Abstract
본 논문에서는 나로호 발사체의 1차 비행시험에서 얻은 데이터를 바탕으로 발사체의 비행시험에서의 궤적 및 성능, 자세 제어에 대한 분석을 수행하였다. 나로호의 1차 비행 시험에서는 페어링의 비정상 분리 문제가 발생하였으며, 이에 따라 위성의 궤도 투입이 실패하였다. 본 논문에서는 이러한 페어링 비정상 문제를 고려하여, 궤적 및 비행 성능, 자세제어 특성을 분석하였다. 또한 관성항법유도시스템의 비행 결과 및 성능 분석도 제시되었다. 비행후 분석 결과 페어링 분리 문제 이외에 다른 문제는 발생하지 않았으며, 다른 탑재 시스템들이 정상적으로 작동하였다. This paper presents the analysis results of trajectory, performance and attitude control based on the first flight data of the KSLV-I. The KSLV-I had a fairing separation problem and failed to inject spacecraft into the orbit. In this paper, the trajectory, flight performance, and attitude control was analyzed considering the influence of unseparated fairing. Moreover, the flight results and performance of the inertial navigation and guidance system were presented. As a results of post-flight analysis, any other problem besides the fairing separation problem was not happened and onboard equipment functioned normally.
