Abstract
A promising mathematical model is considered for studying the aeroelastic stability of sandwich shells supported by an internal hollow elastic cylinder and annular ribs. Using the relations derived, the influence of thickness of the inner hollow cylinder, the length of the shell, and the shear modulus of core on the critical air flow speed leading to the occurrence of flutter was studied. Based on the calculations performed, recommendations were developed for choosing parameters of the sandwich composite structure considered. The mathematical model presented makes it possible to expand the range of topical scientific and applied problems that can be solved in the field of aeroelastic stability of sandwich shells.
