Abstract

This paper addresses Monte-Carlo simulation analyses for the stage separation of the general launch vehicle. The stage separation event of the launch vehicle occurs during a very short time and is related with many dynamic parameters. The stage separation is a critical event in that the launch fails if there is a collision during the stage separation. The stage separation analyses was conducted for the general launch vehicle to confirm the separation without collision within the designed clearance in case of the random input parameters. This paper presents the stochastic results of the stage separation of the launch vehicle using the Monte-Carlo simulation.

본 논문에서는 일반적인 발사체의 형상에 대하여 몬테카를로 시뮬레이션을 적용하여 분리 유격 분석을 수행하였다. 단 분리는 매우 짧은 시간동안 이루어지며, 매우 많은 운동 변수가 관계되고 충돌 발생시 발사 실패가 나타나는 매우 중요한 비행 이벤트이다. 다양한 오차요인이 무작위(random)로 발생하는 경우에도 설정된 유격조건 내에서 분리가 됨을 확인하기 위해 일반적인 발사체 형상에 대한 단 분리 분석을 수행하였다. 몬테카를로 분석 기법을 발사체 단 분리 분석에 적용함으로서 단 분리 운동시 확률적인 결과들을 제시하였다.
