Temperature conditions influence on the change in the initial velocity of the 6.5mm grendel projectile

Abstract

In this paper, the experimental method and mathematical procedure of measuring the 6.5 mm Grendel projectile's initial velocity at different temperatures, were analyzed. A mathematical model of external ballistics has been defined, that is, a mathematical calculation of the projectile's initial velocity has been made for the given conditions. The aim was to perform a comparative analysis at different temperatures based on the obtained results (analysis of the experiment and the mathematical model of external ballistics). The goal of this paper was to determine, based on experimental testing and mathematical calculations, whether the gunpowder for the Grendel 6.5 mm projectile is thermostable.
