Abstract

Upper stage of the Korea Space Launch Vehicle-II(KSLV-II) uses a 7-tons class liquid rocket engine and is an open gas generator cycle with a turbopump supply method that uses kerosene/liquid oxygen as the propellant combination. This study first provided a brief overview of the design and development process of the upper stage engine. In addition, it introduced the solutions and results applied to some of the problems that occurred during the development process of the upper stage engine.

한국형발사체(KSLV-II) 상단은 7톤급 액체로켓엔진을 사용하고, 케로신/액체산소를 추진제로 사용하는 터보펌프 공급방식의 개방형 가스발생기 사이클이다. 본 연구에서는 우선 7톤급 상단엔진의 설계 및 개발과정에 대한 간략한 개요를 제공하였다. 또한 상단엔진 개발과정에서 발생했던 문제점 중 몇 가지 사례에 대해 적용된 해법 및 결과들을 소개하였다.
