Abstract
By analyzing, as an example, a thin elastic rectangular plate streamlined by supersonic gas flows, we study the phenomenon of divergence and of panel flutter of the overrunning of the gas flow at is free edge under the assumption of presence of concentrated inertial masses and moments at the free and fixed edges respectively. Its solution shows that the divergence or the localized divergence and the flutter are possible. The corresponding critical velocities of divergence and panel flutter are obtained. It is shown that depending on the relation between parameters of the problem, the critical flutter velocity can be either smaller or larger than the critical velocity of divergence.
