Supercritical carbon dioxide gas gun

Abstract

The invention discloses a supercritical carbon dioxide gas gun. The supercritical carbon dioxide gas gun is applicable to occasions such as earthquake relief and fire extinguishing rescue. The supercritical carbon dioxide gas gun consists of a gun carriage and a gun body, wherein the gun body is composed of a carbon dioxide high-pressure gas chamber, a magnesium powder heating pipe, a diaphragm, atransition section, a gun barrel and a shell; and the gun carriage is composed of walking wheels, a frame, a direction steering device and the like. The energy of the gas gun is from the exothermic reaction of magnesium powder and carbon dioxide under the heating condition, magnesium oxide and carbon are generated and a large amount of heat is released in the reaction, the unreacted carbon dioxide absorbs the heat, the pressure is rapidly increased, and then the diaphragm is broken to push the shell. The supercritical carbon dioxide gas gun is simple in structure, convenient to machine, simple to install and better in safety compared with a traditional gun, is suitable for meeting various non-combat requirements including obstacle breaking and enemy expelling, and has wide application prospects in various situations such as rescue and disaster relief, army safeguard stability and army marching.

Description

technical field [0001] The invention belongs to the technical field of fluid application, and relates to a structure of a supercritical carbon dioxide gas cannon, specifically, a carbon dioxide gas cannon that uses supercritical carbon dioxide as a working medium to expand and do work to launch projectiles. Background technique [0002] A gas cannon is a launch system that uses the expansion of a gas medium to do work to push the projectile to move at high speed. It has the ability to launch projectiles at high speed, and its shock loading can generate strong shock wave pressure in solid materials. Although compared with conventional artillery, gas cannon is less powerful, but it has some advantages that cannot be replaced by conventional artillery: (1) Compressed gas cannon has strong versatility, can launch various types of ammunition, and can achieve multiple purposes: In the task of passing through and ensuring the passage, it can launch kinetic energy gravel bombs to qu...

AI Technical Summary

Problems solved by technology

[0004] In view of the above defects and deficiencies existing in the existing gas cannon, the object of the present invention is to provide a supercritical carbon dioxide gas cannon, which uses supercritical carbon dioxide as a working medium to expand and do work to push the projectile to move. Supercritical carbon dioxide has high energy density, gas Inactive, no flammable and explosive problems, and environmentally friendly, no pollution or irritating gases, etc., so that the supercritical carbon dioxide gas cannon of the present invention does not contain any flammable and explosive substances, safe and effective, and dismantling It is suitable for various non-combat forms of breaking obstacles and repelling enemies, and has broad application prospects in various situations such as emergency rescue and disaster relief, maintaining stability of troops, and marching troops.
