Abstract

Aircraft combat survivability analysis is essential process for the development of combat aircraft. M&S methodology is the typical procedure for the aircraft combat survivability analysis, and the last step is the expensive Live Fire Test if it is necessary. This study introduced cost and time effective survivability analysis methodology based on the random variable weighted score algorithm in conceptual design phase. For this study, essential element and event analysis (E3A) is used to define the random variables and Monte-Carlo simulation is implemented to estimate weighted score and the final value of survivability.

군용 항공기의 개발과정 중 전투 생존성 분석은 반드시 거쳐야 할 필수 과정이다. 군용 항공기의 전투 생존성 분석을 위한 방법은 M&S 기법 적용이 일반적이며 필요시 최종단계에서 Live Fire Test를 거친다. 본 연구에서는 비용대비 효과도를 고려하여 M&S기법을 통해 개념설계단계에서 신속하게 정성적으로 전투 생존성을 분석할 수 있는 연구를 수행하였다. 본 연구를 위하여 필수사건 및 필수요소 분석기법, 몬테카를로 시뮬레이션 등 확률, 통계기법들을 이용한 '확률변수 가중치 환산법' 알고리즘을 고안하여 제시하였다.
