.

The state of the art is characterized by artillery cartridges for an automatic grenade launcher containing a warhead with leading loyalty and a propelling charge, including 1 cartridge. filled with pea, and an igniter capsule (see, for example, patents RU 2135938, F 42В 5/18 and 2125226, F 42В 5/02, both 1999),

These cartridges differ in that the propellant charge is placed in a C1oranium camera equipped with a receiver, made in the form of a sleeve 5, which is permanently attached to the shank of the warhead body and acts as a sleeve.

The end of the combustion chamber filled with gunpowder is closed by a horizontal perforated diaphragm 1, on which a metal membrane is fixed, separating it from the receiver and holding the powder charge,

EFFECT: inventions make it possible to unify the production of shellless cartridges 5 to reduce operating costs by eliminating the collection of hot shells in boxes in limited volumes of grenade launcher carriers (armored personnel carriers, helicopters, etc.) or the use of up to 1 additional reflective devices to remove cartridges from the firing zone.

In this case:} the energy of the propellant charge is not expended on unscathed.

However, a drawback of the listed advantages of artillery cartridges is the disadvantage in that the structural elements of the propelled charge transported to the target are a massive ballast for the main combat action of a high-explosive fragmentation warhead.

In addition to Toio, the free installation of a metal membrane on the diaphragm, or with the possibility of relative movement during operation, requires additional measures and means for sealing the volume of the chamber in order to guarantee the isolation of gunpowder from atmospheric moisture during storage of cartridges, which increases the loss of b a tel s to u with t about and m about with t products.

The noted drawbacks are eliminated in the artillery cartridge for patent RU 2087837, F 42В 5/02, 1997, chosen but the technical essence and the number of matching features as the closest Koio aHajioia, which contains fragmentation grenade and propellant charge 5 including 1 canister with gunpowder, over which IopMzonal perforated diaphragm-1 was installed with sealing 1rock. 1 joints on both surfaces, which are i-geometrically closed around the perimeter of the sleeve material by means of a bent edge of the annular notch of the ledge.

A grenade is installed on the ledge, which hermetically fixes the diaphragm with pro-1 attachments in the body of the cartridge case, in the elongated part of which longitudinal technological grooves are made for the air to exit when assembling the warhead with the i-cartridge. The volume of the i-cartridge between the end face of the grenade and the diaphragm forms a receiver for powder gases with func tions and functions.

Both good. (membranes) mounted on the diaphragm are made of 0.05 mm thick aluminum foil and are completely burnt in powder tubes before the grenade begins to move along the CTBOJIH channel,

The assembly of the diaphragm covered with gaskets with an i-sleeve is carried out automatically and is considered to be a punching tool, without completion operations.

There is evidence of the tightness of the onis-known Aamco junction.

The achieved Iraqi identity of the initial speeds of propelled grenades confirms the stability of the 1-azodynamic regimes during the generation of gunpowder in the propelled aaryad, the sleeve of which 1-0 is fixed by crimping the muzzle into the sunset groove of the grenade body. However, aluminum gaskets are ignited when interacting with the products of the eradication of gunpowder under conditions of negative oxygen balance and completely burn out, significantly increasing the temperature of the working mixture, which leads to the formation of flame combustion, the muzzle and especially reverse flame from the interaction of aluminum with carbon dioxide and atmospheric water the air is blinded by the shooter and unmasked by the eiO at the battlefield position, which is a significant functional disadvantage of a well-known charge.

The mechanical connection of metal structural elements is good. The tone in the lock connection is propellant about the charge ensures stability of the ballistic characteristics of the grenade being thrown, but it is conditionally sealed 5 because there are capillaries, pores and microcracks in the contact points that absorb atmospheric moisture, which gradually penetrates the powder. Consequently, moisture insulation in a known propellant charge during long-term storage and transportation is unsatisfactory and can serve as a cause. Functionality. l n x patron on, that is not up to usstim about.

The objective underlying this useful model is to increase the functional reliability of a known propellant by eliminating flames during firing and ensuring guaranteed moisture insulation of gunpowder during long-term autonomous storage and transportation of propellant bombs, unified under different warheads.

laminator and IMJibay with a ring ledge inside which is mounted above the gas filling of the combustion chamber | oriminal diaphragm, top-sealed gasket, geometrically apertured along the perimeter of the annular side edge of the shoulder notch, | the cartridge boom is lined and glued to the diaphragm.

Distinctive features provide throwing aarndue increased functional reliability aa due to the guaranteed 1 leakproofness of gunpowder filling of the guillah during autonomous long-term storage and transportation to the assembly place with combat parts of the rolling structures, as well as flameless burning during firing, because atron paper does not burn under negative conditions the oxygen balance of redox reactions and acts as an inhibitor, reducing the temperature of powder gaaov.

The unification of the throwing aaryad extends the technological capabilities of the eio application to the end, guaranteed to receive the required calculated throwing momentum during the combustion of the cyxoio iiopoxoBoro filling, which is ensured by aaaaaoran gluing of the paper pad to the diaphragm of the aamkovo1-o connection with the guilla material.

The polar model allowed us to exclude aa unnecessary for a 1-seal design and a sealing aluminum gasket on the lower surface of the diaphragm facing the combustion chamber of theoxoBoiO i-filling, which simplified the assembly of the propellant

The sealing gasket of cartridge paper emits an additional function when the propellant is triggered: lowering the temperature of the powder i-aaov and thereby preventing part 1 of the invention.

Consequently, each essential sign is necessary, and their coherence in a stable relationship is sufficient to achieve a novelty of quality that is not inherent in signs of disunity. The essence of a useful fashion. 11 And is illustrated by a drawing, which has purely illustrative purposes and does not limit the scope of the rights of the formula, 1de depicted:

-on the . 3-6 - technological transitions from the manufacture of the castle connection, next. All: initial position, installation of the diaphragm with glued gasket, notch ledge and flanging.

A fragmentation grenade 1 (Fig. 1) with a fuse 2 and an Ion lead 3 mounted on a ledge 4 of the wall of the sleeve 5. In the bottom of the body of the grenade 1, below the sunset groove 6, 1 longitudinal grooves 7 are made.

On 1st March 5, the charge (phi1-, 2) is mounted: ignite the capsule. 8, powder filling 9 and perforated diaphragm 1 10 is horizontal, on which a 0.1 mm thick sealing gasket 11 is made glueless on top, made of cartridge paper A according to GOST 8 76-73, impregnated with varnish with a flame retardant, an active flame arrester that reduces the temperature of powder gases,

In the diaphragm 10, calibrated holes 12 are made — perforations through which the powder i-elements enter the receiver 13 (fi 1), formed by the volume of the sleeve 5 with the height of the ledge 4, that is, over the gasket 11 to the end of the i-wound body 1.

Composition: a diaphragm U-gasket ii with guilty 5 is knitted by means of a lock. 1 connection, which is formed by a stratoium and with a tricymene and a j of sizing.

On the k-ring ledge 4 in the wall of 1st-4th-5th (Fig. 3), made at the level nopoxoBoio of filling 9 of the camera C1orania, the diaphragm AMU is installed. 10 with a pre-glued y, tighten the flax and about to and to and to 11 (Fig. 4).

Then, the material of the ledge 4 is subjected to an annular notch (ph1.5), forming an annular flange 14, which then from the end of the stop to the diaphragm 10 through the gasket 11 (ph1.6), making a geometric and force closure, i.e. 1 tightly fixes in the body of the sleeve 5.

Next, the grenade 1 for press fit is installed on the ledge 4 of the sleeve 5; in this case, compressible air through the grooves 7 and b is removed from it, 1 pressing the gasket 11 against the diaphragm 10, preserving the integrity of the composition and the tightness of the chamber C1 of the i-cartridge 5, where gunpowder 9 is located.

By compressing the barrel of the sleeve 5 into the sunset groove 6, the grenade body 1 is fixed - the cartridge is assembled and ready for use. The volume of the sleeve 5 between the bottom slice of the grenade 1 and the gasket 11 of the diaphragm-10 forms a receiver 13 (figL).

The propellant charge according to the proposed utility model is a self-contained autonomous unit of artillery ammunition compatible with warheads of various designs, therefore it can be stored separately until assembly with the required shells, while maintaining the basic technical characteristics of the reliably insulated nopoxoBoio filling 9 for a long time.

12 of the diaphragm 10, and then selects it into the receiver 13, 1 where it is heated and intermixed.

In the receiver 13 C1, the inevitable pressure fluctuations and transition process of the onset of combustion begin to be found, and the temperature of the powder gases is reduced by the action of iroclad material 11, which does not ionize under negative oxygen balance, but acts as an anti-irene, preventing the fiery burning of gunpowder 9.

Under the influence of the pressure of the powder gases, there is a separation of the cartridge case 5 with a grenade 1, which moves further but to the barrel 1 of the rocket launcher 5 rotating but screwed by means of a leading tongue 3,

Tests by shooting experimental products showed an almost complete absence of both a muzzle-1-O5 and vice versa-1 flame.

Gunpowder 9 of a propellant charge after modeling climate tests for a long period of autonomous storage remained dry, in the initial state, which confirms the reliability of the proposed design of the hermetic insulation of the combustion chamber of propellant propellant charge, which provides stable projectile characteristics to the projectile,

A comparative analysis of the proposed propellant charge with the identified analogues of the prior art does not explicitly follow from KOTopoio for an ammunition specialist, showed that it is not known, and considering the possibility of industrial serial reproduction 5, it can be concluded that the criteria are met about 11 about with about n about with t and.
