AbstractAerodynamic efficiency is defined as a ratio of co-efficient of lift to co-efficient of drag. Reduction of aerodynamic efficiency is a result of wing tip vortices which attributes to induced drag. These vortices are formed due to the difference in pressure between the top and bottom surfaces of the wing. Winglets can be used to improve overall aerodynamic efficiency of a wing. In this study, we will compare the effect of different configurations of winglets – Canted, Fenced, Raked and Spiroid on the aerodynamic efficiency of the wing. A GOE767-il aerofoil wing made of aluminium is modelled and retro-fitted with the above mentioned winglet configurations. CFD analysis for the wing and winglets will be done in three flight conditions – Take-off, Cruise and Landing, to calculate co-efficient of lift and drag. This computational analysis will be done on Ansys Fluent using Spalart – Allmaras turbulence model. The CFD results obtained will be compared based on the efficiency to determine the best winglet configuration for said aerofoil structure and wing parameters.
