Multidisciplinary Design Optimization Framework for Morphing Wing using Metamaterials

Abstract

Metamaterials introduce innovative possibilities for morphing wing design. This paper explores two methods of incorporating metamaterials into morphing wing design and applies a Multidisciplinary Design Optimization process to optimize and compare this design against a conventional composite wing. The analysis integrates aerodynamic, structural, and control considerations to evaluate the effectiveness of the metamaterial applications. The two approaches involve a variable-stiffness leading edge surface, and a trailing edge equipped with a metamaterial lattice hinge for smooth deformation. The paper presents the Multidisciplinary Design Optimization framework and initial findings from individual analyses, linking two-dimensional aero-structural wing rib design with surrogate models that extend to three-dimensional aerodynamic and control evaluations.
