Airfoil DAT to Spline

Airfoil DAT to Spline




All aircraft developers struggle to make airfoil for wings, tails or propellers. A manually created spline will not guarantee precision of shape. Airfoils are represented as a set of X and Y coordinates in the DAT files. These coordinates should be multiplied on wing chord to get real X and Y coordinates of all points.


This script automates the creation of spline on selected construction plane or origin plane from any DAT file with defined chord length.


DAT files could be found from following sites:
