To the question of the influence of ambient temperature for the shooting process

Abstract

In this article, an assessment is made of the influence of air temperature on the processes
occurring during a shot. The analysis of the results of practical firing from the ZU-23 twin anti-
aircraft artillery mount was carried out. According to the developed methodology using the methods
of planning the experiment, a study was conducted taking into account two factors. Statistical
analysis methods were used to process the experimental data using MS Excel. As a result of
processing the data of the experimental study, an approximating function was determined that
describes the dependence of the initial velocity of the projectile on the wear of the bore and the
temperature of the powder charge.
It has been established that the approximating function is statistically reliable, adequate, and
allows predicting the change in the initial velocity of the projectile. The calculation of the degree of
influence of these factors on the ballistic characteristics of the gun is made using standardized
coefficients. The ways of increasing the efficiency of firing artillery pieces are proposed.
