Belubekyan, S. Martirosyan] By analyzing, as an example, a thin elastic elongated plate hinged along its long edges and streamlined by supersonic gas flows, we study the effect of destabilization for different models of structural friction in the hinges under the assumption of presence of concentrated inertial moments on the fixed edges. We establish the relationship between the characteristics of natural vibrations of the hinged plate and the velocity of the streamlining gas flow, which enables one to draw some conclusions concerning the stability of disturbed motions of the plate depending on the chosen model of structural friction. For different models of structural friction in the supports, we determine the critical velocity of the gas flow leading to the flutter instability.
