The objective of this paper is to present an aeroelastic scaling framework that can be used to create 3D printable prototypes for wind tunnel testing. This would enable the study
of aeroelastic phenomena, including nonlinear effects such as the impact of large deformations on classical bending-torsion flutter at a reduced development cost. To this end, an investigation of various scaling laws based on topology optimisation techniques and additive manufacturing constraints to produce scaled wind tunnel models is presented. Additionally, aeroelastic scaling strategies combining aerodynamic similitude by maintaining the outer mould line of the full-size model while tailoring the internal structure using a mix of topology optimisation and sizing are presented. The internal structure can be tailored to integrate sensors and actuators, while the topology optimisation can achieve dynamic similitude. The subject of the case study is the X-56 aircraft.
