A device for separating projectile and projectile support

Abstract

The invention discloses a device for separating a bullet and a bullet support, which comprises a guide chamber and a separating chamber which are arranged on the outlet of a gun barrel. The guide chamber and the separating chamber are respectively provided with an elliptical air release hole; the guide chamber is connected with support plates; a separating block, a buffering plate and a stopping block are arranged in the cavity of the separating chamber; one end of the separating block is conical; the mouth of the separating block is in a horn shape; the other end of the separating block is cylindrical, and a variable-diameter centre hole penetrates through the cylindrical end of the separating block; the cylindrical end of the separating block is positioned by a boss in the separating chamber; the buffering plate is arranged between the cylindrical end of the separating block and the boss in the separating chamber; the mounting position of the conical end of the separating block faces to the gun barrel; the stopping block is of a stepped cylindrical structure with a centre hole; the stopping block is located at the bottom part of the separating chamber and is positioned by the boss in the separating chamber; and the centre hole of the separating block and the centre hole of the stopping block are coaxially arranged. The device for separating the bullet and the bullet support is capable of effectively preventing fragments generated in the impact process from impacting a target plate together with a bullet.

Description

technical field [0001] The invention relates to a separating device, in particular to a projectile carrier separating device used for an ultra-high-speed projectile launching device. Background technique [0002] The research on the ultra-high-speed impact process is of great significance to scientific and technological fields such as astrophysics, geophysics, artificial satellite protection, and tactical weapon interception. The two-stage light gas gun has become one of the main means of launching ultra-high-speed projectiles because of its wide adaptability to the shape, quality, material and speed of projectiles. In the test, in order to prevent the high-speed motion of the metal projectile in the launch tube from causing serious damage to the launch tube, it is necessary to use plastic to make the bullet holder, which contains the projectile to be launched. When launching, the plastic bullet holder directly contacts and rubs against the launch tube. After exiting the mu...

AI Technical Summary

Problems solved by technology

However, the cone-shaped interceptor cannot intercept the part of the shell that is cut off from the back of the projectile; the deformation and collapse of the cone during the impact process will also cause a part of the debris to hit the target plate

Secondly, after the projectile and the bullet rest are separated, the entire interceptor will be separated from the muzzle and fly forward. A large mass blocking plate must be placed in front of it, making the overall structure complex, and the tapered mouth interceptor is not compatible with the muzzle and the interceptor. The components of the interceptor are all bonded and connected with 502 glue, the connection strength is low, and the entire interceptor can only be used once

Finally, it has not been reported whether the projectile with heavier weight and larger geometric size can be successfully separated
