Cannon body structure of a supercritical carbon dioxide gas cannon

Abstract

The invention provides a cannon body structure of a supercritical carbon dioxide gas cannon, which is used for emergency rescue in earthquake relief, emergency rescue and other occasions. The magnesium powder in the heating tube is ignited by electric sparks and releases a large amount of heat, which makes the temperature and pressure of the carbon dioxide in the liquid filling tube rise sharply and quickly reach a supercritical state. When the pressure exceeds the rupture limit of the rupture disc, a rapid jet of carbon dioxide pushes the projectile. Wherein the acceleration connection section in the present invention is composed of an acceleration section and a recoil section, which significantly improves the exit velocity of the projectile, and at the same time significantly reduces the barrel length. The invention has the advantages of simple structure, safety and reliability, fast filling, portability and high efficiency, and is suitable for emergency rescue.

Description

technical field [0001] The invention relates to a gas cannon, more specifically, a cannon body structure of a supercritical carbon dioxide gas cannon. Background technique [0002] In occasions such as earthquake relief and emergency rescue, blasting equipment with long operating distance, high safety and stability, and good portability is required. However, traditional artillery is destructive, dangerous, and low in maneuverability, so it is not suitable for emergency rescue. The gas cannon is a device that uses the principle of aerodynamics, uses compressed gas as the working medium, and uses a differential pressure device and a quick exhaust valve that can realize automatic control to instantly convert the gas pressure energy into the kinetic energy of the air jet and generate a strong impact. The gas cannon has the ability to launch projectiles at high speed, and its shock loading can generate a shock wave pressure of hundreds of MPa to hundreds of GPa in solid material...

AI Technical Summary

Problems solved by technology

However, the gas cannons of existing light gas are highly dangerous due to the gas, and the energy consumption is large when compressing the gas, and the structural design characteristics of the existing gas cannons cause them to have relatively large recoil, and the length of the barrel is relatively long , and requires a large amount of ammunition, the safety needs to be further improved, the cost is relatively high, and the loading speed is relatively slow, and there are many auxiliary equipment, which is difficult to carry, which affects the popularization and application of gas cannons
