Morphing wings have become one of the important development directions of designing aircraft, and the field has received extensive attention. In this paper, the current status of research at home and abroad was explained, the deformation mechanism was summarised and the development trend was analysed from four aspects: variable span, variable sweep angle, variable chord length and combined deformation. According to the research status in this field and the application requirements of deformable wings, this paper proposed the key technologies to be solved urgently for morphing wings, including deformable skin technology, deformation mechanism, intelligent driver, sensor and control network. It was expected to provide a partial reference for the design and application implementation of deformable wings.
