Description

Technical Field

[0001] This utility model relates to the field of ammunition technology, specifically to an anti-drone bullet that can be used in both rifles and machine guns. Background Technology

[0002] With the rapid development of drone technology, drones are increasingly used in both civilian and military fields, but they also bring security threats, especially in scenarios such as counter-terrorism, border monitoring, and military conflicts, where drones have become a potential means of reconnaissance and attack. Therefore, developing efficient counter-drone weapon systems is particularly important.

[0003] While conventional shotgun bullets possess some deterrent effect against drones due to their scattering characteristics, their effectiveness is significantly reduced when facing drones flying at high altitudes or over long distances, making it difficult to achieve an effective strike. Designs exist on the market that connect shot pellets with wire to increase the coverage area and improve the ability to entangle and capture drones. However, this design is still limited by the range of the shotgun itself and fails to fundamentally solve the problem of long-range anti-drone warfare. Because drones are small, fast-flying, and often operate at considerable distances, conventional rifle bullets, due to their accuracy and range limitations, struggle to accurately hit their targets, especially under dynamic tracking and rapid-fire conditions, where the hit rate is even lower. Furthermore, conventional rifle bullets, machine gun bullets, and shotgun bullets are only effective against single or small numbers of drones; existing conventional bullets are insufficient to deal with large swarms of drones. Utility Model Content

[0004] This invention aims to solve the problems of short range and low hit rate of existing anti-drone bullets. By using a built-in gunpowder delayed release mechanism, the effective range and accuracy of the bullet are improved. At the same time, the mesh-like shot structure enhances the ability to entangle and capture drones.

[0005] To solve the above-mentioned technical problems, the technical solution provided by this utility model is: a universal anti-drone bullet for rifles and machine guns, comprising:

[0006] The projectile body is located at the front of the cartridge case and has an internal cavity. The projectile body consists of shot pellets, wire, sabot, gunpowder chamber, fore-powder, ignition agent, and initiator. The sabot is placed inside the cavity of the projectile body and is equipped with multiple shot pellets, which are connected to each other by wire. The gunpowder chamber is located at the rear of the sabot. The gunpowder chamber is filled with fore-powder and the ignition agent behind it. The side of the ignition agent is filled with initiator, and the initiator is connected to the ignition agent.

[0007] The cartridge case contains a rear propellant, one side of which is in contact with the igniter and the other side is in contact with the primer located at the rear of the cartridge case.

[0008] Furthermore, after the rear propellant loaded inside the cartridge case is ignited by the primer at the rear end, the rear propellant ignites the igniter, the igniter ignites the ignition agent, and the ignition agent ignites the front propellant, thereby providing propulsion to the sabot and launching the bullet particles interconnected by wires inside the sabot, forming a scattering mesh-like attack surface, thus trapping and entangled the drone's wings.

[0009] Furthermore, the sabot is a cup-shaped sabot structure.

[0010] Compared with the prior art, the advantages of this utility model are: (1) Increased range: Through the design of built-in propellant, the bullet can be accelerated twice during flight, which significantly improves the effective range, so that rifles and machine guns can also effectively strike drones at a greater distance; (2) Improved hit rate: The shot pellets are connected by wires to form a mesh structure, which not only expands the attack range, but also increases the probability of hitting the drone. Even if a single pellet does not hit directly, the mesh structure can effectively wrap around the drone's wings, thereby capturing or forcing it to fall; (3) Strong adaptability: The bullet design of this solution is compatible with rifles and machine guns, and the anti-drone capability can be improved without changing the weapon system, which enhances the versatility and flexibility of the equipment; (4) The continuous firing of rifles and machine guns can effectively deal with drone swarms, effectively solving the shortcoming that shotguns can only deal with a single drone.

[0014] The present invention will now be described in further detail with reference to the accompanying drawings.

[0015] Example 1

[0016] like Figure 1 and Figure 2As shown, this embodiment provides a rifle / machine gun universal anti-drone bullet, comprising a bullet body and a cartridge case. The bullet body has a cavity containing a composite structure consisting of shot pellets, wire, a sabot, a propellant chamber, a front propellant, and a igniter and initiator. The sabot contains multiple shot pellets connected by wire, forming a mesh structure to increase its ability to entangle and capture drones. The cartridge case is filled with a rear propellant connected to the igniter. When the bullet is fired, the primer ignites the rear propellant, which in turn ignites the front propellant in the propellant chamber within the bullet body via the igniter and initiator, propelling the sabot and shot pellets forward. After a certain distance, the shot pellets are released, forming a scattering mesh attack surface.

[0017] Specifically, this embodiment includes the following core components:

[0018] (1) Projectile 1

[0019] The projectile body 1 is the main body of the bullet, located at the front of the cartridge case 2, and has an internal cavity to accommodate other components. The front end of the projectile body 1 is designed with a sharp shape to reduce air resistance and improve flight stability. The projectile body 1 not only serves as the outer shell of the bullet but also carries key components such as the shot pellets 1-1, the fuse 1-2, the sabot 1-3, the propellant chamber 1-4, the propellant 1-7, the ignition agent 1-5, and the igniter 1-6, collectively enabling the bullet's firing and impact functions. The projectile body 1 is precision-machined to fit tightly with the front end of the cartridge case 2, ensuring the bullet's stability and accuracy during firing.

[0020] The shot pellets 1-1 consist of multiple small metal or hard plastic balls of moderate diameter, designed to effectively entangle the drone's wings without causing excessive damage to the surrounding environment. Shot pellets 1-1 are the primary striking element of the bullet. After the bullet is fired, the wire 1-2, guided by the shot pellets 1-1, forms a mesh structure that entangles and captures the drone. The shot pellets 1-1 are interconnected via the wire 1-2, forming a unified mesh structure, which is then placed within the sabot 1-3.

[0021] Silk thread 1-2 is a high-strength, wear-resistant, and non-breakable synthetic fiber material with a certain degree of elasticity to adapt to the dynamic changes of the bullet particles 1-1 during flight. Silk thread 1-2 not only connects the bullet particles 1-1 to form a mesh structure, but also maintains the relative positions of the bullet particles 1-1 after the bullet is fired, ensuring the stability and effectiveness of the mesh structure. One end of silk thread 1-2 is fixed to the inner wall of the sabot 1-3, while the other end is connected to the bullet particles 1-1, forming a tight network.

[0022] The sabot 1-3 is an open, cup-shaped structure made of lightweight metal, possessing sufficient strength and rigidity to support the pellets 1-1 and the wire 1-2. Before the bullet is fired, the sabot 1-3 serves to fix and support the pellets 1-1, ensuring they do not scatter during flight. When the bullet reaches the predetermined distance, the sabot 1-3 detaches under the thrust generated by the powder chamber 1-4, releasing the pellets 1-1. The sabot 1-3 is precision-machined to fit tightly against the inner wall of the bullet body 1 cavity, ensuring it will not detach or shift during firing. Simultaneously, the rear of the sabot 1-3 connects to the powder chamber 1-4 to receive the thrust.

[0023] The propellant chamber 1-4 is a small, sealed chamber located at the rear of the sabot 1-3, filled with high-efficiency propellant 1-7 and ignition agent 1-5. After the bullet has traveled a certain distance, the propellant chamber 1-4 ignites the propellant 1-7, generating thrust to propel the sabot 1-3 and the shot pellets 1-1 forward, releasing the shot pellets 1-1 at a predetermined distance. The propellant chamber 1-4 is precision-machined to the rear of the sabot 1-3, ensuring that the propellant 1-7 can rapidly transfer thrust upon ignition. Simultaneously, the propellant chamber 1-4 is connected to the propellant 1-7, ignition agent 1-5, and igniter 1-6 to receive ignition signals.

[0024] The ignition transfer agent is a flammable material filled at the rear of the gunpowder chamber 1-4, adjacent to the igniter 1-6. After the igniter 1-6 is ignited, the ignition transfer agent 1-5 burns rapidly, transferring the flame to the front propellant 1-7 within the gunpowder chamber 1-4, thereby igniting the front propellant 1-7 and generating thrust. The ignition transfer agent 1-5 is precisely machined and filled at the rear of the gunpowder chamber 1-4, ensuring close contact with the igniter 1-6 to guarantee ignition efficiency.

[0025] Ignition agent 1-6 is a highly sensitive ignition material, filled between the propellant chamber 1-4 and the rear propellant 2-1 inside the cartridge case 2. After ignition, ignition agent 1-6 burns rapidly in the rear propellant 2-1 inside the cartridge case 2, transferring the flame to the igniter, which in turn ignites the front propellant 1-7 inside the propellant chamber 1-4. Ignition agent 1-6 is precisely machined to fill the space between the propellant chamber 1-4 and the rear propellant 2-1 inside the cartridge case 2, ensuring close contact with both to guarantee ignition efficiency.

[0026] (2) Cartridge Case 2

[0027] The cartridge case 2 is the rear structure of the bullet, made of high-strength metal material with a certain thickness to withstand the pressure and high temperature during firing. The cartridge case 2 has an internal chamber for filling with the breech propellant 2-1 and a primer 2-2 for igniting the breech propellant 2-1. The cartridge case 2 not only serves as the bullet's supporting structure but also supports key components such as the breech propellant 2-1 and primer 2-2. During firing, the cartridge case 2 withstands the pressure and high temperature generated by the combustion of the breech propellant 2-1 and transfers the flame to the igniter 1-6 to ignite the entire bullet system. The cartridge case 2 is precision-machined to fit tightly with the rear of the bullet body 1, ensuring the bullet's stability and accuracy during firing. Simultaneously, the cartridge case 2 is filled with the breech propellant 2-1 and connected to the primer 2-2 to ensure ignition efficiency. One side of the breech propellant 2-1 inside the cartridge case 2 is in contact with the igniter 1-6, and the other side is in contact with the primer 2-2. When the primer 2-2 is fired, the propellant 2-1 burns rapidly and ignites the igniter 1-6, thereby initiating the ignition and firing process of the entire bullet system.

[0028] Example 2

[0029] like Figure 1 and Figure 2 As shown, this embodiment provides a rifle and machine gun compatible anti-drone bullet. Its overall operation combines sophisticated mechanical design with the principle of chemical energy release, aiming to achieve long-range, high-precision drone strikes. The following is a detailed description of the bullet's overall operation:

[0030] I. Preparation Stage

[0031] The bullet consists of two main parts: the bullet body 1 and the cartridge case 2. The bullet body 1 has an internal cavity containing shot pellets 1-1, wire 1-2, a sabot 1-3, a powder chamber 1-4, a propellant 1-7, a igniter 1-5, and a primer 1-6. The cartridge case 2 is filled with a breech propellant 2-1 and connected to a primer 2-2. Before the bullet is loaded into the firearm and ready to fire, all components are in a stable state, and no chemical reaction occurs.

[0032] II. Shooting Phase

[0033] When the firing pin strikes the primer 2-2, the primer 2-2 ignites rapidly, producing a high-temperature flame. The primer 2-2 ignites the propellant 2-1 inside the cartridge case 2, which burns rapidly and generates a large amount of high-pressure gas. This high-pressure gas propels the cartridge case 2 and the entire bullet forward, and also passes through the gap between the cartridge case 2 and the bullet body 1 to the igniter 1-6. Upon receiving the flame generated by the propellant 2-1, the igniter 1-6 burns rapidly and transfers the flame to the ignition medium. The ignition medium continues to transfer the flame to the forecharge 1-7 in the propellant chamber 1-4, where it is ignited and generates a strong thrust.

[0034] III. Release and Strike Phase

[0035] The thrust generated by the gunpowder chamber 1-4 propels the sabot 1-3 and the shot pellets 1-1 forward at high speed. During flight, the sabot 1-3 maintains the relative position of the shot pellets 1-1, ensuring the stability of the mesh structure. When the bullets reach a predetermined distance—which is pre-calculated based on factors such as the drone's altitude, speed, and firing angle—the thrust of the gunpowder chamber 1-4 reaches its peak. Under the influence of the high-speed airflow, the sabot 1-3 detaches or disintegrates, releasing the shot pellets 1-1. Dragged by the wire 1-2, the shot pellets 1-1 form a scattering mesh attack surface, rapidly unfolding and entangling the drone's wings or fuselage. Due to the high kinetic energy and entangling force of the shot pellets 1-1 and the wire 1-2, they can effectively slow down or stop the drone's flight, even causing it to crash.

[0036] IV. Follow-up processing:

[0037] After the bullet completes its mission, the remaining cartridge case 2 and other components may be recovered or disposed of depending on the specific circumstances. The pellets 1-1 and the thread 1-2, after becoming entangled in the drone, may need to be removed manually or by other means.

[0038] In summary, this anti-drone bullet, through a combination of precise mechanical design and the principle of chemical energy release, achieves long-range, high-precision drone strikes. During firing, the various components work together to ensure the bullet's stable flight and effective impact.

[0039] Example 3

[0040] like Figure 1 and Figure 2 As shown, this embodiment provides a rifle / machine gun compatible anti-drone bullet. The bullet body 1 is made of high-strength alloy material with a sharp tip to reduce air resistance. It has an internal cavity containing shot pellets 1-1, high-strength wire 1-2, and a sabot 1-3. The shot pellets 1-1 are multiple small metal balls interconnected by the wire 1-2 to form a mesh structure. The sabot 1-3 is used to fix the shot pellets 1-1 and wire 1-2 in their pre-firing positions. The propellant chamber assembly is located at the rear of the bullet body 1 and includes a propellant chamber 1-4, a front propellant 1-7, a ignition agent 1-5, and a igniter 1-6. The propellant chamber 1-4 is filled with high-efficiency front propellant 1-7, which, along with the ignition agent 1-5 and igniter 1-6, is sequentially connected to transmit the ignition signal. The cartridge case 2 is made of high-strength steel and filled with rear propellant 2-1, which is connected to the primer 2-2. The rear propellant 2-1 is used to generate the high-pressure gas required for firing.

[0041] During firing, the firing pin ignites the primer 2-2, which in turn ignites the propellant 2-1, generating high-pressure gas that propels the cartridge case 2 and the entire bullet forward. Simultaneously, the flame from propellant 2-1 ignites the igniter 1-6 via the ignition path, which in turn ignites the igniter and the forecharge 1-7 within the propellant chamber 1-4. The thrust generated by the propellant chamber 1-4 propels the sabot 1-3 and the shot pellets 1-1 at high speed. Upon reaching a predetermined distance, the sabot 1-3 detaches, releasing the shot pellets 1-1 to form a mesh-like attack surface that entangles and captures the drone.

[0042] Example 4

[0043] like Figure 1 and Figure 2 As shown, this embodiment provides a universal anti-drone bullet for both rifles and machine guns. This embodiment is an improvement on embodiment three, with optimization of the internal cavity structure of the bullet body 1 and an increase in the volume of the gunpowder chambers 1-4 to increase the gunpowder loading, thereby increasing the bullet's initial velocity and range.

[0044] The shot pellets 1-1 can be small spheres or other regular or irregular shapes, made of lightweight, high-strength materials such as titanium or aluminum alloys to reduce bullet weight and increase flight speed. Simultaneously, the surface of the shot pellets 1-1 undergoes a special treatment to increase friction with the drone's surface, improving the entanglement effect. The thread 1-2 is made of high-strength, wear-resistant synthetic fiber materials, such as Kevlar fiber, to improve the thread's fracture strength and durability. The working principle is the same as in Example 3, but the improved bullet has a higher initial velocity and range, as well as stronger entanglement and capture capabilities.

[0045] Example 5

[0046] like Figure 1 and Figure 2 As shown, this embodiment provides a universal anti-drone bullet for both rifles and machine guns. This embodiment further improves upon Embodiment 3 by adding a delayed ignition mechanism to the propellant chamber assembly to control the ignition time of the fore-powder 1-7 within the propellant chamber 1-4. The delayed ignition mechanism can be adjusted according to parameters such as shooting distance and drone speed to ensure that the shot pellets 1-1 are released at the optimal time. The cartridge case 2 uses novel high-strength, lightweight materials, such as titanium alloy or carbon fiber composite materials, to reduce the weight of the cartridge case 2 and improve shooting accuracy. An adhesive substance is coated on the surface of the shot pellets 1-1 to increase adhesion to the drone surface. Simultaneously, the length and density of the wires 1-2 have been optimized to improve the stability and capture efficiency of the mesh structure.

[0047] During firing, the firing pin ignites the primer 2-2, which in turn ignites the propellant 2-1 inside the cartridge case, generating high-pressure gas that propels the cartridge case 2 and the entire bullet forward. A delayed ignition mechanism controls the ignition time of the forecharge 1-7 in the propellant chamber 1-4 according to preset parameters, ensuring that the shot pellets 1-1 are released at the optimal moment. After release, the shot pellets 1-1, guided by the wire 1-2, form a mesh-like attack surface, adhering to the surface of the drone using an adhesive substance for efficient capture.

[0048] Example 6

[0049] like Figure 1 and Figure 2 As shown, this embodiment provides a rifle and machine gun universal anti-drone bullet. This embodiment is an improvement on embodiment three. The shape of the bullet body 1 is reasonably changed, and the volume and internal volume of the bullet body 1 are increased. The internal cavity structure of the bullet body 1 is optimized, the shot density of the bullet 1-1 is increased, and the density and length of the wire 1-2 are increased, thereby increasing the area of ​​the bullet net formed by the bullet 1-1 and the wire 1-2. The volume of the gunpowder chamber 1-4 is increased to increase the gunpowder loading, thereby increasing the bullet's initial velocity and range.

[0050] The shot pellets 1-1 are made of lightweight, high-strength materials, such as titanium alloy or aluminum alloy, to reduce bullet weight and increase flight speed. Simultaneously, the surface of the shot pellets 1-1 undergoes a special treatment to increase friction with the drone's surface, improving the entanglement effect. The thread 1-2 is made of high-strength, wear-resistant synthetic fiber materials, such as Kevlar fiber, to improve the thread's breaking strength and durability. The working principle is the same as in Example 3, but the improved bullet has a higher initial velocity and range, as well as a larger bullet dispersion area and stronger entanglement and capture capabilities.

[0051] The foregoing has shown and described the basic principles and main features of this utility model, as well as its advantages. Those skilled in the art should understand that this utility model is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of this utility model. Various changes and modifications can be made to this utility model without departing from its spirit and scope, and all such changes and modifications fall within the scope of the claimed utility model. The scope of protection of this utility model is defined by the appended claims and their equivalents.
