Study on Wing Layout Design of Aircraft

This paper describes how the wing surfaces are defined by aerodynamic, stability/control, layout and structural requirements. The size of the wing (area) will usually be dictated by aircraft performance requirements(e.g. field length) but the shape of the planform and other geometry may be influenced by wing layout factors. In the early design stages choices need to be made on the position of the wing relative to the fuselage (e.g. high, mid or low position) and then on the overall envelope. This will include selection of aspect ratio, taper ratio, sweepback angle, thickness ratio and section profile, and dihedral. Each of these decisions is explained. A brief introduction on flap design of the aerodynamic (lift and drag) characteristics of flaps are also described, which is added to explain the wing layout of aircraft.
