Default Backwash Causes Lift?

I think you mis-understood me here. When I say the air below the line
is pressing upward, I am not referring to the air pressing upward on
the bottom of the wing. I am referring to the air _inside_ the wing
pressing upward on the underside of the top surface of the wing. The
air above the wing top surface has lower than normal pressure. The
air inside the wing has normal pressure. So it presses upward on the
top surface of the wing. This is lift generated by the top surface of
the wing.


Air _inside_ the wing. Hmm...please don't take this the wrong way, I
can assure I don't mean it as an insult, but what do you do for a
living and what is your technical bacground (math, physics, etc.) if
you don't mind my asking?

If air inside the wing pushes upward on the underside of the top of
the wing, it also pushes downward on the overside of the bottom of the
wing, thus nullifying any effect of the air inside the wing.


Wow, you're like, the next einstien, dude.
