Hypersonic aerodynamic heating problem has been investigated for the shock-shock interactions of two hemi-sphere cylinder problem for future TSTO space transport systems. Two hemisphere models with a diameter of 3 cm and 6 cm are placed parallel or with the inclined angles and hypersonic wind tunnel tests have been made by NAL Mach 10 HWT. Severe local peak heating is generated on the small hemisphere nose by strong shock-shock interactions of Type 3 at the inclined angle of 15 deg. In the parallel setting cases at high angles of attack. Type 1 and Type 2 shock interaction patterns are observed. CFD computations can predict local peak heating accurately in the interaction area and the structure of shock-shock, shock-boundary layer interaction can be resolved in detail.
