Abstract

The technology development of a high performance upper stage engine for a GEO(GEostationary Orbit) KSLV(Korea Space Launch Vehicle) is undergoing in Korea Aerospace Research Institute. KSLV is composed of an open cycle engine with gas generator, which is for a low orbit launch vehicle. However the future GEO launch vehicle requires a high performance upper stage engine with a high specific impulse. The staged combustion cycle engine is necessary for this mission. In this paper, current progress and future plan for staged combustion cycle engine development is described.

항공우주연구원에서는 정지궤도용 우주발사체에 적용 가능한 고성능 상단 엔진에 대한 선행기술 개발이 진행 중에 있다. 한국형발사체(KSLV)는 gas generator를 이용한 개방형 사이클 엔진이며, 저궤도 위성 발사를 위한 발사체로 향후 정지궤도위성 발사체를 위해서는 이보다 높은 비추력을 가진 고효율의 상단엔진이 필요하게 된다. 이러한 요구조건을 충족시키기 위해 다단 연소방식의 엔진이 필요하며, 본 논문에서는 당 연구원이 진행 중인 다단 연소 사이클 엔진 개발 진행 현황과 향후 계획을 기술하였다.
