Figure 6-2. Typical variation of airfoil lift and drag coefficients with angle of attack
and aspect ratio, illustrating the flow regimes used to characterize airfoil behavior.
(a) Lift coefficients for an
NACA 4415
airfoil tested at a Reynolds number of 0.5 million.
(b) Drag coefficients for the same airfoil [Ostowari and Naik 1984]
