Analysis of Wing (NACA 0012 Aero foil) with and without Winglets to Enhance Aerodynamic Efficiency

Parameshwar Banakar*

Aerodynamic drag can be reduced by modifying a wing’s geometry and the wingtip design. Winglets play a vital role in the wing design. The winglets present at the tip of wings helps in reducing the drag and that results in increase of lift to drag ratio. This work deals with the analysis of winglet at the tip of wing to reduce the induced drag in order to enhance the aerodynamic efficiency. Considering the NACA 0012 airfoil for the rectangular wing and two types of winglets i.e., wing grid, blended wing so as to analyze performance of each. The focus is to study the lift and drag forces generated by merging winglet design with the constrained aircraft wing. The wing and wing with winglets are constructed in the solid works software and the same has been analysed in the ANSYS fluent workbench. The effects on lift and drag of the wing can be obtained using computational fluid dynamics considering the contribution of aerodynamic forces and winglets. At last, the efficiency of wing was further determined by evaluating lift to drag ratio with obtained lift and drag forces and the comparison was made between the winglets used based on its performance and contribution to the enhancement of the aerodynamic efficiency.
