The Split Scimitar design as seen at Denver International Airport on a Boeing 737 of Southwest Airlines. APB's Split Scimitar Winglet retrofit program consists of retrofitting 737NG's winglets by replacing the aluminum winglet tip cap with a new aerodynamically shaped "Scimitar" winglet tip cap and by adding a new Scimitar tipped ventral strake.
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 ...
The Masak winglets were originally retrofit to production sailplanes, but within 10 years of their introduction, most high-performance gliders were equipped from the factory with winglets. [6] It took over a decade for winglets to first appear on a production airliner, the original application that was the focus of the NASA development in the ...

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 ...
