NACA Airfoils is an easy-to-use shareware program that you can download here free. It can print any NACA 4 or 5-digit airfoil to any scale with excellent precision on an ordinary laser, ink jet, or dot matrix printer. It is intended for use in model airplane design. Provision is made for camber, center of camber, chord, skin thickness, spar and leading edge dimensions (in inches or millimeters). A set of ribs for a whole tapered wing with a smooth airfoil transition from root to tip can be printed with a single click. The program can display pairs of airfoils on the screen for comparison and can generate files compatible with AutoCAD, ModelCAD, DesignCAD or Foiled Again!! (KelComp is not affiliated in any way with any of these companies.). It also will display outlines of the members of an airfoil library in various formats.Click to download now.
