Description

[0001] The utility model relates to devices for throwing nets (net launchers), in particular to ammunition (projectiles) for hand-held net launchers and / or unmanned aerial vehicles that use the energy of a gas generator to eject loads and deploy the net.

[0002] The claimed utility model is designed to intercept and neutralize unmanned aerial vehicles (hereinafter referred to as UAVs) and can be used both in combat zones and when protecting civilian facilities.

[0003] STATE OF THE ART

[0004] Public patent PL 246724 B1, "A projectile projectile" is known from the prior art. This source describes a projectile consisting of four main elements: a warhead, a fuse, and a stabilizer with folding stabilizers. The warhead has a larger diameter than the stabilizer, the diameter of which corresponds to the caliber of the launcher barrel. The warhead contains a propelling system for ejecting a net during the projectile's flight, connected electrically, mechanically, or pyrotechnically to a fuse with a programmable response time.

[0005] The disadvantage of the known solution is the complexity of its design (https: / / uprp.gov.pl / pl).

[0006] Another analogue of the claimed solution is utility model RU 212898 "Net Throwing Cartridge". From this source, a net throwing cartridge is known, comprising a supporting body, adapted for connection to a launcher, a net laying, installed in a cavity formed in the front part of the body, the net laying along the perimeter is provided with a ring cable and weights connected to the cable by slings, the supporting body is made of plastic, along the outer generatrix of the supporting body at an acute angle to the longitudinal axis of the body, grooves are made in which unitary cartridges are placed, adapted for electrical initiation from the launcher, in which guide channels are located, the guide channels contain electric igniters and can be equipped with propelling charges and wads, the said weights are installed in the front parts of the guide channels and are configured to be ejected from the cartridges.

[0007] The disadvantage of the known solution is its complexity and unreliability. This patent is the closest analogue to the claimed solution (https: / / www1.fips.ru).

[0008] DISCLOSURE OF UTILITY MODEL

[0009] The technical objective of the claimed utility model is to develop a projectile design for a net launcher that increases its reliability.

[0010] The stated task is achieved by making the net launcher projectile out of plastic, manufactured using the 3D printing method, with a side rectangular container for the net and bypasses in the gas channels.

[0011] The net launcher projectile is manufactured as a single, monolithic plastic structure, completely 3D printed. This manufacturing method ensures low cost and allows for rapid, small-scale production. In this particular case, the net launcher projectile is cast.

[0012] The net launcher projectile has a rectangular body and a side-mounted net container, making it easier to transport and store than traditional projectiles (cylindrical or conical). The rectangular projectile takes up less space and can be more compactly stored and transported, allowing you to carry more net launcher projectiles at once.

[0013] The net launcher projectile includes the following main parts:

[0014] The projectile body is the main body, made of plastic and rectangular in shape. Inside are the gas chamber, four inclined channels for the payload, and a rectangular side container for the net.

[0015] Adapter - secures the gas generator to the starting device. The adapter has a bayonet mount.

[0016] Press-fit bushing - pressed into the adapter, ensures tightness and rigidity of the gas generator fit.

[0017] Projectile Housing Cover - Fits flush into the top of the projectile housing, preventing the net container from being accidentally opened.

[0018] Cargo - each cargo consists of:

[0019] The load body is a tubular part with outer rings that precisely match the channel diameter. The rings act as centering belts and significantly reduce friction during movement.

[0020] Weight - a steel or heavy polymer core that provides the required mass.

[0021] Weight nut and hot melt adhesive - for securely fixing the core inside the weight body.

[0022] Each cargo flow channel is equipped with bypasses, which prevent the formation of back pressure when the gas generator is initiated and ensure stable and simultaneous release of all four cargoes.

[0023] The gas generator with electric igniter is screwed into an adapter molded into a plastic housing. The net is compactly stored in a rectangular side container and tied to four weights. The rectangular container allows for easier and more secure net placement, increasing the likelihood of its full deployment in the air.

[0024] Working principle

[0025] 1. The projectile is mounted on the launcher (hand-held net launcher or drone) using a bayonet mount and secured by turning until it stops.

[0026] 2. The gas generator is screwed into the adapter.

[0027] 3. Electrical power is supplied to the gas generator electric igniter.

[0028] 4. The gas generator is activated, releasing gas under high pressure. The gas enters the central gas chamber and is evenly distributed through four channels.

[0029] 5. The gas pulse simultaneously ejects the cargo from the channels, knocking out the lid and pulling the net stored in the side container. The net fully unfolds in mid-air.

[0040] IMPLEMENTATION OF A UTILITY MODEL

[0041] The net launcher projectile is a monolithic plastic structure, completely printed on a 3D printer. In this particular case, the net launcher projectile is manufactured using a casting method. The net launcher projectile has a rectangular body (1) and a side-mounted container for the net (5). The net launcher projectile includes the following main parts: projectile body (1), adapter (3), press-fit bushing, projectile body cover (2), and weight (4). Inside the projectile body (1) is a gas chamber, four inclined channels for the ejection of weights, and a side rectangular container for the net (5). The adapter (3) has a bayonet mount. The projectile body cover (2) is inserted flush into the top of the projectile body.

[0042] The weight (4) consists of a weight housing, the weight itself, and securing elements. The weight housing is a tubular part with outer rings that precisely match the diameter of the channels. Bypasses are located in each weight channel, preventing back pressure from building up during gas generator activation and ensuring stable and simultaneous release of all four weights.
