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.
By placing NSMS sensors around the rotor's circumference, technicians can look at blade flutter.
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.
However, as the compressor is far away from its design point with large flow incidence angles, continued operation in choke can result in blade flutter and high cycle blade metal fatigue failure for some compressor models.
The co-simulation capability is expected to address applications such as fan blade flutter, microfluidics, in-vivo vascular flows, and flow-induced vibrations in structures and equipment, as well as many consumer goods design and packaging applications.
