ОБ УСТОЙЧИВОСТИ ШИРОКОЙ ПАНЕЛИ СО СВОБОДНЫМ КРАЕМ, РАСТЯНУТОЙ ПО СВЕРХЗВУКОВОМУ ПОТОКУ ГАЗА, ПРИ НАЛИЧИИ СОСРЕДОТОЧЕННЫХ ИНЕРЦИОННЫХ МАСС И МОМЕНТОВ

- Abstract
The paper investigates the influence of the initial stress state of a sufficiently wide rectangular elastic plate on the stability of the linear dynamic system "plate-flow" under the assumption that there are concentrated inertial masses and moments on the free edge of the plate stretched along the gas flow. An analytical solution of the systemяхstability problem is found. The possibility of loss of stability of the system only in the form of a localized divergence is shown. It has been established that the initial longitudinal tensile forces lead to a significant increase in the stability of the system.
