To assess the structural potential of strut-braced dry wings, an optimization method is presented combining topology optimization of the wing and strut volumes with composite layup optimization of skins and spars. The goal is to identify novel load paths and evaluate mass within an aircraft design framework for a hydrogen-powered aircraft, benchmarking against a classical rib-stiffened wing.
