Design and Numerical Investigation of RBCC Prototype Inlet

摘要

This paper tries to investigate the inlet of RBCC ground-test prototype operated in rocket ejector model and ramjet model (0～4Ma). The 2-D inlet with strut was designed. Through numerical simulation a comparative analysis was made of the performance and the inner flow with and without strut in the inlet in ramjet mode, whereas rationality of the design was verified and a rule was derived for the variation of the performance of RBCC prototype's inlet which was induced by the change of the location or the configuration of strut. Finally, an optimized configuration was obtained.
