Level set topology optimisation of aircraft wing considering aerostructural interaction

Topology optimisation is the most general form of structural optimisation, capable of calculating the optimal arrangement of material in a loaded structure. Low weight efficient structures are vital to aircraft performance making aerospace structures an ideal field for the application of topology optimisation. In this investigation 3D level set topology optimisation is developed to optimise the internal structure of an aircraft wing with coupled aerostructural interaction. The results suggest that an alternative configuration of I-beam like wing with columns may be an optimal solution for wing structures. They also show the importance of considering the relationship between the internal wing structure and its aerodynamic performance. The paper thus, demonstrates potential benefits of Aerostructural 3D level set topology optimisation for a design of aircraft wing.
