Wingtip device - Wikipedia
网页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.
This Is How Winglets Work - Boldmethod
网页2022年3月12日 · Winglets oppose the drag wingtip vortices create by harnessing the vortices' airflow. NASA engineer Richard Whitcomb pioneered the technology in the 1970s, and they've become a fixture on almost every modern jet. So how do they work? First, you need to understand how wingtip vortices form and why they create drag.
Winglets | Glenn Research Center | NASA
网页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 be more two-dimensional.
What are the types of aircraft winglets and how do they work?
网页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.

网页翼梢小翼（Winglet)，类似于 机翼 翼面的小机翼，近似垂直于机翼翼面，由美国国家航空航天局（NASA） 艾姆斯研究中心 的R.T.惠特科姆 (R.T.Whitcomb）于上世纪80年代发明。. 在飞行中，机翼下翼面的高压区气流会绕过翼梢流向上翼面，形成强烈的旋涡气流，并从 ...
How Things Work: Winglets | Smithsonian
网页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...
What Are The Different Kinds Of Winglets? - Simple Flying
网页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.
翼尖小翼 - 维基百科，自由的百科全书
网页翼尖小翼 （winglet），又稱作 翼梢小翼 、 翼尖帆 或 翼端帆，通常用于提高固定翼 航空器 机翼 的效率，也可用来改善航空器的操纵特性。 原理. 飛機維持正常飛行時所需的升力是靠機翼上下表面的壓力差產生的，由於上下表面壓差的存在，翼尖附近機翼下表面空氣會繞流到上表面，形成 翼尖渦流，致使翼尖附近區域機翼上下表面的壓差降低，從而導致這一區域產生的升力降低。 為了削弱這種繞流現象對升力的影響，很多飛機的翼尖都安裝了翼尖小 …
