Helicopter aerodynamics
 

Does anyone know of an aerodynamics book which explains the detail air movement about an airfoil. I'm particularly after explanations of things like stagnation points, how boundary layer flows change with AoA, and the like.

Also, any ideas on where I can find out about "American Turnbuckles" ?

And in case you're wondering, my CPL(H) tech exams are in 3 weeks, I'm self-studying, and I've already tried 3 helicopter aerodynamics books and any web resources I can find to no avail.

Guys :

Ignore this, already answered in Tech Log.
