A REPORT ON NUMERICAL INVESTIGATION OF WINGS: WITH AND WITHOUT WINGLET

The main goal of the proposed paper is the numerical investigation of Wings with and without winglet designs. Thisinvestigation shows the various performance and parameters for the wings when designed with a winglet and without awinglet and thus comparing the parameters for both the designs. The discussions were focused on the aerodynamicscharacteristics which include drag coefficient CD, lift coefficient CL, and lift-to-drag ratio L/D. In this investigation twoDifferent wings are used: An Elliptical wing and a Short wing. The airfoil used in this investigation is NACA 2412 withwhich both the wings are designed. The Geometry of the models is carried out in the CATIA V5 R19 Software and isdesigned in Part and Wireframe and Surface Design. The airfoils of Different Chord length are designed with differentStations using the geometry given in the DESIGNFOIL Software. The winglet is then designed for both the wings. Theinvestigation aims to produce better aerodynamic performance with the implementation of the winglet for both wingdesigns. One of the objectives of this work is reduce the induced drag formed on wing during the fight operation, thusimproving the efficiency of the aircraft. The analysis part is done by using the ANSYS Software, flow parameters (like thelift and drag) are measured for different design configurations and are compared with the plane wing and the wing designedwith winglet.
