A sub-caliber projectile launch and separation device

Abstract

The invention discloses a subcaliber shot launching and separating device. The subcaliber shot launching and separating device comprises a shot support for supporting and launching shots, and a separation device, wherein the shot support is provided with two different structures including an I type shot support body and an II type shot support body, and the separation device is used for separatingthe shot support. One end of a guiding device is arranged on a gun barrel, and a guiding hole consistent to a gun barrel inner hole in size and smooth finish, a releasing hole with the large diameter, and four air releasing holes with the fan-shaped cross sections are included. The separation device is arranged at the other end of the guiding device and provided with a cone boss and a launching hole allowing the shots to pass. The guiding hole and the releasing hole of the guiding device, the launching hole of the separation device and the barrel pipe inner diameter are coaxially arranged. Bymeans of the subcaliber shot launching and separating device, the subcaliber shots can be smoothly launched and stably separated from the shot support, and the situations of obvious shot rotation, rotation speed losses and the like are avoided.

Description

technical field [0001] The invention belongs to the technical field of launching projectiles of single-stage light gas cannons, and in particular relates to a launching and separating device for subcaliber projectiles. Background technique [0002] Single-stage light gas gun is a commonly used test equipment in high-speed collision dynamics. By suddenly releasing the propellant (air, helium or hydrogen, etc.) injected into the gas chamber, the projectile can be accelerated to a maximum speed of 1km / s around the speed. In different high-speed collision experiments, the diameter of the projectiles studied varies widely, and the number of single-stage light gas barrels of different sizes is limited, so the sub-caliber projectile launch and separation device is an indispensable structure. [0003] At present, non-metallic bullet rests are generally used as a support to launch sub-caliber projectiles. The bullet rest materials are rigid polyurethane foam, nylon and plexiglass, ...

AI Technical Summary

Problems solved by technology

However, the existing separation devices of this type are more concerned with the launch of the secondary light gas cannon, that is, the separation of the projectile and the bullet holder under ultra-high-speed impact. Therefore, the overall separation device has a complex structure and is difficult to install. At the same time, some structures After firing once, it needs to be replaced due to damage. This kind of scheme design is obviously not suitable for single-stage light gas guns with low firing speed.
