xf2sw is a small perl script that will convert your polars generated with X-Foil to a .polar file readable by Silent Wings.
You can download it here: xf2sw.tar.gz
The tarball contains a sample set of x-foil generated polars to demonstrate how it is done.
- Start X-Foil, load the airfoil geometry - Set a Reynolds number suited for the speed you want to use the airfoil in, or maybe use a variable Reynolds number coupled with CL? (this might give you a more realistic aircraft l/d polar) - Calculate a polar and output it to a file - Modify the airfoil geometry to a new flap setting - Calculate a polar to another file - continue until you're done
For a proper set of airfoils it's recommended to have at least 2 rudder deflections in both direction around zero deflections (5 polars in total).
