A method of designing an external geometry of an aircraft lifting surface, including the steps of defining a geometric shape corresponding to an initial lifting surface according to a planform, wherein the initial lifting surface is defined by at least five geometry parameters and a plurality of shape modifier parameters of the lifting surface, modifying the geometric shape of the initial lifting surface by applying a spanwise function to a shape modifier parameter of the initial lifting surface to obtain a modified lifting surface, defining a thickness of an airfoil at a given span position along the span of the modified lifting surface obtained in the modifying step based on a predefined airfoil, and defining the external geometry of the aircraft final lifting surface by interpolating the airfoil along the span of the modified lifting surface via a transition function.
