"It's complicated" actually kind of describes it. From the NASA website: "The real details of how an object generates lift are very complex and do not lend themselves to simplification...To truly understand the details of the generation of lift, one has to have a good working knowledge of the Euler Equations." - http://www.grc.nasa.gov/WWW/K-12/airplane/bernnew.html http://www.grc.nasa.gov/WWW/K-12/airplane/bernnew.html That said, I like this handling of it: http://www.amasci.com/miscon/miscon4.html#wing http://www.amasci.com/miscon/miscon4.html#wing
