BEMHAWT:
--------------------------------------------------------------------------
Torque produced by a wind turbine rotor using Glauert
blade element theory.
Type BEMHAWT for a demo
The default lift and drag function is LiftAndDragCoeff. Your function
is of the form [cL, cD] = MyFun( d, alpha )
which will be passed d.u = u0(1-a), and d.s = d.r(end)
--------------------------------------------------------------------------
Form:
[q, p, t] = BEMHAWT( d )
