多模态变构超材料变形机翼设计与验证
Design and verification of metamaterial morphing wings with multi-modal morphing capacity
摘要
Abstract
As a revolutionary paradigm of the next generation of aircraft,morphing aircraft features the real-time aero-dynamic shape reconstruction capability,which can break through the limitation of aerodynamic efficiency and mission adaptability of traditional fixed-wing aircraft.In order to solve the issue of limited morphing freedom and difficulty in achieving distributed continuous deformation of the mechanical metamaterial wings,this paper proposes a multi-modal morphing wing design scheme based on heterogeneous mechanical metamaterials.Firstly,by constructing a basic unit-cell system with gradient mechanical properties,combined with the sequential design of rigid load-bearing unit-cell and flexible deforming unit-cell,the coordinated control of structural lightweight and large morphing capacity is real-ized.Secondly,the active actuating unit-cell and the transition unit-cell element are further developed,and the para-metric space arrangement strategy for the aerodynamic contour was established to form a full-lattice wing structure with multi-modal collaborative morphing capacity.Finally,based on finite element simulation and morphing function experi-ment,the overall torsion and local thickness adjustment capacity of the wing surface are verified.The results show that the proposed gradient metamaterial wing can achieve continuous torsional deformation of 12°/-9° in the spanwise direction and thickness adjustment of 8%in the chordwise direction.The research results provide a new way to break through the optimization of cross-domain aerodynamic performance and multi-task adaptive control of aircraft,and have important engineering value for the development of intelligent morphing aircraft.关键词
