The stall of the wing occurs at the highest liftcoefficient on an airfoil, when the airflow can no longer go around the airfoil's nose (leading edge) and separates from the upper wing surface.
机翼失速的发生在电梯表面系数最高的机翼上，当气流不能继续围绕翼型的鼻子(领先)，并脱离机翼上。

On this type of airfoil vortex generators (also called micro-vortex generators, or VGs) add very little improvement with respect to the maximum liftcoefficient (or stall speed).
Also the effect of different ice shapes on lift and drag coefficient were assessed. The results indicate that the glaze ice has the most adverse impact on airfoil aerodynamic performance.
