Abstract

A turbopump real-propellant test facility(TPTF) is to verify the performance of a turbopump unit(TPU) based on liquid oxygen and kerosene. One of the most important sub-facilities is a hot-gas generation system which makes the driving force of the TPU with an alcohol burner. The alcohol burner generates the required flow rates and temperature at the facility using high pressure air and ethanol. In the study, the verification tests of the alcohol burner which was manufactured entirely with domestic technology were performed and fabrication technique and operation skill for the burner could be obtained ahead of the construction of the facility. Two burners will be operated simultaneously for the real-propellant test of 75tf class turbopump and satisfy the power requirement from the turbine of the TPU.

터보펌프 실매질 시험설비는 액체산소와 케로신을 토대로 터보펌프 조립체의 성능을 검증하는 시험설비이다. 이 시험설비 중에서 가장 핵심적인 부분은 터보펌프의 구동력을 생성시키는 고온공기 생성시스템이다. 고압공기와 에탄올을 사용하는 알코올버너에 의해 시험시설에서 요구되는 유량과 온도가 생성된다. 본 연구에서는 국내기술로 제작한 알코올버너의 개발시험을 수행하였으며, 터보펌프 실매질 시험설비 구축에 앞서 버너의 제작기술과 운용경험을 확보할 수 있었다. 75톤급 터보펌프 실매질 시험에서는 이 알코올버너가 2기 동시 운용되어 터빈이 요구하는 구동력을 충족시킬 것으로 보인다.
