Abstract
A set of structural optimization tools are presented for topology optimization of aircraft wing structures
coupled with Computational Fluid Dynamics (CFD) analyses. The topology optimization tool used for
design is the material distribution technique. Because reducing the weight requires numerous calcula tions, the CFD and structural optimization codes are parallelized and coupled via a code/mesh coupling
scheme. In this study, the algorithms used and the results obtained are presented for topology design of a
wing cross-section under a given critical aerodynamic loading and two different spar positions to deter mine the optimum rib topology.
