A very hazardous\u003c\/p\u003e\u003cp\u003ephenomenon is fl utter, a self-excited form of vibration,\u003c\/p\u003e\u003cp\u003ewhich is caused by fl uid energy transferred into the blade\u003c\/p\u003e\u003cp\u003estructure. To mitigate fl utter the designer can chose between\u003c\/p\u003e\u003cp\u003eaerodynamic and mechanical measures. The present work\u003c\/p\u003e\u003cp\u003efocus on the impact of the blade shape to modify the exciting\u003c\/p\u003e\u003cp\u003eunsteady pressure fi elds leading to fl utter. Analytical as well\u003c\/p\u003e\u003cp\u003eas numerical approaches are presented, which examine the\u003c\/p\u003e\u003cp\u003elink between steady aerodynamics and the vibration induced\u003c\/p\u003e\u003cp\u003eunsteady pressure.
