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.
[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]
APB expects Scimitar Winglet Systems installed on a 737-800 to save the typical airline more than 45,000 gallons of jet fuel per aircraft per year resulting in a corresponding reduction of carbon dioxide emissions of 476 tons per aircraft per year. The fuel savings can enable a 737-800 to increase its payload up to 2,500 pounds or increase its ...
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 ...
Two styles of scimitars: an Egyptian shamshir (left) and an Ottoman kilij (right). 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 Scimitar was used by the three formation reconnaissance regiments of the British Army. After the Strategic Defence and Security Review in 2010, some regiments' Challenger 2 tanks were replaced with CVR(T) Scimitars. [22] The Scimitar was retired from active service in April 2023.

A small, freely-moving projection on the anterior edge of the wing of modern birds (and a few non-avian dinosaurs)—a bird's "thumb"—the word is Latin and means 'winglet'; it is the diminutive of ala, meaning 'wing'. Alula typically bear three to five small flight feathers, with the exact number depending on the species.
