In this paper the aero-thermo-elastic response of layered panels including the effects of viscoelastic materials is investigated. The structural models has been developed in the frameworks of the Carrera Unified Formulation that allows refined kinematics models to be derived without any ad hoc formulation. The aerodynamic forces have been evaluated by means of the piston theory that is only supersonic regimes have been considered. The aero-thermo-elastic model has been assessed and the effects of the viscoelastic material on the aeroelastic response have been evaluated. The results show that use of an advanced kinematics approximation leads to accurate results also when complex multi-layered panels are considered. The introduction of viscoelastic materials is able to modify the response of the panel and can be used to modify the range in which the aeroelastic instabilities appear.
