'2412') No of panels (line elements) PER SIDE (upper/lower) Type of chord station spacing (Half cosine spacing / Uniform spacing) OUTPUTS: One can plot the generated airfoil, camber line and the leading edge circle by … For example, a NACA 2412 airfoil uses a 2% camber (first digit) 40% (second digit) along the chord of a 0012 symmetrical airfoil having a thickness 12% (digits 3 and 4) of the chord.
A NACA series 4 aerofoil generator, based on the equations and methods set out in Abbot and von Doenhoff’s classic student aerodynamicists’ text, Theory of Wing Sections.
This program is a complete revision of the NASA Langley programs for computing the coordinates of NACA … In the example XX=12 so the thiickness is 0.12 or 12% of the chord. The program naca456 is a public domain program in modern Fortran for computing and tabulating the coordinates of the 4-digit, 4-digit modified, 5-digit, 6-series and 6A-series of NACA airfoils.
NACA 4-Digit Series Airfoil Generator- a web based Java applet NACA 5-Digit Series Airfoil Generator - a web based Java applet SNACK - download this program that includes NACA airfoil coordinate generators for all of the families we have discussed (program is free to use for 30 days) 60 minutes NACA 4 digit airfoil specification This NACA airfoil series is controlled by 4 digits e.g. To draw on the screen and after print out your ribs and airfoils, use Tracfoil The program comes in the form of a window to define the different types of Naca. NACA 2412, which designate the camber, position of the maximum camber and thickness. m is the maximum camber (100 m is the first of the four digits), p is the location of maximum camber (10 p is the second digit in the NACA xxxx description). The last two digits, "12" specify that the maximum thickness of this airfoil section is 0.12c.
Code to generate 4 and 5 digit NACA profiles.
This program lets you make and save NACA airfoils files of 4-digit, 5-digit, Modified 4 and 5-digit, series 6, 6A and 16 as files in the format (Seling Files) nameFile.dat. NACA 2412 then: M is the maximum camber divided by 100. In the example P=4 so the maximum camber is at 0.4 or 40% of the chord. The NACA airfoil series The early NACA airfoil series, the 4-digit, 5-digit, and modified 4-/5-digit, were generated using analytical equations that describe the camber (curvature) of the mean-line (geometric centerline) of the airfoil section as well as the section's thickness … The second digit, 4, specifies that the maximum camber of this airfoil section is located 0.4c behind the leading edge.
The chord can be varied and the trailing edge either made sharp or blunt. Although the 4 series aerofoils are rather old (they were developed in the thirties) they are still useful for low-speed applications such as wind turbines or velomobile fairings.

The calculator below can be used to plot and extract airfoil coordinates for any NACA 4-series airfoil. At this four-hour workshop you will learn about the details of NACA's Purchase Program, the home buying process and start your NACA file. Using these numbers, the final shape of the airfoil section can be calculated.
