This paper presents the results of determining the free oscillation frequency of a structurally anisotropic, cylindrical fiberglass shell reinforced by annular ribs and containing fluid flow. Boundary Navier conditions are imposed on the ends of the shell. Natural oscillation frequencies are calculated as functions of the frequency on the fiberglass winding angle and liquid flow rate for different valuesof of wave parameters and the parameters characterizing the geometric dimensions of the shell.
