The wing is one of the most important parts of an aircraft since it is the part which offers the lift force required to maintain an aircraft in air during flight. This study presents the design of fixed wing for an Unmanned Aerial Vehicle (UAV) of an all up weight of 8kg. The UAV is meant for surveillance purpose. The wing span is considered to be 3m. The wing is designed for a cruise velocity of 15m/s and Reynolds number value of 194446.34. A set of airfoils used in wings of high endurance aircrafts are compared for aerodynamic parameters. The FX 63-137 airfoil is chosen to be the airfoil for designing the wing since this airfoil offers the maximum 〖Cl〗^(3/2)/Cd for the operational conditions considered in comparison to the other airfoils analyzed. The wing so designed is then analyzed for different dihedral angles. The wing with a dihedral angle of 6˚ is found to be having the best aerodynamic performance in terms of offering high endurance out of the set of the wing dihedral variants analyzed.
