Numerical Investigation of Winglets Used To Improve the Flying Performance of Unmanned Aerial Vehicle

Abstract

In this study, the aerodynamic forces, velocity and pressure distributions are analyzed on SD7062 wing profile with CFD program FLUENT. Calculations are made for one clean wing and 3 different winglets named End-Plate, Blended and Scimitar which are added on this clean wing. Each model are analyzed for different angle of attack degrees between -5 and 17. After calculations were ended, it is seen that wings’ with winglets aerodynamic performances are increased. Additionally, stall was occurred around 15 aoa degrees. © 2016 9th International Conference on Computational Fluid Dynamics, ICCFD 2016 - Proceedings. All rights reserved.
