The full size airfoil plot can be opened on a blank page for printing. The airfoil may optionally be plotted around the circumference of a circle, for example to match the radius of the vertical axis wind turbine or to change the camber. The links at the bottom of the page give some other sources of airfoil coordinates The airfoil thickness can be adjusted by altering the percentage thickness. The form at the bottom of the page can be used to retrieve the data and preview the airfoil shape. There is a much larger range of airfoil coordinates available on the University of Illinois airfoil coordinates database.
A number of airfoil section can be selected from the drop down menu. Plot and print the shape of an airfoil aerofoil for your specific chord width. Without javascript the functionality of this page may not work correctly, especially in older versions of Internet Explorer.

The following table presents the various camber-line profile coefficients:įour- and five-digit series airfoils can be modified with a two-digit code preceded by a hyphen in the following sequence: The formula for the shape of a NACA 00xx foil, with "xx" being replaced by the percentage of thickness to chord, is y t = 5 t, Plot of a NACA 0015 foil generated from formula The 15 indicates that the airfoil has a 15% thickness to chord length ratio: it is 15% as thick as it is long.Įquation for a symmetrical 4-digit NACA airfoil The NACA 0015 airfoil is symmetrical, the 00 indicating that it has no camber. įor example, the NACA 2412 airfoil has a maximum camber of 2% located 40% (0.4 chords) from the leading edge with a maximum thickness of 12% of the chord. Last two digits describing maximum thickness of the airfoil as percent of the chord.Second digit describing the distance of maximum camber from the airfoil leading edge in tenths of the chord.First digit describing maximum camber as percentage of the chord.The NACA four-digit wing sections define the profile by: These figures and shapes transmitted the sort of information to engineers that allowed them to select specific airfoils for desired performance characteristics of specific aircraft. Engineers could quickly see the peculiarities of each airfoil shape, and the numerical designator ("NACA 2415," for instance) specified camber lines, maximum thickness, and special nose features. By 1929, Langley had developed this system to the point where the numbering system was complemented by an airfoil cross-section, and the complete catalog of 78 airfoils appeared in the NACA's annual report for 1933. According to the NASA website:ĭuring the late 1920s and into the 1930s, the NACA developed a series of thoroughly tested airfoils and devised a numerical designation for each airfoil - a four digit number that represented the airfoil section's critical geometric properties. NACA initially developed the numbered airfoil system which was further refined by the United States Air Force at Langley Research Center.
