Abstract The complex damping influences on the instability characteristics of the panel aero-thermo-elastic system
are theoretically investigated from the energy perspectives. Firstly, by assuming a constant, uniform thermal
loading and adopting the piston theory, the panel aeroelastic governing equation is obtained. After deriving
the panel buckling and vibration modes, the reduced order model can be built and adopted to investigate
the system primary instability in the modal coordinates. Then, introducing the modal damping coefficients
ratio η > 0, the critical parameters of the panel flutter oscillation are theoretically evaluated based on the
on-conservative energy balance principle, thus the system instability characteristics… More >
