Application Status and Future Prospect of Smart Materials and Structures in Morphing Aircraft

Morphing aircraft can alter their shapes to achieve optimal aerodynamic performance under different flight conditions, which will greatly improve the comprehensive performance of the aircraft. Their emergence and development is one of the most important trends of future aircraft. Smart materials and structures have the properties of actuating, morphing, loading, sensing etc., which provide a new technological approach to morphing aircraft design. In this paper, research status is elaborated of smart materials and structures in adaptive structures, smart actuators, and morphing skins. Some key technologies are addressed in detail, such as deformation/loading integrative skins, lightweight high-output actuators, and adaptive structures. The future prospect of the application of smart materials and structures in morphing aircraft is also discussed.
