After following C. Martin Faure's posts in recent weeks regarding winglets,
their use and lack thereof, and having seen today an article in Australian
Aviation that says the 767-400ER will now *not* have winglets but a "raked
wingtip" design I'm reminded of a question that has been in the back of my
mind for a while. This relates to the IL-96 and TU-204 Russian airliners -
both which have winglets, but both which *appear*(to the eye anyway) to be
way out of proportion (ie; too big) to the rest of the aircraft compared to
western types such as the A330/A340 and 747-400 winglets. Does anyone know
if it is because of the specific Russian designs, or that they've just done
a copy-cat perhaps without doing all the sums and maybe thought something as
simple as "bigger is better" ? Does anyone have any figures one way or the
other to determine if they help or hinder the Russian types?

trivia r us,
