NACA Wing Sections
thingiverse
This script produces merged wing sections. Each wing section is specified from root and tip, using coordinates X,Y,Z, Chord and rotation in space. A NACA airfoil profile is swept from root to tip with the NACA asymmetrical profile. I created this planform generator to manufacture ribs and internal components. It might be overkill for OpenSCAD. Check out the Wikipedia article on the NACA Airfoil 4-digit profile for mathematical details. The connection of the sections is in the XY plane. Someone else involved with OpenSCAD developed the sweep.scad file, but I'm unsure who deserves credit.
With this file you will be able to print NACA Wing Sections with your 3D printer. Click on the button and save the file on your computer to work, edit or customize your design. You can also find more 3D designs for printers on NACA Wing Sections.
