柔性变形翼结构设计、建模与分析研究进展OA

The design of future aircraft will face severe challenges such as the continuous expansion of airspace domain and the speed domain,and the increasing requirements for the mission adaptability.The morphing aircraft can provide new ideas and methods for improving the flight performance and expanding the flight envelope.The use of the flexible skin combined with corresponding support structures has become the main solution to overcome the shortcomings of traditional morphing aircrafts.Firstly,the status of the research of flexible skin,honeycomb support structure,and other new smart material in the morphing aircraft design is reviewed.Then,the design,modeling and analysis methods of the flexible deformable wing structures in the existing literature are discussed.Finally,the existing problems in the modeling and analysis methods of flexible deformable wing structures and possible future research directions are proposed.
