Rapid fire weapon barrel anti-ablation wear test method and device

Abstract

The invention provides an experiment method and device for ablation and abrasion resistance of rapid-fire weapon barrels. The method comprises the steps that 1) an experiment device is prepared, wherein the device comprises a pipe, an explosion shock explosive box or an explosive feeding port, a heating device and a high-pressure gas device; 2) the rapid-fire weapon barrels are connected to the two ends of the pipe respectively, and inner cavities are communicated with an inner cavity of the pipe separately to form a sealed gas channel; the rapid-fire weapon barrels and the heating device arecooperatively installed; 3) explosion shock explosive is heated or ignited, and a burning compound is obtained through burning; 4) high-pressure gas and the burning compound enter the inner cavities of the rapid-fire weapon barrels; 5) the rapid-fire weapon barrels are heated and cooled to obtain the rapid-fire weapon barrels. According to the method, from three aspects of the temperature, atmosphere and abrasion, the real environment where bullets or cannonballs penetrate through the barrels is simulated, the accuracy of a detection result is improved, the detection work is simplified, and the working efficiency is high; the experiment cost is lowered, the labor amount is greatly lowered, and the labor cost is reduced.

Description

technical field [0001] The invention relates to an experimental method and device for testing the barrel performance of a rapid-fire weapon, in particular to a barrel thermal ablation wear performance testing device. Background technique [0002] In the research on improving the life of weapons, the research on the life of the barrel has always played an important role, especially the research on the life of the barrel of the large-caliber machine gun and the barrel of the shell is more important. During the shooting process, the inner bore of the barrel bears the high temperature, high pressure, scouring and chemical corrosion of the gunpowder gas in a short period of time, and at the same time resists the extrusion and wear of the projectile guide side. The working environment is very harsh. Under such complex working conditions, after a certain number of shooting cycles, the inner bore of the barrel will gradually be damaged. It is seriously affected, and in severe cases...

AI Technical Summary

Problems solved by technology

After the ablation is serious, the tube will have negative conditions such as thermal stress and thermal bending, which will directly cause the pressure drop in the barrel bore, the initial velocity of the shell, and the shooting accuracy to drop. request, the barrel will be scrapped

In addition, the spiral flight of the bullet in the high temperature and high pressure barrel will definitely have a strong impact and wear on the barrel, which will further accelerate the damage of the barrel

The high temperature, high pressure and impact wear caused by bullets shuttled through the barrel make it extremely difficult to evaluate and detect the life of the barrel. At present, there is no testing and inspection equipment in this area in China. In engineering, we can only rely on the handle to test the life of the gun. In the experimental research, the life of the barrel is mainly evaluated by two sets of experimental methods, ablation and wear, which not only cause a lot of waste of bullets and shells, but also make it difficult to guarantee the accuracy of the experimental results under the same conditions.
