This work focuses on the layerwise finite element modelling and active aeroelastic flutter control of smart variable stiffness laminated composite panels with surface bonded piezoelectric layers/patches under supersonic airflow. The proposed aero-electro-elastic models make use First- Third-order Shear Deformation Theories, along a linear through-thickness distribution electric potential, whereas effect airflow is described by First-order Piston Theory. Numerical applications simply supported either curvilinear or unidirectional fibres are provided for accuracy assessment predictive capabilities, considering various side-to-thickness ratios conditions. proportional response discussed both x-axis yawed airflow, in addition to three different placement configurations patches.
