Description

The invention relates to cartridges with smoke grenades for grenade launchers used by power structures for setting tactical smoke screens, target designation and "smoking" of the enemy from various premises.

Well-known ammunition with fumes in the form of operation of the latter on the target are divided into smokers and explosives.

An example of the former may be the Austrian Smoke 93 smoke cartridge described in the “Jane's Ammunition Handbook”, 2000-2001 on page 20 and adopted in for the present invention.

This cartridge is used for setting tactical smoke screens and includes a sleeve and grenade with a belt. The grenade consists of a durable metal case with a bottom in which a fuse in the form of a moderator is fixed for 1 s. The analogue smoke charge is formed by red phosphorus, pressed into the grenade body with the formation of end-burning checkers in it for 20 s. Products of combustion of a smoke charge (aerosol) flow into the atmosphere hole in the moderator.

The disadvantages include:

- a large unproductive consumption of the smoke charge when firing at the maximum (400 m) and close to it range, when the flight time of the grenade is equal to or close to half the combustion of the smoke charge;

- the ability to ricochet the grenade from the point of its fall and, consequently, set the curtain at some, sometimes significant, distance from this point;

- a long time for the formation of an invisible smoke screen due to the small surface and a sufficiently low burning rate of the smoke composition;

- low efficiency of firing at the enemy in the room, since the enemy, due to this drawback, has the ability to throw a grenade out before the formation of intolerable conditions in the room;

- a large passive weight of the grenade due to the need to have an undeformable body when it meets a solid obstacle.

From this it follows that the analogue cannot be used for target designation and the fight against the enemy indoors, and its use for setting tactical smoke screens involves the consumption of cartridges.

The disadvantages of the analogue are partially eliminated in another S418 smoke cartridge manufactured in Singapore, described in the Jane's Ammunition Handbook, 2000-2001 on page 22 and adopted as a prototype for the present invention.

The prototype has a two-chamber sleeve and a smoke grenade with a metal casing, which consists of a front part and a bottom, which is attached to it and attached to it, attached to it by a bond that is destroyed during a shot. The head fuse, a small explosive and smoke charge formed by red phosphorus, pressed into the body are placed in the body. When a grenade fires at a target, the detonator detonator and explosive charge destroy the front of its body and the smoke bomb and scatter the burning pieces of the latter.

Typically, the prototype is used as a marker in conjunction with other intended cartridges, i.e. It can be used for target designation and the fight against the enemy placed in the premises. It also compares favorably with its counterpart when setting tactical smoke screens, since its grenade fires at the point of incidence without a rebound, but due to the short burning time of pieces of its smoke charge, it creates only a separate aerosol cloud with a short lifetime, which requires a large consumption of cartridges to create an invisible smoke screen for a long time. In addition, the prototype grenade has a lower passive weight, since less rigid strength requirements are imposed on its body: it can significantly deform until the fuse detonates. However, such a case for its destruction requires the presence of a discontinuous charge in the grenade, which complicates its design.

The technical task of the present invention is to eliminate the disadvantages of the known smoke cartridges, namely, giving one specific cartridge the ability to highly efficiently solve the tasks of target designation, setting tactical smoke screens and combating the enemy in various types of rooms, while reducing the passive weight of his grenade and simplifying its design .

According to the present invention, the achievement of the technical task is ensured by the fact that in a cartridge containing a sleeve and fastened with a smoke grenade, which is destroyed when fired by a shot, including a body with a leading girdle, consisting of a front hollow part and a bottom fastened with it, a smoke charge of red phosphorus, pressed into the body, and fuse, new is that:

- the front of the case is molded thin-walled from plastic;

- the bottom of the body is also molded from plastic in the form of a thin-walled glass with the leading girdle and local diametrical lowering molded on it at the open end, by which it is glued to the front of the body;

- the smoke charge is pressed separately into the front of the casing and into its bottom, in each part of the smoke charge coaxially deaf cavities are formed in which the fuse is mounted;

- perforated gaskets glued to each other are glued to the ends of the parts of the smoke charge around the fuse, in which the bridges between the holes in the circumferential direction are smaller than the dimensions of these holes in the same direction.

The essence of the invention is illustrated by drawings, in which Fig. 1 shows a cartridge with a smoke grenade in a longitudinal section, in Fig. 2 - a cartridge grenade in a longitudinal section after the fuse is fired on a target, and Fig. 3 shows a perforated gasket.

The cartridge contains:

- sleeve 1;

- grenade 2, bonded to the sleeve with glue;

- the front hollow part 3 of the body of the grenade 2, molded thin-walled of plastic;

- the bottom 4 of the body of the grenade 2, molded from plastic in the form of a thin-walled cup, on which the leading belt 5 and the local diametrical lowering 6 are formed, with which the bottom of the body is glued to its front part;

- a smoke charge of red phosphorus, consisting of two parts 7 and 8, pressed into part 3 of the grenade body and into its bottom 4, respectively;

- coaxial blind end cavities 9 and 10, molded respectively in parts 7 and 8 of the smoke charge, in which the fuse 11 is mounted on the adhesive;

- identical perforated gaskets 12 glued to the ends of the smoke charge parts 7 and 8 around the fuse 11, glued together during assembly of the grenade and having jumpers between their neighboring holes 13, smaller in the circumferential direction than the size of these holes in the same direction. This embodiment of the holes in the gaskets is guaranteed to provide without special orientation to each other both parts of the smoke charge during the assembly of the grenade through passage channels between them through the holes 13 of the perforation.

Pressing the parts of the smoke charge into both thin-walled and grenade-forming parts of the grenade (the front part of the body and its bottom) provides, on the one hand, the grenade's necessary strength when fired, and on the other hand, the guaranteed destruction of the front part of the body and the part of the smoke charge inside it up to the level of the fuse end located in it (see Fig. 2), ignition of the fragmented parts of the smoke charge and their spread over the area under the influence of the energies of impact of the grenade with the target surface and the detonator detonator explosion. In this case, as practice shows, the part of the grenade, the bottom with a smoke charge, remains either at the place of its operation, or in the expansion area of its other parts with a burning open end of its smoke charge (see surface 14 in figure 2). From that moment on, the grenade operates in smoking grenade mode.

At the end of the burning of a part of the smoke charge to the perforated gaskets, its combustion products through the openings in the gaskets ignite the part of the smoke charge located in the bottom of the casing, and this process continues until the charge is completely burned out.

From the description of the patentable cartridge shows that its grenade due to the use of a plastic case and other technical solutions has a significantly greater smoke charge and is able to function without a bursting charge in two successive modes: explosive and smoking. Therefore, it eliminated the disadvantages of the analogue and prototype and it alone can perform the tasks of target designation, setting a tactical smoke screen with a lower consumption of cartridges and the fight against the enemy, placed in the premises. In addition, the patented cartridge has other advantages over the well-known:

- its parts of the smoke charge can differ in burning speed due to the pressure of their pressing, and due to the use of different smoke compositions;

- in it, by moving the fuse to the head bottom of the grenade, it is possible to significantly change the masses of the parts of the smoke charge that are fired in explosive and smoking modes.
