Novel projectile holder

Abstract

The invention relates to the technical field of ballistic tests, in particular to a novel projectile holder. The novel projectile holder comprises a shell and a hollow gas closing ring; a containing groove used for containing a projectile body is formed in one end of the shell, a conical bottom pusher is arranged at the other end of the shell, a wind resistance slope is arranged at an opening of the containing groove, curved slits are arranged on the side wall of the shell, and the slits extend in the length direction of the shell; one end of the gas closing ring is detachably connected with a tail cone, a tail skirt expanding outwards is arranged at the other end of the gas closing ring, a projectile holder bottom concave part is formed between the inner wall of the tail skirt and the conical bottom pusher, and a through hole is formed in the side wall of the gas closing ring. The curved slits can prevent and delay gas in a gun barrel from penetrating through the slits and entering the containing groove, and therefore a good gas closing effect is achieved, the projectile holder and the projectile body move together in the gun barrel, and the speed of the projectile holder is controlled; and through the application of multiple technical means, the projectile holder can be finally stably launched at a controllable speed, a stable target hitting posture is achieved during projectile body target hitting, and an expected experimental result is achieved.

Description

technical field [0001] The invention relates to the technical field of ballistic testing, in particular to a novel bullet holder. Background technique [0002] It is a key technology in projectile test research to load the projectile to high speed to achieve high-speed impact on the target. Commonly used loading methods include two-stage light gas guns, ballistic guns, etc. The projectile body is loaded by the high-pressure gas force at the bottom in the chamber. The bullet holder is an important part to realize loading. Its main function is to Drive and guide the movement of the projectile to achieve a higher speed and at the same time ensure that the projectile does not deflect in the bore, avoid the occurrence of phenomena such as slashing, and at the same time ensure that the projectile maintains a good flight attitude in the initial stage after it is released from the chamber, improving the experimental performance. effectiveness. [0003] At present, an integrated bo...
