Description

The invention relates to non-lethal weapons, designed for remotely throwing an immobilized network when detaining violators of a protected territory or violators of public order.

A weapon is known for ejecting a stopping network when detaining public order violators, which is a pipe inside which there is a nylon or rope network and a strong spring (see French patent No. 2509848 of 03.23.1981, M. CL F41H 13/00). The known device also has a trigger guard, like a pistol. When you press the trigger, the pre-charged spring opens and throws the net. The network covers a person at a distance of up to 3 m, leading him to a state of immobility.

Also known is a device (prototype) for combating public order violators, which is mounted permanently on the roof of the car and includes a starting device (housing), from which the network is fired using two missiles or other flying shells fixed in corners along the front edge of the network (see patent Germany No. 2166225 dated 10/05/1971, N. class. 57a, 40). Two flying projectiles, which can be used as rockets capable of moving the network through the air at a distance of 25 m to 30 m. The network is lowered to the ground after burning of the powder charge of the rocket, and a load in the form of a tow rope is fixed to the front edge of the network to ensure so that in flight the network does not collapse, and when the network lands, it is dived. The launching device includes a horizontal mesh platform and two guides for missiles, pivotally mounted on the side posts that swing over the sides of the car, while the distance between the guides is 3.2 m, which allows the use of a network 3 m wide. When fired, the network covers from above a group of violators of public order. After the shot, the device is recharged by the operator. In the description of the above prototype, the use of a design variant of the known device against hijackers of aircraft when the aircraft is in flight is proposed. The same known device is proposed to be used as a means of self-defense against an attacker in order to physically incapacitate him for a sufficiently long time.

An analysis of the above known devices for remotely throwing an immobilizing network on public order violators during their detention shows that these devices have the following disadvantages.

Using the energy of a compressed spring in a firing device cannot be effective, because its range when shooting at point-blank range does not exceed 3 m, which in most cases arising from the detention of an intruder is insufficient.

When using a launcher based on the throwing of a network with the help of a powder charge of rockets, there is a high probability of a lethal defeat of violators. At the same time, throwing the network with the help of a powder charge of rockets, so that the network covers violators at a distance of 25-30 m from above after burning powder charges, is inefficient, because during the flight of the network and its landing, violators can simply run away or avoid entanglement by the network, using the means at hand - tree branches, banners, etc.

If the launcher is mounted on a vehicle, mobility in using the known immobilizer will be significantly lower compared to the manual version of the launcher.

The purpose (technical result) of the claimed invention is to eliminate the above-mentioned disadvantages of analogues and prototype, to ensure the detention of the intruder in a wide range of ranges, the compactness of the device, the possibility of its use as part of a standard small arms, aiming action.

To achieve the above technical result, a new missile network for non-lethal immobilization of biological objects and a device for its remote throwing are proposed. In contrast to the well-known, a new network for non-lethal immobilization of biological objects, containing a network fabric woven from strong elastic threads and weights fixed on it, is formed into a cylindrical block. The folded network web is located inside the unit, and the loads are evenly spaced around the outside. The loads have an elongated shape, grooves are made at the ends of the loads. On the outer surface of the cylindrical block on each load there is one or more protrusions located evenly along the length of the load. One end of the block is installed in a case made in the form of a glass, while the block is held in the glass by a destructible connection, for example, by the spring paws of the glass, inserted into the grooves of the cargo. The pyrotechnic moderator and the expelling powder charge are sequentially placed in the bottom of the glass. A piston is located between the powder charge and the cylindrical block with the net and weights. On the opposite side of the cylindrical block, the goods are connected by a ring, introduced into the grooves of goods.

Pyrotechnic moderator can be multistage and consists of a fixed and rotary parts. In the fixed part, channels are arranged parallel to each other in a circle with retarders installed in them having different response times. In the rotary part, a radially displaced channel with a moderator is made, the axis of which is parallel to the axes of the channels of the fixed part, and its radial displacement ensures coincidence with the channel axes of the fixed part during rotation of the rotary part.

The loads are connected to the network web by thread ties, the attachment points of which to the web are evenly distributed along its perimeter, and their length ensures the arrangement of goods around the circumference when the network opens.

A device for remote network sprinkling contains a barrel and a propelling charge. The barrel is made with internal spiral grooves, for example, similar to an under-barrel grenade launcher, and it houses a network with loads in the block, while the protrusions of the loads are engaged with the spiral grooves of the body, and the propellant charge is located between the bottom of the barrel and the pyrotechnic moderator of the network.

The new design of the network and devices for its remote throwing proposed by the applicant and the authors is most compact, provides the possibility of aimed throwing of the network, including shooting at close range, because the total weight of the weights is evenly distributed around the circumference, which allows you to choose the mass of a single weight, safe when it enters a person. When using the proposed device, the detention of the intruder is possible in a wide range of ranges, because the range is determined by the throwing speed of the cylindrical block with the network and the time of slowing down its opening on the trajectory, which can be adjusted.

The figure 1 shows on a reduced scale the network with the goods in the expanded state.

The network consists of a network web 1 and loads 2 connected to the web by thread ties 3. In the assembled state, the network with the loads laid outside it uniformly around the circumference forms a cylindrical block 4. The loads 2 have an elongated shape, grooves 5 are made at their ends, and along the length evenly placed one or more protrusions 6, which are located on the outer cylindrical surface of the block 4. One end of the block 4 is installed in the glass 8 and fixed in it by spring tabs 7, which are meshed with grooves 5 of the goods 2. On the opposite side RCE unit loads 2 are connected to the ring 9 mounted in the grooves 5 of cargo. In the bottom part of the cup 8, a sleeve 11 is installed with a knockout charge 12 and a moderator 13. A sealant (wad, piston) is placed between the knockout charge 12 and the net with loads 2 14. The dimensions and shape of the cylindrical surface of the block 4 formed by the loads 2 are provided externally by spring paws 7 and the ring 9, and on the inside, by focusing the weights on the protrusion 15 of the seal 14 and the plug 16.

The device for remote network sprinkling is a barrel 10, in which a block 4 with a network, a knockout charge 12 and a moderator 13 is placed. A throwing charge 18 is located between the moderator 13 and the bottom 17 of the barrel 10. Spiral grooves 19 are made in the barrel 10, while the protrusions 6 goods are meshed with grooves.

Multistage moderator consists of two parts. In the fixed part is placed bouncing charge 12 and channels 20, evenly spaced around the circumference. In the channels 20, moderators 21 are installed with different response times. In the rotary part 22, a channel with a moderator 23 is made. The distance from the axis to the channel of the moderator 23 is equal to the radius of the channels 20.

The network and device are as follows.

The propellant charge 18 is activated by one of the known methods, for example, with a firing mechanism. When using an under-barrel grenade launcher, a propellant charge is triggered by its trigger-trigger device with a pruning mechanism. The powder gases of the propellant charge 18 push the cylindrical block 4 out of the barrel 10 and at the same time set the moderator 13 or 23 on fire. When the block 4 is axially moved in the barrel 10, it acquires a rotational movement due to its protrusions 6 engaged with the spiral grooves of the barrel. The resulting rotation stabilizes the movement of the block on the trajectory after it leaves the trunk.

After burning of the moderator 13 or sequential burning of the moderators 23 and 21 during the movement of the block on the trajectory, a blow-out charge 12 is triggered, the powder gases of which through the seal (piston) 14 push the cylindrical block with the network 1 with loads 2 from the glass 8. The centrifugal force of the loads, perceived by the walls glass 8 and the ring 9, after the release of goods from the glass 8, unfolds the loads relative to the ring 9 and after they disengage from the ring 9 gives the loads in addition to the axial radial speed, while the loads, expansion When moving in different directions, they straighten the network and in the expanded state it moves to the object of detention. Having reached the object, loads with thread ties cover the target and the network entangles it.

When the network is deployed, the aerodynamic resistance to its movement increases and the speed is quickly extinguished, therefore, to delay an object located at a distance of more than 15 ... 20 m, it is necessary to delay the network opening.

To ensure the possibility of delay in a wide range of distances, a multistage moderator is used. When the rotary part 22 is installed in one of the fixed positions, the axis of the moderator 23 coincides with the axis of one of the channels 20. In this case, one of the moderators 21 operates in series with the moderator 23, increasing the time of the oriented flight of the cylindrical block with the network and, accordingly, its opening range. Taking into account the aiming of firing (for example, from a grenade launcher), the deceleration time is set, adjusted to the required distance to the object.

In view of the above arguments, it follows that the claimed device for remotely throwing an immobilizing network provides high efficiency, an increase in the range of its action, the possibility of its individual use by an individual fighter of special forces, and the non-lethality of its use.
