Research status and key technologies of in-plane deformation of morphing wing surface

Abstract

Morphing wing is one of the important development directions of future aircraft design, and the study of in-plane deformation of the morphing wing surface has received widespread attention. In this paper, four aspects in-cluding variable span length, variable sweep angle, variable chord length and combined deformation are analyzed to describe the current status of domestic and international research on in-plane morphing wings, summarize the defor-mation mechanism and its advantages and disadvantages, and analyze the future development trend of morphing wing. In view of the current research situation and the application requirements of the morphing wing, the key tech-nologies of the morphing wing are proposed, including the morphing skin technology, morphing mechanism, intelli-gent actuator, sensor and control network. The application requirements of each key technology and the existing problems are analyzed furthermore. The future development direction is summarized, which can provide some references for the design and application realization of in-plane morphing wings.
