Abstract

Programs of energy balance, mode analysis and transient analysis for a liquid rocket engine have been introduced. The analysis methods have been verified through comparison between the present results, and the results of the other program and experimental data. An energy balance analysis is used for engine system design at the early development phase. A mode analysis is used for decision of engine operation conditions and test conditions, and studying deviation of an engine performance. A transient analysis can predict a propellant flow rate, thrust, impulse at transient phase. It is essential to establish a startup/shut down sequence. The analysis programs will be used to develop the engines of KSLV-II.

액체 로켓 엔진에 대한 에너지 밸런스 해석, 모드 해석, 비정상 해석 프로그램을 소개하였다. 유사 프로그램에 대한 결과, 공개된 실험 결과와 비교하여 해석 방법을 검증하였다. 에너지 밸런스 해석은 초기 개발 단계에서 활용된다. 모드 해석은 엔진 작동 조건, 시험조건 설정 및 엔진 성능 분산 분야에 활용된다. 비정상 해석을 통하여 추진제 유량, 추력, 비정상 조건에 대한 임펄스를 예측할 수 있다. 비정상 해석은 시동/종료 시퀀스 설정에 필수적이다. 본 해석 프로그램들은 한국형 발사체 엔진 개발에 활용될 것이다.
