Winglet on KC-135 Stratotanker with attached tufts showing airflow during NASA tests in 1979–1980 Gulfstream V model winglet flutter tests at NASA Langley transonic wind tunnel. The term "winglet" was previously used to describe an additional lifting surface on an aircraft, like a short section between wheels on fixed undercarriage.
The Spiroid winglet is a closed wing surface attached to the tip of a conventional wing. Wingtip vortices form a major component of wake turbulence and are associated with induced drag, which is a significant contributor to total drag in most regimes. A closed wing avoids the need for wingtips and thus might be expected to reduce wingtip drag ...
Winglets increase the effective aspect ratio of the wing, changing the pattern and magnitude of the vorticity in the vortex pattern. A reduction is achieved in the kinetic energy in the circular air flow, which reduces the amount of fuel expended to perform work upon the spinning air [citation needed].
Winglets have the opposite effect to washout. Winglets allow a greater proportion of lift to be generated near the wing tips. (This can be described as aerodynamic wash-in.) Winglets also promote a greater bending moment at the wing root, possibly necessitating a heavier wing structure
Winglet: a small fin at the wingtip, usually turned upwards. Reduces the size of vortices shed by the wingtip, and hence also tip drag. Strake: a small surface, typically longer than it is wide and mounted on the fuselage. Strakes may be located at various positions in order to improve aerodynamic behaviour.
A winglet is a short fin that projects upward from the wing of an aircraft. They are used to reduce aerodynamic drag. CNBC has requested comment from a spokesman from Trump’s presidential ...
Static wicks on the winglet and aileron of an EasyJet Airbus A319-100. Static wicks, also called static dischargers or static discharge wicks, are devices used to remove static electricity from aircraft in flight. They take the form of small sticks pointing backwards from the wings, and are fitted on almost all civilian aircraft. [1]
