Abstract

In this paper, mathematical models of a simulation code are presented. The simulation code was developed for the startup analysis of an open cycle liquid rocket engine (LRE). Most of the components comprising an LRE, including the priming process in the propellant feeding line, were considered. A startup simulation of a 75-tonf LRE, which was used for the KSLV-II test launch vehicle (TLV), was performed. The simulation results showed good agreement with the engine acceptance test results, thus proving the validity of the startup simulation code.

본 논문에서는 개방형 사이클 액체로켓엔진의 시동해석을 위해 개발된 해석 코드의 수학적 모델을 제시하였다. 추진제 공급 배관에서의 추진제 충진 과정을 포함하여 엔진을 구성하는 대부분의 요소를 고려하였다. 한국형발사체 시험발사체에 사용된 75톤급 엔진의 시동해석을 수행하였으며, 해석 결과와 실험 결과가 잘 일치함을 보임으로써 시동해석 코드의 타당성을 증명하였다.
