Create airfoils of a wing using the airfoil optimizer Xoptfoil-JX, also create a wingplan and a model of the wing that can be imported by XFRL5 / FLZ Vortex for simulation purposes

Find an article about the first prototype on:
https://www.rc-network.de/threads/the-strak-machine.11818595/

1. Create a wing and position the airfoils by simply putting some parameters in a textfile

Choose between 'user'- (already exisiting), 'blend'- (generated by geometrical interpolation) and 'opt'-airfoils (generated by the optimizer)

2. Setup the objectives for the optimizer Xoptfoil-JX, using a graphical editor

A short video that will explain the usage of the graphical editor can be found here:

3. Run the optimizer to generate the 'opt'-airfoils

4. Generate polars, import the generated airfoils, polars and the complete wing or plane into XFLR5 /  FLZ Vortex and simulate!
