← ScienceWhich outcome reduces a wing's lift when exceeding the critical angle of attack?
A)Boundary layer flow separation occurs✓
B)Increased viscous drag effects appear
C)Reynolds number significantly diminishes
D)Airfoil reaches its critical temperature
💡 Explanation
Boundary layer separation occurs across the upper wing surface causing a stall because pressure rises rapidly downstream, therefore, the airfoil loses lift rather than gaining it and temperature contributes significantly less than flow.
