Hi Kees,
here a pic of aerodinamic fields on thin airfoils
and how to arrange multiple wings in order to not lost lift and gain drug
As you can see most of the lift was generated by pression/depression fields in the first 1/3 of airfoil
both of the pics comes from
E. Garuffa L'aviazione II ed. 1919 Koloman Mayrhofer collection.
cheers
Paolo
