Active Aeroelastic Control over a Multi-Surface Wing: Modelling and Wind Tunnel Testing

This paper presents the work that has been performed on a wind tunnel aeroelastic wing model to implement a multi-surface modal control. Wing model realization, control system and experimental setup will be here described briefly, together with a methodology used to tune numerically the simple control system. Usage of multiple wind tunnel test session has been adopted firstly to perform numerical-experimental correlations and then to optimize control parameters. The entire control system shows off capability to damp wing bending and torsion mode, within model flight envelope, still remaining stable.
