초록

운동에너지 막대 탄두 시스템은 기존 시스템의 장점을 결합한 새로운 형태의 요격탄두 시스템으로서 직격 파괴방식에 비해 표적 유도 정밀도에 대한 의존도가 낮을뿐더러, 고폭 파편 탄두 방식보다 더 높은 관통력을 제공해 준다는 장점이 있다. 본 논문에서는 다양한 운동에너지 탄두의 사출 방식 중 등방성운동에너지 탄두의 기폭, 전개모델을 소개하고, TATE 관통방정식을 이용하여 사출된 관통자의 관통 효과를 계산하였다. 또한 교전 성능 분석을 위한 방법을 제시하였으며, 다양한 교전 상황에 대한 몬테-칼로 시뮬레이션을 통해 최적의 교전 기하 및 기폭 시점을 도출하였다.

Kinetic energy(KE) rod warhead system is a new interceptor which combines advantages of existing ones. This system is less dependant on a precision guidance than direct hit type warhead and gives high penetration rates than blast fragmentation type warhead. In this paper, isotropic KE rod warhead system is introduced with detonation/deployment model. A penetration effects of the deployed rods are calculated using TATE penetration equation. Also, an engagement performance analysis method is suggested. Finally, an optimal detonation time and engagement geometry is derived by Monte-Carlo simulation in various engagement situation using the performance analysis factor.
