F = ??U? where ? = ?C u · dl, is proportional to the circulation around the wing. 8.2 Kutta-Joukowski theorem. The above result is an example of a general exact general result of inviscid irrotational flow theory. Theorem 8.1 (Kutta-Joukowski). Any 2-D body in relative motion to the ambient fluid with velocity U has a lift force,
Joukowsky, Kutta, Prandtl and his students, Munk, Betz, and Von Karman. It should not be forgotten that the writings of F. W. Lanchester provide many of the physical insights that were elaborated in these mathematical theories. Throughout World War I, these developments in aerodynamic theory remained virtually unknown

The Kutta–Joukowski theorem is a fundamental theorem of aerodynamics, that can be used for the calculation of the lift of an airfoil, or of any twodimensional bodies including circular
2.5.1 Kutta-Joukowski Lift Theorem. The theory of conformal mapping tells us that it is possible to map any simply connected profile onto a circular cylinder. In the transformation, the flow past the profile maps into the flow past a circular cylinder derived earlier. The far field flow is preserved. The inverse transformation will
10 Dec 2011 Momentum balances are used to derive the Kutta-Joukowsky equation for an infinite cascade of aerofoils and an isolated aerofoil. These derivations are simpler than those based on the Blasius theorem or more complex unsteady control volumes, and show the close relationship between a single aerofoil

If an irrotational two-dimensional ?uid current, Joukowski came to their various conclusions about aerodynamics quite independently, and Wilbur Wright, had he
4 Jun 2013 namics, and will derive the result known as the Kutta-Joukowski theorem, which relates the lift force acting on a cylinder to the velocity of the cylinder relative to the surrounding fluid. To keep the mathematics simple, we will need to make a few key assumptions about the nature of the surrounding fluid.
The Kutta–Joukowski theorem is a fundamental theorem of aerodynamics used for the calculation of the lift of an airfoil and any two-dimensional bodies including circular cylinders translating in a uniform fluid at a constant speed large enough so that the flow seen in the body-fixed frame is steady and unseparated.
