跨域飞行器结构与变构型设计技术进展与挑战
Advances and challenges in cross-domain vehicle structures and morphing configuration design technologies
摘要
Abstract
By the virtue of its design orientation of"multi-functionality"and efficient repeated flights in large airspace and wide speed range,the cross-domain vehicle is of epoch-making significance in the field of aerospace and is be-coming one of the focuses of technological competition among various countries.Due to the high frontier and compre-hensive nature of this field,there is no clear technical route to realize the large envelope cross-domain vehicle,but it is generally agreed that the morphing configuration is the key technology and necessary means.In this paper,we dis-cuss the conceptual routes to achieve cross-domain vehicle from four aspects,namely,the basic configuration,the morphing mode,the optimization of the morphing structure,and the thermal protection,with the morphing configura-tion as the main theme.We analyze the technology pavements and reference values provided by the existing re-searches on the design of cross-domain vehicle,and summarize the respective technological advances and chal-lenges.Firstly,several basic configurations with application potential are introduced,and the differences in aerody-namic performance and volumetric ratio are compared;secondly,the structural design and aerodynamic impacts of different schemes are analyzed according to the classification of wings and head-cones;then,three levels of structural optimization techniques,passive and active thermal protection structural designs are introduced from the perspective of improving the deformation,load-bearing,and thermal protection performance of the morphing structures;finally,we summarize the challenges and problems that are still facing in the work of cross-domain vehicle structures and mor-phing configuration design,and look forward to the future development direction of related research.关键词
