No, it only generates 1/3 of the lift. The rest is generated by lower
pressure on the upper side.
I recommend you read
which explains the design and function of winglets.
But I`m teaching aerodynamics in my club and it is extremely hard to
explain this to people. I don`t want to confuse people with vorticity
fields so the explanation "pushing air down will result in an
underpressure on top and an overpressure on the lower side of the wing;
that`s lift" seems to be sufficient for the understanding of lift as
far as gliding is concerned.
Not too smart to post when you`re just woken up. For those who wanna
know why, just take a look at my last post ;-)
