The camber and gradient can be scaled linearly to the required Cl value. Of the maximum camber at a coefficient of lift (Cl) value of 0.3. 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% chordĠ = 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. NACA 5 digit airfoils in the database NACA 22112 NACA 23012 NACA 23015 NACA 23018 NACA 23021 NACA 23024 NACA 23112 NACA 24112 NACA 25112 Design coefficient of lift You can input any four digits in the airfoil box to generate a shape for a thickness-to-chord (t/c) ratio of 0.2. Using the guide program in MATLAB I have created a GUI for displaying geometries of NACA airfoils. 824, 1945.NACA 24012 Airfoil cl=0.30 T=12.0% P=20.0% I present a simple yet effective way of getting airfoil geometries. and Stivers, Louis S., Jr.: Summary of Airfoil Data. and Von Doenhoff, Albert E.: Theory of Wing Sections. and Hill, Acquilla S.: Computer Program To Obtain Ordinates for NACA Airfoils. and Brooks, Cuyler W., Jr.: Development of a Computer Program To Obtain Ordinates for NACA 4-Digit, 4-Digit Modified, 5-Digit, and 16-Series Airfoils. and Brooks, Cuyler W., Jr.: Development of a Computer Program To Obtain Ordinates for NACA 6- and 6A-Series Airfoils.

All of these m-files are free and you may use or modify them as you like. The program then plots each individual airfoil, and lofts the two together in an isometric view. This page contains my library of MATLAB function m-files for aerodynamics problem solver. Y_e -> Extrados y coordinate of airfoil vector (m) The program takes inputs of the NACA airfoil number, desired chord length, angle of incidence (AOI), and the wing length. X_i -> Intrados x coordinate of airfoil vector (m) S -> Number of points of airfoil (1000 default)Ĭs -> Linear or cosine spacing (0 or 1 respectively) (1 default)Ĭte -> Opened or closed trailing edge (0 or 1 respectively) (0 default)Īlpha -> Angle of attack (º) (0º default) OUTPUT DATA x_e -> Extrados x coordinate of airfoil vector (m) INPUT DATA n -> NACA number (4, 5 or 6 digits) OPTIONAL INPUT DATA c -> Chord of airfoil (m) (1 m default) It also plots the airfoil for further comprovation if it is the required one by the user. This function generates a set of points containing the coordinates of a NACA airfoil from the NACA 4 Digit Series, NACA 5 Digit Series and NACA 6 Series given its number and, as additional features, the chord, the number of points to be calculated, spacing type (between linear and cosine spacing), opened or closed trailing edge and the angle of attack of the airfoil. In the example M2 so the camber is 0.02 or 2 of the chord P is the position of the maximum camber divided by 10. NACA 2412 then: M is the maximum camber divided by 100. NACA 2412, which designate the camber, position of the maximum camber and thickness.
