Multiple flight regimes during typical aircraft missions mean that a single unique optimized configuration, maximizes aerodynamic efficiency and maneuverability, cannot be defined. Discrete components such as ailerons flaps provide some adaptability, although they are far from optimal. Wing morphing can significantly improve the performance of future aircraft, by adapting wing shape to specific regime requirements, but also represents challenging problem: structure has stiff maintain its...

Aircraft wings are usually optimized for a specific design point. However, since they operate in wide variety of flight regimes, some these have conflicting impacts on aircraft process, as single configuration may be efficient one instance but perform poorly others. In principle, stiff, hardly deformable structures preclude any adaptation to changing conditions. Alternatively, morphing could provide adaptive capabilities maximize performance operation.
