Based on the thermal environment of the inlet surface of the scramjet
the structure thermal protection was proposed to provide efficient protection for the inlet surface.Two thermal structure schemes for the inlet surface were designed
including net structure and corrugated sheet structure.And the thermal protection effect of two schemes was simulated.The results indicate that
two thermal structures could achieve efficient thermal protection within the permissible temperature range.Based on comparative analysis
it shows that the corrugated sheet structure has better thermal protection effect.
