FIBER OPTIC SENSING DEVICE AND METHOD FOR MONITORING FOIL BEARINGS

摘要

A rotary machine includes a rotary component disposed to rotate with respect to a stationary component. A foil bearing is disposed between the stationary component and the rotary component and configured to rotatably support the rotary component. A fiber optic sensing system including one or more fiber optic sensors is disposed in the foil bearing and configured to detect one or more parameters related to the foil bearing.
