Description

Field of technology

The proposed invention relates to the field of production of firearms, in particular to ammunition for hitting fast-moving targets, in particular unmanned aerial vehicles (UAVs).

The proposed technical solution is versatile and can be integrated into existing designs of rifled firearms of virtually any caliber, including the widely used 5.45 mm and 7.62 mm calibers.

State of the art

The prior art includes devices and charges for combating UAVs using an underbarrel grenade launcher—"Device for Firing Hunting Cartridges from an Underbarrel Grenade Launcher" (patent RU227995) and "Energy-Containing Microgrenade Designed to Destroy a Swarm of Low-Speed, Slow-Speed, and Low-Speed Unmanned Aerial Vehicles" (patent CN117367222A). However, aiming with an underbarrel grenade launcher is challenging.

Ammunition filled with various striking elements is known—"Bullet with striking elements" (patent RU2839205) and "Cartridge for combating UAVs" (patent RU228896). The use of such ammunition accelerates the destruction of the firearm's barrel due to damage caused by contact between the inner walls of the barrel and the ejected striking elements.

The "Impulse sprayer for standard combat and deactivated weapons with a caliber attachment on the weapon's barrel for loading and spraying fire extinguishing agents and natural substances—water, sand, soil, dust—during wildfire suppression" (patent RU 2776283) uses a special container screwed onto the barrel and filled with a spray charge. The sprayer is used only for firing deactivated weapons or combat weapons, but with blank cartridges.

The "Dronoboy" (Droneboy) shotgun attachment for destroying unmanned aerial vehicles (UAVs) was selected as the prototype (https://www.dmazay.ru/index.php?productID=15448). The device consists of a special screw-on attachment for the Kalashnikov AK-74, AK-103, and AK-105 assault rifles and special shot containers loaded with powder and solid lead pellets. The shot from the container is initiated by firing a special flashbang cartridge from the assault rifle. However, the availability of this special cartridge and the ability to retrofit it to the assault rifle in real combat are not always feasible.

Disclosure of invention

The objective of this invention is to increase the effectiveness of destroying unmanned aerial vehicles (UAVs) with rifled weapons by using a threaded nozzle and a container with striking elements.

The stated problem is solved and the technical result is achieved by a device for firing steel shot, consisting of a threaded muzzle attachment and a container with steel shot loaded with a powder charge, characterized in that the container additionally contains ties, a plastic lid, a steel core, a rubber wad, wherein the steel core is an article made of a steel tube with an internal diameter 1 mm larger than the diameter of the barrel of a rifled weapon, with a base in the form of a flat and round washer welded to one of the bases of the tube with a central hole diameter equal to the internal hole of the steel tube and an external diameter equal to the internal diameter of the container; the container is made of a plastic material; the shot is made of steel. When assembling the container, a plastic container is placed on the steel core until it stops, the container is secured with a rubber wad on the combustion chamber side, ties are inserted between the sole of the core and the wad to further secure the powder charge, balls are placed in the cavity between the walls of the container and the steel core, and the container on the opposite side from the combustion chamber is closed with a plastic lid, which is fixed on the groove of the core.

Implementation of a utility model

The device for shooting steel shot, hereinafter referred to as the "product", consists of the following main elements:

1. Plastic container.

2. Ties.

3. Plastic lid.

4. Steel ball.

5. Steel core.

6. Rubber wad.

7. Adding gunpowder.

8. Threaded muzzle attachment.

9. Rectangular protrusions.

10. Inner hole of the core.

The striking elements are all parts of the product that are part of the container (1) (Fig. 1).

The plastic container (1) of circular cross-section has a wavy edge on the side where the powder (7) is loaded, allowing one to tactilely determine which edge to load the finished container (1) into the nozzle (8). The inner surface of the container cavity (1), where the balls (4) are placed, has rectangular projections (9) (Fig. 3). The projections (9) absorb the impact of the compacted charge of balls (4) during launch. The walls of the container (1), on which the projections (9) are located, collapse, and the balls, flying out of the nozzle, fly freely, creating the necessary cloud for destruction.

The steel core (5) is a product made of a steel tube with an internal diameter 1 mm larger than the diameter of the barrel of a rifled weapon, with a flat and round washer welded to one of the bases of the tube, which serves as the base of the core (5), with the same central hole and the external diameter of the washer equal to the internal diameter of the container (Fig. 4). The core (5) serves as a central base for the assembly and fixation of all components of the cartridge case around it and on it. The internal hole (10) serves to freely pass the bullet of the rifled weapon. The strength of the steel wall allows for protection of the components of the container (1) from destruction by the pressure of the powder gases of the bullet of the rifled weapon and the powder charge (7) of the container (1) itself.

The plastic cap (3) with the inscription "ON TARGET" is made of plastic and has a bright color, indicating the direction of the charge's flight (Fig. 5). It is fixed with its own hooks on the grooves of the steel core (5), holding the balls (4) in the container (1).

The ties (2) are designed to secure the polyethylene bag with the powder charge (Fig. 2).

The container assembly is performed as follows. The plastic container (1) is placed onto the steel core (5) until it stops. It is secured with a rubber wad (6) on the combustion chamber side. Straps (2) are inserted between the base of the core (5) and the wad (6) to further secure the propellant charge (7). Balls (4) are placed in the cavity between the walls of the container (1) and the steel core (5) and closed with a plastic lid (3), which is secured to the groove of the core (5).

To throw the product, a rifled firearm with an external thread on the end of the barrel is required. A smoothbore threaded muzzle attachment (8), made of precision cold-drawn tube with an internal diameter of, say, 30 mm, is screwed onto this thread. The breech is thicker than the extension of the smoothbore section (Fig. 6). This extension of the rifled weapon allows for aimed throwing and does not interfere with small-arms combat, using the full arsenal of sighting devices, including for night shooting. In addition, at night, the muzzle attachment (8) acts as a flash suppressor - afterburning of powder particles formed after the shot. The product is loaded using a mortar principle. The container (1) is sent into the breech of the attachment (8) using improvised means or a specially designed feeder, allowing for a shorter time between throws and compliance with all safety requirements for the use of firearms.

In order to implement the possibility of throwing a container (1) using existing types of rifled weapons from various shooting positions, i.e. lying down, sitting, kneeling, standing, without causing injury to the shooter from recoil, standards for the powder charge, diameter and weight of the container (1) were calculated and adopted.

The principle of launching the product is similar to that of firing shot from a smoothbore gun. The product is generally similar to a shot container for a smoothbore gun. The fundamental difference is the presence of a central hole (10) in the container (1), through which the bullet of a rifled weapon flies. On its path, the bullet first passes through the powder charge (8), pierces the wad (6), then flies through the steel tube of the core (5) and destroys the lid (3) of the container. The wad (6), pierced by the bullet, closes behind it, while maintaining sufficient tightness in the combustion chamber. In the combustion chamber, the powder gases from the rifled weapon ignite the powder charge (7) of the product. A zone of high pressure is created behind the container (1). The container (1) and all its contents are accelerated down the barrel. The steel balls (4) are compacted, creating pressure not only on the base but also on the walls of the container (1). The container walls initially begin to adhere more tightly to the surface of the nozzle (8), increasing the obturation, then they collapse and fly out along with all the elements of the container (1). Upon exiting the smooth bore of the nozzle (8), the balls (4), having a large kinetic mass, rush to the aiming point behind the bullet. The bullet flies first, then the steel core (5), followed by the balls (4) and the remains of the container (1). All this forms a "clod and tail" cloud. With varying speed and force, in vertical section the striking elements form a dense elliptical cloud at a distance of 50 meters, having a height of 3 meters and a width of 2.5 meters. The bullet of a rifled weapon does not change its flight trajectory.

Since fragments of the destroyed container and powder residue may remain in the table after throwing, a single shot or burst is necessary. This procedure completely cleans the inside of the cartridge case before reloading it for throwing.

The steel shot firing device is designed to disable low-flying targets, including UAVs, at altitudes of up to 80 meters.

Repeated use of the device has demonstrated its high effectiveness and received significant positive feedback from military personnel. The data demonstrates a high level of satisfaction with the device's functional characteristics and confirms its feasibility for use in combat situations. Furthermore, a consistent trend was identified in favor of the device's rapid introduction into mass production, indicating its demand and potential for widespread use in military operations.
