    Exporting an airfoil from profili

    On profili click on airfoil database (small yellow airfoil), then pick your air foil and chose export as a .txt file. See attached picture. Be carefull, for one reason I do not know, sometimes the first coordinate shows a negative value while it should be positive.

    aluminium ellipsoid DLG wing mould

    Does any one knows a guy who could machine aluminium moulds in 3/4" thick plates for my wings? I am ready to pay for it if not too expensive. Please contact me directly at [email protected]

    SuperGee2's wing has 3 profiles

Supposedly the spitfire had such type of wings and was better than those aircrafts with straight wings. I have attached the soft which computes Drela's type wings, that is a wing originally in two straight sections. Take AG47 for tip and AG 455 for root and run it step by step. You will have a wing close to Drela's. Usually one cuts such wings with a hot wire and templates made using the Profili software. Good luck.
    Hi Cocodet,

    You done the great job! And I just confused that on SuperGee2's design the wing has 3 prosiles: AG455ct (root), AG46ct (middle) and AG47ct (tip). In you software could just input root and tip.

    Thanks
