Aeroelastic Investigations of Turbomachinery Blades.

Kurzfassung

Due to higher aerodynamic blade loading, the investigation of aeroelastic phenomena such as flutter or forced responses becomes increasingly important. For this reason, great efforts have been made in the past to develop theoretical and experimental methods to predict stability boundaries and dynamic response of the blades with an acceptable level of accuracy. The Institute of Aeroelasticity concentrates its activities in the field of turbomachine aeroelasticity on two items: the development of CFD codes to compute unsteady lift and moment coefficients for vibrating blades and the experimental investigation of blade flutter.
