초록

본 논문은 시험발사체의 비행궤적 및 낙하점 분산 분석에 대해 다룬다. 2018년 11월의 시험발사체 비행시험 전/후에 수행한 비행궤적 및 낙하점 분산 분석 과정을 설명하고 비행시험 결과와의 비교를 통해 분산 분석 방안이 적절하였음을 보인다. 발사체의 궤적 및 낙하점 분산은 발사체 성능 오차 요인 및 대기권에서의 바람 영향을 고려한 6자유도 몬테카를로 시뮬레이션을 통해 이루어진다. 이와 같이 사전에 분석한 결과를 토대로 비행시험 전에 낙하 안전 영역을 설정한다. 결과적으로, 시험발사체는 사전에 분석한 궤적 및 낙하점 분산 범위 내에서 안전하게 비행하였다.

This paper considers the trajectory and impact point dispersion analysis of the test launch vehicle (TLV). The analysis, which performed before and after its flight test on November 28, 2018, is described and verified by comparing with the flight test results. The six degree-offreedom (DOF) simulation is used to compute the dispersion of the trajectory, attitude, and impact point, where the launch vehicle performance variations and wind effects during the atmospheric phase are included. The impact area to guarantee the flight safety is determined using the results of the dispersion analysis. The flight test results confirm that the safe flight of TLV is performed within the predicted dispersion boundary.
