Recently, more and more researchers have shown interest in studying the temperature gradient of unconventional shots, including shots with a travelling charge. The paper considers the possibility of taking into account the effect of the initial charge temperature, in particular, on the travelling charge from the pasty propellant, in the form of a linear relationship, through the use of a mathematical tool for qualitative analysis of experimental data. A study was made of taking into account the influence of the temperature coefficient in one or several parameters characterizing the propellant combustion on the ballistic characteristics of the shot. It is shown that for pasty propellants, taking into account the temperature coefficient in the travelling charge dispersion rate and the layer-by-layer burning rate of dispersed propellant particles, as well as the dependence of the transition pulse to the accelerated TC burning mode on the initial charge temperature, provides good agreement on the shapes of pressure variation curves in the loading chamber and velocity projectile in the barrel.
