초록
Rocket Based Combined-Cycle(RBCC) engines are currently being explored as advanced propulsion for space transportation. JAXA has been conducting RBCC engine research by using various experimental facilities. In order to clarify the experimental results and contribute to the improvement of designing, the analysis of the RBCC engine in an ejector-jet mode was carried out using the CFD code developed in-house for unstructured grids. CFD replicated the characteristic flow structures. The numerical simulation of the pumping performance of the ejector driven by different rocket gases(He,
