In this research, the free vibration and supersonic flutter analyses of a cylindrical sandwich shell with reinforced honeycomb core (RHC) integrated piezoelectric face sheets are investigated. The is structure enriched fibers carbon nanotubes (CNTs). layers modeled based on Cooper-Naghdi theory continuity conditions between considered. aerodynamic pressure flow using linear piston theory. Hamilton's principle used to derive governing equations. A semi-analytical solution presented including an exact in circumferential direction followed by numerical longitudinal via differential quadrature method (DQM). effects several parameters frequencies, corresponding damping coefficients, critical It concluded that improving stiffness CNTs does not necessarily improve aeroelastic stability shell. results can be design analysis aerospace structures.
