VisualFoil NACA is similar to the full version of VisualFoil 5.0. The software accurately computes lift, drag, moments for NACA 4, 5 and 6-series airfoils. It is based on a linear strength Vortex panel method coupled with a boundary layer solver. The camber and gradient can be scaled linearly to the required Cl value. VisualFoil NACA is a NACA airfoil generator and airfoil analysis software package. Of the maximum camber at a coefficient of lift (Cl) value of 0.3. The 15 indicates that the airfoil has a 15 thickness to chord length ratio: it is 15 as thick as it is long. XFOIL is an interactive program for the design and analysis of subsonic isolated airfoils. The values for the constants r, k 1 and k 2/k 1 are tabulated for various positions There are also different equations for standard and reflex camber lines. The equation for the camber line is split into two sections like the 4 digit series but the division between the two sections is not at the point of maximum camber. The maximum thickness as percentage.In the examble XX=12 so the maximum thickness is 0.12 or 12% chord. In the examble P=3 so maximum camber is at 0.15 or 15% chordÄ = normal camber line, 1 = reflex camber line The position of maximum camber divided by 20. It indicates the designed coefficient of lift (Cl) multiplied by 3/20.
