This article shows how to make a smooth wing part in FreeCAD from an airfoil section shape defined by coordinates in a file.
The wing has sweep, taper and twist and the thickness to chord ratio varies across the span. The result is a smooth 3D shape that follows the shape of the loaded airfoil section.
In part 1, we make a sketch of the planform. This is not strictly necessary, so you can skip straight to part 2 if you just want to see how to make the wing. |
