These scaled psi and epsilon functions are used in mapping the z-plane to the z'-plane shown in Figure 1.

Then, the scale factor is used to multiply the basic values of the psi and epsilon functions for this airfoil family. From the thickness, the scale factor is computed from the polynomial function shown above. Now, for a specified family and thickness, the thickness distribution may be determined without iteration. And then the reference continues with this head spinning further explanation: $c_f$ is the particular scale factor for this profile.

However, I am not able to find the correct parameters to draw it, so that it would match up with the coordinates given in the table above.ī = 1.0 % caution for NON-unity entries change the equation for h In relation to the question on the NACA 64-2A015 airfoil I would like to know how to draw this airfoil.Īt least these two reports by NASA provide the equation for it.
