Description

Technical Field

[0001] This invention relates to the field of ballistic testing technology, specifically to a lightweight sabot and ballistic stabilization device suitable for light gas gun systems. Background Technology

[0002] Light gas guns, as launching devices capable of generating ultra-high speeds (typically greater than 1 km / s), are widely used in research fields such as impact dynamics and spacecraft protection. During launch, due to the varying shapes of the projectiles, sabots are typically used to adapt and support them.

[0003] A published patent CN204240872U discloses a toothed meshing elastic separation sabot, which aims to solve the problem that existing integral cylindrical sabots cannot separate autonomously after leaving the launch tube, and rely solely on gas resistance to separate the sabot from the supercavitating launcher. Furthermore, the sabot's separation effect is unstable after entering water, and it has a significant impact on the launch channel of the supercavitating launcher, resulting in large errors in experimental research results.

[0004] However, existing sabot structures have the following significant drawbacks: Excessive mass: Traditional metal or pure nylon sabots are quite heavy, consuming a large amount of launch energy as parasitic mass and increasing friction on the barrel wall, leading to severe barrel wear; Difficult separation: Existing sabots mostly adopt an integral or simple segmented structure, relying on air resistance for natural separation. Under ultra-high speed conditions, this separation method is often delayed, and may even result in the sabot impacting the projectile's tail, severely affecting the projectile's target accuracy; Poor stability: The lack of effective constraint on the projectile's base makes it prone to slight wobbling during its movement within the barrel, resulting in large initial muzzle disturbance after exiting the gun.

[0005] Therefore, there is an urgent need for a lightweight sabot and ballistic stabilization device for a lightweight gas gun system to solve the above-mentioned technical problems. Summary of the Invention

[0006] (a) Technical problems to be solved To address the shortcomings of existing technologies, this invention provides a lightweight sabot and ballistic stabilization device suitable for light gas gun systems. It has the advantages of lightweight sabot, ballistic stabilization, and no sabot tail impact on the projectile, and solves the problems of heavy sabot weight, severe barrel wear, and difficulty in separating the sabot from the projectile.

[0007] (II) Technical Solution To achieve the above objectives, the present invention provides the following technical solution: Lightweight sabots and ballistic stabilizing devices suitable for light gas gun systems include: The sabot is a segmented structure that covers the bottom of the projectile. The outer circumferential surface of the sabot has multiple spiral gas grooves, and the inner surface of the sabot has an engaging and sealing connection. A magnetic stabilizing assembly includes a radial magnetic attracting element embedded in the inner wall of the projectile and a magnetic ring disposed at the bottom of the projectile. The magnetic attracting element in the inner wall of the projectile and the magnetic ring at the bottom of the projectile form a magnetic attraction engagement. An auxiliary detachment assembly is disposed at the exit end of the gun barrel. The auxiliary detachment assembly includes an annular guide plate located on one side of the exit end of the gun barrel. A clamping part for clamping the dividing blade is disposed between the annular guide plate and the exit end of the gun barrel. An inclined surface is disposed on the annular guide plate behind the dividing blade. The dividing blade is used to cut off the segmented connection of the sabot, and the inclined surface of the annular guide plate is used to guide the cut sabot segments to flip outward and fall off.

[0008] Preferably, the sabot is made of carbon fiber reinforced resin composite material.

[0009] Preferably, the spring-loaded support includes a first segment and a second segment, and the magnetic attractant includes a second N-pole magnetic block disposed on the inner wall of the bottom of the first segment and a second S-pole magnetic block disposed on the inner wall of the bottom of the second segment.

[0010] Preferably, the plurality of spiral air guide grooves are distributed at equal intervals on the outer surface of the sabot, and the top of the sabot is provided with an outer slope wall and an inner slope wall.

[0011] Preferably, the inner slope wall has a plurality of arc-shaped guide ribs arranged in a circular array, and the spiral direction of the guide ribs is opposite to the spiral direction of the spiral air guide groove.

[0012] Preferably, the meshing sealing connection includes serrated portions disposed at the bottom of the first and second segments.

[0013] Preferably, the outer diameter of the sabot is smaller than the inner diameter of the gun barrel, and a micro-gap is formed between the outer surface of the sabot and the inner wall of the gun barrel.

[0014] Preferably, the auxiliary detachment assembly further includes a first N-pole magnetic block and a first S-pole magnetic block, which are symmetrically arranged on the inner wall of the exit end of the barrel.

[0015] Preferably, the annular guide plate includes two symmetrically arranged C-shaped rings, each of which has two clamping parts at both ends, and an installation gap is provided between two adjacent clamping parts. The dividing blade is inserted into the installation gap between the two clamping parts and locked by a fastening bolt.

[0016] Preferably, there is a gap between the barrel exit end and the annular guide plate, and the center line of the first N-pole magnetic block and the first S-pole magnetic block is perpendicular to the connecting line of the two dividing blades.

[0017] (III) Beneficial Effects Compared with the prior art, the present invention provides a lightweight sabot and ballistic stabilization device suitable for light gas gun systems, which has the following advantages: 1. This lightweight sabot and ballistic stabilization device, applicable to light gas gun systems, features a sabot with multiple equally spaced serrations on its inner wall. The tooth tip rounded corners, tooth flank angles, and tooth pitch are set according to the material and roughness of the projectile's base. A ring-shaped permanent magnet or multiple fan-shaped magnets are embedded behind the serrated area, forming a closed radial magnetic circuit with the ferromagnetic layer at the bottom of the projectile. The magnetic preload is determined by the chamber pressure, initial velocity, and mass ratio. The axial positions of the serrations and the magnetic ring are staggered to avoid concentrated force at the same point. The bonding interface uses a wear-resistant coating or micro-texture to control the coefficient of friction and thermal erosion. The radial and circumferential restraints in the initial stage of sabot launch are significantly enhanced, reducing projectile pitch / yaw disturbances. Relative slip is controlled, and base wear and local hot spots are reduced. Batch repeatability and initial attitude consistency are improved, laying the boundary conditions for subsequent flight stability and separation reliability.

[0018] 2. This lightweight sabot and ballistic stabilization device, applicable to light gas gun systems, features multiple equidistant spiral gas guide grooves machined on the outer wall of the sabot. The propellant gas forms a controlled vortex and tangential momentum distribution along the grooves, weakening the lateral moment caused by asymmetric airflow and the micro-geometry of the tube wall, thus constructing a passively self-rectifying steady-state boundary layer. The spiral gas guide grooves employ multi-head spirals with small depth and width, and the lead and spiral angle are designed in conjunction with the bore diameter, chamber pressure rise rate, and expected initial velocity. Rounded corners at the groove roots and chamfered edges at the groove openings reduce stress concentration and erosion wear. The groove rows and segmented joints are staggered to avoid weakening the cross-section. A transition section is set at the front and rear ends of the sabot to reduce the axial pressure fluctuation induced by the channel. The spiral direction of the arc-shaped guide rib on the inner slope wall of the sabot top is opposite to that of the spiral gas guide groove, forming a reverse flow for the high-pressure gas in the chamber, further optimizing the gas flow state, reducing the interference of airflow turbulence on the projectile's motion attitude, ensuring that the sabot accelerates smoothly along the axis in the chamber, and the force on the sabot in the chamber is more balanced, reducing the sabot's lateral deflection and self-excited vibration, and decreasing the peak pressure and wear of the tube wall contact pressure; the trajectory dispersion converges, the exit attitude is more stable, and the stability of the attitude boundary before separation is improved.

[0019] 3. This lightweight sabot and ballistic stabilization device, applicable to light gas gun systems, allows the sabot and projectile to reach the barrel exit end. When the sabot and projectile move to this point, the segmented connection of the sabot contacts the dividing blade. The high-speed moving sabot is sheared by the dividing blade, severing the connection between the segments. Simultaneously, due to the gap between the annular guide plate and the barrel exit end, the first N-pole magnetic block and the first S-pole magnetic block symmetrically arranged on the inner wall of the barrel exit end repel the second N-pole magnetic block and the second S-pole magnetic block on the inner wall of the sabot, thus facilitating the repulsion of the second N-pole magnetic block and the second S-pole magnetic block on the inner wall of the sabot. The guide plate acts as a fulcrum, causing the first and second segments to separate along the shearing direction of the dividing blade, thus improving the cutting and separation effect. The inclined surface of the annular guide plate is located behind the dividing blade. The cut sabot segments come into contact with the inclined surface under the action of inertia. The guiding effect of the inclined surface forces the sabot segments to flip outward. The trajectory of the sabot fragments is effectively decoupled from the main trajectory of the projectile, and the probability of tail hit is significantly reduced. The sabot separation impact causes little disturbance to the attitude of the projectile, improving the stability of the external trajectory and the accuracy of the hit, and enhancing the safety of the target range and the maintainability of the equipment.

Thus, a feature defined as "first" or "second" may explicitly or implicitly include one or more of that feature. In the description of this invention, "a plurality of" means two or more, unless otherwise explicitly specified.

[0039] This embodiment provides a lightweight sabot and ballistic stabilization device suitable for a light gas gun system, and has the following technical features.

[0040] Please see Figures 1 to 14 A lightweight sabot and ballistic stabilization device suitable for a light gas gun system, comprising: a sabot 2, which is a segmented structure covering the bottom of the projectile 3, with multiple spiral gas guide grooves 203 on the outer circumferential surface of the sabot 2, and an engaging sealing connection part on the inner surface of the sabot 2. The magnetic stabilizing component includes a radial magnetic attracting element embedded in the inner wall of the projectile 2 and a magnetic ring 301 disposed at the bottom of the projectile 3. The magnetic attracting element on the inner wall of the projectile 2 and the magnetic ring 301 at the bottom of the projectile 3 form a magnetic adsorption engagement. Among them, the dividing blade 4 is used to cut off the segmented connection part of the sabot 2, and the inclined surface 503 of the annular guide plate 5 is used to guide the cut sabot 2 segments to flip outward and fall off.

[0041] The sabot 2 is made of carbon fiber reinforced resin composite material.

[0042] It should be noted that the sabot 2 has a segmented structure and is made of high-strength composite materials (such as carbon fiber reinforced resin) to ensure that the total mass of the sabot 2 is less than 15% of the mass of the projectile 3, thus significantly reducing parasitic mass. It is composed of the first segment 201 and the second segment 202. The second N-pole magnetic block 208 and the second S-pole magnetic block 209 on the bottom inner wall of the sabot 2 form a magnetic adsorption fit with the magnetic ring 301 at the bottom of the projectile 3. At the same time, the serrated part 204 at the bottom of the sabot 2 segments meshes with the sealing connection part to achieve a tight connection and seal between the sabot 2 and the projectile 3, preventing high-pressure gas from leaking from the gap between the projectile 3 and the sabot 2 when the light gas gun is fired.

[0043] An auxiliary detachment assembly is provided at the exit end of the barrel 1. The auxiliary detachment assembly includes an annular guide plate 5 located on one side of the exit end of the barrel 1. A clamping part 502 for clamping the dividing blade 4 is provided between the annular guide plate 5 and the exit end of the barrel 1. An inclined surface 503 located behind the dividing blade 4 is provided on the annular guide plate 5. The spring support 2 includes a first segment 201 and a second segment 202. The magnetic attractor includes a second N-pole magnetic block 208 disposed on the bottom inner wall of the first segment 201 and a second S-pole magnetic block 209 disposed on the bottom inner wall of the second segment 202.

[0044] Multiple spiral air guide grooves 203 are evenly distributed on the outer surface of the sabot 2, and the top of the sabot 2 is provided with an outer slope wall 205 and an inner slope wall 206.

[0045] The inner slope wall 206 has a circular array of multiple arc-shaped guide ribs 207, and the spiral direction of the guide ribs 207 is opposite to the spiral direction of the spiral air guide groove 203.

[0046] The meshing sealing connection includes a serrated portion 204 disposed at the bottom of the first segment 201 and the second segment 202.

[0047] The angle of the splitting blade 4 is designed to be 30°-45°, which is used to cut off the split connection of the sabot 2 the moment it flies out of the gun barrel 1.

[0048] An inclined surface 503 of an annular guide plate 5 is set immediately behind the dividing blade 4. The inclined surface 503 has an inclination angle of 15°. The high-speed inertia of the projectile 3 forces the cut-off sabot 2 to flip outward rapidly along the inclined surface 503 of the annular guide plate 5, thereby achieving physical separation of the sabot 2 from the projectile 3.

[0049] The outer diameter of the sabot 2 is smaller than the inner diameter of the barrel 1, and a micro-gap 6 is formed between the outer surface of the sabot 2 and the inner wall of the barrel 1.

[0050] It should be noted that the outer diameter of the sabot 2 is designed to be 0.1-0.3 mm smaller than the inner diameter of the barrel 1, forming a micro-gap 6 fit. Under the premise of ensuring airtightness, the friction coefficient is reduced by about 40%. The high-pressure gas generated by the light gas gun pushes the sabot 2 and the projectile 3 along the barrel 1. The outer diameter of the sabot 2 is smaller than the inner diameter of the barrel 1, forming a micro-gap 6 between them. After some of the high-pressure gas enters the micro-gap 6, it flows through the spiral air guide grooves 203 evenly distributed on the outer circumferential surface of the sabot. The spiral airflow will generate a propulsive force along the barrel axis and a circumferential stabilizing torque, which counteracts the deflection tendency of the projectile in the barrel. Meanwhile, the spiral direction of the arc-shaped guide rib 207 on the inner slope wall 206 at the top of the sabot 2 is opposite to that of the spiral gas guide groove 203, forming a reverse flow for the high-pressure gas in the chamber, further optimizing the gas flow state, reducing the interference of airflow turbulence on the motion attitude of the projectile 3, and ensuring that the sabot 2 accelerates smoothly along the axis in the chamber.

[0051] The auxiliary detachment assembly also includes a first N-pole magnetic block 101 and a first S-pole magnetic block 102, which are symmetrically arranged on the inner wall of the exit end of the barrel 1.

[0052] The annular guide plate 5 includes two symmetrically arranged C-shaped rings 501. Each C-shaped ring 501 has two clamping parts 502 at both ends. There is an installation gap between two adjacent clamping parts 502. The dividing blade 4 is inserted into the installation gap between the two clamping parts 502 and locked by a fastening bolt.

[0053] There is a gap between the exit end of the gun barrel 1 and the annular guide plate 5. The center lines of the first N-pole magnetic block 101 and the first S-pole magnetic block 102 are perpendicular to the connecting line of the cutting edges of the two dividing blades 4.

[0054] It should be noted that when the sabot 2 and the projectile 3 move to the exit end of the gun barrel 1, they will pass through the key structure of the auxiliary detachment component: the annular guide plate 5 at the exit end of the gun barrel 1 and the clamping part 502 between the gun barrel 1 and the gun barrel 1 are fixed with a dividing blade 4. The segmented connecting part of the sabot 2 will come into contact with the dividing blade 4. The high-speed moving sabot 2 is subjected to the shearing action of the dividing blade 4, and the connection between the segments is cut off.

[0055] Meanwhile, since there is a gap between the annular guide plate 5 and the exit end of the gun barrel 1, the first N-pole magnetic block 101 and the first S-pole magnetic block 102 symmetrically arranged on the inner wall of the exit end of the gun barrel 1 will generate like-pole repulsion on the second N-pole magnetic block 208 and the second S-pole magnetic block 209 on the inner wall of the sabot 2. Combined with the fulcrum effect of the annular guide plate 5, the first segment 201 and the second segment 202 are separated along the shearing direction of the dividing blade 4, which improves the cutting and separation effect. The inclined surface 503 of the annular guide plate 5 is located behind the dividing blade 4. The cut sabot 2 segments come into contact with the inclined surface 503 under the action of inertia. The guiding effect of the inclined surface 503 forces the sabot 2 segments to flip outward and separate from the bottom of the projectile 3, so that the sabot 2 is separated from the core area of ​​the trajectory and avoids secondary interference caused by tail impact on the projectile 3.

[0056] In summary, this lightweight sabot and ballistic stabilization device, suitable for light gas gun systems, significantly enhances radial and circumferential restraint in the initial firing phase, reducing pitch / yaw disturbances in the projectile 3; relative slip is controlled, reducing bottom band wear and local hot spots; batch repeatability and initial attitude consistency are improved, laying the boundary conditions for subsequent flight stability and separation reliability; the sabot 2 experiences more balanced forces within the barrel, reducing lateral deflection and self-excited vibration; peak contact pressure and wear on the barrel wall decrease; the ballistic dispersion converges, resulting in a more stable exit attitude and improved attitude boundary stability before separation; the sabot 2's segmented trajectory is effectively decoupled from the projectile 3's main trajectory, significantly reducing the probability of tail hits; the separation impact causes minimal attitude disturbance to the projectile 3, improving external ballistic stability and hit accuracy, and enhancing range safety and equipment maintainability.

Furthermore, the terms "comprising," "including," or any other variations thereof are intended to cover non-exclusive inclusion, such that a process, method, article, or apparatus that comprises a list of elements includes not only those elements but also other elements not expressly listed, or elements inherent to such a process, method, article, or apparatus.
