The Blended Winglet has a large radius and is designed with a smooth chord variation in the transition area where the wing joins the winglet. This allows optimum aerodynamic loading and avoids vortex concentrations that produce drag.

With the original blended winglet design, the airflow at the tip is used to create lift on the winglet, primarily vectored toward the fuselage. There is also a small element of lift vectored forward, reducing the lift-induced drag. Both these elements improve the efficiency of the wing.

A blended winglet is attached to the wing with a smooth curve instead of a sharp angle and is intended to reduce interference drag at the wing/winglet junction. A sharp interior angle in this region can interact with the boundary layer flow causing a drag inducing vortex, negating some of the benefit of the winglet.

Sep 6, 2023 · 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.

Our Blended Winglet geometry is the best in the air, designed to achieve near ideal flow. Blended Winglets reduce wingtip vortex, resulting in less drag, lower fuel burn and superior climb and cruise characteristics. You'll go farther and get there faster.

Jun 1, 2023 · Blended winglets are the most common type of winglets in service today. They are curved gently outwards at the end of the wings and blend seamlessly into the wings themselves. First developed by Gulfstream in the 1990s, the blended …

Aviation Partners Boeing are Leaders in Advanced Blended Winglet Technology. Blended Winglets provide a simple and elegant solution to measurably improving aircraft fuel burn, managing operating costs and extending the economic life of an aircraft.

Aviation Partners' Blended Winglets feature a high aspect ratio for lower cruise drag while maintaining buffet margins and favorable low-speed characteristics. The Blended Winglet incorporates a large radius and a smooth chord variation in the wing-to-winglet transition area.

Mar 4, 2025 · The present study conducted CFD simulations on a blended wing body (BWB) with five different winglet configurations to assess their impact on aerodynamic performance. The UCAV 1303 model serves as the BWB simulation model, with winglets attached at the wingtips. The simulation results reveal that downward-blended winglets exhibit superior aerodynamic …

Basically five types of winglets exists, A blended winglet as shown in Figure 1 is attached to the wing with smooth curve instead of a sharp angle and is intended to reduce interference drag at the wing/winglet junction.
