- Аннотация: Single mode panel flutter is one of two panel flutter types that can occur at low supersonic flow speeds. Over the years it is considered by researchers and engineers as weak and being unable to occur on a real structure due to small growth rate, easily suppressible by the structural damping of the panel. Though recent experiments demonstrated that this opinion is wrong, and single mode flutter can actually occur, it is still unknown what damping level the structure should have to avoid flutter. In this paper we study flutter of damped panels at low supersonic speeds. It is shown that for typical structural damping levels single mode flutter is not always avoidable. Moreover, for some conditions damping level necessary to suppress flutter is too high and cannot be achieved by the structure itself.
