Abstract

Wingtip vortices are strongly associated with induced drag for a three-dimensional wing. So it is important to neglect the wingtip vortices in order to reduce the induced drag. The drag breakdown of a typical transport aircraft shows that the lift-induced drag can amount to as much as 40% of the total drag at cruise conditions and 80– 90% of the total drag in take-off configuration. One way of reducing lift-induced drag is by using wingtip devices. By applying biomimetic abstraction of the principle behind a bird’s wingtip feathers, we study spiroid wingtips, which look like an extended blended wingtip that bends upward by 360 degrees to form a large rigid ribbon.In this paper a configuration of different winglets are studied. A model composed of wing of boeing-737 is designed using CATIA and also the spiroid winglet are designed and attached with a boeing 737 wing using CATIA. Then the modelled wing is meshed using ICEM-CFD. The meshed model will be analysed using ANSYS FLUENT. Finally the percentage decrement of wingtip vortices is calculated using the analysis results.
