Detecting mixed-mode oscillations due to compressor blade flutter
The paper presents a study of time-evolving compressor blade flutter. The compressor rotation frequency is a natural control parameter of the blade flutter. It has been found that, as the compressor rotation frequency increases, a blade mode instability sequence predicted by the theory of compressor blade flutter can be changed. After a blade torsion flutter, a more complex bending-torsion flutter evolves due to a temporal internal resonance between the blade torsion and acoustic diametral mode. So a blade collective mixed-mode oscillation is detected in the compressor under study. Next, with an increase of rotation frequency, the internal resonance is leaved, and the blade flutter becomes pure bending and non-linear.
