Abstract : A theory analogous to that given by Riegels for thin profiles in uniform flow is developed for flows of exponential type U(y) = ae(cy) + be(-cy). By this method the velocity distribution of any profile with moderate thickness and small camber can be calculated approximately by solving the integral equation of the flat plane airfoil as described in Part I (AD-610 445) and by numerical integration of known functions. Formulas for the corresponding lift and moment are derived. (Author)
