Problems solved by technology

[0007] In order to solve the problem that the flaps of the existing petal-shaped cracked bullet holder cannot be closely matched and integrally sealed, the stability of the accelerated movement of the bullet holder and the bullet in the chamber is affected; and when the bullet holder is separated, the flaps are easy to interfere with each other, resulting To solve the problem of the impact of the separation of the support on the velocity of the projectile, a kind of support for the pneumatic separation of the projectile through the muzzle cutter is provided

specific Embodiment approach 1

[0016] Specific implementation mode one: combine Figure 1 to Figure 5 Describe this embodiment, a bullet holder that realizes pneumatic separation through a muzzle cutter, which includes an upper petal 1, a lower petal 2 and two sealing rings 3, and the upper petal 1 and the lower petal 2 are cut along the symmetrical plane by the same rotating body Formed, a plurality of muzzle cutters 6 are installed on the outer surface of the outlet direction in the gun bore, and the outer surface after the upper lobe 1 and the lower lobe 2 are matched is the first gradually expanding cone section 10-1, the first gradually expanding cone section 10-1, and the second A columnar section 10-2, tapered cone section 10-3, second columnar section 10-4, second tapered section 10-5 and third columnar section 10-6; upper lobe 1 and lower lobe 2 On the first gradually expanding cone section 10-1, rely on the involute arc teeth to cooperate; the upper petal 1 and the lower petal 2 are coated with a ...

specific Embodiment approach 2

[0019] Specific implementation mode two: combination Figure 3 to Figure 5 Describe this embodiment, each muzzle cutter 6 in a plurality of muzzle cutters 6 of this embodiment all comprises cutting blade frame 6-1 and cutting blade 6-2, and cutting blade frame 6-1 is installed on On the outer sidewall of the gun bore, the cutting blade 6-2 is installed on the lower end of the cutting tool holder 6-1, and the lower edge of the cutting blade 6-2 stretches out toward the gun bore inner cavity. When the bullet holder moves forward at high speed, the inner surface of the variable diameter reaming hole 10-5-2 is affected by the high-pressure pneumatic force; when the bullet holder is out of the chamber, the two sealing rings 3 on the bullet holder are cut sequentially by the muzzle cutter 6, as image 3 Shown; Wherein the cutting blade 6-2 lower edge protrudes into the gun bore less than the gap between the bullet holder and the gun chamber, and the cutting blade 6-2 does not contac...

specific Embodiment approach 3

[0020] Specific implementation mode three: combination Figure 3 to Figure 5Describe this embodiment, the cutting blade 6-2 of this embodiment is a triangular cutting piece, and the cutting edge of the cutting blade 6-2 faces the cavity exit direction of the upper lobe 1 and the lower lobe 2. Such setting is convenient to ensure that the blade faces the sealing ring and cuts the sealing ring just in time. Other compositions and connections are the same as those in the second embodiment.

Abstract

The invention discloses a sabot capable of realizing pneumatic separation through muzzle cutters, and relates to a sabot. By adopting the sabot disclosed by the invention, the problems of a current segmented fractured sabot that close match and integral sealing cannot be realized among segments, so that the stability of accelerated movement of the sabot and a bullet in a bore is affected; and interference can easily occur among the segments during separation of the sabot, so that the speed of the bullet is affected by separation of the sabot are solved. According to the sabot, the upper and lower segments of the sabot are formed by cutting the same rotary body along a symmetrical surface, and the two segments are matched with each other at a tail part divergent conic section through divergent arc teeth; matched surfaces of the upper segment and the lower segment are separately coated with a thin layer of rubber; the front and rear cylindrical sections of the sabot are separately provided with an annular groove; after the upper segment is matched with the lower segment, the two annular grooves are separately provided with a sealing ring, so that the sabot can be arranged in the bore in a slidable manner; the multiple muzzle cutters are arranged on the outer surface of the bore in the outlet direction; and the sealing rings are cut when the sabot leaves the bore, so that pneumatic separation is realized after the sabot leaves the bore. The sabot disclosed by the invention is applicable to the experiment of shooting a subcaliber bullet with a light-gas gun.

Description

technical field [0001] The invention relates to a bullet holder, in particular to a bullet holder in an experimental device for launching a subcaliber high-speed supercavitation projectile by using a light gas gun. Background technique [0002] The light gas gun is a device that uses the high-pressure air chamber at the rear end of the chamber to supply air to the chamber and push the projectile to accelerate in the chamber so that it can obtain a certain speed out of the chamber. It is currently widely used in various projectile launches and projectile collisions. Damage experiment. In order to obtain a higher exit velocity for the projectile, in addition to increasing the pressure of the air chamber and the length of the chamber, it is also a convenient and effective means to expand the diameter of the chamber and use the bullet holder to adapt to launch sub-caliber projectiles. [0003] When using a bullet holder to adapt to launch a sub-caliber projectile through a ligh...
