| Abstract: | The inlet of RBCC(rocket based combined cycle) engine ground-test prototype operated in rocket ejector mode and ramjet mode(Mach number from 0 to 4.0) was investigated.The 2-D(two-dimentional) inlet with strut was designed.Through numerical simulation,a comparative analysis of the performance and the inner flow with/without strut in the inlet in ramjet mode was made,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. |
