RUNNING FLUTTER WAVES IN BLADES CASCADE
Půst L., Pešek L.
pages 814 - 817, full text

The simplified mathematical model of dynamic properties of bladed cascade excited by wakes of flowing steam from the stationary cascade is derived. Interaction of this kind of forced excitation with aeroelastic self-excitation described by Van der Pol formula causes origin of flutter and its. running waves. It is shown that the velocity, direction of flutter running waves and mode of vibration depend on the blades’ number ratio and on kind of self-excitation forces on individual blade or on inter-blade distance.
