Excellent paper on how a wing actually "works".

Actually anybody wanting to know about the origins of lift on an aefoil would be better off reading

Elementary fluid dynamics by D.J. Acheson

and also

A first course in fluid dynamics by A.R. Paterson

Fundamentals of hydro- and aeromechanics by Prandtl and Tietjens.

All these books explain that the lift originates from the bound vortex (circulation) around the wing. The Kutta condition follows from the requirement of an attached boundary layer in the limit of infinite Reynolds number; i.e. the inviscid flow is consistent with the (possible) existence of an attached boundary layer since all other solutions would lead to separation and a breakdown of the inviscid flow solution.
