Wing flap deflection control removal

5 A high-lift device surface and associated method of designing the high-lift device surface is described. The flap 308 can be attached to a wing 302 on aircraft 50. The method can involve determining 356 a manufactured shape of the flap. The manufactured flap shape can be deflected in some manner, such as bent or twisted, so that under selected flight conditions, such as cruise, the manufactured flap shape morphs into a second desired shape that satisfies specified 10 constraints, such as geometric and sealing constraints. An advantage of the approach is that the flap doesn't have to be mechanically forced, using mechanical elements, into the second desired shape. The elimination of the mechanical elements results in weight and cost savings to aircraft on which the flap is deployed. Fig. 5A -D ;- ; -o -o C.) -o -o - 0 (5 0 C.) \C Carl Cl 0* Ct -o 0 C.) C.)
