Like Lou, this stuff brings back memories.... and the old flight test motto... "Fighting back the forces of ignorance and superstition one more day"
Martin Simons* book is invaluable.. I got mine recently in about a week from England thru Amazon. com (shameless plug! )
He lays out most of what has been discussed and cussed here...
figure 1 shows Bernoulli... the change in pressure due to a change in velocity.
Figure 2 shows the air ahead of the wing is influenced by the wing's presence (up to sonic velocities) and thus a "inflow-upwash" is created...
And Figure 3 shows how a propellor does the same thing..
