摘　　要：本文提出基于三维弹性结构的变形飞机设计构想。三维弹性结构可以构成未来作战飞机的主体零件,能实现金属零件减重,大体积变形并保证性能不变。分别阐述了三维弹性结构组成部分中的三棱锥变形结构和等强空心变形结构的概念和机理,进而引出三维弹性结构零件的特点。通过与现有变形飞机的技术和材料进行对比,描述了以三维弹性结构为主体的作战飞机的设计思路以及对未来的作战方式的影响。In this paper, a morphing aircraft design idea based on three-dimensional elastic structure was proposed. The three-dimensional elastic structure can be main parts of combat aircraft in the future, which can lose the metal parts weight, achieve large volume deformation and keep on performance guarantee. It also characterized the concept and morphing principle of triangular pyramid morphing structure and hollow constant-strength morphing structure, which were important part of three-dimensional elastic structure, and then shown the feature of three-dimensional elastic parts. By comparison of the three-dimensional elastic morphing aircraft, described the design of the new aircraft with the battle model for in the future. structure and the present technology and materials of three-dimensional elastic structure and the influence for
