← ScienceWhich outcome results when a supercritical airfoil exceeds its design Mach number?
A)Shock-induced boundary layer separation✓
B)Laminar flow transitions occur
C)Reduced skin friction drag evident
D)Increased structural vibration damping present
💡 Explanation
Shock-induced boundary layer separation results because a sharp pressure gradient forms due to the shock wave; this mechanism forces the boundary layer to detach. Therefore, flow separation stalls the airfoil rather than exhibiting reduced drag, which depends on attached flow.
