Design and CFD Analysis of Parametric Winglets

Abstract

Computational Fluid Dynamic analysis of winglets has been shown in this journal. First the wing model is designed using CATIA V5 and its meshing is done using Gambit and finally its analysis is done in FLUENT. When the aircraft moves through the air, it results into the production of wingtip vortices due to its own lifting. These wingtip vortices are higher as the aircraft lift increases. If winglets are fixed to wingtips, then such wingtip vortex goes down and the aircraft performance will turn out to be better. We have hardly emphasized on the analyses and wingtip vortex development and performance. When winglets are used, drag coefficient decreases since wingtip vortices are broken or reduced by winglets. The drag coefficient reduction and why it is reduced will be the main aim to study and develop in my project. Finally, we would like to demonstrate and prove winglet works more efficiently and, in addition, to show how drag coefficient can be reduced. That is the main reason why aircraft’s fuel efficiency can be improved if winglets are linked to wingtips.
