Topology Optimization of Aeroelastically Scaled Wing Models based on Additive Manufacturing

ifasd2024 Tracking Number 237

The objective of this paper is to explore aeroelastic scaling methodologies that can be used to create 3D printable prototypes for wind tunnel testing. This would reduce testing costs and allow for the study of aeroelastic phenomena, including nonlinear effects such as the impact of large deformations on classical bending-torsion flutter. To achieve this goal, we plan to investigate various scaling laws based on the design requirements of both the available additive manufacturing techniques and wind tunnel. In addition to this task, we will develop aeroelastic scaling strategies based on these laws. These strategies will combine aerodynamic similitude by maintaining the outer mold line of the full-size model while tailoring the internal structure using a mix of topology optimization and sizing. The internal structure can be tailored to integrate sensors and actuators, while topology optimization can achieve structural dynamics similitude. The subject of the study is the X-56 aircraft.
