Description

Technical Field

[0001] The present invention relates to the technical field of non-lethal ammunition, in particular to an airbag ejection type non-lethal kinetic energy bullet with stable impact. Background Art

[0002] The development of non-lethal kinetic energy bullets is not about replacement and elimination, but about "going hand in hand and using as needed". Different types of bullets can be selected for different usage environments. Although there are various types of bullets, the main goal is to achieve the purpose of dispersing and denying the target by causing temporary pain to the target.

[0003] The current development direction of new non-lethal kinetic bullets is composite projectiles, and the main goal is to solve the problems of unstable power and insufficient precision of current ammunition to improve the versatility of projectiles. An analysis of current domestic patents related to non-lethal kinetic bullets found that the main solution is to change the warhead material, improve the warhead structure, add energy dissipation devices, add tail devices, and add acceleration devices. The change of warhead materials from hard projectiles to soft projectiles can effectively reduce excessive damage to the target. Patent CN102155884A uses a bullet support and soft projectile assembly made of low-density polyethylene material to ensure that when the projectile hits the target at different distances, the impact area will automatically adjust to reduce excessive damage to the target. This design is suitable for riot control sites, effectively controlling the crowd and reducing the risk of casualties. The improvement of the warhead structure helps to increase the accuracy of the strike and the flexibility of the use scenario. Patent CN113899253A designs a composite non-lethal kinetic bullet, which uses an over-caliber honeycomb warhead and has multiple non-lethal effects such as blast deterrence, tear gas dispersal, kinetic strikes and dyeing markings. The bullet assembly expands radially after flying off the barrel, achieving an over-caliber effect and improving the accuracy of the strike. Patent CN115540698A designs an impact-buffered non-lethal kinetic bullet with an extended inner core. The built-in buffer air cushion and ductile inner core effectively reduce excessive damage to the organism. The bullet wall breaks along the crack when impacted, releasing the inner core to achieve multi-point soft strikes, improving safety and effectiveness. In order to ensure the range of non-lethal kinetic bullets while not causing excessive damage due to excessive power, many researchers use energy dissipation devices to reduce the power. Patent CN115127405A designs an explosive deceleration composite kinetic bullet with a built-in range-finding fuze. Through the range-finding fuze in the soft bullet body, the rapid-burning charge is detonated at a predetermined distance to achieve bullet body pressure relief and OC stimulation powder spraying, reducing the probability of close-range injuries. Patent CN114923374A introduces a composite non-lethal kinetic projectile with a progressive deceleration characteristic. Through a multi-level buffer structure and a progressive deceleration design, it ensures that when the projectile hits the target at different distances, the energy is gradually dissipated, reducing excessive damage to the target. In order to increase the range of non-lethal kinetic projectiles and improve accuracy at the same time, many projectiles adopt the method of adding tail devices. Patent CN113720212A introduces a multi-effect composite kinetic projectile with a telescopic tail stabilized by a projectile body. Through a flame delay tube and an expansion cartridge, the inner projectile body is pushed to slide downward, the projectile body is elongated and the tail is extended to ensure the smooth flight of the projectile. Patent CN112945024A proposes a composite kinetic projectile with coupled spin stabilization and resistance stabilization, using a front warhead, a middle warhead and a rear warhead design that are fixed by front and rear adhesives, and a belt and an inclined tail are designed on the rear warhead, combining spin and resistance stabilization to improve the strike accuracy and initial velocity consistency. The range can also be increased by adding an acceleration device.Patent CN113607007A introduces a sensor-controlled secondary acceleration composite kinetic energy projectile, which detects the flight distance of the projectile through a built-in sensor, controls the start of the secondary propulsion device, and realizes the secondary acceleration of the projectile. Patent CN113587736A proposes a composite kinetic energy projectile with a delayed boost function, which realizes delayed boost of the projectile during flight through a built-in delay tube and explosive, thereby increasing the initial velocity and effective range of the projectile.

[0004] At present, non-lethal kinetic bullets still have problems of uncertain power and insufficient accuracy, which has continuously caused a series of excessive injury incidents, resulting in many injuries and even deaths. For humanitarian and international public opinion considerations, international peacekeeping organizations also temporarily suspended the use of rubber bullets. In order to solve these two problems, the current methods include variable initial velocity technology, changing structure, replacing materials and speed control. Among them, variable initial velocity technology mainly changes the initial velocity of the projectile by changing the design of the gun to achieve power changes, with complex structure and poor versatility. The current method of changing the structure is mainly to change the shape of the projectile body, adjust the power by the contact area and contact mode, and cannot keep the power constant. Replacing materials means replacing with some softer and more deformable materials, sacrificing the use effect. Speed ​​control refers to the design ideas of rockets. Although the range is increased, the effective range is also narrower, and the power is easily too large or too small. Therefore, the current solution is often just to expand the scope of use or compromise on power, and cannot fundamentally solve the problem of matching excessive injury and use effect. Summary of the invention

In the present invention, the accelerometer serves as a switch (or insurance mechanism) of the pulse laser ranging module. When the acceleration of the airbag pop-up non-lethal kinetic energy bullet with stable impact reaches a certain threshold, it is assumed that the airbag pop-up non-lethal kinetic energy bullet with stable impact is fired, and the pulse laser ranging module starts to work.

[0029] Specifically, Figure 1 and Figure 2As shown, the upper shell 100 includes an outer shell 101 and an inner shell. The front end of the outer shell 101 is provided with a transparent window 115. The outer shell 101 is provided with more than or equal to two through grooves 117 with openings facing outward along the circumference of the outer shell 101. The thickness of the outer shell 101 between the bottom of the through groove 117 and the inner wall of the outer shell 101 is 0.2 to 0.3 mm, preferably 0.25 mm; the inner shell includes an upper shell 102, a middle shell 103 and a lower shell 104 which are fixedly connected in sequence. The upper shell 102 and the middle shell 103 are connected to each other. A first partition 116 is provided between the middle shell 103 and the lower shell 104, a second partition is provided between the middle shell 103 and the lower shell 104, and a one-way air-blocking mechanism 114 is provided on the second partition; a pulse laser ranging module 107 is arranged at the top of the upper shell 102, a control module 108 is arranged in the middle section of the upper shell 102, a power supply 110 and an electric ignition device 109 are respectively arranged in the lower section of the upper shell 102, and an ignition head of the electric ignition device 109 is arranged in the middle shell 103, and an ignition powder 111 is arranged in the middle shell 103. The gas generating agent 112 is arranged in the lower shell 104; the airbag 106 is arranged in the cavity between the outer shell 101 and the inner shell in a plane folding, a roll folding, a circumferential tightening folding or an absorption folding manner, and the airbag 106 and the lower shell 104 are fluidly connected through the air guide hole 105 arranged on the shell wall of the lower shell 104; after the electric ignition device 109 ignites the ignition powder 111, the ignition powder 111 in the burning state forms a hot spot, and the gas generating agent 112 is ignited through the one-way air-closing mechanism 114, and the gas in the burning state is The gas generated by the generator 112 enters the airbag 106 through the air guide hole 105 and fills the airbag 106. The filled airbag 106 is squeezed to cause the outer shell 101 to rupture along the through groove 117 and then pops out from the cavity between the outer shell 101 and the inner shell. The air guide hole 105 is a conical hole and the end adjacent to the gas generator 112 is a contracted end. In order to prevent solid residues generated by the gas generator 112 from entering the air guide hole 105 and blocking the air guide hole 105, a filter 113 is provided on the inner wall of the lower shell 104.

[0030] In the present invention, the material of the transparent window 115 is transparent acrylic, and the material of the outer shell 101 is PP5 or HDPE2.

[0031] In order to ensure the flight stability of the airbag pop-up non-lethal kinetic energy projectile with stable impact, in this embodiment, a middle projectile body 300 with a flight stabilization system is added at the tail, and the upper projectile body 100 and the lower projectile body 200 are detachably connected through the middle projectile body 300; after the airbag pop-up non-lethal kinetic energy projectile with stable impact is ejected, the middle projectile body 300 is separated from the lower projectile body 200; when the middle projectile body 300 and the lower projectile body 200 are not separated, the lower section of the flight stabilization system is set in the cavity between the top of the lower projectile body 200 and the middle projectile body 300, such as Figure 2As shown; after the middle projectile body 300 is separated from the lower projectile body 200, one end of the flight stabilization system is placed outside the middle projectile body 300. The flight stabilization system includes a folding tail mechanism 400. After the middle projectile body 300 is separated from the lower projectile body 200, the folding tail mechanism 400 automatically opens under the action of inertia and one end of the folding tail mechanism 400 is located outside the middle projectile body 300 to increase the range and improve the accuracy.

[0032] To prevent the burning products generated after the propellant 203 is ignited from damaging the folding tail mechanism 400, in this embodiment, a sabot 204 is provided in the lower projectile body 200, and the lower section of the flight stabilization system is provided in the cavity between the sabot 204 and the middle projectile body 300.

[0033] In the present invention, the launch system is responsible for launching the projectile, which meets the design specifications of 38mm ammunition; the airbag 106 system is the source of the wounding power, and the target power is not to cause penetration or penetration type damage; the fuze system controls the ejection time of the airbag 106, and the airbag 106 is ejected at a distance of 100 to 150 cm from the target. When the airbag 106 is ejected, a pressure is generated in all directions. The backward pressure can be used to offset the kinetic energy of the airbag ejection type non-lethal kinetic energy bullet with stable impact, and the forward pressure can enable the airbag 106 to exert the required impact force on the target receptor, that is, to ensure that the power of the airbag ejection type non-lethal kinetic energy bullet with stable impact on the target receptor is constant. When shooting, the ammunition is loaded with back-fire, filled into the grenade launcher, and fired after aiming at the target. The firing pin fires the primer 202, ignites the propellant 203, and ejects the airbag pop-up non-lethal kinetic energy ejection with stable impact. At the same time, the gas generated by the propellant 203 enters the cavity between the cartridge case 204 and the bottom of the lower projectile shell through the fire transfer hole 205, forming high pressure, so that the lower projectile shell and the middle projectile 300 are separated, and the lower projectile 200 is thrown away. After the airbag pop-up non-lethal kinetic energy ejection with stable impact is ejected, the folding tail mechanism 400 is unfolded to ensure flight stability. Affected by the launch inertia, the safety is released, the power supply 110 is powered, and the pulse laser ranging module 107 continues to work. When it detects that the distance to the target receptor is 100 to 150 cm, the ignition signal is transmitted to the electric ignition device 109, and the electric ignition device 109 ignites the ignition powder 111, which further ignites the gas generator 112. The burning gas generator 112 produces a large amount of gas within 30 ms and fills the airbag 106. The filled airbag 106 breaks through the outer shell 101 and generates a thrust backward to offset the impact kinetic energy of the airbag pop-up non-lethal kinetic energy bullet with stable impact, and at the same time generates a thrust forward, and then the filled airbag 106 hits the target.

[0034] Specifically, the primer 202 and the propellant 203 used in the launch system of the present invention are the same as those of the 38mm kinetic bullet. The gas generator 112, the electric ignition device 109 and the lower shell 104 are constructed into a gas generator, and the timing of starting the gas generator is controlled by the fuze system to ensure that the gas generator is started at the right time. The current gas generator 112 is mainly composed of a gas-producing fuel with a high nitrogen content and a common oxidant, and some additives are added according to the difference in the working environment. The gas generator 112 is usually divided according to the type of gas-producing fuel, and then its performance is adjusted by adding different oxidants. The common components of the gas generator 112 are shown in Table 1.

[0035] Table 1 Common gas generating agent 112 components

[0036]

[0037]

[0038] The gas generator 112 used in the present invention is a guanidine nitrate-based gas generator, which is composed of guanidine nitrate, basic copper carbonate, ammonium perchlorate and potassium nitrate in a mass ratio of 55:24:10:10. The gas generator 112 composed of this formula has a combustion speed of 0.867 mm / s, an explosion temperature of 1901K, a gas production of 0.67 L / g, and an amount of the gas generator 112 is 1.25 to 3.5 g.

[0039] The airbag 106 is made of the same material as the current main driver's airbag 106 of the automobile, and is woven with nylon 6.6 as the airbag cloth, with a thickness of 0.35mm±0.05mm. The mainstream folding methods of the airbag 106 include plane folding, roll folding, circumferential tightening folding and absorption folding.

[0040] Since the triggering time of the gas generator 112 needs to be controlled more accurately, the pulse laser ranging module 107 is used in the present invention to measure the distance between the flying upper projectile 100 and the target receptor. The pulse laser ranging module 107 irradiates the target with a specific laser beam through an optical transmitting system, and receives the diffusely reflected laser echo of the target with an optical receiving system, and processes the received optical signal. When the fuze recognizes the target and is within the optimal explosion point position range, a detonation signal is generated through the control module 108, and the electric ignition device 109 is started for ignition. Among them, the pulse laser ranging usually uses a high-speed counter to measure the return time of the laser pulse. Under the action of the driving signal, the laser is controlled to emit a pulse laser, and a signal is fed back to the signal processing part as the timing start time. The laser pulse irradiates the target through the transmitting optical system. The laser echo pulse signal reflected from the target is converted into an electrical signal by the photoelectric detector, and is amplified and shaped as the counter timing end time. The counting result multiplied by the counting cycle is the round trip time of the laser pulse.

[0041] The distance measurement principle of the pulse laser ranging module 107: Assuming that the round trip time of the laser pulse from the ranging point to the target is t, the distance R of the measured target is:

[0042]

[0043] Where c is the speed of light in air, ignoring the atmospheric effect c = 2.9971×10 8 m / s.

[0044] When the pulse laser ranging module 107 is used to measure the distance between the upper projectile 100 and the target receptor and the control module 108 is used to generate a detonation signal, the speed and total duration of gas generation of the gas generating agent 112 and the flight speed and attenuation of the speed of the airbag pop-up type non-lethal kinetic energy projectile with stable impact are taken into consideration, and the impact of the airbag pop-up type non-lethal kinetic energy projectile with stable impact on the target receptor is also taken into consideration. In the present invention, when the pulse laser ranging module 107 measures that the distance between the upper projectile 100 and the target receptor is 100-150cm, the control module 108 generates a detonation signal. In this case, it can be ensured that the outer shell 101 will not hit the target receptor, and at the same time, it can be ensured that the airbag 106 can give the target receptor a non-lethal impact when it hits the target receptor after squeezing through the outer shell 101. At this time, the striking force of the airbag pop-up type non-lethal kinetic energy projectile with stable impact on the target receptor mainly comes from the impact force formed when the airbag 106 is ejected from the outer shell 101.

[0045] When the present invention is used to shoot at the target receptor, the part of the airbag pop-up non-lethal kinetic energy bullet with stable impact that contacts the target receptor is the airbag 106 popped out from the upper projectile body 100. Compared with conventional kinetic energy bullets, not only is the contact surface relatively large, but also it has good flexibility. Under the condition of being able to ensure effective impact on the target receptor, it will not cause fatal damage to the target receptor. The reason is that the high-speed moving airbag 106 has a large impact on the target receptor, causing the target receptor to be injured under the impact, but the contact surface between the airbag 106 and the target receptor is large, and the unit area pressure generated by the airbag 106 on the target receptor is small, which will not cause more serious destructive damage to the target receptor. At the same time, the airbag 106 is a flexible item, and the gas is compressible, so the impact of the airbag 106 on the target receptor will not be released in an instant, and it takes a certain amount of time to release the impact, which makes the impact of the airbag 106 on the target receptor maintain at a non-lethal power, ensuring the life safety of the target receptor.

[0046] Obviously, the above embodiments are merely examples for the purpose of clear explanation, and are not intended to limit the implementation methods. For those skilled in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation methods here. The obvious changes or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
