Estimation of ultimate capability of a shot with use high-density propellants for an increase in projectile muzzle velocity

Theoretical studies aimed at demonstrating efficiency of using high-density high-energy propellants in an artillery round are carried out. Parametric studies on shot capabilities are performed using the special software package based on a mathematical model of intraballistic processes. The shot is fired using a model high-density propellant with a traveling charge placed in the bore behind the shell in addition to the main propellant charge in a medium-caliber model ballistic setup. The propellant burning law obtained by calculations and experiments on a small-caliber setup is adapted to a medium-caliber one. Charging conditions are determined to achieve the highest increase in the projectile muzzle velocity with the use of propellants as compared with a classical charging scheme of the shot at a maintained level of the required pressure. Recommendations for upgrading high-density propellants resulting in an additional increase in the projectile muzzle velocity are presented.
