Stability of elastic elements of thin-shelled constructions under aerohydrodynamic action

Dynamic stability of elastic elements of thin-shelled constructions under interaction with flow of fluid or gas is studied. Subsonic regime is considered. Aerodynamic load is determined by asymptotic aerohydromechanics equations.
Statements and investigation methods offered for dynamical damping elastic bodies, being in contact with subsonic flow of the fluid or the gas, lead to the study of linked initial boundary problems to systems of partial differential equations. Being based on the construction of functionals, corresponding to these systems, solutions' stability conditions are obtained for some aerohydroelastical problems, in particular for dynamics of elements of a plane channel, through which fluid flows; elements of profile of a wing; pipeline.
