Cold launching method of artillery shell

Abstract

The invention relates to a cold firing method of an artillery shell. The cold firing method is different from a traditional artillery in components such as a gun barrel (1) and an artillery shell (10), and is additionally provided with a gas storage tank (8). The artillery shell (10) is not provided with a gun barrel and does not need to launch gunpowder; the artillery shell (10) is cold-launched, so that high temperature and ablation caused by detonation of gunpowder launched by the traditional artillery are thoroughly eliminated, the service life of the gun barrel (1) is prolonged, and the manufacturing difficulty of the gun barrel (1) is reduced; the firing range of the artillery shell (10) or the mass of the artillery shell (10) can be increased only by increasing the structural strength of the component and increasing the pressure intensity of the compressed air; and when the artillery shell (10) is launched, no flame or smoke exists, the concealment is good, and the war damage rate is low. Molecular potential energy of the compressed air is converted into kinetic energy of the artillery shell (10), chemical energy of traditional gun fuel is replaced and converted into kinetic energy of the artillery shell, and environment friendliness is achieved; and the replacement of a cold weapon by a hot weapon is a technical progress, and the replacement of the hot weapon by the cold weapon is not backward, but is a greater progress, so that far-reaching influence may be generated.

Description

technical field [0001] The invention relates to a method for cold launching of shells, in particular to a method for cold launching of shells without gunpowder. Background technique [0002] The current cannon has the following defects. [0003] First, the range of the projectile does not exceed 100 kilometers, and it is very difficult to increase the range. [0004] Second, the barrel is difficult to manufacture. [0005] The barrel has very high requirements on steel. The development of a new gun barrel steel will cost huge sums of money and repeated trials. It will take more than ten or twenty years at every turn, and the cost is extremely high. [0006] In the process of manufacturing the barrel, it needs to go through forging, drilling, elongation, forging, heat treatment, straightening, peeling off the oxide layer, self-tightening, parallel drawing, cutting inside the tube, processing rifling, etc., which is very cumbersome and complicated. [0007] Its three, barr...

Problems solved by technology

[0009] The causes of the above defects are high temperature, high pressure and ablation during the deflagration of the propellant powder, as well as the friction of the projectile
