Ammunition for forming aerial barrage

Abstract

The ammunition is used on a drone interceptor to combat other drones. The ammunition fires a propeller snare. Ammunition comprises multiple charges with separate electric activation for a multiple attack possibility. The rope forms an air barrier from the moment the shot is fired, it allows the target's propeller to become entangled at a short distance. Twisting the rope increases the likelihood of entanglement on the target. The design of the projectile reduces the likelihood of ricochet. Projectile filled with extra length of rope, it increases the likelihood of entangling the target's propeller. The ammunition is attached to the activation unit. The activation unit is attached to the weapon carrier. The low weight of the weapon allows it to be used on small interceptor drone.

Description

[0001] AMMUNITION FOR FORMING AERIAL BARRAGE

[0002] TECHNICAL FIELD

[0003] The invention relates to air defence devices. The device is a multi-barrel cartridge ammunition with electric ignition for forming anti-aircraft aerial barrage by shooting the ropes.

[0004] BACKGROUND

[0005] In the 20th century, many devices were developed to shot down aircraft using rope. For example, publication FR2708728 describes a weapon designed to shoot down low-flying helicopters using projectiles with attached ropes. This weapon is ground-based and heavy. The 21st century has seen the emergence of a large number of light unmanned aerial vehicles. The emergence of targets with different technical characteristics requires the adaptation of known technical solutions to new tasks. Publication EP4339551 describes a drone with an attached rope used to hook another drone. A rope attached to a carrier drone worsens its manoeuvrability and can get caught in the propellers of the carrier drone itself.

[0006] BRIEF SUMMARY

[0007] Ammunition for use on a light unmanned interceptor drone to combat other drones. The ammunition throws rope snare at the target's propeller. The ammunition is a cartridge with multiple barrels and containers. Multiple charges with separate electric activation designed for a multiple attack possibility. The segments of the ropes are partially placed in containers and partially in projectiles. The rope forms an air barrier from the moment the shot is fired, which allows the target's propeller to become entangled at a short distance. Rope is laid in container in the form of spiral. Twisting the rope increases the likelihood of entanglement on the target. The projectile is a hollow capsule of brittle material with a rope attached. When colliding with a propeller, the projectile breaks and absorbs the impact energy to reduces the chance of ricochet. Projectile filled with extra length of rope, it increases the likelihood of entangling the target's propeller. Projectiles and expelling charges are located in the barrels. Electric igniters are soldered to contact pads on the printed circuit board. The printed circuit board is the platform to which the barrels and containers are glued. Cartridge or several cartridges are attached to the activation unit.The activation unit is attached to the weapon carrier. Tests have shown that ammunition with dozens of shots weighs several tens of times less than a target it hits.

[0013] EXAMPLE OF IMPLEMENTATION

[0014] Figure 1 shows the collision of a propeller blade (4) with a projectile capsule (1). Propeller blade (4) moves to the right (5). Projectile (1) with rope (2) is directed from above (3). The end of the rope (2) rotates due to the spiral unfolding. The projectile (1) breaks, the rope (2) fell out of the projectile (1 ).

[0015] Figure 2 shows the assembled weapon. The activation unit (6) is connected to the power source and control signal by a cable (7). Cartridges (9) are fixed on activation unit (6) using fastening screws (8). The activation unit (6) contains electric keys for supply of electric pulses to contact pads (18) of cartridges (9).

[0016] Figure 3 is a view of the cartridge (10) from the target side.

[0017] Figure 4 is a longitudinal section (A-A) of the cartridge (9). Barrel (12) and container (13) are glued to platform (10) and to frame (11). Part of rope (2) is laid in container (13) in the form of spiral. Part of rope (2) is laid in projectile (1). Projectile (1), wad (15) and expelling charge (16) are located in barrel (12). Sealing tape (14) is glued to frame (11). Igniter (17) is made of conductive wire. Wire passes through holes in platform (10) and is soldered to contact pads (18). Platform (10) is made of printed circuit board with cut holes and recesses.

[0018] Action. Voltage is applied to the contact pads (18), the wire (17) melts and ignites the expelling charge (16). Products of ejection charge (16) combustion push wad (15) andprojectile (1). The sealing tape (14) breaks and the projectile (1) flies out of the barrel (12). Projectile (1) pulls the rope (2) from the container (13). The rope (2) from the projectile (1) is completely unwound after the propeller (4) is hooked (Fig. 1 ).

[0019] INDUSTRIAL APPLICABILITY

[0020] The low weight of the weapon allows it to be used on a small interceptor drones. The weapon allows the interceptor drone to attack several times in one flight and go back. The high speed multi-shot weapon is suitable for hunting moving targets. Energy of the target's engine is used to block it, so muzzle energy can be small. Small-caliber ammunition is not dangerous to humans and is classified as pyrotechnics.
