← ScienceWhich effect on airplane wing ice accumulation occurs when airfoil curvature increases?
A)Increased induced drag and lift
B)Lower stall speed; higher drag
C)Decrease in adverse pressure gradient
D)Earlier boundary layer turbulence threshold✓
💡 Explanation
Increased curvature accelerates airflow initially; this effect described within the Bernoulli equation precipitates earlier transition to turbulence because the adverse pressure gradient becomes steeper; therefore, boundary layer turbulence threshold is lowered rather than laminar flow delaying separation.
