Abstract
This paper represents the design and analysis of the bird inspired multi blended winglets for reducing the induced drag. In order to reduce the induced drag a device called winglet which is mounted at the tip of the wing. Different types of winglets have reduced the induced drag in different flights this represents the influences of the winglets in the reduction of induced drag is the most possible ways. The designed winglets provides an optimum reduction in the drag that created by the trailing vortices at the aircraft wing tip. It consists of analysing of winglet for several angles of attack to determine the coefficient of lift and drag. The values is then compared with the regular blended winglets and plot CL and CD for both wings. This winglet design will reduce the fuel consumption and make the aircraft more stable and also give the life of engine by reducing the drag. The winglet are modelled using CATIA VSR 20, the meshing is done by using TCEM CFD meshing and CFD analysis is done by using ANSYS fluent. The turbulence model used for analysis is Spalart-Allmaras. and solver is coupled solver using higher order differential terms. This software plays an important role in time to make the design, simulation and also the testing of model.
