Winglets, how do they work?
I know they provide a 3-4% saving in fuel burn and reduce induced drag, but why/how do they work?
Why don't the 777, 767 and 757 have them?
Do "Blended" winglets work better than normal winglets?
Thanks in advance.

With the winglets reducing drag by reducing the vorticees, do they lead to a significant wake vortex reduction on landing/takeoff, or is the reduction too small compared to the turbulence caused by higher angles of attack ?

You could also perform some searches on the PPRuNe Forums, lots of threads about winglets. See for instance :

bentandtwisted,
haven't had a chance to check out all the above links,but try a search of 'supercritical wing' or 'reflex camber'.it may help answer your B777 etc question.
blended vs normal winglets, my guess would be blended wins.
safe flying, hoss
