Sensitive Flutter Parameters Analysis with Respect to Flutter-free Design of Compressor Blade

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.
