Abstract: | In our recent study of strip plate flutter, two flutter types, low-and high-frequency, were revealed. The first arises due to interaction of the oscillation modes and has been investigated in detail in numerous studies using an approximate piston theory. The high-frequency flutter, detected for the first time, is a consequence of the presence of negative aerodynamic damping and cannot be obtained using the piston theory. In the present study, the high-frequency flutter of a rectangular plate is investigated. |
