Structural Optimization of 3D Wings Under Aerodynamic Loads: Topology and Shell

摘要

New methods in manufacturing and novel challenges and usages require the exploration of the potential of new wing designs. This is the goal of this paper. We propose novel computational methods for the robust optimization of wings under aerodynamic loads. We restrict the discussion to the optimization of the linear-elastic properties of wings concerning several load cases and with treatment on deformations and regularization. The degrees of freedom for the design itself are the interior structure of the wing leading to topology optimization aspects and the structure of the wing hull in terms of composite material. Thus, this paper aims at mathematical methods for topology optimization of the wing interior made of isotropic material, the optimization of orthotropic composite material in the wing hull and the proper treatment of practical deformation aspects and multiple loads in this context.
