Abstract
Description
Technical Field
[0001] The present invention relates to the technical field of ammunition, and in particular to an anti-UAV bullet which is universal for rifles and machine guns. Background Art
[0002] With the rapid development of drone technology, drones are increasingly used in civil 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 potential means of reconnaissance and attack. Therefore, it is particularly important to develop an efficient anti-drone weapon system.
[0003] Ordinary shotgun bullets have a certain deterrent effect on drones in certain situations due to their scattering characteristics, but due to their short range, when facing drones flying at high altitudes or long distances, their effectiveness is greatly reduced, and it is difficult to achieve the purpose of effective strikes. There are designs on the market that connect shotgun pellets with silk threads, aiming to increase the coverage of the pellets 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. Due to the small size, high flight speed, and often long-distance activities of drones, ordinary rifle bullets are difficult to accurately hit the target due to accuracy and range limitations, especially under dynamic tracking and rapid shooting conditions, the hit rate is even lower, and ordinary rifle bullets, machine gun bullets and shotgun bullets can only have a certain restraining effect on a single drone or a small number of drones, and it is difficult for existing ordinary bullets to cope with a large number of drone swarms. Summary of the invention
[0004] The present invention aims to solve the problems of short range and low hit rate of existing anti-UAV bullets. The effective range and striking accuracy of the bullets are improved through a built-in gunpowder delayed release mechanism. At the same time, the mesh scattered projectile structure is used to enhance the entanglement and capture capabilities of UAVs.
[0005] In order to solve the above technical problems, the present invention provides a technical solution: an anti-UAV bullet universal for rifles and machine guns, comprising:
[0006] The projectile body is arranged at the front of the cartridge case and has a cavity inside. The projectile body is composed of scattered projectiles, silk threads, a sabot, a gunpowder chamber, a pyrotechnic agent, and an igniter. The sabot is placed in the cavity of the projectile body, and a plurality of scattered projectiles are mounted on the sabot. The scattered projectiles are connected to each other by silk threads. A gunpowder chamber is arranged at the rear of the sabot, and the gunpowder chamber is filled with a pyrotechnic agent, and the igniter is filled on the side of the pyrotechnic agent.
[0007] The cartridge case is filled with gunpowder, one side of the gunpowder is in contact with the ignition agent, and the other side is in contact with the primer filled at the rear end of the cartridge case.
[0008] Furthermore, after the gunpowder filled in the cartridge case is ignited by the primer at the rear end, the gunpowder ignites the ignition agent, and the ignition agent ignites the ignition transfer agent, thereby providing propulsion to the cartridge case, launching the scattered projectiles interconnected by silk threads in the cartridge case, forming a scattered mesh attack surface, thereby entangling and entangled the UAV's flying wings.
[0009] Furthermore, the spring support is a cup-shaped spring support structure.
[0010] Compared with the prior art, the advantages of the present invention are: (1) increasing the range: through the design of built-in gunpowder, the bullet can be accelerated twice during flight, which significantly increases the effective range, so that rifles and machine guns can also effectively attack drones at a longer distance; (2) improving the hit rate: the shotgun pellets are connected by silk threads 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 bullet does not hit directly, the mesh structure can effectively entangle the drone's wings to capture it or force it to fall; (3) strong adaptability: the bullet design of this scheme is compatible with rifles and machine guns, and the anti-drone capability can be improved without changing the weapon system, thereby enhancing the versatility and flexibility of the equipment; (4) the continuous shooting of rifles and machine guns can effectively deal with drone swarms, effectively solving the shortcoming that shotguns can only deal with single drones.

[0014] The present invention is further described in detail below in conjunction with the accompanying drawings.
[0015] Embodiment 1
[0016] like Figure 1 and Figure 2As shown, this embodiment provides an anti-UAV bullet that is universal for rifles and machine guns, including a projectile body and a cartridge case. A cavity is provided in the projectile body, which is equipped with a composite structure consisting of scattered projectiles, silk threads, a cartridge case, a gunpowder chamber, a pyrotechnic agent and an igniter. The cartridge case is loaded with a plurality of scattered projectiles connected by silk threads to form a mesh structure to increase the ability to entangle and capture UAVs. The cartridge case is filled with gunpowder and connected to the igniter. When the bullet is fired, the primer ignites the gunpowder, and then the pyrotechnic agent and the pyrotechnic agent ignite the gunpowder chamber in the projectile body, pushing the cartridge case and the scattered projectiles to fly forward, and releasing the scattered projectiles after a certain distance to form a scattered mesh attack surface.
[0017] Specifically, this embodiment includes the following core components:
[0018] (1) Projectile 1
[0019] The projectile 1 is the main part of the bullet, which is arranged at the front of the shell 2, and has a cavity inside to accommodate other components. The front end of the projectile 1 is designed to be sharp to reduce air resistance and improve flight stability. The projectile 1 not only serves as the shell of the bullet, but also carries key components such as the scattered projectile 1-1, silk thread 1-2, bullet support 1-3, gunpowder chamber 1-4, ignition agent 1-5 and ignition agent 1-6, which together realize the firing and striking functions of the bullet. The projectile 1 is closely matched with the front end of the shell 2 through precision machining to ensure the stability and accuracy of the bullet during shooting.
[0020] The scattered pellets 1-1 are multiple small metal balls or hard plastic balls with a moderate diameter to ensure that they can effectively wrap around the wings of the drone without causing excessive damage to the surrounding environment. The scattered pellets 1-1 are the main striking element of the bullet. When the bullet is fired, the silk thread 1-2 forms a mesh structure under the traction of the scattered pellets 1-1, wrapping around and capturing the drone. The scattered pellets 1-1 are connected to each other by the silk thread 1-2 to form an overall mesh structure, which is placed in the bullet support 1-3.
[0021] The thread 1-2 is a synthetic fiber material with high strength, wear resistance and difficulty in breaking, and has a certain elasticity to adapt to the dynamic changes of the scattered projectiles 1-1 during flight. The thread 1-2 not only connects the scattered projectiles 1-1 to form a mesh structure, but also maintains the relative positions between the scattered projectiles 1-1 after the bullet is fired, ensuring the stability and effectiveness of the mesh structure. One end of the thread 1-2 is fixed to the inner wall of the bullet support 1-3, and the other end is connected to the scattered projectiles 1-1 to form a tight network.
[0022] The sabot 1-3 is a cup-shaped structure with an opening, made of a light metal material, and has a certain strength and rigidity to support the scattered projectiles 1-1 and the silk thread 1-2. The sabot 1-3 plays a role in fixing and supporting the scattered projectiles 1-1 before the bullet is fired, ensuring that the scattered projectiles 1-1 will not scatter during flight. When the bullet reaches a predetermined distance, the sabot 1-3 falls off under the thrust generated by the gunpowder chamber 1-4, releasing the scattered projectiles 1-1. The sabot 1-3 is closely matched with the inner wall of the cavity of the projectile body 1 through precision machining to ensure that it will not fall off or shift during the shooting process. At the same time, the rear part of the sabot 1-3 is connected to the gunpowder chamber 1-4 to receive the thrust.
[0023] The gunpowder chamber 1-4 is a small closed chamber located at the rear of the sabot 1-3 and filled with high-efficiency gunpowder. The gunpowder chamber 1-4 ignites the gunpowder at a certain distance after the bullet is fired, generating thrust to push the sabot 1-3 and the scattered projectile 1-1 forward, and releases the scattered projectile 1-1 at a predetermined distance. The gunpowder chamber 1-4 is connected to the rear of the sabot 1-3 through precision machining to ensure that the gunpowder can quickly transmit thrust when ignited. At the same time, the gunpowder chamber 1-4 is connected to the ignition agent 1-5 and the ignition agent 1-6 to receive the ignition signal.
[0024] The ignition transfer agent 1-5 is a flammable material filled in the side of the gunpowder chamber 1-4 and adjacent to the igniter 1-6. The ignition transfer agent 1-5 burns rapidly after the igniter 1-6 is ignited, and transmits the flame to the gunpowder in the gunpowder chamber 1-4, thereby igniting the gunpowder and generating thrust. The ignition transfer agent 1-5 is filled in the side of the gunpowder chamber 1-4 through precision processing, and is in close contact with the igniter 1-6 to ensure ignition efficiency.
[0025] The igniter 1-6 is a highly sensitive ignition material, which is filled between the gunpowder chamber 1-4 and the gunpowder 2-1 in the cartridge case 2. The igniter 1-6 burns rapidly after the gunpowder 2-1 in the cartridge case 2 is ignited, and transmits the flame to the ignition transfer agent 1-5, thereby igniting the gunpowder in the gunpowder chamber 1-4. The igniter 1-6 is filled between the gunpowder chamber 1-4 and the gunpowder 2-1 in the cartridge case 2 through precision processing, and is in close contact with both to ensure ignition efficiency.
[0026] (2) Shell 2
[0027] The cartridge case 2 is the rear structure of the bullet, which is made of high-strength metal material and has a certain thickness to withstand the pressure and high temperature during shooting. The cartridge case 2 is provided with a chamber for filling gunpowder 2-1, and a primer 2-2 is provided for igniting the gunpowder. The cartridge case 2 not only serves as the supporting structure of the bullet, but also carries key components such as gunpowder 2-1 and primer 2-2. During the shooting process, the cartridge case 2 withstands the pressure and high temperature generated by the combustion of gunpowder, and transmits the flame to the igniter 1-6 to ignite the entire bullet system. The cartridge case 2 is closely matched with the rear of the projectile body 1 through precision machining to ensure the stability and accuracy of the bullet during shooting. At the same time, the cartridge case 2 is filled with gunpowder 2-1 and connected to the primer 2-2 to ensure ignition efficiency. One side of the gunpowder 2-1 contacts the igniter 1-6, and the other side contacts the primer 2-2. When the primer 2-2 is fired, the gunpowder 2-1 burns rapidly and ignites the igniter 1-6, thereby triggering the ignition and firing process of the entire bullet system.
[0028] Embodiment 2
[0029] like Figure 1 and Figure 2 As shown, this embodiment provides an anti-UAV bullet that is universal for rifles and machine guns. Its overall working method combines precise mechanical design with the principle of chemical energy release, aiming to achieve long-range, high-precision UAV strikes. The following is a detailed description of the overall working method of the bullet:
[0030] 1. Preparation
[0031] The bullet consists of two parts: the body 1 and the shell 2. The body 1 has a cavity inside, which is loaded with a shot 1-1, a thread 1-2, a butt 1-3, a gunpowder chamber 1-4, a ignition agent 1-5 and an ignition agent 1-6. The shell 2 is filled with gunpowder 2-1 and is connected to the primer 2-2. Before the bullet is loaded into a firearm and is ready to be fired, all components are in a stable state and no chemical reaction occurs.
[0032] 2. Shooting Phase
[0033] When the firing pin of the firearm hits the primer 2-2, the primer 2-2 burns rapidly and generates a high-temperature flame. The primer 2-2 ignites the gunpowder 2-1 in the cartridge case 2, and the gunpowder 2-1 burns rapidly and generates a large amount of high-pressure gas. This part of high-pressure gas, on the one hand, pushes the cartridge case 2 and the entire bullet forward, and on the other hand, it is transferred to the igniter 1-6 through the gap between the cartridge case 2 and the projectile body 1. After receiving the flame generated by the gunpowder 2-1, the igniter 1-6 burns rapidly and transfers the flame to the ignition transfer agent 1-5. The ignition transfer agent 1-5 continues to transfer the flame to the gunpowder in the gunpowder chamber 1-4, at which time the gunpowder in the gunpowder chamber 1-4 is ignited and generates a strong thrust.
[0034] 3. Release and Strike Phase
[0035] The thrust generated by the gunpowder chamber 1-4 pushes the sabot 1-3 and the scattered pellets 1-1 to fly forward at high speed. During the flight, the sabot 1-3 maintains the relative position between the scattered pellets 1-1 to ensure the stability of the mesh structure. When the bullet flies to a predetermined distance, the distance is pre-calculated according to factors such as the height, speed and shooting angle of the drone, the thrust of the gunpowder chamber 1-4 reaches a peak value, and the sabot 1-3 falls off or disintegrates under the action of the high-speed airflow, releasing the scattered pellets 1-1. The scattered pellets 1-1 form a scattered mesh attack surface under the traction of the silk thread 1-2, which quickly unfolds and entangles the wings or fuselage of the drone. Since the scattered pellets 1-1 and the silk thread 1-2 have high kinetic energy and entanglement force, they can effectively slow down or prevent the flight of the drone, and even cause the drone to fall.
[0036] 4. Subsequent processing:
[0037] After the bullet completes the strike mission, the remaining shell 2 and other components may be recovered or processed according to the specific situation. After the scattered bullet 1-1 and the silk thread 1-2 are entangled with the drone, they may need to be cleaned up by manual or other means.
[0038] In summary, the anti-UAV bullet of this scheme achieves long-range and high-precision UAV strikes through the combination of precise mechanical design and chemical energy release principle. During the shooting process, various components work together to ensure the stable flight and effective strike of the bullet.
[0039] Embodiment 3
[0040] like Figure 1 and Figure 2 As shown, this embodiment provides an anti-UAV bullet that is universal for rifles and machine guns. The projectile body 1 is made of high-strength alloy material, and the front end is sharp to reduce air resistance. A cavity is provided inside, which is loaded with scattered projectiles 1-1, high-strength silk thread 1-2 and bullet support 1-3. The scattered projectiles 1-1 are multiple small metal balls, which are connected to each other by silk thread 1-2 to form a mesh structure. The bullet support 1-3 is used to fix the position of the scattered projectiles 1-1 and the silk thread 1-2 before firing. The gunpowder chamber assembly is located at the rear of the projectile body 1, including a gunpowder chamber 1-4, a fire transfer agent 1-5 and an ignition agent 1-6. The gunpowder chamber 1-4 is filled with high-efficiency gunpowder, and the fire transfer agent 1-5 and the ignition agent 1-6 are connected in sequence for transmitting the ignition signal. The cartridge case 2 is made of high-strength steel, filled with gunpowder 2-1 inside, and connected to the primer 2-2. The gunpowder 2-1 is used to generate the high-pressure gas required for shooting.
[0041] When shooting, the firing pin of the firearm fires the primer 2-2, ignites the gunpowder 2-1, and generates high-pressure gas to push the cartridge case 2 and the entire bullet forward. At the same time, the flame generated by the gunpowder 2-1 ignites the ignition agent 1-6 through the fire transmission path, and then ignites the ignition agent 1-5 and the gunpowder in the gunpowder chamber 1-4. The thrust generated by the gunpowder chamber 1-4 pushes the sabot 1-3 and the scattered projectile 1-1 to fly at high speed. When flying to a predetermined distance, the sabot 1-3 falls off, releasing the scattered projectile 1-1 to form a mesh attack surface, entangle and capture the drone.
[0042] Embodiment 4
[0043] like Figure 1 and Figure 2 As shown, this embodiment provides an anti-UAV bullet that is universal for rifles and machine guns. This embodiment is improved on the basis of the third embodiment, the internal cavity structure of the projectile body 1 is optimized, and the volume of the gunpowder chamber 1-4 is increased to increase the gunpowder loading amount, thereby increasing the initial velocity and range of the bullet.
[0044] The shot 1-1 is made of light and high-strength materials, such as titanium alloy or aluminum alloy, to reduce the weight of the bullet and increase the flight speed. At the same time, the surface of the shot 1-1 is specially treated to increase the friction with the surface of the drone and improve the winding effect. The silk thread 1-2 is made of high-strength, wear-resistant synthetic fiber material, such as Kevlar fiber, to improve the breaking strength and durability of the silk thread. The working principle is the same as that of Example 3, but the improved bullet has a higher initial velocity and range, as well as stronger winding and capturing capabilities.
[0045] Embodiment 5
[0046] like Figure 1 and Figure 2 As shown, this embodiment provides an anti-UAV bullet that is universal for rifles and machine guns. This embodiment is further improved on the basis of Example 3, and a delayed ignition mechanism is added to the gunpowder chamber assembly to control the ignition time of the gunpowder in the gunpowder chamber 1-4. The delayed ignition mechanism can be adjusted according to parameters such as shooting distance and UAV speed to ensure that the scattered projectile 1-1 is released at the best time. The shell 2 adopts a new type of high-strength and lightweight material, such as titanium alloy or carbon fiber composite material, to reduce the weight of the shell 2 and improve shooting accuracy. The surface of the scattered projectile 1-1 is coated with a sticky substance to increase the adhesion to the surface of the UAV. At the same time, the length and density of the silk thread 1-2 are optimized to improve the stability and capture efficiency of the mesh structure.
[0047] When shooting, the firing pin of the firearm fires the primer 2-2, ignites the gunpowder 2-1, and generates high-pressure gas to push the cartridge case 2 and the entire bullet forward. The delayed ignition mechanism controls the ignition time of the gunpowder in the gunpowder chamber 1-4 according to the preset parameters to ensure that the scattered projectile 1-1 is released at the best time. After being released, the scattered projectile 1-1 forms a mesh attack surface under the traction of the silk thread 1-2, and uses a sticky substance to adhere to the surface of the drone to achieve efficient capture.
[0048] Embodiment 6
[0049] like Figure 1 and Figure 2 As shown, the present embodiment provides an anti-UAV bullet that is universal for rifles and machine guns. The present embodiment is improved on the basis of the third embodiment, the shape of the projectile body 1 is reasonably changed, the volume of the projectile body 1 is increased, and the internal volume of the projectile body 1 is increased, the internal cavity structure of the projectile body 1 is optimized, the shot density of the projectile 1-1 is increased, the density and length of the silk thread 1-2 are increased, thereby increasing the area of the bullet net composed of the shot 1-1 and the silk thread 1-2; the volume of the gunpowder chamber 1-4 is increased to increase the gunpowder loading amount, thereby increasing the initial velocity and range of the bullet.
[0050] The shot 1-1 is made of light and high-strength materials, such as titanium alloy or aluminum alloy, to reduce the weight of the bullet and increase the flight speed. At the same time, the surface of the shot 1-1 is specially treated to increase the friction with the surface of the drone and improve the winding effect. The silk thread 1-2 is made of high-strength, wear-resistant synthetic fiber material, such as Kevlar fiber, to improve the breaking strength and durability of the silk thread. The working principle is the same as that of Example 3, but the improved bullet has a higher initial velocity and range, as well as a larger net spread area and stronger winding and capture capabilities.

Those skilled in the art should understand that the present invention is not limited to the above embodiments.
