Abstract
Description
Technical Field
[0001] This invention belongs to the field of weapons and ammunition, and relates to anti-drone technology. Specifically, it relates to a multi-functional anti-drone ammunition for rifled firearms, used for anti-drone operations, especially ammunition capable of attacking fiber optic drones while maintaining basic gun-fighting capabilities, thus solving the drone defense capability problem for infantry in the last 100 meters range. Background Technology
[0002] Currently, drones have become the most threatening weapon to soldiers on the battlefield. Traditional methods of countering drones, such as using rapid-fire cannons and lasers, rely too heavily on the platform and cannot provide cover for soldiers or small units at the grassroots level. This grassroots cover is currently provided by shotguns, but this means that soldiers carrying shotguns lack the ability to engage and defend themselves in emergency situations. Alternatively, soldiers may need to carry a shotgun in addition to their assault rifle, increasing their load and reducing their mobility. Furthermore, soldiers need to switch weapons when facing drone attacks or ground unit attacks, further reducing their reaction speed and survivability. Simultaneously carrying and using two types of firearms also increases the burden on logistics and maintenance.
[0003] On the other hand, fiber optic FPV drones are widely used on the battlefield. These drones are immune to radio interference, fly at low altitudes, and are very dangerous. Their weakness lies in the trailing fiber optic cable, and currently, individual soldiers do not have weapons that can counter the fiber optic cable at long range. Current anti-drone munitions mainly follow a shotgun approach, such as (Chen Long, Chen Zhuo, Ma Lin, et al. A special anti-drone ammunition based on standard small-caliber firearms [P]. China: CN223869942U, 2026-02-03.). Although this method provides standard-caliber firearms with shotgun firing capabilities, the gaps between the shot still reduce the drone's hit rate. Furthermore, attacking the light trailed by the drone guided by the fiber optic cable further deprives infantry of long-range combat capabilities in conventional engagements. The second method is the capture net route, such as (Wang Qingxian; Yang Wansen. Drone capture net grenade [P]. China: CN121876758A, 2026-04-17). This method requires the use of a rifle-mounted grenade launcher, which increases the intensity, reduces the reaction speed, and makes it impossible to achieve continuous firing. Summary of the Invention
[0004] To address the shortcomings of existing technologies, this invention proposes a multi-functional anti-drone ammunition for rifled firearms. Specifically, it is a multi-functional weapon ammunition capable of attacking various types of drones while maintaining soldiers' firepower capabilities. The core design concept is as follows: First, detachable blocks are placed around the periphery or bottom of the projectile to pull on thin wires. Utilizing the rotation of the ammunition upon firing, it forms a rotating, outward-opening star-shaped structure upon leaving the barrel, thereby expanding the kill area against drones and entangling their propellers or optical fibers. Second, a hardened core is placed at the center of the projectile. After leaving the barrel, the aforementioned star-shaped structure separates from this core, and the core continues to fly at high speed towards the target directly ahead. Finally, for rifled firearms, the above structure is complete; for smoothbore firearms, a spiral aerodynamic structure can be added to the tail of the projectile to help it rotate during firing. This structure can conform to the aforementioned detachable blocks. In use, infantrymen can install this type of ammunition on their firearms during peacetime, enabling them to engage both drones and enemy forces unexpectedly. Furthermore, with the tactical coordination of infantry units, it can buy infantry time and space to calmly change specialized ammunition and carry out specialized operations.
[0005] To achieve the above objectives, the technical solution adopted by the present invention is as follows: A multi-functional anti-drone munition for use in rifled weapons, the multi-functional anti-drone munition is composed of the following parts: multiple centrifugal bodies 4, multiple cutting ropes 3, a tethering support 2, and a single kill core 1.
[0006] The lethal core 1 is located at the center of the main body of the ammunition. Its structure is as follows: the head is streamlined, and its shape is consistent with the front end of a conventional projectile; the tail is thinner than the tail of a conventional projectile, and can be a conical or cylindrical isoaxial symmetrical structure, coaxial with the projectile. The connection between the head and the tail forms a locking structure.
[0007] The tether holder 2 is located at the bottom of the lethal projectile core 1, and the two are not interconnected; it is only placed at the bottom of the lethal projectile core 1 during assembly. It can be a rigid cylinder or a spherical, conical, or equiaxed symmetrical structure. The outer periphery of the tether holder 2 is connected to multiple cutting ropes 3, and the bottom of the cutting ropes 3 is evenly connected to its side. The tether holder 2 is coaxially arranged with the lethal projectile core 1.
[0008] Furthermore, the top of the tether holder 2 is provided with a groove that is adapted to the tail end of the killing single core 1.
[0009] The cutting rope 3 is inelastic, has a rough and sharp surface, is connected to the rope support 2 at the bottom and to the upper end of the centrifuge body 4 at the top. Before launch, the cutting rope 3 is stored around the tail of the kill single core 1.
[0010] The centrifuge body 4: Each centrifuge body 4 is a smooth curved hard shell structure. After multiple centrifuge bodies 4 are spliced and combined, their outer surfaces form a streamlined structure with the outer surface of the head of the single-core lethal agent 1. After assembly, the interior has a hollow structure coaxially arranged with the tether support 2 and the single-core lethal agent 1 to accommodate the tail of the single-core lethal agent 1 and the tether support 2. The tether support 2 is located at the bottom opening of the assembled structure. Adjacent centrifuge bodies 4 are not connected to each other, nor are they connected to the lethal projectile core 1. The bottom of the centrifuge body 4 is fixed by a conventional cartridge case 5, and the top shape is adapted to the latch structure, that is, the top is fixed by the latch structure of the head of the single-core lethal agent 1, so that the geometric shape formed by it and the lethal projectile core is consistent with that of a conventional ammunition warhead.
[0011] The specific working principle and innovations of this invention are as follows: During firing, in the acceleration phase within the barrel, the internal ballistic characteristics of the multi-functional anti-drone munition are no different from those of a conventional warhead. As the warhead passes through structures such as the gas port, suppressor, and flash hider, its velocity decreases, and the fragmentation core 1 begins to tend to eject from the centrifugal body 4 shell due to inertia. After exiting the barrel, due to the loss of barrel constraint, the centrifugal body 4 shell is pushed to the periphery, while the fragmentation core 1 continues to fly forward according to inertia, performing a conventional killing function similar to that of a conventional warhead. After being pushed to the periphery, the aerodynamic shape of the centrifugal body 4 shell is disrupted, and under the action of air resistance, it becomes unstable and flies to the periphery. Due to the rifling inside the barrel, the projectile is now rotating at high speed, and the centrifugal body 4 is flung to the periphery under the action of centrifugal force. The cutting rope 2 is pulled to the periphery by the centrifugal body. Thus, the centrifugal body 4, the cutting rope 3, and the tether holder 2 form a rotating, forward-flying star-shaped topology. Whether it's the centrifugal force 4, the tether holder 2, or the single-core killer 1, any hard component that attacks the drone body or the tethered optical fiber can cause effective damage. Simultaneously, the high-speed cutting rope 3 can sever the communication optical fiber during flight, rendering the drone inoperable, or entangle / damage the drone's propellers, also achieving the effect of disabling it.
[0012] The beneficial effects of this invention are as follows: (1) First, it borrows the structure of the fin-stabilized discarding sabot armor-piercing projectile, so that the core in the middle can still maintain a certain conventional combat capability, while not wasting the hardware structure of the surrounding shell, making it a centrifugal body of the anti-drone structure.
[0013] (2) Secondly, during the process of the outer casing detaching, the wind resistance structure of the traditional fin-stabilized discarding sabot armor-piercing projectile is not used. Instead, the separation is effectively completed by utilizing the deceleration phase at the end of the internal ballistic trajectory of the gas-operated gun. This makes the shape of the projectile consistent with that of a conventional projectile, and automatic loading and automatic firing can be achieved through the feeding ramp of conventional firearms.
[0014] (3) Furthermore, it combines the ammunition structure of chain shot and net guns from the era of sailing warships, so that the centrifugal body, thin rope support, and cutting rope together form a rotating forward star-shaped anti-drone structure. This structure has a higher hit rate than chain shot, a faster flight speed than capture nets, increases anti-drone efficiency, and can destroy towed optical fibers.
[0015] In summary, this invention enables munitions to simultaneously possess anti-drone and conventional anti-infantry combat capabilities. It improves the hit rate against drones and effectively destroys fiber-optic drones. Compared to conventional capture nets or shotguns, it enables continuous automatic firing.

[0018] To make the objectives, technical solutions, and advantages of the embodiments of the present invention clearer, the technical solutions of the embodiments of the present invention will be clearly and completely described below with reference to the accompanying drawings. Obviously, the described embodiments are only some embodiments of the present invention, not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.
[0019] A multi-functional anti-drone munition for use with rifled weapons, such as Figure 1 As shown, the multi-functional anti-drone munition includes multiple centrifugal bodies 4, multiple cutting ropes 3, a tether holder 2, and a single kill core 1.
[0020] The lethal core 1 is made of lead and is located in the central part of the ammunition. Its structure is as follows: the head is streamlined, and its shape is consistent with the front end of a conventional projectile; the tail is thinner than the tail of a conventional projectile (the diameter is 3mm in this embodiment), and it is cylindrical in this embodiment, coaxial with the projectile. The head and tail are connected by a tenon structure.
[0021] The tether holder 2 is located at the bottom of the lethal projectile core 1, and the two are not interconnected; it is only placed at the bottom of the lethal projectile core 1 during assembly. In this embodiment, it is a rigid cylinder with a groove on its surface that matches the tail end of the lethal projectile core 1. The outer periphery of the tether holder 2 is connected to four cutting ropes 3, with the bottom of each cutting rope 3 evenly connected to its side. The tether holder 2 is coaxially arranged with the lethal projectile core 1.
[0022] The cutting rope 3 is inelastic and has a rough and sharp surface. In this embodiment, it is a basalt fiber rope coated with glass powder. Its bottom is connected to the rope support 2 and its top is connected to the upper end of the centrifuge body 4. Before launch, the cutting rope 3 is stored around the tail of the kill single core 1.
[0023] The centrifuge body 4: Each centrifuge body 4 is a smooth curved hard shell structure. In this embodiment, it is a smooth curved aluminum shell structure. After the four centrifuge bodies 4 are spliced and combined, their outer surfaces form a streamlined structure with the outer surface of the head of the kill core 1. After assembly, the interior has a hollow structure coaxially arranged with the tether support 2 and the kill core 1 to accommodate the tail of the kill core 1 and the tether support 2. The tether support 2 is located at the bottom opening of the assembled structure. Adjacent centrifuge bodies 4 are not connected to each other, nor are they connected to the kill core 1. The bottom of the centrifuge body 4 is fixed by a conventional cartridge case 5, and the top is fixed by a latch structure at the head of the kill core 1, so that the geometric shape formed by it and the kill core is consistent with that of a conventional ammunition warhead.
[0024] The above-described embodiments are merely illustrative of the implementation methods of the present invention, but should not be construed as limiting the scope of the present invention. It should be noted that those skilled in the art can make several modifications and improvements without departing from the concept of the present invention, including but not limited to adjusting the shape of the nuclear centrifuge body according to actual needs, and adjusting the number of centrifuge bodies and cutting ropes. As long as the working principle of rotating and cutting the target and separating the killing single core remains unchanged, these are all within the protection scope of the present invention.
