“…In particular, the automatic firing system using combustible gas energy is mainly used. Based on the principle of using the energy of the combustible gas, the automatic firing system of the weapon is divided into three types: The automatic firing system works on the principle of blow-back weapons, the automatic firing system works on the principle of the recoil -operated weapons and the automatic firing system works on the principle of gas-operated, [1][2][3][4][5][6][7][8][9][10][11]. Automatic weapons operating on the principle of gas-operated are commonly used because it has a simple structure, the structure of the air chamber is capable of adjusting the level of effect of the combustible gas on the piston.…”

This paper mentions a new approach to accurately and fully describe the mathematical model of the automatic firing system of gas-operated machine guns. The mathematical model is established based on Lagrange's equations of the second kind. A numerical method was used to solve the research problem. The automatic firing system of the PKMS machine gun (of Russian origin) was selected for calculation and testing. After the research model is calculated, a comparison is made between the theoretical calculation results and the experimental results to verify the mathematical model. The comparison results between the calculation from the theoretical model and the results obtained from the experiment show that the mathematical model is suitable and reliable, the maximum velocity error of the bolt carrier is only 6.53%. The results obtained from this study are the basis for evaluating the working ability of the automatic firing system. This is also a reliable theoretical basis for designers to optimize the structure for automatic firing systems of gas-operated automatic weapons.
