I refer to: THE SECRET OF FLIGHT (DRAFT), December 5, 2011
1) page 105, formula 1.22
The term V x f seems wrong because the volume forces (f) are centered and thus lack of torque and you will always have V x f = 0.
This term must be replaced with V x (v V ²u) = v V ²ω according to http://en.wikipedia.org/wiki/Vorticity
because vorticity is always created and/or destroyed by the viscosity acting together to gradient of velocity in the direction normal to it.

I cannot understand how the vortex is made as there is needed a very strong circuitation that cannot be generated by the very small oscillations of the stagnation points at the trailing edge.
