Abstract

Through the KSLV-II, a turbine drive system(high pressure air supply system + alcohol burner) for the turbopump real-propellant performance test of the 75-tonf/7-tonf liquid rocket engine was developed. The turbopump of the staged combustion cycle liquid rocket engine, which has been in development as a next-generation launch vehicle, requires more power than that of the turbopump used in the KSLV-II. Therefore, the TPTF(turbopump real-propellant test facility) needs to be improved the performance of the turbine drive system for the development test of the turbopump assembly. In this study, the performance improvement process of the turbine drive system was summarized, and the results of the alcohol burner development test for generating turbine drive gas were analyzed.

한국형발사체개발사업(KSLV-II)을 통해 75톤/7톤 액체로켓엔진의 터보펌프 실매질 성능시험을 위한 터빈구동 시스템(고압공기 공급시스템+알코올버너)이 개발되었다. 후속발사체로 개발중인 다단연소 사이클 액체로켓엔진의 터보펌프는 한국형발사체에 사용된 터보펌프보다 더 큰 동력을 요구한다. 따라서 터보펌프 실매질 시험설비는 터보펌프 조립체의 개발시험을 위한 터빈구동시스템의 성능개량이 필요하다. 본 연구에서는 터빈구동시스템의 성능개량을 위한 과정을 정리하였고, 터빈구동가스 생성용 알코올버너의 개발시험 결과를 분석하였다.
