As the mission requirements of the aero engine improve, the blade aerodynamic loading is higher, especially for lightweight designed blade. The possibility of the blade self-excited vibration increases, so flutter becomes one of the problems for fan and compressor design. However, there is no flutter related parametersin engineering as a reference for compressor flutter-free design until now. That is why the sensitive flutter parameters were studied which could suppress the flutter.
