Abstract

This paper introduces the result of the conceptual design of a ground-launched small launch vehicle system aimed at inserting a 500 kg small satellite into a sun-synchronous orbit at an altitude of 500 km. The launch site is set to use the first launch site of the Naro Space Center or a public launch site in the space industry cluster to be built with government support in the future, and the first stage engine is set to use a 75 tonf engine used in the second stage of the Korean Space Launch Vehicle-II, and the second stage engine is set to use a high performance 3 tonf class methane engine developed through the Small Launch Vehicle Development Capability Support Project of the Ministry of Science and ICT. System engineering techniques were applied to the design process, from concept of operations analysis to requirements analysis, launch vehicle staging design and configuration design (sizing and layout design), and mission analysis.

본 논문은 500 kg 급 소형위성을 고도 500 km의 태양동기궤도에 투입하는 것을 목표로 하는 지상발사 소형발사체 체계에 대한 개념설계 결과를 소개한다. 발사장은 나로우주센터의 제1발사장 또는 향후 정부 지원으로 구축될 우주산업 클러스터의 민간발사장을 활용하는 것으로 설정하였고, 발사체 1단 엔진에는 한국형발사체(KSLV-II) 2단에 사용된 75톤 엔진을 사용하고, 2단 엔진에는 과기부의 소형발사체 개발역량지원사업을 통해 개발하는 고성능 3톤급 메탄 엔진을 사용하는 것으로 설정하였다. 설계 과정에는 체계공학(System engineering) 기법을 적용하여, 운용개념 분석에서부터 요구사항 분석, 발사체 Staging 설계 및 형상설계(Sizing 및 Layout 설계), 그리고 임무분석까지의 연구를 수행하였다.
