The Mathematical Secret of Flight
I have just upon invitation submitted the article The Mathematical Secret of Flight to Normat Nordisk Matematisk Tidskrift.
The article explains in easily understandable form how a wing generates lift at the expense of small drag, based on a stability analysis of potential flow and computations of turbulent solutions of the incompressible Navier-Stokes equations for slightly viscous flow. It is also shown that the state-of-the-art explanation of lift by Kutta-Zhukovsky based on connecting lift to circulation, is physically incorrect.
The new explanation of the mathematics and physics of flight is also presented in the knol
Why It Is Possible to Fly including more references to my work with Johan Hoffman.
