← ScienceWhich outcome causes lift reduction as supersonic air accelerates past a wing according to the Prandtl-Glauert transformation?
A)Increased induced drag on the wing
B)Shock wave formation on airfoil surface✓
C)Boundary layer separation increases rapidly
D)Decreased skin friction along chord
💡 Explanation
Shock waves form due to air compressibility as the speed passes Mach 1, because airflow significantly changes and pressure increases abruptly per the Prandtl-Glauert, therefore lift reduces; rather than induced drag.
