They started setting a number of World Records in performance with the winglets. [2] In 1997, API's winglets were sold as a standard fit on all Boeing Business Jets, and winglets were offered as an addition to standard 737s. Around 95% of all 737 customers want winglets fitted.

The fence/winglet drives the area where the vortex forms upward away from the wing surface, since the center of the resulting vortex is now at the tip of the winglet. [citation needed] The fuel economy improvement from winglets increases with the mission length. [14] Blended winglets allow a steeper angle of attack reducing takeoff distance. [15]
[87] [88] Continental Airlines was the first carrier to order winglets for the 757-200, and in February 2009 became the first operator of 757-300s with winglets. [89] Aviation Partners further developed the blended winglet into the Scimitar Blended Winglet, which improves fuel burn by 1.1% over the original blended winglet. [90]
Split Scimitar winglets were developed by Aviation Partners, the same Seattle-based corporation that developed the blended winglets; the Split Scimitar winglets produce up to a 5.5% fuel savings per aircraft compared to 3.3% savings for the blended winglets. Southwest Airlines flew their first flight of a 737-800 with Split Scimitar winglets on ...
A scimitar (/ ˈ s ɪ m ɪ t ər / or / ˈ s ɪ m ɪ t ɑːr /) [1] is a single-edged sword with a convex curved blade [2] [3] [4] of about 76.2 to 91.44cm (30 to 36 inches) associated with Middle Eastern, South Asian, or North African cultures.
The Spiroid winglet is a closed wing surface attached to the tip of a conventional wing. Wingtip vortices form a major component of wake turbulence and are associated with induced drag, which is a significant contributor to total drag in most regimes. A closed wing avoids the need for wingtips and thus might be expected to reduce wingtip drag ...
