A numerical study has been conducted to investigate 1-D steady/unsteady start-up characteristics for liquid rocket engine using SINDA/FLUINT. First, to verify analysis of cryogenic fluid, the object is selected RL-10 engine, liquid rocket engine of expander cycle method. Pressure drop in the cooling jacket was modelled by including some orifice devices. As a result comparisons of numerical and experimental results, there are maximum 3.14% errors by assumptions and performance curves. Analysis of cryogenic fluid is verified for liquid rocket engine. Based on these results, analysis is performed RD-8, liquid rocket engine of staged combustion cycle method. As a result comparisons of numerical and experimental results, tendency of start-up characteristics show similar behavior. It is usable to analysis of liquid rocket engine.
