Description

[0001] The invention relates to methods and devices for combating unmanned (remotely piloted) aerial vehicles (UAVs).

[0002] Currently, various types of UAVs are actively used in the preparation or conduct of military operations.

[0003] The main tasks of the UAV are as follows:

[0004] conducting aerial reconnaissance;

[0005] opening objects (targets);

[0006] identification of routes (paths) of movement;

[0007] terrain reconnaissance;

[0008] Issuing target designation and adjusting artillery fire.

[0009] To directly cover units from UAV reconnaissance and prevent them from using munitions, platoon-company-battalion units typically employ traditional counter-aircraft weapons, such as concentrated and barrage fire from small arms. However, the use of small arms against UAVs can be ineffective. The main problem with countering UAVs with small arms is their small size. Their small size prevents them from being effectively targeted by anti-aircraft artillery systems and small arms.

[0010] A device for countering UAVs using a decoy net is known (RU 72753 U1, 27.04.2008; RU 72754 U1, 27.04.2008). After detecting a UAV, the net is delivered to the desired point in space in a container and launched toward the aircraft. To improve the effectiveness of the UAV engagement, metallized threads in the net cells and weights with containers with adjustable parachute properties in flight are used. The size of the net determines the amount of compensation for guidance errors. A disadvantage of this approach is the need for precise and timely delivery of the container with the net to a strictly defined point in space, as well as its dependence on weather conditions (e.g., wind direction and speed).

[0011] A known airborne counter-UAV weapon (RU 94690 U1, May 27, 2010) is a mini-UAV equipped with a directional or non-directional munition and a control system for its detonation. Its main drawback is the need to ensure the mini-UAV remains airborne at all times, regardless of the presence of enemy unmanned aerial vehicles. Furthermore, targeting an enemy UAV with a guided missile will be challenging, including its small radar cross-section and weak IR radiation from its engines. Using a non-directional munition will damage (or destroy) the UAV, precluding its reuse.

[0012] There are many known methods of electronic countermeasures and devices for their implementation, which provide suppression (distortion) of radio navigation, control channels, and UAV data transmission (disruption of the functioning of onboard electronic equipment).

[0013] At the same time, these methods are highly technological, which implies increased cost and high requirements for the operator’s qualifications.

[0014] Thus, the general disadvantage of known methods and devices for combating UAVs is the impossibility of their use by military personnel as an individual means of combating enemy UAVs both during preparation and during combat due to their high cost, design complexity and difficulty in use without special training.

[0015] These circumstances allow us to conclude that at present there are practically no easy-to-use individual means that would allow each serviceman to effectively combat enemy UAVs both during preparation and during combat without lengthy preliminary training.

[0016] At the same time, the Russian Army is armed with the 40mm GP-25 (GP-30, 34) underbarrel grenade launcher, a personal weapon designed to destroy exposed manpower, as well as manpower located in open trenches, ditches, and on reverse slopes. The 40mm underbarrel grenade launchers, which are mounted under the barrel of the Kalashnikov AKM and AK-74 assault rifles, are widely used with grenade launcher rounds: primary grenade launchers with fragmentation, high-explosive, and incendiary grenades, and special-purpose grenade launchers with illumination, smoke, and gas grenades. However, the above-mentioned ammunition types are not intended for firing at aerial targets, particularly UAVs.

[0017] The 6G30 hand-held anti-personnel grenade launcher [40 mm Hand-held anti-personnel grenade launcher 6G30 Operating Manual 6G30 RE] is known, consisting of a buttstock with a butt pad, a barrel block, a grip with a cover, a sighting frame, and a grip with a trigger mechanism. However, grenade launcher rounds for the 6G30 are not intended for firing at aerial targets, in particular at UAVs, and the design of the hand-held anti-personnel grenade launcher does not allow the use of 12-gauge shotgun cartridges, effective against drones, or anti-drone cartridges produced by domestic and foreign industries, such as the "Intercept" or "Sky Net Mi-5."

[0018] Thus, the disadvantage of the analogue is the impossibility of firing a 12-gauge cartridge at air targets, in particular at UAVs.

[0019] A device for firing hunting cartridges from an underbarrel grenade launcher is known, selected as a prototype (RU 227995 U1, 12.08.2024), comprising a hollow cylindrical body consisting of a main and a breech section, and also configured to be installed with an interference fit in the barrel of an underbarrel grenade launcher, wherein the outer diameter of the breech section is smaller than the outer diameter of the main section, on the side adjacent to the breech section, an annular groove and a chamfer are made, configured to ensure reliable fixation of the device in the underbarrel grenade launcher. The section of the main section on the muzzle side is made with a smaller outer diameter compared to the section of the main section on the side adjacent to the breech section, on which an annular groove and a chamfer are made. The two sections of the main section are made disassemblable and are connected to each other using a threaded connection.

[0020] A drawback of the prototype is its low effectiveness, due to the need to reload the underbarrel grenade launcher and insert barrel after each shot. This significantly reduces the effectiveness of this technical solution due to the low probability of hitting a moving target with the first shot.

[0021] The objective and technical result that the claimed invention is aimed at achieving is to eliminate this drawback.

[0022] The technical result is achieved by using an insert barrel containing a hollow cylindrical body consisting of a main and a breech part; on the main part, on the side adjacent to the breech part, an annular groove and a chamfer are made; the hollow body on the side opposite from the breech part contains a skirt, as well as an anti-wear insert.

[0023] The method of firing a 12-gauge cartridge from the 6G30 hand-held anti-personnel grenade launcher is carried out using an insert barrel, in which the breech of each insert barrel is loaded with a 12-gauge cartridge and inserted one by one into all six barrels of the barrel grenade launcher block until the lock clicks into the annular groove of each insert barrel, an anti-wear insert is installed in the tube and firing is carried out at air targets, with firing being carried out from a supine, kneeling or standing position.

[0024] The proposal is explained with pictures, where:

[0025] Fig. 1 shows the device of the insert barrel;

[0026] Fig. 2 shows the device of the anti-wear liner;

[0027] Fig. 3 shows the 6G30 anti-personnel grenade launcher;

[0028] Fig. 4 shows the placement of the anti-wear liner in the tube of the anti-personnel grenade launcher;

[0029] Fig. 5 shows a photo of the insert barrel test.

[0030] The declared insert barrel 1 for firing a 12-gauge cartridge from the 6G30 hand-held anti-personnel grenade launcher comprises a hollow cylindrical body 2 consisting of a main and a breech section. An annular groove 3 and a chamfer 4 are made on the main section on the side adjacent to the breech section, and a skirt 5 is made on the opposite side (see Fig. 1). Skirt 5 prevents pellets from sticking after firing into the gap between the outer edge of the barrel block 6 and the tube 7 and ensures the exit of the pellet charge directly into the tube 7. This gap does not negatively affect the firing of a standard rocket-propelled shot; however, based on practical firing of a 12-gauge cartridge, this gap should be reduced.

[0031] An anti-wear insert 8 is installed in the channel of the pipe 7 until its flange 9 touches the cover 10. Insert 8 prevents damage to the inner surface of the channel of the pipe 7 by shot or segments of anti-drone cartridges.

[0032] The claimed device operates as follows.

[0033] Before firing, the shooter loads the insert barrels 1 with a 12-gauge cartridge or anti-drone cartridges. To do this, a hunting or other cartridge is installed in the breech of the hollow body 2. Next, all six barrels of the block 6 of the grenade launcher are inserted one by one until the lock clicks into the annular groove 3 of each insert barrel, which ensures its secure fixation. Anti-wear insert 8 is installed inside tube 7 from the side of block 6 in advance of or immediately before firing until flange 9 touches the inner side of cover 10. Next, prepare for firing in the order specified in the [40 mm Hand-held anti-personnel grenade launcher Operating Manual 6G30 RE]. Firing at aerial targets can be carried out from a supine position, kneeling, or standing with the required lead in the event of a moving UAV.

[0034] The hand-held anti-personnel grenade launcher is unloaded in the reverse order of loading. The spent cartridge case in the insert barrels 1 is removed using an extractor or cleaning rod.
