Abstract

Flight performance of any air vehicle depends on the shape of the airfoils and wings. Observing the natural fliers, it is observed that albatrosses have one of the best flight performances. These birds can soar thousands of kilometers, without spending much of their own energy. This study investigates the effect of albatross wing airfoil on the aerodynamic performance. The aerodynamic performance analysis is undertaken by taking similar geometry and Reynolds number. In this work first different airfoils like E420, 421, 422, 423 and Gottingen airfoils GOE 174 and 176 were studied. The coordinates of the airfoils were extracted from the existing work of UIUC database and simulated by XFLR- 5. Planform of four models of wings namely Albatross 01, Albatross 02, Delta wing and Rectangular wings were modeled. Flow simulation was done in XFLR-5. The coefficient of lift, coefficient of drag and ratio of the coefficient of lift and drag verses angles of attack were obtained at Reynolds number 100000. The result demonstrated that the lift coefficient of Airfoil E423 was best in E series airfoils and when compared with GOE 176 airfoil, it’s found that this airfoil is much superior to E423. The aerodynamic performance (CL/CD) of the Albatross 02 wing was found much superior than Delta, Rectangular and Albatross 01 wing. These airfoils results showed that the GOE 174 can be used for cruise and glide performance and GOE 176 airfoil could be used for takeoff, landing and maneuvering performance.
