Abstract

The winglet reduces the induced drag at the wing tips and increases the lift to drag ratio. Wingtip devices are usually intended to improve the efficiency of fixed-wing aircraft. The winglet also reduces the fuel usage and increases the single engine performance. This paper deals with Analysis of reducing the induced drag using winglet at the wingtip. We have considered the Boeing 767 wing and attached the winglet to analyze the performance. Winglets are mounted on the wing tips as the vertical extensions. The comparisons were done to see the performance of winglet at different angles of attack. Wing and winglet are designed in Catia V5 then analyzed in Ansys CFX workbench and Fluent to reduce the vortices at the wingtips.
