Aerostructural topology optimization using high fidelity modeling

Abstract We investigate the use of density-based topology optimization for aeroelastic design very flexible wings. This is achieved with a Reynolds-averaged Navier–Stokes finite volume solver, coupled to geometrically nonlinear element structural simulate large-displacement fluid-structure interaction. A gradient-based approach used derivatives obtained via adjoint solver based on algorithmic differentiation. In example problem, uses strong coupling effects and internal wing allow mass reduction while maintaining lift. also propose method accelerate convergence discrete topologies, which partially mitigates computational expense high-fidelity modeling approaches.
