NACA 4-Digit airfoil plotter. *Additional separate outputs for camber line, upper surface and lower surface Why is it that when I hit run, it doesn't look like the picture you have displayed? The position of the upper and lower surface can then be calculated perpendicular to the camber line. The plot configuration is different between yours and the image, that's why. I'm having difficulty getting it to run, could anyone tell what I should do after i create both provided function files? The airfoil pro le is determined by three parameters, which correspond to the four digits of the NACA airfoil. 4.0. Other MathWorks country sites are not optimized for visits from your location.

NACA 4 Series Airfoil Generator The calculator below can be used to plot and extract airfoil coordinates for any NACA 4-series airfoil. In this work, blockMesh is adapted to generate 2D mesh for an NACA airfoil (can be 4 or 5 digit). The NACA airfoil section is created from a camber line and a thickness distribution plotted perpendicular to the camber line. In the example P=4 so the maximum camber is at 0.4 or 40% of the chord. Generates the NACA 4 digit airfoil coordinates. Plots a 4-digit and 5-digit NACA airfoil. The first number is how much camber the foil has. A Description of the NACA 4-Digit System.
