Download The Secret of Flight by Johan Hoffman, Johan Jansson, Claes Johnson. In this book we present a mathematical theory of subsonic flight based on a combination of analysis and computation. By computing and analyzing turbulent solutions of the incompressible Navier-Stokes equations for slightly viscous flow subject to force boundary conditions, we uncover a mechanism for the generation of considerable lift at the expense of little drag of a wing, which is basically totally different from that envisioned within the classical theories by *****-Zhukovsky for lift and by Prandtl for drag.
