Air-float piston type launcher

Abstract

The invention discloses an air-float piston type launcher, which is used for solving the technical problem of complex structure of the traditional launcher. The technical scheme of the air-float piston type launcher is that: an air-float piston structure is adopted, air is used for floating a piston to work by utilizing pressure difference at two sides of the air-float piston, so that the structure of the launcher is simpler. The air-float piston moves at a high speed, is flexible to operate and has high reliability, and the problem of kinetic resistance of the piston is avoided. During launching, the air-float piston moves quickly, the initial opening capacity of high-pressure gas entering a gun tube is large, and the fact that the high-pressure gas enters the gun tube to push a shot body or birdshot is a constant-pressure constant-acceleration process.

Description

technical field [0001] The invention relates to a launching device, in particular to an air-floating piston type launching device. Background technique [0002] refer to figure 2 , Document 1 "A primary light gas gun for material collision experiments, explosion and impact [J], 13 (1) (1993) 90-96" discloses a primary light gas gun device for launching projectiles, the device Including air chamber 1, rear diaphragm 2, pilot valve 3, front diaphragm 4, projectile 5, barrel 6, fragment chamber 7. The rear diaphragm 2 and the front diaphragm 4 are sealed with the inner wall of the fragment chamber 7 . When launching the projectile 5, first inject the preset pressure p into the air chamber 1, then open the pilot valve 3, the pressure between the rear diaphragm 2 and the front diaphragm 4 will decrease rapidly, and the pressure difference between the two sides of the rear diaphragm 2 will decrease with the When it increases to a certain value, the rear diaphragm 2 ruptures, an...
