← ScienceWhich outcome results when airflow exceeds design limits around an aircraft wing?
A)Pressure gradient inversion causes stall✓
B)Turbulent kinetic energy dissipates smoothly
C)Lift vector aligns with thrust
D)Boundary layer remains fully attached
💡 Explanation
Stalling occurs because the adverse pressure gradient overcomes momentum within the boundary layer, causing flow separation and turbulent wake identified using the airfoil's pressure distribution equation. Therefore, lift is sharply reduced, rather than increased turbulence, because turbulence already exists downstream on a normal operational profile.
