Potential flow theory for fluid and semi-membrane (half bending) theory of shells are used. The shells of finite length are considered for different cases of boundary conditions at the edges of the shell. Arising of the aerodynamic damping in the studied aeroelastic system due to the flowing fluid, and properties of adjoint solution (i.e. the solution corresponded to the opposite orientation of the boundary conditions of the cylinder) are showed. Obtained values of the derivatives of aerodynamic damping (over flow velocity U) in some analytical form are compared with numerical results published before within the used semimembrane theory  of shells and within the 3D shell theory.
