IDENTIFICATION OF THE DISTRIBUTION OF MUZZLE VELOCITY AND MAXIMUM PRESSURE IN THE BARREL FOR A TYPICAL RIFLE
The paper presents the procedure for identifying the distribution of muzzle velocity and the maximum pressure in the barrel for a typical 7.62mm rifle. Input data are collected through the experiment using 50 shots for muzzle velocity and 20 shots for maximum pressure. The distribution is identified with the support of Minitab software. Research results show three distributions suitable with muzzle velocity and maximum pressure in the barrel: the normal, 2P-Weibull and 3P-Weibull. Among them, the 3P-Weibull distribution is best suited to the muzzle velocity and the normal distribution is best suited to the maximum pressure in the barrel. The research results of the paper will help reduce the number of experiments when determining the muzzle velocity and the maximum pressure of the rifle.
