Like winglets, they increase the effective wing aspect ratio and diminish wingtip vortices, decreasing lift-induced drag. In testing by Boeing and NASA, they reduce drag by as much as 5.5%, compared to 3.5% to 4.5% for conventional winglets. [1] While an increase in span would be more effective than a same-length winglet, its bending moment is ...
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 wing sharklet of an A320neo aircraft. These sharklets are also optional add-ons for the classic A320 family. In 2006 Airbus started the A320 Enhanced (A320E) programme as a series of improvements targeting a 4–5% efficiency gain with large winglets (2%), aerodynamic refinements (1%), weight savings and a new aircraft cabin.
Airbus launched the sharklet blended winglets during the November 2009 Dubai Airshow. Installation adds 200 kg (440 lb) but offers a 3.5% fuel burn reduction on flights over 2,800 km (1,500 nmi; 1,700 mi), [53] saving approximately US$220,000 and 700 t of CO 2 per aircraft per year. [54]
Sharklet may refer to: Blended winglets on aircraft, specifically those manufactured by Airbus; Sharklet (material), a plastic sheet product
Feel free to add a few cracks of black pepper to the tops and bake for 5 to 7 minutes per side (flipping halfway through). Finish: Transfer the cooked dates to a wire rack, and top with a dash of ...

New winglets, 3.7 metres wider and similar to those of the A350 XWB, still within ICAO category E airport requirements, along with new engine pylons, would improve aerodynamics by 4%. [ 15 ] The A330neo's development costs were expected to have an impact of around −0.7% on Airbus's return on sales target from 2015 to 2017, [ 16 ] an estimated ...
