Abstract

This paper shows fluid structure interaction simulations of a highly flexible wing at various flow conditions, including flutter regime. This is achieved with two-way time domain coupling of a geometrically exact beam structural model and a 3D free wake panel method, modelling the outer surface of the wing, which allow for non-linear effects of the geometry deformation and the flow to be taken into account. Static and aeroelastic wing deflections are compared to experimental data of the Pazy wing with good accuracy. Two regions of flutter onset are predicted within the experimental range. An analysis of the flutter modes is performed. This serves as a step towards mid-fidelity simulations for more complex configurations, including fuselage effects and tail interactions.
