A flutter emergency stopper was installed on the III cart device of the 2m×2m transonic wind tunnel at the National Aerospace Laboratory in 1993. Wind tunnel testing with the device revealed that while the decline in Mach number obtained when the flutter stopper opens coincided with the design value, pressure fluctuation did occur. To eliminate this pressure fluctuation, improvements were made to the flutter stopper plate and opening angle . Subsequent test results confirmed the effectiveness and safety of the flutter-suppressing device. This report presents the improvements made to the flutter-suppressing device, the tests conducted and test results.
