Abstract

안전분리 비행시험에서 사진계측 기법을 이용하여 분리되는 외부장착물의 분리특성을 분석하였다. 한 대의 카메라를 사용하여 6자유도를 해석할 수 있는 기법을 적용하였으며, 사진계측의 이론적인 배경과 MIL-HDBK-1763에서 제시하는 내용을 토대로 계측 요구조건을 정립하고 비행시험에 적용하여 분리궤적을 추출하였다. 사진계측의 오차에 영향을 주는 입력변수들의 불확실성을 경험에 의해 추정하였으며, 각각의 입력변수들에 의한 궤적오차를 고려하여 분리안전성을 분석하였다. Photogrammetric techniques were used to analyze separation characteristics of store in safe separation flight test. In this analysis, we used single camera method to analyze 6 degrees of freedom of separated store. We established instrumentation requirements based on theoretical background of photogrammetry and guidelines of MIL-HDBK-1763. We applied the photogrammetry to flight test and extracted separation trajectory. We empirically estimated the input variables uncertainties of photogrammetry and its effects on separation trajectory. Using this trajectory which includes the photogrammetric error, we analyzed the safety of separation.
