Flowfields in a scramjet engine inlet were numerically simulated by the Navier-Stokes equations with a turbulence model, and aerodynamic effects of the strut position in the scramjet engine inlet were also investigated. Because the RJTF experiments reveal that characteristics of scramjet engine performances are quite dependent on the strut positions. To investigate the RJTF experimental results, the computations were conducted for inflow Mach number of 5.3 on NAL’s Numerical Space Engine. The correlations were obtained between the inlet flowfields and the struts position, and the effects of the RJTF nozzle flow boundary layer were clarified.
