Description

The invention relates to ammunition, and in particular to smoke protection devices of a modular type, for example in the form of a cartridge with a smoke bomb for remote installation.

Known smoke protection devices of a modular type, consisting of smoke bombs that are laid out on the ground and when set on fire create a protective smoke cloud (see Smoke bombs ШД-ММ, ШД-П. Sat .: Explosives, pyrotechnics, means of initiation in the post-war period. Publishing house "Humanism", M.-SPb., 2001, p. 499).

Also known is a smoke bomb for remote installation (prototype), used from helicopters and ground systems and consisting of a body with a diaphragm and a smoke composition with an igniter (see Smoke bomb UDSH. Sat: Explosives, pyrotechnics, means of initiation in the post-war period. Publishing house "Humanism", M.-SPb., 2001, p. 500).

In the above-mentioned known smoke protection devices, the initiation of the smoke-forming composition occurs at the time of their ejection from the carrier, so the smoke curtain created by them is created during the passage or passage of the vehicle from which they are installed. However, the known smoke protection devices do not provide the possibility of early remote installation of the pieces on the ground in a given place and their initiation at the required time.

The invention is aimed at eliminating the above disadvantage of both analogues and prototype.

The technical result obtained from the implementation of the claimed invention is to provide, where necessary, the possibility of advance remote installation on the ground in a given place of the smoke protection device with its subsequent activation at the required time.

The inventive device of smoke protection of a modular type contains a guide cup, a piston with a knockout charge and a smoke bomb in the housing, inside which a smoke-forming mixture, a diaphragm with holes and a knockout igniter are placed. Unlike the prototype, the smoke bomb body is made in the form of a cylindrical glass and a lid with an internal cavity and a socket at its lower end, as well as ring grooves on its side surface. The bottom end of the lid is recessed inside the cylindrical glass and tightly pressed by its side surface to its inner wall, and the lid itself is fixedly mounted on the cylindrical glass during transportation for destructible connection in the form of crimping the edges of the cylindrical glass in an annular groove on the side surface of the cover. At the same time, the lid with its lower end adjoins the diaphragm, forming together with it a closed cavity, inside which a knock-out igniter charge is placed, while the cylindrical glass with the lid rests with its bottom on the piston and is held in transport position motionless relative to the guide glass with a destructible connection in the form rolling the edges of the guide cup, resting rolling against the upper end of the lid. Moreover, the smoke bomb is equipped with a radio receiver with an electric fuse connected to its output, which are located respectively in the inner cavity of the lid and in the knockout igniter, and the antenna of the radio receiver is placed during transportation in one of the ring grooves on the side surface of the lid.

The attached drawing shows the inventive smoke protection device of a modular type.

The modular type smoke protection device contains a guide cup 1, in which a piston 2 with a knockout charge 3 is placed. In addition, a smoke bomb (21) containing a cylindrical cup (4) with a cover (10) is placed inside the guide cup (1). A smoke-forming composition (11) and an adjacent diaphragm (5) with openings for the exit of smoke are placed inside the cylindrical glass (4). The inlet of the cylindrical cup (4) is closed by a lid (10) having an internal cavity (12) and a socket (13) at the lower end (18), and annular grooves (14) on the side surface. The bottom end (18) of the cover (10) is recessed inside the cylindrical glass (4) and fits snugly with its side surface (15) to its inner wall (16) and at the same time lies with its bottom end (18) to the diaphragm (5) with holes for smoke exit, forming together with it a closed cavity (19). A kick igniter (6) is placed inside the closed cavity (19), and an electric fuse (8) is located inside the latter. The smoke bomb (21) rests against the bottom of the cylindrical bowl (4) against the piston (2) and is held motionless relative to the guide bowl (1) during transportation by rolling (20) the edges of the guide bowl (1) and the stop by this rolling (20) into the cover ( 10). During transportation, the cover (10) is also fixed motionless relative to the cylindrical glass (4) with a destructible connection in the form of a crimp (17) of the edge of the cylindrical glass (4) in an annular groove on the side surface (15) of the cover (10). In the inner cavity (12) of the lid (10), a radio receiving device (7) is placed, to the output of which is connected a wire line of an electric fuse (8). The antenna (9) of the radio receiver (7) for the duration of transportation is laid in an annular groove (14) on the side surface (15) of the cover (10).

After the modular type smoke protection device falls onto the ground, a kick charge (3) is triggered. The pressure of the powder gases, the detonating charge (3), flares the edges of the guide cup (1), and then the smoke bomb (21) is pushed out of the guide cup (1) beyond. After the smoke bomb (21) leaves the guide cup (1), the antenna (9) of the radio receiver (7) is straightened, and the smoke bomb (21) itself is installed on the ground. From this moment, the radio receiving device (7) is ready to receive control signals. With the arrival of the signal to activate the smoke bomb (21) from the output of the radio receiver (7) at the specified time to the input of the radio receiver (7), a current pulse is fed through the circuit to the electric valve (8). Having worked, the electric fuse (8) initiates a knock-out igniter charge (6). The pressure of the powder gases of the triggered expelling igniter charge (6) destroys the crimp (17) of the edge of the cylindrical cup (4) and pushes the cover (10) with the radio receiver (7) and its antenna (9) completely, freeing the outlet of the cylindrical cup (4) . At the same time, the powder gases of the triggered expelling igniter charge (6) are ignited through the holes in the diaphragm (5), the smoke-forming composition (11). The smoke formed during the combustion of the smoke-forming composition (11) will escape through the openings in the diaphragm (5) and the free outlet in the cylindrical glass (4) into the free space, forming a large protective smoke cloud in it. The process of formation of a protective smoke cloud will occur continuously until the smoke-forming composition is completely burned out (11). The increased pressure of the powder gases generated during the combustion of the expelling igniter charge (6) in a closed cavity (19) provides, on the one hand, destruction of the crimp (17) of the edge of the cylindrical glass (4), and, on the other hand, reliable ignition of the smoke-forming mixture by powder gases ( 11) through the holes in the diaphragm (5).

From the foregoing, it follows that the new technical solution proposed by the applicant for a modular type smoke protection device, if implemented, can provide, if necessary, the possibility of installing it on the ground in advance at a specified location, and then activating it at the required time.
