Shrouded turbine blade vibration monitor

Patent ·
OSTI ID:6969595
This patent describes a system for monitoring the vibration of a plurality of turbine blades configured in a row. It comprises: a sensor for sensing a profile of the turbine blade row under dynamic conditions; means for storing an expected profile of the turbine blade row; means for comparing the sensed profile to the expected profile to detect displacement of the turbine blades due to vibration; means for determining the existence of vibration from the detected displacements; and output means responsive to the means for determining.
