中文摘要：

变体飞机要求机翼结构可以光滑连续地变形。机翼的蒙皮要有足够大的面内伸缩变形能力,同时还要有足够的面外承载能力。本文针对后缘变弯度机翼,设计出一种新的柔性蜂窝结构。研究了该柔性蜂窝的面内变形能力和形状参数的关系。仿真分析和试验验证表明,该柔性蜂窝结构具有足够的面内变形能力,变形后仍保持良好的面外承载能力,满足后缘变弯度机翼的使用要求。

英文摘要：

Morphing aircraft require the airfoil camber to change continuously and smoothly.The flexible skins must have substantial in-plane expansion deformability,while at the same time it must be able to bear the out-of-plane aerodynamic loads.In this article,a new flexible honeycomb structure is designed for the wing with a variable camber trailing edge.The relationship between the in-plane deformability and the shape parameters of the flexible honeycomb are studied.Simulation and experimental studies are carried out for the flexible honeycomb.The results show that the flexible honeycomb has substantial in-plane deformability and maintains good out-of-plane bearing capacity,which satisfies the application requirements of the wing with a variable camber trailing edge.
