text: The airfoil is said to be stalled.
text: ; airfoils that stall at normal Rn at CL=1.3 stall instead around 0.8 at low Rn.
text: Notice that once the angle of attack exceeds a critical value the flow separates from the top surface of the airfoil, resulting in a precipitous reduction in lift and an increase in the drag (due to pressure drag); this is called the stall angle, and beyond this angle the airfoil is said to be stalled.
