Description

Technical Field

[0001] The invention relates to the technical field of riot control ammunition, in particular to a rifled multifunctional ellipsoidal kinetic energy bullet. Background Art

[0002] Currently, as non-lethal law enforcement equipment, anti-riot ammunition needs to take into account safety, functional diversity and effectiveness when controlling violent conflicts. However, existing technologies still have the following limitations: The first is the single function defect. Traditional anti-riot ammunition focuses on a single function, such as kinetic strike or chemical irritant release, and it is difficult to simultaneously achieve complex requirements such as kinetic suppression, chemical dispersal and target marking in a single action. For example, ordinary rubber bullets only rely on kinetic pain to disperse, while tear gas bombs lack accurate marking capabilities, making subsequent tracking difficult.

[0003] Second, the structural reliability is insufficient. Some multifunctional ammunition adopts split design or complex mechanical structure, which is prone to structural failure due to stress concentration during high-speed firing or collision, affecting the stability of function release. In addition, unscientific load chamber separation may lead to mixing of different agents, reducing effectiveness.

[0004] The third is the limitation of material performance. Projectile materials often face the contradiction between strength and ductility. Although traditional hard materials can withstand chamber pressure, they are easy to break when impacted, affecting the release of secondary functions; while flexible materials can buffer impact, it is difficult to ensure ballistic stability and load sealing.

[0005] Fourth, the efficiency of load release is low. Existing ammunition relies on a simple rupture mechanism to release the agent, which has problems such as delayed release and uneven spraying. For example, some dyed bullets have unreasonable pore design, which limits the powder diffusion range and the marking effect is not significant.

[0006] In response to the above problems, there is an urgent need for a riot control ammunition that integrates kinetic strike, stimulation dispersal, and dyeing marking, and has both structural reliability, material adaptability and efficient release capability. Summary of the invention

[0009] Preferably, the upper ellipsoid, the lower ellipsoid, the projectile membrane and the shell element are all axisymmetric structures, and the central axes of the upper ellipsoid, the lower ellipsoid, the projectile membrane and the shell element coincide with each other.

[0010] Preferably, the semicircular structure of the upper ellipsoidal elastic band and the lower ellipsoidal elastic band can effectively avoid excessive abrasions to the skin of the living target.

[0011] Preferably, the primer is ignited by the impact of the firing pin to ignite the propellant, and the combustion of the propellant generates combustion gas that breaks through the brass diaphragm that seals the fire transfer hole. The combustion gas generated by the combustion of the propellant enters the low-pressure chamber from the fire transfer hole, ablates the hot melt adhesive that seals the lower ellipsoid and the shell element, and pushes the lower ellipsoid to separate from the shell element, and the projectile assembly enters the rifled launch tube, and the upper ellipsoid belt and the lower ellipsoid belt are squeezed into the rifling of the rifled launch tube in turn, pushing the projectile assembly to achieve overall spin, and the upper ellipsoid hits the target to achieve a kinetic energy strike on the target, and the projectile membrane ruptures due to stress, and under the action of inertia, the upper ellipsoid and the lower ellipsoid are continuously compressed, and the upper ellipsoid radial partition, the upper ellipsoid axial partition, the lower ellipsoid radial partition and the lower ellipsoid axial partition are crushed, forcing the OC stimulation powder and the fluorescent dyeing powder to be sprayed from the directional micro-pores at high speed, thereby achieving stimulation, dispersal and dyeing marking of the target.

[0012] Compared with the prior art, the present invention has the following advantages: (1) The present invention innovatively uses composite ellipsoid structure design and functional integration optimization. A composite structure of an upper ellipsoid and a lower ellipsoid cross-stacked is adopted, in which the upper ellipsoid is a vertical ellipsoid with its long axis along the axial direction, and the lower ellipsoid is a horizontal ellipsoid with its long axis along the radial direction, and the two are wrapped as a whole by heat shrinking the projectile film. This design optimizes the aerodynamic shape of the projectile through the geometric characteristics of the ellipsoid and reduces flight resistance; at the same time, the interiors of the upper and lower ellipsoids are divided into independent load chambers by cross-crossed upper ellipsoid radial partitions, upper ellipsoid axial partitions and corresponding lower ellipsoid partitions, which are respectively filled with OC stimulation powder and fluorescent dye powder, to achieve the synchronous functional integration of kinetic strike, chemical dispersal and dye marking. Compared with traditional split ammunition, this structure greatly improves the comprehensive effectiveness of single-shot ammunition through spatial reuse, while avoiding mechanical interference between functional modules; (2) The present invention achieves material synergy between the high-ductility skin layer and the nano-composite middle layer. The upper ellipsoid skin layer and the lower ellipsoid skin layer are made of high-ductility polyurethane material, and the surface is laser-engraved with micron-level grooves to enhance aerodynamic stability and surface friction adaptability. The upper ellipsoid middle layer and the lower ellipsoid middle layer wrapped in the skin layer are made of polyurethane foam material doped with silica nanoparticles, which significantly improves the strength-density ratio, ensuring the projectile's ability to resist chamber pressure and achieving high-speed load release through directional micro-pores. In the material combination, the ductility of the skin layer buffers impact stress, and the nano-reinforced structure of the middle layer supports the stability of the load cavity. The two work together to solve the problem of traditional projectiles being "hard and brittle" or "too soft and unstable"; (3) The present invention innovatively uses a highly efficient load release mechanism of fragile baffles and directional air holes. The cross-shaped upper ellipsoid radial baffles and axial baffles (and the corresponding parts of the lower ellipsoid) in the load chamber are made of fragile and brittle polycarbonate material. When the projectile hits the target, the inertial force compresses the ellipsoid structure, and the baffle is instantly broken by the shear stress, forcing the OC stimulating powder and the fluorescent dye powder to be ejected at high speed through the directional micro-pores. The pores are distributed in a spiral array along the surface of the projectile, and combined with the centrifugal force generated by the spin of the projectile, the agent can be evenly diffused in 360°. Compared with the traditional rupture release, this design reduces the release delay to the millisecond level through the linkage control of the preset pores and baffles, and the powder injection speed is increased by more than 30%, significantly enhancing the dispersal and marking effects; (4) The present invention adopts a dual-chamber gas drive and a cartridge case mechanical locking structure. In the firing assembly, the high-pressure chamber and the low-pressure chamber are connected through a fire transfer hole. After the propellant burns, the high-pressure gas breaks through the brass diaphragm and enters the low-pressure chamber, ablating the hot-melt adhesive sealing layer between the lower ellipsoid and the cartridge case element, pushing the projectile assembly out of contact. At the same time, the mechanical locking design of the cartridge case convex ring and the lower ellipsoid concave ring ensures accurate axial positioning of the projectile under chamber pressure, avoids structural dislocation at the moment of firing, and ensures a consistent pulling force. The dual-chamber drive system controls the gas release rate through a pressure gradient, which not only ensures the stability of the initial velocity of the projectile, but also reduces the impact of the peak chamber pressure on the projectile, thereby improving the safety of firing; (5) The present invention innovatively uses the dual-belt-rifle coupled spin control technology. The upper ellipsoidal belt and the lower ellipsoidal belt adopt a semicircular cross-section ring structure, which is respectively located on the outer wall of the short axis of the upper ellipsoid and the outer wall of the long axis of the lower ellipsoid. During firing, the two belts are sequentially embedded in the rifling of the rifled launch tube, and the rifling guide action forces the projectile assembly to spin at high speed. The staggered layout of the upper and lower belts forms a "double driving point", which enhances the uniformity of the spin torque and improves the ballistic stability. The gyroscopic effect generated by the spin not only improves the flight accuracy, but also pre-tightens the internal structure of the projectile through centrifugal force to prevent the partition from breaking prematurely, ensuring that the function release sequence is accurate and controllable.
