Сверхзвуковой флаттер удлиненной прямоугольной пластинки с одним свободным краем, растянутой по потоку газа

Abstract

In the article, in a linear formulation, the influence of the initial stress state of an elongated rectangular elastic plate with one free edge, stretched along the gas flow, on the stability of the unperturbed motion of the "plate-flow" linear dynamic system is studied under the assumption that there are concentrated inertial masses on its free edge and moments. An analytical solution of the problem of stability of a dynamical system is obtained. The stabilizing effect of tensile forces on the system is shown.
