This study investigates the potential of multiple winglets mounted on a transonic wing. The investigation evaluates the reduction of drag coefficient due to presence of multiple winglets on the basic wing model. Numerical Experiments were adopted for these investigations. The commercial CFD solver ANSYS Fluent was used to perform the aerodynamic investigation. Four different models were evaluated based on the configuration. The first model is a non-winglet model, i.e., the base model. The remaining three models were the wings with the multiple winglets, i.e., 60-Winglet model, 75-Winglet model and 90-Winglet model. The differences in the model were based on the cant angle of the winglet. 3D RANS equation along with one equation Spalart-Almaras turbulence model was used for solving the flow past the wing models. The chord wise pressure distribution, pressure variation over the entire wing, coefficient of lift, coefficient of drag, lift to drag ratio were compared for all the cases.
