Abstract
In connection with the promising use of sandwich shells in the designs of modern technology and primarily in aircraft, the methodology of building models for studying the aeroelastic stability of sandwich shells reinforced with annular ribs and an internal hollow cylinder is considered. Equations are obtained and the main stages of solving the problem using the proposed set of methods are considered. Dependencies were constructed with the help of which the influence of the thickness of the reinforcing cylinder, the number of annular ribs and the length of the shell on the critical speed of flow was studied. The considered methodology makes it possible to construct an initial approximation model for studying the aeroelastic stability of reinforced sandwich shells.
