Wingtip device - Wikipedia
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.
Winglets | Glenn Research Center | NASA
Nov 2, 2023 · 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 …
翼梢小翼 - 百度百科
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 ...

What are the types of aircraft winglets and how do they work?
Jun 1, 2023 · What do winglets do? 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.
This Is How Winglets Work - Boldmethod
Mar 12, 2022 · 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.
How Things Work: Winglets | Smithsonian
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...
Winglets: a tip-top solution for more efficient aircraft - Airbus
When the first A330neo (New Engine Option) jetliner takes to the skies this year, it will mark the latest use of Airbus’ Sharklets™ – those graceful-looking upturned wingtip extensions that save fuel by reducing drag while also lowering noise emissions by improving take-off performance.
Optimum Induced Drag of Wingtip Devices: The Concept of Best Winglet …
Mar 1, 2022 · 9 Proposed New Winglet Designs. The primary properties and the related discussions and validations, suggest that a very effective form of a reduction of induced drag is the adoption of the Box Winglet, which is the Best Winglet Design from a pure induced drag perspective only.
Variable cant angle winglets for improvement of aircraft flight ...
Sep 9, 2020 · By using computational fluid dynamics, we study the influence of the winglet cant angle and sweep angle on the performance of a benchmark wing at Mach numbers of 0.3 and 0.8395. The results obtained demonstrate that by adjusting the cant angle, the aerodynamic performance can be improved at different flight conditions.
