    Parallelized Structural Topology Optimization and Cfd Coupling for Design of Aircraft Wing Structures
    (Pergamon-elsevier Science Ltd, 2011) Oktay, E.; Akay, H. U.; Merttopcuoglu, O.
    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 calculations, 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 determine the optimum rib topology.

    Three-Dimensional Structural Topology Optimization of Aerial Vehicles Under Aerodynamic Loads
    (Pergamon-elsevier Science Ltd, 2014) Oktay, Erdal; Akay, Hasan Umur; Akay, Hasan U.; Sehitoglu, Onur T.; Akay, Hasan Umur; Automotive Engineering; Automotive Engineering
    A previously developed density distribution-based structural topology optimization algorithm coupled with a Computational Fluid Dynamics (CFD) solver for aerodynamic force predictions is extended to solve large-scale problems to reveal inner structural details of a wing wholly rather than some specific regions. Resorting to an iterative conjugate gradient algorithm for the solution of the structural equilibrium equations needed at each step of the topology optimizations allowed the solution of larger size problems, which could not be handled previously with a direct equation solver. Both the topology optimization and CFD codes are parallelized to obtain faster solutions. Because of the complexity of the computed aerodynamic loads, a case study involving optimization of the inner structure of the wing of an unmanned aerial vehicle (UAV) led to topologies, which could not be obtained by intuition alone. Post-processing features specifically tailored for visualizing computed topologies proved to be good design tools in the hands of designers for identifying complex structural components.
