Description

The utility model relates to the field of military equipment, namely to the field of developing weapons and ammunition, and can be used to destroy manpower, as well as to the field of means for conducting combat operations, and in particular to means for placing ammunition on vehicles, combat vehicles, their transportation to the place of both training and military operations.

Known systems of smoke grenade launchers designed to protect armored vehicles from weapons, consisting of a control panel, mortar for smoke grenades and actually smoke grenades. The control panel is designed for sequential transmission of an electrical impulse to the expelling charge of a smoke grenade and consists of a housing and switches. The mortar is a short metal pipe with electrical contacts in a hermetically sealed end part. Smoke grenade is an ammunition with an expelling charge located in the end part, and an aerosol-forming composition. This system is used to set aerosol curtains in order to counter the means of destruction of armored vehicles and fixedly mounted at a certain angle (usually 45 °) on the armored object (Fomich N. Tanks of the armies of the capitalist countries // Foreign Military Review. - 1988. - No. 1. - C .29-38. Viktorov E. Armored vehicles of Austria // Foreign Military Review. - 1988. - No. 12. - P.33-36. Safonov B. Increased Tank Survivability // Foreign Military Review. - 1989. - No. 1. - S.25-30. Fomich N. American tank M1 "Abram" and its modifications // Foreign military about review. - 1990. - No. 2, 10. - P.34-40).

The disadvantages of this system are:

- the inability to use it for setting aerosol curtains regardless of the rotation of the turret of the armored object and the object as a whole;

- the inability to change the angle of inclination of the mortars due to the rigid attachment to the inclined sheet of the armored object;

- the impossibility of setting blinding aerosol curtains using incendiary smoke cartridges.

A device for installing smoke grenades (Patent 2122705 RU, IPC F42B 5/155. Device for installing smoke grenades / BN Borovkin, VA Voronkin, VN Trifonov RU. - No. 97102920/02; 02/25/1997; Publ. 27.11.98), which contains removable brackets with sockets for placing smoke grenade trunks in them and is rigidly bolted to one of the front inclined sheets of the tower on the sealant with bolts at the locations of the figured windows for placing electrical circuit elements in them.

The disadvantages of this device are:

- the impossibility of firing mortars with ammunition with jet engines;

- the impossibility of setting blinding aerosol curtains using incendiary smoke cartridges.

The closest to the principle of operation and technical solution is the patent (Patent No. 2156947 PU, IPC F42B 5/155, F41A 23/34, F41H 9/06. Smoke grenade launcher / Klyuzhin A.V., Kirichenko V.I., Manko V. .L. et al. - No. 99104984/02; Declared March 15, 1999; Published on September 27, 2000 - Bull. No. 35. - 2002). Its essence lies in the fact that the installation contains a control panel, a base placed on the body of the armored object, and made in the form of a rotating platform rotating in the horizontal plane, equipped with a rotation device and two racks installed perpendicular to the base. In this case, the mortars are made in the form of cassettes with pins located in holes made at the free ends of the racks. The rotation device has a drive in the form of an electric motor, and the cassettes are equipped with a vertical rotation mechanism.

However, this smoke grenade launcher is characterized by the following disadvantages:

- the installation can put only the aerosol curtain at a distance corresponding to the specific (fixed) position of the fixed barrel of the mortar;

- the installation can only put an aerosol curtain in the direction determined by turning the turret of the armored object, or by turning the armored object as a whole;

- the installation cannot deliver blinding aerosol curtains using incendiary smoke cartridges.

The technical task of the proposed utility model is to increase the efficiency of the production of smoke and blinding aerosol curtains in order to mask and protect the object from precision weapons and other weapons.

The technical result that can be obtained using the utility model is to expand the functionality of the installation, namely, in the complex (instant and smoking principle of the incendiary smoke cartridge and smoke grenade, respectively) staging of masking and blinding aerosol curtains at various distances and at various directions regardless of the position of the tower and the armored object itself.

This object is achieved in that the smoke grenade launcher with a device for attaching and launching incendiary smoke cartridges contains a control panel, a base located on the body of the armored object, a rotary device equipped with a drive in the form of an electric motor, a mortar made in the form of cartridges with opening caps and equipped with a rotation mechanism in a vertical plane with an electric motor drive and containing removable swivel brackets with a socket for accommodating incendiary smoke chambers and latches in to change their position in the vertical and horizontal planes, wherein the electrical circuit to smoke grenades and smoke incendiary cartridges are connected to the control unit.

The claimed technical solution is illustrated by drawings 1-3.

Figure 1 shows a device for installing incendiary smoke cartridges on a mortar with a smoke grenade, including:

1 - a mortar with a smoke grenade;

2 - incendiary smoke cartridge;

3 - clamps;

4 - removable swivel brackets.

Figure 2 shows various options for the placement of incendiary smoke cartridges relative to mortars with smoke grenades (front view, where the device is rotated 90 °).

Figure 3 explains the principle of use of a smoke grenade launcher with incendiary smoke cartridges.

In the initial state, two removable swivel arms 4 are installed on the barrel of the mortar 1 (Fig. 1) to launch smoke grenades. the lower one - with a socket for placing the incendiary smoke cartridge 2 and changing its position in the horizontal plane, and the upper one - for changing the position of the incendiary smoke cartridge in the vertical and horizontal planes. This allows you to rotate the incendiary smoke cartridge 2 around the mortar with a smoke grenade 7. After installing the rotary brackets 4 in predetermined positions, they are fixed with clips 3. Installing an incendiary smoke cartridge on the smoke grenade launcher installation of an armored object is installed to each mortar with a smoke grenade (figure 2). Thus, the installation of an incendiary smoke cartridge has a separate support for each mortar with a smoke grenade for fastening in its end part with fastening clamps. The system for starting an incendiary smoke cartridge is carried out using a standard control panel of a smoke grenade launcher with the additional use of a group of contacts of electrical wiring and toggle switches in a standard panel to supply electric current to the contacts of incendiary smoke cartridges.

Before combat use, incendiary smoke cartridges are installed on all mortars of a smoke grenade launcher installation of an armored object, which are set in a given direction in both horizontal and vertical planes. In the process of moving an armored object, these positions can be adjusted regardless of the direction of movement of the armored object or the angle of rotation of the turret. The electrical circuit of the armored object is always prepared to supply voltage to the smoke grenade launcher.

Installation works as follows. The command to launch both a smoke grenade launcher and an incendiary smoke cartridge comes from the control panel. In this case, electric current from the on-board network of the armored object through the control panel and the contacts of the smoke grenade launch system is supplied to the electric igniter. The latter is triggered, which leads to a sharp increase in pressure and temperature as a result of ignition of the powder explosive charge of a smoke grenade. Under the action of a force formed by the pressure of gases on the end part of the smoke grenade, it begins to move along the inner channel of the mortar. After the smoke munition exits the mortar channel by setting the elevation angle and the horizontal direction, the flight range of the munition and, accordingly, the aerosol curtain setting line are adjusted.

The principle of operation of an incendiary smoke cartridge and a mortar with a smoke grenade are the same. However, the range and direction of flight of the incendiary smoke cartridge can be changed not only by the device to give the incendiary smoke cartridge the required elevation angle, but also by turning the brackets around the mortar with a smoke grenade at an angle of ± 180 °.

Figure 3 shows the various uses of incendiary smoke cartridge and mortar with smoke grenade:

1 - flight path of incendiary smoke cartridge with a maximum elevation angle (position "a" in figure 2);

2 - standard flight path of a smoke grenade;

3 - the flight path of the incendiary smoke cartridge with a minimum elevation angle (position "in" in figure 2);

4 - flight path of a smoke grenade with remote detonation in the air;

5 - direction of flight of a smoke grenade;

6 - the direction of flight of the incendiary smoke cartridge from position "b" (figure 2);

7 - aerosol curtain.

The claimed technical solution allows the installation of additionally blinding aerosol curtains at various distances and directions, regardless of the position of the fixed mortar, the direction of the tower and the armored object itself.

In addition, the combination of the electric circuits of the smoke grenade launch control panel and incendiary smoke cartridges through the common control system of the smoke grenade launcher allows one shot of a smoke grenade from the mortar and one or more simultaneous launches of incendiary smoke cartridges.

The complex use of a smoke grenade launcher with incendiary smoke cartridges increases the lifetime and range of a masking aerosol curtain as compared to the existing Cloud and Shtora systems when the enemy uses high-precision weapons and anti-tank weapons.

Thus, the proposed technical solution allows to increase the efficiency of existing means of aerosol masking of armored objects without significant changes in their design and to expand the functionality of a standard smoke grenade launcher due to the integrated use of smoke grenades and incendiary smoke cartridges.
