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.

The result from 1800 rpm which is below the blade flutter instability speed shows that the cutting deviation is small, compared with the results from conducting cuts at 2800 rpm which is above the instability speed of the blades.

What this means: Fluid-structure interaction (FSI) problems are complex physics problems that run rampant throughout automotive design (e.g., flow-induced vibrations in moving vehicles, fan blade flutter, passenger compartment ventilation, and heat transfer conditions).
By placing NSMS sensors around the rotor's circumference, technicians can look at blade flutter. Since the NSMS sees all of the blades in a stage as they pass by individually, the system gathers data for modal analyses.
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.
