2.2 - Robust and Miniaturized Non-Incremental Fiber-Optic Distance Sensor for Turbo Machine Rotor Deformation and Vibration Monitoring

P. Dreier, T. Pfister & J. Czarske
In order to improve the safety, the lifetime, and the energy efficiency of turbo machines, the dynamic behaviour of the rotor has to be analyzed and optimized. Thus, rotor unbalances, dynamic deformations, and blade vibrations as well as blade tip clearance changes have to be monitored during operation for optimizing the rotor design and to validate numerical models. However, these are big challenges for metrology, since small, robust, and noncontact measurement techniques are required offering...
