Abstract

The influence of impact of projectile on interior ballistic performance was studied, such as muzzle velocity, maximum press. A model for calculating resistance of the projectile was built based on characteristic of long free path of structure projectile-gun in this paper. The impact of the engraving process was taken into consideration, and according to two-phase flow interior ballistics theory, the interior ballistic performance was calculated. A test for interior ballistic performance was accomplished. The calculation results were in good agreement with test results. The studies show that muzzle velocity and maximum press decrease under impact of projectile.

Key words： interior ballistics; free path; impact; two-phase flow
