| Abstract: | In recent studies of the problem of linear stability of a plate in a supersonic gas flow a new (“high-frequency”) type of flutter, which cannot be obtained by means of the piston theory usually employed in these problems, was found to exist together with the classical (“low-frequency”) type. In the present study a new method of calculating the pressure acting on a high-frequency vibrating plate is proposed and, using this method, high-frequency flutter is investigated in the nonlinear formulation and the flutter vibration amplitudes are determined. |
