A blended winglet is attached to the wing with a smooth curve instead of a sharp angle and is intended to reduce interference drag at the wing/winglet junction. A sharp interior angle in this region can interact with the boundary layer flow causing a drag inducing vortex, negating some of the benefit of the winglet.
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.

[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]
By definition, it is the amount of energy gained by the charge of a single electron moved across an electric potential difference of one volt. electronegativity A chemical property that describes the tendency of an atom or a functional group to attract electrons (or electron density) towards itself. electronics
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 ...

The Scimitar Mark 2 combat vehicle is one of five enhanced CVR(T) types. [10] It was created in early 2010, and continues in service. [11] The Scimitar Mk II was: Rehulled to give better mine-blast protection for troops; Improved armour fitted to enhance resistance to blasts and ballistic threats
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 ...
