내탄도 해석을 통한 추진제 형상설계 연구

초록

External and internal radii of the multi-perforated propellant configuration are major factors which have influences on performance of the gun system such as the muzzle velocity and the maximum breech pressure. According to the changes of the 7-perforated propellant configuration, in this study, a performance analysis has been conducted using the numerical code of the interior ballistics. As results, the muzzle velocity and the maximum pressure are confirmed as the function of external and internal radii. The relations among the external and internal radii, the maximum chamber pressure and the muzzle velocity have been obtained. Additionally, a basic design concept for the 7-perforated propellant has been provided.
