Three-dimensional Elastic Structure for Aerospace Applications

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
