← ScienceWhich outcome occurs to lift when exceeding critical airfoil angle?
A)Flow separation stalls the wing✓
B)Lift increases beyond design limits
C)Drag decreases due to laminar flow
D)Induced drag is minimized completely
💡 Explanation
Flow separation stalls the wing when the adverse pressure gradient overcomes the fluid momentum according to the inviscid Bernoulli equation. This is because the adverse pressure gradient triggers boundary layer separation rather than increased lift or reduced drag, therefore lift suddenly decreases instead.
