CFD Analysis and Comparision of Spiroid and Dual Feather Winglets

Potential of spiroid and dual feather winglet's are taken into consideration. By using biomimetic abstraction principle of a bird's wingtip feathers, we study spiroid and dual feather winglets which look like extended blended winglets. The dual feather winglets is the study about of advance hybrid winglets design. Considering NACA 2412 airfoil, the wing and winglets have been generated of wing span 28350 mm and wing chord 7320 mm which is the specification of BOEING 737. The purpose of the analysis is to examine aerodynamic characteristics and to scrutinize the performance of winglets at different Angle of Attacks (0, 10, and 15). The CFD simulations are performed. The winglet model is designed using CATIA V5 software. Computational simulation is carried out by FLUENT. The aerodynamic characteristics of the designed winglets are compared.
