WebThe circulation theory presented earlier deals with the simple case of circulation around a wing (sail, fin) of indefinite length. … As the wing moves forward, it sheds a starting vortex, equal to but opposite in circulation to the wing vortex, called the bound vortex, bound as it is to the wing. What is circulation theory?

WebDec 8, 2014 · The obvious answer is that the air around the wing isn't irrotational. But that seems a bit too simple: they're implying that there's a possible contradiction here. I suspect that the answer is in Bernoulli's or Euler's equations, which I've heard are linked to why planes fly. But that's well ahead in my notes and I don't understand any of that ...
WebMay 20, 2008 · "Circulation" around a wing deceases as air speed increases. As air speeds approach mach 1, for example a 747 flying at mach .85 to mach .90, there is no significant forward (relative to a wing) flow of air anywhere on a wing. The axis of wing tip vortices is close to parallel to the direction of travel. The axis of turbulent vortices above …
