Description

Technical Field

[0001] The present invention relates to the technical field of riot ammunition, and specifically to a non-lethal kinetic energy projectile with a decelerating type of payload spraying by separating the warhead. Background Art

[0002] Non-lethal kinetic energy projectiles need to achieve a delicate balance between effectively stopping the target's behavior and ensuring human safety. However, the existing technologies generally face the contradictory problem of muzzle velocity control. Traditional kinetic energy projectiles often adopt a low muzzle velocity design (such as 60 - 80 m / s) to reduce the risk of injury. However, too low a muzzle velocity results in insufficient momentum of the projectile body, making it difficult to drive the weapon's recoil system to complete an automatic cycle.

[0003] Another extreme in current technology is the design of kinetic energy projectiles with too high a muzzle velocity (120 - 150 m / s). Although it can improve the shooting accuracy and weapon reliability, the peak kinetic energy breaks through the safety threshold, which may lead to a sharp increase in the risk of secondary injuries such as skin penetration and rib fractures to the struck target. More seriously, the kinetic energy attenuation of the high-speed projectile body after rebounding from a hard surface (such as a wall) is limited, and the rate of stray bullet injury is more than 3 times higher than that of traditional designs. Although such designs meet the mechanical performance requirements of the weapon, they sacrifice safety and violate the core principle of non-lethal equipment.

[0004] Existing improvement schemes attempt to adjust the correlation between the muzzle velocity and kinetic energy through the projectile body structure (such as a hollow design) or materials (such as low-density polymers), but there are still significant limitations. Such technologies have not broken through the "triangle contradiction" of muzzle velocity - kinetic energy - recoil force, and can neither ensure the reliable operation of the weapon nor achieve the unity of human safety and tactical effectiveness. Therefore, there is an urgent need for an innovative design that breaks through the bottleneck of existing technologies and realizes the dynamic balance of muzzle velocity, recoil, and kinetic energy through the collaborative optimization of materials, structures, and timing control. Summary of the Invention

The upper projectile receiving cavity is clamped with a push plate. The outer diameter of the upper projectile receiving cavity is equal to that of the inner cavity of the load cylinder. The upper-side receiving ring of the upper projectile abuts against the lower end face of the side wall of the load cylinder. The lower-side receiving ring of the upper projectile abuts against the lower end face of the lower receiving ring of the load cylinder. A projectile band is provided at the connection part between the upper projectile and the lower projectile. The projectile band is a protruding cylindrical structure. The lower projectile includes a lower-projectile concave ring, an inner cavity of the lower projectile, a lower concave cavity of the lower projectile, and a delay tube socket. The lower-projectile concave ring is a circular ring with a semi-circular cross-section. Both the inner cavity of the lower projectile and the delay tube socket are cylindrical cavities. The delay tube socket penetrates through the upper projectile receiving cavity and the lower concave cavity of the lower projectile. A delay ignition tube is clamped inside the delay tube socket. The contact surface between the delay ignition tube and the delay tube socket is sealed with 814 glue; The lower side of the projectile component is mechanically plugged with a launch component. The launch component includes a cartridge element and a charge. The cartridge element is used to connect and support the lower projectile. The cartridge element includes a cartridge case, a cartridge case convex ring, a cartridge case bottom edge, a primer hole, a high-pressure chamber, a flash hole, and a low-pressure chamber. The upper end face of the cartridge case abuts against the lower side of the projectile band. An inner side of the upper part of the cartridge case is provided with a cartridge case convex ring with a semi-circular cross-section. The cartridge case convex ring is squeezed into the lower-projectile concave ring. The side wall of the lower projectile abuts against the inner wall of the cartridge case.

The propellant is bulk smokeless powder. The cavity formed by the inner side of the cartridge case, the outer side of the high-pressure chamber, and the lower concave cavity of the lower projectile is the low-pressure chamber.

[0007] Preferably, the warhead component, the load component, the projectile component, and the launch component are all axisymmetric structures, and the central axes of the warhead component, the load component, the projectile component, and the launch component coincide.

[0008] Preferably, the warhead frustum, the blasting frustum, and the solid expanding explosive are all frustum-shaped with similar structures, which can realize the directional release of the blasting pressure and improve the directional soft strike accuracy of the warhead component.

[0009] Preferably, the delay time of the delay ignition tube is 3S.

[0010] Preferably, 814 glue is used for adhesive fixation between the contact surfaces of the upper bearing ring of the load cylinder and the upper expanding explosive body bearing ring, and between the upper projectile body and the load cylinder.

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

[0012] Preferably, after the primer is struck and ignited by the anti-riot firing pin, the propellant is ignited. The propellant burns violently to generate a large amount of gunpowder gas, which breaks through the brass film sealing the fire transfer hole. The gunpowder gas enters the low-pressure chamber to ablate the hot melt adhesive sealing the projectile assembly and the launch assembly, pushing the projectile assembly to separate from the launch assembly. The gunpowder gas ignites the delay ignition tube. The warhead assembly, load assembly, and projectile assembly fly out of the barrel under the action of the gunpowder gas. After a 3S delay, the tail of the delay ignition tube ignites the bulk black powder in the axial fire transfer tube. The flame ablates the hot melt adhesive sealing the radial fire transfer tube, and the flame preferentially ignites the bulk expanding explosive in the lower expanding explosive body. The bulk expanding explosive burns violently, pushing the push plate forward. The solid expanding explosive is then ignited, causing a violent explosion, pushing the warhead assembly to separate from the load assembly, achieving a precise kinetic energy soft strike on the expected target. The blasting ring and blasting frustum are shattered. The OC stimulating powder loaded in the load cavity is dispersed and stimulated to the target under the high-speed pushing action of the push plate. The backward movement of the projectile assembly caused by the interaction between the forward spraying of the OC stimulating powder and the explosion impact force together achieves the deceleration purpose and can reduce the probability of accidental injury.

[0013] The present invention has the following advantages compared with the prior art: (1) The warhead assembly of the present invention adopts a collaborative design of a stepped structure and a high-ductility material. The warhead assembly is integrally vacuum-coated and formed by a high-ductility polyurethane material, combined with the geometric innovation of the spherical head body, stepped cylinder, and warhead frustum, to achieve a balance between kinetic energy transfer and safety. The hemispherical design of the spherical head body can disperse the impact pressure. The stepped cylinder forms a warhead bearing ring through the gradual reduction of the outer diameter, combined with the micron-level grooves engraved on the surface by laser, to enhance the energy absorption capacity of the warhead deformation. When hitting the target, the ductility of the polyurethane material causes the warhead to undergo controllable plastic deformation, significantly reducing the kinetic energy density per unit area and avoiding local penetration injuries caused by hard materials. At the same time, the geometric matching design of the warhead frustum and the blasting frustum ensures the directional release of the explosion pressure and improves the soft strike accuracy; (2) The present invention innovatively designs a double-layer explosion sequence driving mechanism for the payload assembly. The payload assembly adopts a double-layer sequential combustion design of solid explosive and bulk explosive, and realizes the coordination of dispersal and deceleration functions through the graded ignition logic of the axial fire transfer tube and the radial fire transfer tube. The bulk explosive in the lower explosive body is ignited first, pushing the push plate forward at high speed, squeezing the OC stimulation powder in the load chamber forward to gather; then the solid explosive is ignited, and the explosion shock wave is released directionally through the pressure relief hole of the explosion tube, prompting the warhead assembly to separate from the payload assembly, and at the same time realizing the rapid spreading of the OC stimulation powder. This layered explosion mechanism ensures the precise timing of the release of the dispersal powder and the ejection of the warhead. At the same time, the reverse effect of the explosion impact force and the powder spraying form a "thrust offset effect", forcing the end of the projectile assembly to slow down, effectively reducing the risk of secondary damage; (3) The projectile assembly of the present invention adopts reversible deformation materials and hollow lightweight structure design. The projectile assembly adopts low-density polyethylene material and lower projectile inner cavity design, and realizes the dual functions of launch pressure bearing and kinetic energy absorption through reversible deformation characteristics. The upper projectile is tightly clamped with the load tube through the receiving cavity to ensure the axial force transmission at the moment of launch; the cylindrical convex structure of the band cooperates with the convex ring of the shell to enhance the air-tightness in the chamber. The hot melt adhesive sealing design of the lower projectile concave ring and the convex ring of the shell can not only withstand the impact of high-pressure gas, but also can be quickly separated when the projectile flies away. The hollow cavity reduces the weight of the projectile and improves the initial velocity stability. At the same time, the deformation of the material can absorb part of the impact kinetic energy, avoiding accidental damage to the target caused by hard components. In addition, the 3S precise delay of the delayed ignition tube ensures the time and space matching of the expansion action and the end of the trajectory, improving tactical controllability.

[0014] (4) The launch assembly of the present invention adopts a high- and low-pressure chamber gas graded utilization system. The launch assembly optimizes the distribution of gunpowder gas energy through the graded design of the high-pressure chamber and the low-pressure chamber. After the primer ignites the propellant, the gas pressure in the high-pressure chamber rises instantly, breaking through the fire transfer hole sealed by the brass diaphragm, and the high-pressure gas enters the low-pressure chamber to push the projectile assembly out of the cartridge case. This design releases the gas energy in stages: the high-pressure chamber ensures the stability of the initial velocity of the projectile, and the low-pressure chamber buffers the recoil to a range that the weapon can withstand. At the same time, the low-pressure chamber gas triggers the separation of the projectile by ablating the hot melt adhesive, and ignites the delayed ignition tube, realizing the timing control of the entire process of launch, separation, and explosion expansion. This structure breaks through the energy waste problem of the traditional single-chamber design, increases the gas utilization rate by 50%, and takes into account the dynamic balance between initial velocity and safety.

[0015] (5) The axisymmetric integrated structure of the present invention effectively improves the flight stability of the projectile. The entire projectile adopts an axisymmetric design, and the central axes of the warhead assembly, payload assembly, projectile body assembly, and launch assembly strictly coincide. Combining the precise matching of the bearing rings of each component (such as the upper booster body bearing ring and the upper bearing ring of the payload cylinder), the eccentric moment is eliminated. The similar frustum geometric configurations of the warhead frustum, blasting frustum, and solid booster charge ensure that the explosion pressure is evenly released along the axis, reducing the lateral energy dissipation. In addition, the polytetrafluoroethylene material of the payload cylinder has both a low friction coefficient and high temperature resistance characteristics, reducing the air resistance and thermal deformation interference during ballistic flight. The axisymmetric structure improves the gyroscopic stability of the projectile body, significantly improving the hitting accuracy of moving targets. At the same time, it avoids the irregular release of kinetic energy caused by the tumbling of the projectile body, further reducing the injury risk. BRIEF DESCRIPTION OF THE DRAWINGS

[0026] In this embodiment, the delay time of the delay ignition tube 3-4 is 3S.

[0027] In this embodiment, the contact surface between the upper bearing ring 2-2-1 of the load cylinder and the upper explosion-expanding body bearing ring 2-1-6, and the contact surface between the upper projectile body 3-1 and the load cylinder 2-2 are adhesively fixed with 814 glue.

[0028] In this embodiment, the projectile assembly 3 is designed with reversible deformation, which can not only withstand the launch pressure but also avoid the risk of accidental injury to living targets caused by hard components. The inner cavity 3-3-2 of the lower projectile body is used to reduce the total weight of the projectile assembly 3.

[0029] In this embodiment, after the primer 4-2-1 is struck and ignited by the anti-riot firing pin, the propellant 4-2-2 is ignited. The propellant 4-2-2 burns violently to generate a large amount of gunpowder gas, which breaks through the brass film of the sealed fire-transfer hole 4-1-6. The gunpowder gas enters the low-pressure chamber 4-1-7 to ablate the hot-melt adhesive between the sealed projectile assembly 3 and the launch assembly 4, and pushes the projectile assembly 3 and the launch assembly 4 to separate. The gunpowder gas ignites the delay ignition tube 3-4. The warhead assembly 1, the load assembly 2 and the projectile assembly 3 fly away from the barrel under the action of the gunpowder gas. After a 3S delay, the tail of the delay ignition tube 3-4 ignites the bulk black powder in the axial fire-transfer tube 2-3. The flame ablates the hot-melt adhesive sealing the radial fire-transfer tube 2-4, and the flame preferentially ignites the bulk explosion-expanding charge in the lower explosion-expanding body 2-7. The bulk explosion-expanding charge burns violently, pushing the push plate 2-6 forward. The solid explosion-expanding charge 2-1-5 is then ignited, causing a violent explosion, which pushes the warhead assembly 1 to separate from the load assembly 2, achieving a precise kinetic energy soft strike on the intended target. The blasting ring 2-1-1 and the blasting frustum 2-1-2 are shattered. The OC stimulating powder filled in the load chamber 2-5 is stimulated and dispersed to the target under the high-speed push of the push plate 2-6. The backward movement of the projectile assembly 3 caused by the interaction between the forward spraying of the OC stimulating powder and the explosion impact force together achieves the deceleration purpose, which can reduce the probability of accidental injury.

[0030] Although the embodiments of the present invention have been shown and described, those of ordinary skill in the art can understand that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principles and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
