jtt,
ARINC already pointed out both of them must hold at once and you can't just say "it's flying because of Bernoulli" or "it's flying because of N3".
I totally appreicate that. I guess I'm still hunting along the lines of my initial thread starting question related more to the primary reason for lift. The books say Bernoulli, but as a primary reason I am/was not convinced.
f the air would move completely straight (i.e. horizontally) above the wing it would pull away some of the molecules behind the leading edge of the wing (on the lee side) due to friction. That would produce a lower pressure where these molecules now are missing, pulling the following air mass coming over the edge of the wind downwards. As a net result the air going over the top of the wing also gets accelerated downwards, adding further lift, again due to N3. Actually, this second contribution seems to produce the major part of the lift.
Ah yes! That is exactly what I was hopelessly trying to describe when I called it the "blanking effect". Thank you for an incredibley lucid and understandable descripiton

Mugi,
I wonder how aircraft in ground effect are explainable, with regards to any of the 'models'?
Good question. This article explains things in a convincing manner. Whether it is true or not...
