Winglets reduce wingtip vortices, the twin tornados formed by the difference between the pressure on the upper and lower surfaces of an aircraft's wing. High pressure on the lower surface creates a natural airflow that makes its way to the wingtip and curls around it.
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. This allows optimum aerodynamic loading and avoids vortex concentrations that produce drag.
Highly Blended Winglets have demonstrated more than 60 percent greater effectiveness over the similar sized conventional winglets with an angular transition. By reducing drag, Blended Winglets increase fuel efficiency and boost range.
Blended Winglets enhance longitudinal and directional stability, thereby providing better handling in turbulent atmospheric conditions.
