Beware the separator (symbol) decimal will be the point (REQUIRED). Next, the data must be separated into respective columns within Excel. Before using CFD to generate lift and drag values, probably a good way would first be to validate your method with this data . Using MS Excel inter the profile data in a worksheet, the profile is a ratio of the wing cord, so you need to multiply the values by the cord to get the real airfoil dimisions. The coordinates are based upon the method outlined in Riblett's book. In the section about the NACA 4-digit airfoils (section 6.4, page 113) they state the following: "When the NACA four-digit wing sections were derived, it was found . Generate airfoil coordinate in excel spreadsheet with this format. Four-digit series airfoils by default have maximum thickness at 30% of the chord (0.3 chords) from the leading edge. aero_head likes this. NACA 2412, which designate the camber, position of the maximum camber and thickness. Airfoil data was read from selected files or generated using NACA airfoil equations with a variable number of points.

Use the applet to contrast the different characteristics of the airfoils that can be generated from this formulation. The NACA airfoil series The early NACA airfoil series, the 4-digit, 5-digit, and modified 4-/5-digit, were generated using analytical equations that describe the camber (curvature) of the mean-line (geometric centerline) of the airfoil section as well as the section's thickness distribution along the length of the airfoil. The formula for the shape of a NACA 00xx foil, with "xx" being replaced by the percentage of thickness to chord, is = [+], where: x is the position along the chord from 0 to 1.00 (0 to 100%), is the half thickness at a given value of x (centerline to surface), t is the maximum thickness as a fraction of the chord (so t gives the last two digits in the NACA 4-digit denomination divided by 100).
