Constructor Detail

NACA6Series

public NACA6Series(double CLi,
                   double thickness,
                   double length)

Create a NACA 6 series airfoil with the specified parameters.

Parameters:

CLi - Design lift coefficient (e.g.: 63-206 has CLi = 0.2).

thickness - The thickness to chord ratio (e.g.: 0.20 ==> 20% t/c).

length - The chord length.
