REPLY TO ALL--Misconceptions:Airfoil



I've been convinced enough by all our previous discussions on this to pull
the airfoil from my instructional set (although it's still in my Animated
Chalkboard software--too lazy to replace that one), but I still have
questions. Doesn't the air flow faster over the top of the wing than the
bottom for certain airfoils (for whatever reason) and doesn't that produce a
pressure difference--the essence of the Bernoulli approach. Yes other
things are going on, but with such a shape is NONE of the lift attributable
to a pressure difference? What about low speed airfoils--I'm especially
thinking about para-foils and human powered craft such as the Gossamer
Albatross--are those explainable totally in Newtonian versus Bernoulli(an)
terms?
