AI Technical Summary

Technical Problem

Existing kinetic energy non-lethal weapons lack sufficient accuracy and stability. Rubber bullets are prone to deformation and ricochet, while metal bullets are easily penetrated or shattered and are difficult to manufacture into non-lethal weapons. Existing deformable bullets concentrate energy, resulting in excessive local damage and poor adaptability.

Method used

The projectile features a lead-antimony alloy core with 10-13% antimony and a brass jacket. The front end of the projectile core is equipped with a trumpet-shaped deactivation pit and a circumferential pre-splitting deactivation rib. After hitting a soft target, the projectile gradually expands into a planar flower shape. The pre-splitting deactivation rib tears open the jacket, forming a surface contact state and reducing the risk of penetration.

Benefits of technology

It improves shooting accuracy and stability, expands the impact area, rapidly disables soft targets, reduces the risk of excessive penetration, and has strong adaptability.

Description

TECHNICAL FIELD

[0001] The utility model belongs to non-lethal weapons, more particularly to short-range kinetic energy expansion type disable riot warhead for anti-terrorist riot. BACKGROUND

[0002] Non-lethal weapons are essential choices for military and civilian departments to carry out anti-terrorism, riot control, security and other diversified tasks. In the escalation of force procedures, non-lethal weapons provide an effective transition from verbal warnings to lethal force, fundamentally changing the traditional combat style. Non-lethal weapons are an effective complement to traditional lethal weapons.

[0003] Non-lethal weapons include chemical, kinetic, acousto-optic, electromagnetic and other types. Kinetic non-lethal weapons are the earliest to develop and the most widely used. Kinetic non-lethal weapons have gone through the development stages of steel core rubber coating kinetic energy bullets, rubber bullets, wooden stick bullets, plastic stick bullets, rubber bullets, and cloth bag bullets. Currently, rubber bullets are more commonly used. Although rubber bullets have good performance in terms of cost and performance, the volume of rubber bullet heads is usually larger than that of metal bullet heads, making them susceptible to wind resistance, gravity and other factors, resulting in lower shooting accuracy. In addition, due to their soft material, rubber bullet heads are prone to deformation and rebound, posing a greater risk of ricochet. Although metal bullet heads have higher shooting accuracy, they are often made of lead, lead-antimony alloy, or steel. Lead is too soft, and the bullet heads made of it are prone to cracking and dispersing, making it difficult to treat when fragments enter the human body. Lead-antimony alloy is more flexible and is often used to make lethal weapons. For example, in 1784, British General Henry Shrapnel developed a spherical bullet head made of a lead alloy containing 10-13% antimony. The shrapnel bomb using this alloy bullet head is more likely to break upon explosion, thereby enhancing its lethality. However, there are currently no non-lethal weapons made of lead-antimony alloy. Steel is too hard, and the bullet heads made of it are prone to penetrating the human body, causing fatal injuries. Therefore, it is very difficult to make non-lethal weapons from metal bullet heads.

[0004] In view of the above problems, the patent document CN116997766A discloses a deformed bullet for ammunition of police and other governing agencies, which discloses an iron-based material hollow tip bullet, and forms a deformed bullet based on the same. The nose portion of the deformed bullet has a central cavity, and the outer side of the nose portion has at least one weakened section oriented in the circumferential direction, in particular, the complete circumference. The weakened section forms a predetermined bending point, and when the deformed bullet hits the target, the nose wall bends radially outward at the predetermined bending point, so that the bullet expands to form a complete mushroom shape, thereby more reliably avoiding penetration of, for example, a protective vest. However, in actual use, the scheme has some problems: the bullet expands into a mushroom shape, which mainly relies on the head expansion to increase the contact area with the target, and the energy transmission is mainly concentrated in the expanded part of the front end of the bullet. Energy concentration can cause excessive local damage, has a high risk of penetration, and has poor adaptability to complex targets; the bullet lacks a protective shell, and the shooting accuracy and stability are easily affected and susceptible to environmental factors. Utility model content

[0005] The utility model discloses a short-range kinetic energy expansion type disablement riot bullet head which has good shooting accuracy and stability, can form a wider impact area on a soft target, makes the target quickly disabled, and reduces the risk of excessive penetration.

[0006] The utility model discloses a short-range kinetic energy expansion type disablement riot bullet head which has good shooting accuracy and stability, can form a wider impact area on a soft target, makes the target quickly disabled, and reduces the risk of excessive penetration.

[0007] Optionally, the bullet core diameter is 5-13mm, the bullet core length is 9-11mm, the disablement pit depth is 3.5-4.5mm, the disablement pit maximum diameter is 2-7mm, the protective shell thickness is 0.3-0.8mm, and the pre-cracking disablement muscle diameter is 0.4-0.8mm.

[0008] Optionally, the protective shell inner wall is provided with 6 pre-cracking disablement muscles along the circumferential direction.

[0009] The utility model discloses a short-range kinetic energy expansion type disablement riot bullet head which has good shooting accuracy and stability, can form a wider impact area on a soft target, makes the target quickly disabled, and reduces the risk of excessive penetration.

[0010] The principle of the utility model: the elastic core adopts the lead-antimony alloy with 10-13% antimony which has been disclosed, as the limited material of the elastic core, because it is the existing material, and the material itself is not protected, and it does not involve the prior rights, the lead-antimony alloy with the proportion has better hardness and toughness, can satisfy the demand of the warhead expansion, in addition, the elastic core made of metal makes the warhead have stable flight trajectory;

[0011] The outer layer of the elastic core is provided with brass shell, first, the shape and structural integrity of the warhead are kept, and the shooting accuracy is provided; second, the internal elastic core is protected, and the elastic core is prevented from being damaged in the process of launching and flying, and the subsequent expansion of the warhead is affected; third, the energy loss of the warhead in the process of flying is reduced, and the warhead still has enough kinetic energy when hitting the target;

[0012] When shooting in the range of 20-30m from the soft target, the warhead will be subjected to the reverse force from the target after contacting the soft target, and the reverse force is small to large in the instant of acting on the warhead, due to the structure of the horn-shaped loss-of-function groove, the elastic core absorbs the gradually increasing reverse force from top to bottom, and the traces of the elastic core embedded along the pre-fracture loss-of-function rib are broken into several petals, the expanded elastic core drives the shell to tear along the pre-fracture loss-of-function rib into several petals, because most of the reverse force is absorbed by the elastic core, the force received by the shell is not very large, in addition, because the pre-fracture loss-of-function rib serves as a framework, the shell can be completely torn, so that the warhead does not produce fragments after hitting the human body, and expands into a complete flat flower shape in a very short time, forms a surface contact state, makes the soft target form a larger impact area, reduces the risk of excessive penetration, and makes the soft target produce greater pain in a short time, so that the soft target quickly loses the ability to resist;

[0013] When shooting at other distances from the soft target in the range of 20-30m, the distance from the soft target is too close, the energy is too large, the warhead does not have time to expand, and the risk of penetration is large; the distance from the soft target is too far, the energy is not enough, the warhead cannot effectively expand, and the purpose of making the soft target lose function cannot be achieved.

[0014] Compared with the prior art, the utility model has at least the following beneficial effects: the shooting accuracy and stability of the utility model are good, a wider impact area can be formed on the soft target, the target loses function quickly, and the risk of excessive penetration is reduced.
