COMPUTATIONAL ANALYSIS OF UNMANNED AERIAL VEHICLE WING WITH TRIANGULAR WINGLETS

Computational fluid analysis of an aircraft plays an important role in providing a detailed understanding about the particular aircraft. The qualitative and quantitative characterization of the wings provide the necessary information to check the selection of wings and designing of wings prior to time consuming fabrication of aircraft. Standard wing geometry with Eppler E334 series airfoil has been selected for doing a comparative study with the modified models. The lift, drag and lift to drag ratio for each wing models were determined. The comparative study between the modified wing and base wing clearly shows how minute changes could affect the overall aerodynamic characteristics. The models were designed using CATIA V5 software and simulations were done in ANSYS. The analyses were carried out for velocity 20 m/s and for various angles of attack such as 0, 5, 10, 12, 15 degrees. The wing configuration with winglet shows better aerodynamic performance at high angle of attack when compared with without winglet configuration
