Ge Genex Powered.... Too wide, cant get into the gates and older airports, reduces wing length The cowlings are mfg by Ace Clearwater..

It appears to be a spoiler of some type for roll control. Unique application for sure.

Username Protected wrote: Thank you, Matt It seems like Boeing has been focused on weight reduction and using more carbon fiber recently, so it's interesting that the compromise in this case leaned toward the wing-folding solution despite the added weight and complexity. Reducing drag is going to save more Jet A than the weight penalty, especially on long routes.

In some installations they perform better than a winglet. My Cardinal has sheared wingtips designed by Roy Shobchuck. They tested better than the various winglets he investigated. NASA did a lot of wind tunnel test on them in the late '80s and early '90s. The only downside for me is my plane now has a wingspan of 39' 3", and my hangar clearance is about 6" on each side. Vince

Carbon changed the tradeoff. Folding wingtips were initially offered on the 777's metal wing but no airline bought them, IIRC they weighed 3,600 lbs. On the 777X carbon wing they only add about 400 lbs if memory serves and all airlines wanted them, they were made standard.
