초록

한국형발사체를 위한 액체로켓엔진은 터보펌프 추진제 공급방식의 시스템으로 이루어진다. 이 터보 펌프의 실추진제를 사용하는 실험적 성능검증을 위해 액체산소와 케로신을 토대로 한 터보펌프 실매질 시험설비가 구축되어 왔다. 산화제/케로신 공급 시스템과 알코올버너 시스템과 같은 주요 서브시스템에 대한 검증시험이 이루어 졌고, 터보펌프 개발모델을 이용한 인증시험을 통해 전체 시험설비에 대한 성능검증이 이루어 졌다. 설계점 및 탈설계점을 포함한 터보펌프의 모든 운용조건과 운용시간에 대한 실매질 성능검증시험을 본 시험설비를 이용하여 수행할 수 있는 것으로 확인되었다.

Liquid rocket engines of KSLV-II employ a turbopump feed system for propellants. A turbopump real-propellant test facility based on liquid oxygen and kerosene has been constructed for the experimental verification of the turbopump performance using the real media of propellants(i.e., LOX/Kerosene). The verification tests of sub-systems were performed such as LOX/kerosene feed system and alcohol burner system. Finally, the performance of the whole system was executed and verified through a sets of validation tests with the development model of the KSLV-II turbopumps. It has been confirmed that the test facility satisfies the operating conditions and time of the turbopump at the design and off-design performance test using real-propellant.
