The Influence of Loaded Conditions on the Interior Ballistic Performance

Abstract

This paper mainly studies the change rules of interior ballistic performance under different loaded conditions, especially the maximum pressure and the muzzle velocity. There are six parameters affect the performance. The results show that, changing one of the all parameters, the maximum pressure and velocity will be increased with the increase of propellant shape coefficient χ; increased with the charge increases; increased as the propellant force increases; decreased with the chamber volume becoming bigger; increased with the engraving pressure increases; the maximum pressure increases while the velocity decreases with the mass of the projectile increases. In order to improve the interior ballistic performance, these loaded conditions must be paid attention.
