blade flutter

blade flutter

The oscillations of a propeller blade on its axis by the fracture of the structure. The number of power strokes in a given RPM provides impulses for the oscillation.

Some examples of local oscillations on the other hand are represented by the blade flutter and the blade excitation due to rotor-stator interaction or to vortex shedding or cavitation oscillations.
The company applies multiphysics technologies from ANSYS in designing high-pressure turbine blades, for blade flutter analysis, and for engine noise performance simulation.
Target applications for FSI include, flow-induced vibrations in structures and equipment, fan blade flutter, in-vivo vascular flows, microfluidics, and consumer products design and packaging applications.
The system identifies blades with propagating cracks; locates small geometry changes; and detects blade flutter, potentially damaging aerodynamic events and rotor torsional events.
