Some airfoil formulae, like the NACA series, calculate maximum thickness perpendicular to the camber line so there can be some small discrepancies. During parsing the top and bottom surfaces of the airfoil are stored separately. The surface with the larger number of points is used as the master.
Airfoil database list A list of all the airfoils in the database in alphabetic order. Follow the links for details of the airfoil, image and polar diagrams. Alternatively, you can use the airfoil database search page to filter and order the airfoils by camber, thickness and name.
NACA 4 digit airfoil specification This NACA airfoil series is controlled by 4 digits e.g. NACA 2412, which designate the camber, position of the maximum camber and thickness. If an airfoil number is
Generated airfoil shapes Cambered plate airfoils A simple and effective way of making blades for small wind turbines is to cut the blades from sections of metal or PVC pipe. The angle and twist of the blade can be controlled by the shape of the cut and the curve of the pipe approximates to an airfoil shape. When the airfoil is normalised, the camber and thickness of the blade depends on size ...
Reynolds number calculator for airfoils. Input the speed (velocity), chord width and viscousity to calculate the Reynolds number for a wing, blade, or keel. Example viscousity values for air and water supplied
Without the aerodynamic forces of lift and drag, aircraft would be unable to fly, wind turbines would not spin, and countless other machines that we depend on every day would not work. What, exactly, ...
