Description
Technical Field
[0001] The invention relates to the technical field of light gas guns, in particular to a flexible support device for collision-separated projectiles and a light gas gun experimental device. Background Art
[0002] As a device used for experiments such as high-speed projectile penetration of target plates, the sabot plays a vital role in the light gas gun. It can not only guide the projectile in the barrel and transmit high-pressure gas pressure to make the projectile obtain a higher initial velocity, but also effectively separate from the projectile after exiting the muzzle to avoid the sabot's additional destructive effect on the target plate. The accuracy and reliability of the experimental results of the light gas gun directly depend on the design and performance of the sabot.
[0003] The application of sabots in light gas gun experiments has been widely recognized and adopted. Through the support and guidance of sabots, light gas guns can achieve precise acceleration of projectiles of various shapes and sizes, thereby conducting high-speed collision experiments, target plate penetration experiments, etc.
[0004] At present, sabot separation technology can be mainly divided into two types: forced separation and pneumatic separation. The forced separation technology uses a mechanical device to block the sabot and separate it from the projectile. This technology is simple to operate, can effectively control the separation process, and has high experimental controllability; the pneumatic separation technology uses the air resistance in the target chamber to separate the sabot from the projectile. Compared with the forced separation technology, the pneumatic separation technology avoids the influence of the mechanical device on the projectile, making the projectile more stable and suitable for experiments in the atmosphere. However, the existing sabot separation technology also has some shortcomings. The forced separation technology is prone to cause the projectile to break and the separation failure, affecting the accuracy and reliability of the experimental results. At the same time, because the pneumatic separation technology is limited by environmental conditions, it cannot be applied to experiments in a vacuum environment, and it is easily affected by air resistance, which limits its applicability in experiments.

Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.
[0028] The purpose of the present invention is to provide a flexible support device for collision separation of projectiles and a light gas gun experimental device, so as to solve the problems existing in the prior art and improve the accuracy and reliability of light gas gun experiments.
[0029] In order to make the above-mentioned objects, features and advantages of the present invention more obvious and easy to understand, the present invention is further described in detail below with reference to the accompanying drawings and specific embodiments.
[0030] Embodiment 1
[0031] like Figure 1-Figure 3 As shown, the present embodiment provides a flexible cartridge device for collision separation of projectiles, comprising a bullet cartridge 1 and a cartridge block 2. The bullet cartridge 1 is hollow inside, and a circle of flexible clamping elements is provided on the inner wall of the bullet cartridge 1. The flexible clamping elements are used to clamp the projectile 4, and then before the projectile 4 is fired, the projectile 4 is limited by the flexible clamping elements. The cartridge block 2 is hollow inside and can be used for the projectile 4 to pass through, so that the projectile 4 can be fired smoothly. A blocking element is provided at one end of the cartridge block 2. When firing, the projectile 4 is fired synchronously with the cartridge block 2. When the bullet cartridge 1 moves to contact with the cartridge block 2, the blocking element can act on The flexible clamping element makes the bullet sabot 1 and the sabot block 2 move synchronously until the blocking element drives the flexible clamping element to deform to release the clamping of the projectile 4, and passes through the middle part of the sabot block 2, thereby realizing the rapid separation of the projectile 4 from the bullet sabot 1, reducing the influence on the movement trajectory of the projectile 4 and improving the shooting accuracy. At the same time, the soft release of the projectile 4 is realized through collision, thereby improving the accuracy and reliability of the launch of the projectile 4. Through the above design, this embodiment has good sealing performance, enhances the stability of the bullet sabot 1 and the projectile 4 in the barrel 7, is suitable for light gas gun launch, and improves the shooting accuracy and reliability.
[0032] Specifically, a receiving groove 11 with an opening on one side is provided inside the bullet cartridge case 1, so as to provide a receiving space for the projectile 4. The opening of the receiving groove 11 is opened toward the cartridge case block 2 to ensure that the projectile 4 can be ejected. The flexible snap-on element is installed in the receiving groove 11.
[0033] The flexible clamping element includes a deformable support ring 12 and a clamping ring wall 13. Along the ejection direction of the projectile 4, the diameter of the deformable support ring 12 gradually increases, and then under the action of the blocking element, the small end of the deformable support ring 12 gradually opens, and drives the clamping ring wall 13 to deform and expand, thereby releasing the projectile 4 and separating the clamping ring wall 13 from the projectile 4. The small end of the deformable support ring 12 extends toward the inner bottom surface of the accommodating groove 11, and the small end of the deformable support ring 12 does not contact the inner bottom surface of the accommodating groove 11. The internal suspended design enables the deformable support ring 12 to deform inwardly first when colliding with the support ring wall, thereby realizing the rapid separation of the bullet support 1 and the projectile 4, and the large end of the deformable support ring 12 is in contact with the side of the accommodating groove 11. The wall is fixed as a whole; the clamping ring wall 13 is cylindrical, preferably an intermittent cylindrical shape, that is, the clamping ring wall 13 is formed by splicing a plurality of arc-shaped walls at intervals, and the deformation support ring 12 is preferably an intermittent truncated cone. The first end of the clamping ring wall 13 is fixed as a whole with the small end of the deformation support ring 12, so that the clamping of the projectile 4 can be relaxed under the drive of the deformation support ring 12, and the second end of the clamping ring wall 13 extends to the opening of the accommodating groove 11; the clamping ring wall 13 is used to clamp the projectile 4, and the clamping ring wall 13 and the projectile 4 are interference fit, which can effectively clamp the projectile 4 and prevent the projectile 4 from rotating, and the blocking element is used to be clamped between the deformation support ring 12 and the clamping ring wall 13 to deform under the action of the blocking element.
[0034] The inclination angle of the side wall of the deformable support ring 12 is 20° to 30°, and those skilled in the art can adjust the specific angle according to actual needs.
[0035] The bullet support block 2 includes a first blocking section 22 and a second blocking section 21, and the first blocking section 22 and the second blocking section 21 are both hollow cylindrical, one end of the first blocking section 22 is fixed to one end of the second blocking section 21 as a whole and the inside is connected, thereby ensuring that the projectile 4 can pass through the second blocking section 21 and the first blocking section 22 in sequence until the projectile 4 is ejected, the outer diameter of the first blocking section 22 is greater than the outer diameter of the second blocking section 21, and a step surface is formed at one end of the first blocking section 22 close to the second blocking section 21, and the step surface can The side wall of the bullet cartridge case 1 is limited, and the inner diameter of the first blocking section 22 is equal to the inner diameter of the second blocking section 21, so as to avoid jamming of the projectile 4 inside and affecting the firing of the projectile 4. The second blocking section 21 can extend between the inner wall of the deformable support ring 12 and the outer wall of the clamping ring wall 13 at the end away from the first blocking section 22, and drive the deformable support ring 12 and the clamping ring wall 13 to deform, and the side wall of the clamping ring wall 13 gradually deforms in the direction away from the outer surface of the projectile 4, and finally makes the clamping ring wall 13 separate from the outer surface of the projectile 4, so as to release the projectile 4.
[0036] The first blocking section 22 , the second blocking section 21 and the clamping ring wall 13 are all coaxially arranged to ensure smooth passage of the projectile 4 .
[0037] The outer diameter of the first blocking section 22 is equal to the outer diameter of the bullet cartridge case 1; the inner diameter of the second blocking section 21 is larger than the outer diameter of the support ring wall 13, thereby ensuring that the clamping ring wall 13 can enter the second blocking section 21, the outer diameter of the second blocking section 21 is smaller than the maximum inner diameter of the deformable support ring 12, and the outer diameter of the second blocking section 21 is larger than the minimum inner diameter of the deformable support ring 12, thereby ensuring that the second blocking section 21 can extend through the large end of the deformable support ring 12 and can drive the small end of the deformable support ring 12 to deform.
[0038] A plurality of annular grooves are provided on the outer wall of the bullet sabot 1, and a sealing ring 3 is embedded in each annular groove. The outer wall of the sealing ring 3 is used to fit the inner wall of the gun barrel 7. The sealing ring 3 is made of rubber material, and the outer wall of the bullet sabot 1 and the inner wall of the gun barrel 7 are sealed by the sealing ring 3, so that the bullet sabot 1 has good sealing performance, enhances the stability of the bullet sabot 1 and the projectile 4 in the gun barrel 7, makes this embodiment suitable for light gas gun firing, and improves shooting accuracy and reliability.
[0039] The bullet cartridge case 1 is made of resin material by 3D printing and has a certain elastic deformation, which can improve the elasticity of the deformation support ring 12 and enhance the stability of the system. The cartridge case stopper 2 is made of magnesium alloy material, which has good strength and lightweight characteristics. In the actual production process, technical personnel in this field can make adaptive changes to the above materials according to actual needs.
[0040] In order to ensure that the bullet buttress 1 and the projectile 4 do not interfere with each other when they are separated, it is necessary to optimize the structure of the bullet buttress 1 and make adjustments based on experimental results. For example, the angle between the deformation support ring 12 and the axis is adjusted to ensure that one end of the second blocking section 21 collides with the deformation support ring 12 first.
[0041] Through the above-mentioned design, this embodiment realizes the stable accelerated motion of the bullet butt 1 and the projectile 4 in the barrel, and realizes rapid and effective separation after leaving the barrel, thereby reducing the influence on the speed and trajectory of the projectile 4 and improving the accuracy of the experiment; moreover, this embodiment is reasonably designed and easy to operate, and does not require complicated operating steps to realize the rapid separation of the projectile 4 and the bullet butt 1, providing the user with a more convenient operating experience; on the other hand, by optimizing the design of the bullet butt 1, the motion trajectory of the projectile 4 in the experiment is made more stable, reducing the interference factors in the experimental process, and improving the repeatability and reliability of the experiment.

The bullet butt 1 and the projectile 4 are separated by a through hole 61, which is used to block the butt block 2. The through hole 61 can allow the projectile 4 to pass through. The diameter of the projectile 4 is slightly smaller than the aperture of the through hole 61. When the projectile 4 hits the target, the bullet butt 1 and the butt block 2 are blocked by the baffle 6. The barrel 7, the blocking limiter 5, the bullet butt 1, the butt block 2 and the through hole 61 are all coaxially arranged.
