Description

Technical Field

[0001] This invention relates to the field of non-lethal ammunition technology. Specifically, it relates to a non-lethal kinetic energy projectile with a stable impact, which is delivered via a gasbag. Background Technology

[0002] The development of non-lethal kinetic energy rounds is not about replacement or elimination, but rather a process of "advancing together and using as needed." Different types of rounds can be selected for different usage environments. Although there are various types of rounds, the main goal is to dispel and deter targets by causing temporary pain.

[0003] The current development trend of new non-lethal kinetic energy munitions is towards composite projectiles, with the primary goal of addressing the issues of inconsistent power and insufficient accuracy in current ammunition, thereby improving projectile versatility. Analysis of current domestic patents related to non-lethal kinetic energy munitions reveals that the main solutions involve changing the projectile material, improving the projectile structure, adding energy dissipation devices, adding tail fins, and adding acceleration devices. The shift from hard projectiles to soft projectiles can effectively reduce excessive damage to targets. Patent CN102155884A uses a sabot and soft projectile assembly made of low-density polyethylene material to ensure that the impact area automatically adjusts when the projectile hits the target at different distances, reducing excessive damage. This design is suitable for riot control, effectively controlling crowds and reducing the risk of casualties. Improvements in the projectile structure contribute to increased accuracy and greater flexibility in application scenarios. Patent CN113899253A designs a composite non-lethal kinetic energy munition using an over-caliber honeycomb projectile, possessing multiple non-lethal effects such as blast deterrence, tear gas dispersal, kinetic energy strike, and color marking. The projectile assembly expands radially after leaving the barrel, achieving an over-caliber effect and improving accuracy. Patent CN115540698A designs an impact-buffered non-lethal kinetic energy projectile with an extended inner core. Through an internal buffer cushion and an extended inner core, it effectively reduces excessive damage to living organisms. The projectile wall fractures along a groove upon impact, releasing the inner core and achieving multi-point soft impact, improving safety and effectiveness. To ensure the range of non-lethal kinetic energy projectiles without causing excessive damage due to excessive power, many researchers use energy dissipation devices to reduce power. Patent CN115127405A designs a decelerating composite kinetic energy projectile with an internal rangefinder fuse. Through the rangefinder fuse within the soft projectile body, it detonates the fast-burning propellant at a predetermined distance, achieving projectile depressurization and OC-stimulating powder spray, reducing the probability of close-range injury. Patent CN114923374A introduces a composite non-lethal kinetic energy projectile with progressive deceleration characteristics. Through a multi-stage buffer structure and progressive deceleration design, it ensures that the energy is gradually dissipated when the projectile impacts the target at different distances, reducing excessive damage. To increase the range and improve accuracy of non-lethal kinetic energy projectiles, many projectiles incorporate tail fin devices. Patent CN113720212A introduces a telescopic tail fin-stabilized multi-effect composite kinetic energy projectile. Through a flame delay tube and a propulsion cartridge, the inner projectile body slides downwards, elongating the projectile body and extending the tail fins to ensure stable flight. Patent CN112945024A proposes a composite kinetic energy projectile with coupled spin stabilization and drag stabilization. It uses a front warhead, middle projectile body, and rear projectile body designed with adhesive bonding at the front and rear. The rear projectile body incorporates a projectile band and canted tail fins, combining spin and drag stabilization to improve accuracy and initial velocity consistency. Increasing range can also be achieved by adding acceleration devices.Patent CN113607007A describes a composite kinetic energy projectile with sensor-controlled secondary acceleration. It uses a built-in sensor to detect the projectile's flight distance and controls the activation of a secondary propulsion device to achieve secondary acceleration. Patent CN113587736A proposes a composite kinetic energy projectile with a delayed boost function. Through a built-in delay tube and a spreader charge, it achieves delayed boost during flight, increasing the projectile's initial velocity and effective range.

[0004] Non-lethal kinetic energy rounds still suffer from inconsistent power and insufficient accuracy. Current methods to address these issues include variable muzzle velocity technology, structural modifications, material replacement, and velocity control. Variable muzzle velocity technology primarily alters the projectile's initial velocity through firearm design, resulting in complex structures and poor versatility. Structural modifications mainly involve changing the projectile's shape, adjusting power through contact area and contact method, but this cannot maintain a constant power output. Material replacement involves using softer, more deformable materials, sacrificing usability. Velocity control, inspired by rocket design, increases range but narrows the effective area and makes the power prone to being too high or too low. Therefore, current solutions often only expand the usability range or compromise on power, failing to fundamentally address the issue of balancing excessive damage with usability. Summary of the Invention

[0005] Therefore, the technical problem to be solved by the present invention is to provide a non-lethal kinetic energy projectile with stable impact, which can ensure a relatively constant impact force over a wide range, thereby fundamentally solving the problem of matching excessive damage with the effectiveness of use.

[0006] To solve the above-mentioned technical problems, the present invention provides the following technical solution:

[0007] A non-lethal kinetic energy projectile with stable impact, comprising:

[0008] The upper body has a built-in airbag system for providing a stable impact force and a fuse system for controlling the airbag deployment time; the airbag system includes an airbag and a gas generator, which generates gas to inflate the airbag; the fuse system includes a pulsed laser ranging module, a control module, a power supply, an electric ignition device, and an ignition propellant.

[0009] The lower body has a built-in launching system for launching projectiles, which includes a primer and propellant;

[0010] The upper and lower projectiles are detachably assembled and connected; after the non-lethal kinetic energy ejection of the airbag with stable impact is launched, the upper and lower projectiles separate; when the distance between the front end of the upper projectile and the target receiver measured by the pulse laser ranging module is within the threshold range, the control module activates the electric ignition device and uses the electric ignition device to ignite the ignition propellant, the ignition propellant ignites the gas generator, the gas generator produces gas and causes the airbag to be ejected from the top of the upper projectile.

[0011] The aforementioned airbag-emerged non-lethal kinetic energy projectile with stable impact also includes a middle projectile with a flight stabilization system at its tail. The upper and lower projectiles are detachably connected via the middle projectile. After the airbag-emerged non-lethal kinetic energy projectile with stable impact is launched, the middle projectile and the lower projectile separate. When the middle and lower projectiles are not separated, the lower section of the flight stabilization system is located in the cavity between the top of the lower projectile and the middle projectile. After the middle and lower projectiles separate, one end of the flight stabilization system is placed outside the middle projectile.

[0012] The aforementioned airbag-emerged non-lethal kinetic energy projectile with stable impact has a flight stabilization system including a folding tail fin mechanism. After the middle and lower projectiles separate, the folding tail fin mechanism automatically opens under inertia, with one end of the folding tail fin mechanism located outside the middle projectile.

[0013] The aforementioned airbag-emerged non-lethal kinetic energy projectile with stable impact has a sabot inside the lower projectile body; the lower section of the flight stabilization system is located in the cavity between the sabot and the middle projectile body.

[0014] The aforementioned airbag-emerged non-lethal kinetic energy projectile with stable impact comprises an outer shell and an inner shell. The outer shell has a transparent window at its front end and two or more outward-facing through slots along its circumference. The thickness of the outer shell between the bottom of the through slots and the inner wall of the outer shell is 0.2–0.3 mm. The inner shell comprises an upper shell, a middle shell, and a lower shell, which are fixedly connected in sequence. A first partition is provided between the upper and middle shells, and a second partition is provided between the middle and lower shells. The second partition has a one-way air-tightening mechanism. A pulsed laser ranging module is located at the top of the upper shell, and a control module is located in the middle section of the upper shell. The power supply and... The electric ignition devices are respectively installed in the lower section of the upper shell and the ignition head of the electric ignition device is installed in the middle section shell. The ignition propellant is installed in the middle section shell and the gas generating agent is installed in the lower section shell. The gas bag is installed in the cavity between the outer shell and the inner shell. The gas bag and the lower shell are connected by a vent hole on the shell wall of the lower shell. After the electric ignition device ignites the ignition propellant, the burning ignition propellant forms a hot spot and ignites the gas generating agent through the one-way gas-closing mechanism. The gas generated by the burning gas generating agent enters the gas bag through the vent hole and fills the gas bag. The filled gas bag is squeezed and causes the outer shell to rupture along the through groove and pops out from the cavity between the outer shell and the inner shell.

[0015] The aforementioned airbag-emerged non-lethal kinetic energy projectile with stable impact has its airbag positioned in the cavity between the outer shell and the inner shell in a planar folding, roll-up folding, circumferential tightening folding, or absorption folding manner.

[0016] The aforementioned airbag-type non-lethal kinetic energy projectile with stable impact has a conical gas guide hole and a constricted end near the gas generator.

[0017] The aforementioned airbag-emerged non-lethal kinetic energy projectiles with stable impact have a threshold range of 100–150 cm.

[0018] The aforementioned airbag-emerged non-lethal kinetic energy projectile with stable impact has an airbag capacity of 0.84–2.36 L, and the airbag is an ellipsoidal airbag with a major axis of 10 cm and a minor axis of 4.5–7.5 cm; the gas generator has a combustion rate of 0.867 mm / s, an explosion temperature of 1901 K, a gas production rate of 0.67 L / g, and a gas generator dosage of 1.25–3.5 g.

[0019] The aforementioned airbag-type non-lethal kinetic energy projectile, which possesses stable impact, uses a guanidine nitrate-based gas generator as its gas generator.

[0020] The technical solution of the present invention achieves the following beneficial technical effects:

[0021] 1. Good versatility. The ammunition used in this invention has a caliber of 38mm, which is compatible with 38mm firing devices;

[0022] 2. Constant power. The power received by the target within the specified range remains constant, avoiding the problems of excessive damage and insufficient power. Attached Figure Description

Detailed Implementation

[0028] like Figures 1-3As shown, the non-lethal kinetic energy projectile with stable impact, comprising an upper projectile body 100 and a lower projectile body 200, comprises two parts. The upper projectile body 100 houses an airbag system for providing a stable impact force and a fuze system for controlling the deployment time of the airbag 106. The airbag system includes a gas generator 112 and an airbag 106 with a capacity of 0.84–2.36 L. The gas generator 112 generates gas to inflate the airbag 106. The airbag 106 is an ellipsoidal airbag with a major axis of 10 cm and a minor axis of 4.5–7.5 cm. The fuze system includes a pulsed laser ranging module 107, a control module 108, a power supply 110, an electric ignition device 109, and an ignition charge 111. The lower projectile body 200 houses a launching system for launching the projectile. The system includes a primer 202 and a propellant 203; the upper projectile 100 and the lower projectile 200 are detachably connected; after the non-lethal kinetic energy ejection with stable impact is launched, the upper projectile 100 and the lower projectile 200 separate; when the distance between the front end of the upper projectile 100 and the target receiver measured by the pulse laser ranging module 107 is within the threshold range of 100-150cm, the control module 108 activates the electric ignition device 109 and uses the electric ignition device 109 to ignite the ignition propellant 111, the ignition propellant 111 ignites the gas generator 112, the gas generator 112 generates gas and causes the airbag 106 to be ejected from the top of the upper projectile 100. The control module 108 includes an STM32L031 K6 central processing unit, an MPU-6050 accelerometer module, and an AMS1117 power management chip. The pulsed laser ranging module 107 is an ID-R laser sensor, and the electric ignition device 109 is a YF-29 pulsed arc igniter. In this invention, the accelerometer acts as a switch (or safety mechanism) for the pulsed laser ranging module. When the acceleration of a stable impact, airbag-emerged non-lethal kinetic energy projectile reaches a certain threshold, the projectile is launched by default, and the pulsed laser ranging module begins to operate.

[0029] Specifically, such as 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 has a transparent window 115. The outer shell 101 has two or more outward-facing through slots 117 arranged along its circumference. The thickness of the outer shell 101 between the bottom of the through slots 117 and the inner wall of the outer shell 101 is 0.2–0.3 mm, preferably 0.25 mm. The inner shell includes an upper shell 102, a middle shell 103, and a lower shell 104, which are sequentially fixedly connected. The upper shell 102 and the middle shell... A first partition 116 is provided between the bodies 103, and a second partition is provided between the middle section shell 103 and the lower section shell 104. A one-way airtight mechanism 114 is provided on the second partition. A pulsed laser ranging module 107 is located at the top inside the upper section shell 102, and a control module 108 is located in the middle section of the upper section shell 102. A power supply 110 and an electric ignition device 109 are respectively located in the lower section of the upper section shell 102, with the ignition head of the electric ignition device 109 located in the middle section shell 103. An ignition propellant 111 is located in the middle section shell 103. The gas generator 112 is disposed within the lower housing 104; the airbag 106 is disposed in the cavity between the outer housing 101 and the inner housing by means of planar folding, roll folding, circumferential tightening folding, or absorption folding, and the airbag 106 and the lower housing 104 are fluidly connected through the air guide hole 105 provided on the shell wall of the lower housing 104; after the electric ignition device 109 ignites the ignition powder 111, the ignition powder 111 in the combustion state forms a hot spot, which ignites the gas generator 112 through the one-way gas-closing mechanism 114, and the gas in the combustion state... The gas generated by the gas generator 112 enters the air bladder 106 through the air guide hole 105 and inflates the air bladder 106. After the inflated air bladder 106 is squeezed and the outer shell 101 is ruptured along the through groove 117, it 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 constricted end. In order to prevent solid residue generated by the gas generator 112 from entering the air guide hole 105 and blocking the air guide hole 105, a filter screen 113 is provided on the inner wall of the lower shell 104.

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

[0031] To ensure the stability of the airbag-emerged non-lethal kinetic energy projectile with stable impact during flight, this embodiment adds a middle projectile body 300 with a flight stabilization system at its tail. The upper projectile body 100 and the lower projectile body 200 are detachably connected via the middle projectile body 300. After the airbag-emerged non-lethal kinetic energy projectile with stable impact is launched, the middle projectile body 300 separates 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 located in the cavity between the top of the lower projectile body 200 and the middle projectile body 300. Figure 2As shown, after the middle missile body 300 separates from the lower missile body 200, one end of the flight stabilization system is positioned outside the middle missile body 300. The flight stabilization system includes a folding tail fin mechanism 400. After the middle missile body 300 separates from the lower missile body 200, the folding tail fin mechanism 400 automatically opens under inertia, with one end of the folding tail fin mechanism 400 positioned outside the middle missile body 300 to increase range and improve accuracy.

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

[0033] In this invention, the launching system is responsible for launching the projectile, conforming to the design specifications of 38mm ammunition; the airbag 106 system is the source of lethal force, with a target force that does not cause penetrating or piercing damage; the fuse system controls the deployment time of the airbag 106, detonating it at a distance of 100-150cm from the target. Upon deployment, the airbag 106 generates a lateral pressure. The rearward pressure counteracts the kinetic energy of the stable-impact airbag-launched non-lethal kinetic energy projectile, while the forward pressure ensures that the airbag 106 applies the required impact force to the target, thus ensuring a constant force on the target. During firing, the ammunition is loaded into the grenade launcher after being aimed at the target and then fired. The firing pin ignites the primer 202, which in turn ignites the propellant 203, ejecting a non-lethal kinetic energy ejection system with a stable impact. Simultaneously, the gas generated by the propellant 203 enters the cavity between the sabot 204 and the bottom of the lower cartridge case through the ignition port 205, creating high pressure that causes the lower cartridge case to separate from the middle cartridge 300, resulting in the jettisoning of the lower cartridge 200. After the non-lethal kinetic energy ejection system with a stable impact is ejected, the folding tail fin mechanism 400 deploys to ensure flight stability. Due to the inertia of launch, the safety is released, the power supply 110 is powered, and the pulse laser ranging module 107 continues to work. When the distance to the target receiver is detected to be 100-150cm, the ignition signal is transmitted to the electric ignition device 109. The electric ignition device 109 ignites the ignition propellant 111, which further ignites the gas generator 112. The burning gas generator 112 produces a large amount of gas within 30ms and fills the gasbag 106. The filled gasbag 106 bursts through the outer shell 101 and generates a thrust backward to offset the impact kinetic energy of the gasbag ejection non-lethal kinetic energy projectile with stable impact. At the same time, it generates a thrust forward and then the filled gasbag 106 hits the target.

[0034] Specifically, the launch system in this invention uses the same primer 202 and propellant 203 as the 38mm kinetic energy projectile. The gas generator 112, electric ignition device 109, and lower casing 104 constitute a gas generator. A fuze system controls the timing of the gas generator's activation, ensuring it starts at the appropriate time. Currently, the gas generator 112 mainly consists of a high-nitrogen-content gas-producing fuel and common oxidizers, with some additives added depending on the operating environment. Gas generators 112 are typically classified according to the type of gas-producing fuel, and their performance is adjusted by adding different oxidizers. Common gas generator 112 components are shown in Table 1.

[0035] Table 1. Components of Common Gas Generators

[0036]

[0037]

[0038] The gas generator 112 used in this invention is a guanidine nitrate-based gas generator, 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 formulated with this method has a combustion rate of 0.867 mm / s, an explosion temperature of 1901 K, a gas production rate of 0.67 L / g, and a dosage of 1.25–3.5 g.

[0039] The airbag 106 uses the same material as the current automotive driver's side airbag 106, made of nylon 6.6 fabric with a thickness of 0.35mm ± 0.05mm. The main folding methods for the airbag 106 include flat folding, roll folding, circumferential tightening folding, and absorbent folding.

[0040] Because the ignition time of the gas generator 112 needs to be precisely controlled, this invention employs a pulsed laser ranging module 107 to measure the distance between the upper projectile 100 and the target receiver during flight. The pulsed laser ranging module 107 uses an optical emitting system to illuminate the target with a specific laser beam, while simultaneously using an optical receiving system to receive the diffusely reflected laser echo from the target and process the received optical signals. When the fuse identifies the target and is within the optimal detonation point range, a detonation signal is generated by the control module 108, activating the electric ignition device 109 for ignition. Pulsed laser ranging typically uses a high-speed counter to measure the return time of the laser pulse. Under the action of a drive signal, the laser emits a pulsed laser, and simultaneously feeds back a signal to the signal processing unit as the timing start time. The laser pulse illuminates the target through the emitting optical system. The laser echo pulse signal reflected from the target is converted into an electrical signal by a photodetector, amplified and shaped, and used as the timing termination time of the counter. The counting result multiplied by the counting period is the round-trip time of the laser pulse.

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

[0042]

[0043] In the formula, c is the speed of light in air; neglecting atmospheric effects, c = 2.9971 × 10⁻⁶ 8 m / s.

[0044] When the pulsed laser ranging module 107 measures the distance between the upper projectile 100 and the target recipient and the control module 108 generates a detonation signal, considering the gas generation speed and total duration of the gas generator 112, as well as the flight speed and speed decay of the airbag-emerged non-lethal kinetic energy projectile with stable impact, and also considering the magnitude of the impact of the airbag-emerged non-lethal kinetic energy projectile with stable impact on the target recipient, in this invention, the control module 108 generates a detonation signal when the distance between the upper projectile 100 and the target recipient is measured by the pulsed laser ranging module 107 to be between 100 and 150 cm. In this case, it can be ensured that the outer shell 101 will not hit the target recipient, while ensuring that when the airbag 106 breaks through the outer shell 101 and hits the target recipient, it can deliver a non-lethal impact to the target recipient. At this time, the impact force of the airbag-emerged non-lethal kinetic energy projectile with stable impact on the target recipient mainly comes from the impact force formed when the airbag 106 is ejected from the outer shell 101.

[0045] When using this invention to fire at a target, the part of the non-lethal kinetic energy projectile with stable impact that contacts the target is the airbag 106 ejected from the upper projectile body 100. Compared to conventional kinetic energy projectiles, this not only has a relatively large contact area but also better flexibility. While ensuring an effective impact on the target, it does not cause fatal damage. This is because the high-speed movement of the airbag 106 generates a significant impact on the target, causing injury. However, the large contact area between the airbag 106 and the target results in a relatively small pressure per unit area, preventing severe destructive damage. Furthermore, the airbag 106 is a flexible material, and the gas is compressible, meaning the impact is not released instantly but takes time to dissipate. This maintains the impact of the airbag 106 on the target at a non-lethal level, ensuring the target's safety.

[0046] Obviously, the above embodiments are merely illustrative examples for clear explanation and are not intended to limit the implementation. Those skilled in the art will recognize that other variations or modifications can be made based on the above description. It is neither necessary nor possible to exhaustively list all possible implementations here. However, obvious variations or modifications derived therefrom are still within the scope of protection of the claims of this patent application.
