초록

본 논문에서는 한국형발사체 2, 3단을 수정하여 500 kg 급 차세대 중형위성(CAS500)을 지구 저궤도(LEO)에 단독 발사할 수 있는 2단형 소형발사체를 설계하였다. 한국형발사체는 3단 발사체이므로 소형발사체로의 활용을 위해서는 단별 속도증분이 새롭게 분배되어야 한다. 이를 위하여 설계 변수로는 단 질량비, 구조비와 1, 2단 엔진 옵션을 고려하였으며, 이에 대한 단 설계 및 궤적해석을 수행하였다. 결과 검토로부터 500 kg 급 위성의 LEO 단독 발사가 가능한 소형발사체 설계변수의 조합을 확인하였다.

In this paper, design study of a small two-stage launch vehicle is undertaken for the dedicated launch of the Compact Advanced Satellite 500 (CAS500)-class satellite into the Low Earth Orbit (LEO) by modifying the second and third stages of the Korean Space Launch Vehicle II (KSLV-II). Since the KSLV-II has three stages, velocity increment is newly distributed for the two-stage small launch vehicle. For this end, the staging design is carried out for the design parameters such as stage mass ratios, structural coefficients and engine options for each stage followed by trajectory analysis. Investigation of the results provides the combination of design parameters for the small launch vehicle for the dedicated launch of 500 kg-class satellite into LEO.
