Thermoelastic stability of closed cylindrical shell in supersonic gas flow

In this paper the wand-massagers problem of linear stability of a closed cylindrical shell under the action of both non-uniform temperature field and supersonic gas flow is considered.The stability conditions for the unperturbed state of the aerothermoelastic system are obtained.It is shown that, by the combined action of the temperature field and the ambient supersonic flow, the process of linear stability can be controlled and the temperature field LUTEIN affects significantly the critical flutter speed.Keywords: Cylindrical shell, Supersonic gas flow, Thermal field.
