Validated numerical approach and shock polar diagrams method were employed to investigate the flow structure and aerodynamic heating environment around high-mach flat- sweepback leading edge. The results demonstrated that with the increase of sweepback, the flat angle shock and leading edge shock crossed, and then Ⅳ, Ⅴ, Ⅵ shock-shock interactions were formed in turn. In general, the local pressure and heat flux increment caused by shock-shock interaction decreased with the increase of leading edge, but heat flux and pressure of interference zone under the transition Ⅳ shock-shock interaction might be lower than that under the typical Ⅴ shock-shock interaction. Moreover, it was found that the induced heat flux increased with the increase of attack angle, and decreased with the increase of Reynolds number. Also, a convenient discriminant method for high-Mach leading edge shock-shock interaction was provided based on critical deflection angle analysis. The discriminant results were validated against numerical results. The shock-shock interaction relation, interaction location and interference type graph for high-Mach leading edge was presented. The findings could benefit not only high-Mach aircraft integrated design, but also aerodynamic configuration optimization.
