Description

Technical Field

[0001] The invention relates to the technical field of riot control ammunition, in particular to a multifunctional gradient energy dissipation type rifled non-lethal kinetic energy bullet. Background Art

[0002] As the main component of modern riot control equipment, non-lethal kinetic ammunition plays an important role in controlling mass incidents and reducing casualties. However, existing non-lethal ammunition generally has problems such as single function, insufficient effectiveness and safety hazards. Traditional kinetic bullets mostly rely on a single impact, and the impact effect is concentrated in a local area, making it difficult to achieve large-scale dispersal or marking; chemical irritant release ammunition is limited by diffusion efficiency, easily affected by the environment, and lacks the ability to immediately control kinetic strikes. In addition, some ammunition uses hard materials or rigid structures, which poses a risk of accidental injury during high-speed collisions, making it difficult to meet safety requirements in complex scenarios.

[0003] In current technology, although there are attempts to combine kinetic energy and chemical agents with multifunctional designs, most of them adopt simple layered filling structures, which have problems such as insufficient release of agents and chaotic action sequence. For example, chemical powders often cannot be effectively diffused due to insufficient impact energy, or the deformation of the projectile is uncontrollable, resulting in secondary damage. At the same time, the gas-driven mechanism of existing ammunition mostly relies on gunpowder gas, which has defects such as unadjustable pressure and limited range of action, making it difficult to achieve synergistic enhancement of kinetic energy and chemical efficiency.

[0004] The above technical shortcomings restrict the comprehensive performance and application scenarios of non-lethal ammunition. Therefore, an innovative solution that integrates gradient energy consumption, multi-function integration and safety structure design is urgently needed to break through the existing technical bottleneck and meet the needs of efficient, accurate and safe riot control.

[0009] Preferably, high-pressure nitrogen is stored in the high-pressure gas cylinder, and the storage pressure of the high-pressure nitrogen in the high-pressure gas cylinder is 2.5 MPa.

[0010] Preferably, after the first-layer warhead hits a living target, the first-layer warhead, the second-layer warhead and the third-layer warhead are axially compressed, the OC stimulation powder ball and the fluorescent dye powder ball are ruptured under pressure, the warhead membrane is shattered, the first-layer warhead curling cavity, the second-layer warhead curling cavity and the third-layer warhead curling cavity are unfolded, and the OC stimulation powder and the fluorescent dye powder in the OC stimulation powder ball and the fluorescent dye powder ball are quickly sprayed near the strike target, and under the action of the axial compression force of the first-layer warhead, the second-layer warhead and the third-layer warhead, the needle tip of the three-layer warhead firing pin body shatters the sealing cover of the high-pressure gas cylinder, and the high-pressure nitrogen stored in the high-pressure gas cylinder is released at a high speed, realizing a secondary push on the first-layer warhead, the second-layer warhead and the third-layer warhead, and a wide spread of the OC stimulation powder and the fluorescent dye powder, thereby successively realizing multiple non-lethal effects such as a primary kinetic energy point strike, a secondary kinetic energy surface strike, stimulation dispersal and dyeing marking on the living target.

[0011] Preferably, the projectile assembly adopts a reversible deformation design, which can not only withstand the launch pressure but also avoid the risk of accidental injury to living targets caused by hard components. The hollow cavity in the lower projectile body is used to reduce the total weight of the projectile assembly.

[0012] Compared with the prior art, the present invention has the following advantages: (1) The present invention adopts a gradient energy dissipation warhead structure and material layering design. The warhead assembly adopts a stacked structure of three-layer mushroom-shaped warheads. Its core innovation lies in the synergistic effect of material density gradient and structural deformation. The three-layer warhead is made of polycarbonate foam, but the density decreases layer by layer (the first layer is the highest and the third layer is the lowest). This design allows the warhead to deform in stages when it hits the target: the high-density first-layer warhead is compressed first to absorb the impact energy, the medium-density second-layer warhead further dissipates kinetic energy, and the low-density three-layer warhead expands the contact area through greater deformation. The mushroom-shaped head of each layer of the warhead is combined with a curling cavity. When impacted, the curling cavity unfolds to release OC stimulating powder and fluorescent dye powder. This structure uses the dual energy dissipation mechanism of gradient material crushing and cavity expansion to reduce the penetration damage to the target and realize the timing control of kinetic strike and chemical agent release, solving the problem of single impact or insufficient agent release of traditional non-lethal ammunition; (2) The present invention innovatively uses the high-pressure gas synergistic drive and secondary energy release mechanism. A high-pressure gas cylinder and a firing pin body are arranged at the end of the three-layer warhead, which constitute the core innovation of the secondary energy release. When the warhead hits the target, the axial compression force of the three-layer warhead pushes the firing pin body forward, and its needle tip accurately pierces the fragile sealing cover of the high-pressure gas cylinder with a reserved gap of 7 mm. The 2.5MPa high-pressure nitrogen stored in the gas cylinder is released instantly, producing two effects: one is to promote the secondary impact of the deployed warhead assembly, and the three warheads achieve kinetic energy surface strikes; the second is that the high-speed airflow entrains the OC stimulating powder and the fluorescent dyeing powder to form a large-scale diffusion. This design breaks through the limitations of traditional ammunition that relies on gunpowder gas or passive diffusion, and realizes the dynamic coordination of energy and chemical efficiency through active gas drive, which significantly improves the efficiency of dispersal and marking; (3) The present invention adopts layered filling and particle size differentiated agent release technology. OC stimulating powder balls and fluorescent dyeing powder balls are filled in the curling cavity of the bullet in layers. The innovation lies in the packaging design with differentiated particle sizes and the optimization of spatial distribution. OC powder balls are filled in the first and third layer curling cavities, and the fluorescent powder balls are concentrated in the second layer curling cavities. The particle sizes of the powder balls in each layer are different (such as the outer layer powder balls are smaller for rapid rupture, and the inner layer powder balls are larger for delayed release). During impact, the bullet is compressed layer by layer, causing different cavities to rupture in turn. The OC stimulating powder is released first to form an immediate dispersal effect, and the fluorescent dyeing powder then diffuses to achieve target marking. In addition, the powder balls are wrapped with fragile materials to ensure uniform fragmentation after compression, avoiding the problem of uneven release caused by agent agglomeration in traditional ammunition. This layered timing control and particle size matching design achieves multi-stage precise release of chemical efficacy; (4) The projectile of the present invention adopts a reversible deformation and modular safety structure. The projectile assembly adopts low-density polyethylene material and hollow cavity design, which innovatively balances structural strength and safety flexibility. The upper projectile is locked with the projectile assembly through a heat-shrinkable warhead membrane, and the lower projectile is mechanically plugged into the shell to form a modular assembly structure. During launch, the elastic properties of low-density polyethylene cause the projectile to undergo reversible deformation when hitting the target, avoiding accidental penetration injuries caused by hard materials. At the same time, the interlocking design between the shell and the projectile is combined with hot melt adhesive sealing to ensure airtightness during launch. This structure takes into account both launch stability and impact safety, and solves the technical contradiction that traditional projectiles are strong in rigidity and easy to cause injuries; (5) The present invention uses a low-friction bullet membrane to optimize the compatibility with the rifling. The bullet membrane is made of polytetrafluoroethylene material with a friction coefficient of less than 0.3, which innovatively solves the compatibility problem between the rifled launch tube and the bullet. Traditional non-lethal bullets are prone to trajectory deviation or insufficient rotation speed under the action of the rifling due to the high friction coefficient of the bullet body material. The present invention wraps the three-layer bullet through the heat shrink process of the bullet membrane to form a smooth surface, reduce the friction resistance with the rifling, and use the toughness of the material to maintain the integrity of the bullet structure. During launch, the bullet membrane fits with the rifling to produce a stable spin, improving ballistic accuracy; during impact, the membrane body breaks and the bullet is deployed synchronously to avoid the film material residue affecting the release of chemical agents. This design combines low-friction packaging with functional release timing for the first time, achieving efficient compatibility between rifled weapons and non-lethal ammunition.
