Wingtip devices are intended to improve the efficiency of fixed-wing aircraft by reducing drag. [1] . Although there are several types of wing tip devices which function in different manners, their intended effect is always to reduce an aircraft's drag.

2023年11月2日 · Winglets were wind tunnel tested and computer analyzed by Richard Whitcomb of the NASA Langley Research Center in the mid 1970’s. The idea behind the winglet is to reduce the strength of the tip vortex and therefore cause the flow across the wing to …

2022年3月12日 · What does a winglet do, besides make an airplane look cool? They're known to increase performance, increasing range and decreasing fuel burn, but why? Winglets oppose the drag wingtip vortices create by harnessing the vortices' airflow.

2023年6月1日 · Winglets are essentially aerodynamic performance enhancers. Their primary purpose is to improve aircraft performance by reducing aerodynamic drag. Drag degrades the aircraft’s performance, especially at high speeds and high altitudes where commercial airliners spend most of their time.

2023年9月6日 · Winglets are vertical extensions of wingtips that improve fuel efficiency and cruising range by reducing drag caused by vortices. The most popular types of winglets in commercial aviation are canted, blended, split-scimitar, and sharklets. Each type of winglet has its own specific design and benefits, with some being more efficient than others.

3 天之前 · Airbus introduced its own refined winglet design, called a sharklet, in 2011. In addition to raked wingtips, Boeing also employs split-scimitar winglets, which can be found on the 737 MAX.

The new 737 MAX AT winglet is the most efficient ever designed for a production airplane. This is the story of the ingenious manipulation of aerodynamics that makes this distinctive design so efficient.

Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper surface of an airplane's wing and that on the lower surface. High pressure on the...

2019年12月9日 · The ad is on the upward sloping mini-wing on the tip of the wing, called a winglet. The tips of airplane wings are adorned with all manner of winglets, sometimes featuring a distinct curve, like the Airbus A350 or Boeing 787.

Winglets are vertical or angled extensions at the tips of an airplane’s wings. They are designed to improve the efficiency of the wing by reducing aerodynamic drag caused by wingtip vortices.
