Abstract

At the stage conceptual design, combat vehicle is classified into three general categories of fire power, mobility and physical properties of system. The present research is restricted to fire power and its optimization. At the stage of conceptual designing of system, it is appropriate to consider major variables affecting fire power - including the weight of bullet, which exerts a direct influence on destroying effect, maximum range which takes long range firing in consideration. To estimate the maximum firing range, a simple interior ballistic and an exterior ballistic model were built by using the lumped parameter method, Le Duc method and point mass trajectory model. Design of experiment and regression analysis was used to derive simulations of fire power. Finally, response surface models were built and design variables were analyzed.

개념설계단계에서 전투차량은 크게 화력성능, 기동성능과 체계의 물리적 특성으로 나누어진다. 본 연구에서는 전투차량체계를 구성하는 3가지 특성 중 화력성능의 최적화로 제한한다. 체계의 개념설계 단계에서 화력성능에 영향을 미치는 주요 인자로 파괴효과에 직접적인 영향을 주는 탄의 중량과 원거리 사격을 고려한 최대사거리를 분석대상으로 선정하였다. 최대 사거리 분석을 위하여 강내탄도와 강외탄도해석은 질량 집중 모델, Le Duc모델과 질점탄도모델을 사용하여 분석하였다. 실험계획법과 회귀분석으로 반응표면식을 구성하고 선정된 인자를 반응표면법으로 최적화하였다.
