In this paper, the wing box of an aircraft is optimized using a level set topology optimization method and considering aerostructural coupling. A new level set method is developed where the design domain and the finite element analysis domain are represented by two separate meshes, and coordinates and sensitivities are transformed from one mesh to the other mesh using an isoparametric map. This method is applied to minimize the compliance and tip displacement of a tapered and swept wing box subjected to aerodynamic loads. The wing box is modeled using 1.47 million isoparametric hexahedral elements, whereas the skin (which is nondesignable) is modeled using shell elements. The results show that the optimizer exploits the aerostructural coupling properties and tailors the lift distribution to yield stiffer wing boxes. Moreover, the results also show that ignoring aerostructural coupling leads to suboptimal designs.
