I would like to pose some questions, of a very basic nature, in the interest of establishing a foundation.
1 How accurate is it to use the term, "flow" when teaching lift? Would a better term be "displacement"? The salient vectors are Normal to the streamlines, not horizontal, yes?
2. So are we saying that the air in proximity to the wing is accelerated instantly to say, 250 knots? Or is it forced to inhabit somewhat less volume than prior to entry of the wing? If it accelerated, would there be enough energy to accomplish lift?
3. Last, I don't believe in suction, because I was taught not to. Differential, yes.
If you do, could I describe suction as:
The inability of the airmass to form a "void"?
Sorry Lyman, but when you ask "questions" like that my notable patience runs out.
