Winglets are angled extensions or vertical projections at the tip of a wing, they are widely used in conjunction with plain airfoils on commercial airplanes for the purpose of reducing induced drag, vortices, and increasing lift. In this paper parabolic shaped configuration winglets at cant angles 45 and 55 degrees are analyzed on rectangular NACA 2412 airfoil sections using CFD analysis at Reynolds number 2*105 and 4*105 to compare aerodynamic characteristics. The wing is of 6 inch chord and 12 inches span, airfoils have been created using CATIA V5 and CFD analysis has been carried out using commercial code software ANSYS FLUENT 14.0, it is found that the L/D ratio increases by 13.447% and the coefficient of lift (CL) increases by 1.958% for a parabolic winglet at 45 degrees cant angle at 2*105 Reynolds number causing a maximum reduction in coefficient of drag (CD) by 10.125% and thereby reducing fuel consumption of the aircraft.
