Note (General): A new noncontact measuring system for rotating blades vibrations of fans, compressors, and turbines has been developed and successfully applied in the research and development project of turbofan engines and industrial gas turbines. It is a powerful measurement system which can simultaneously measure the vibration of all blades without the need of such processing of blades and rotor as in traditional strain gage measurement. The system consists of optical fiber blade-tip detecters on the peripheral of the engine casing, signal processing/data acquisition subsystem and control/calculation/display subsystem. Software is devised to insure valid data and high handling qualities of the system. Results of measurement are displayed on a sub-realtime basis in the on-line monitoring mode as vibration wave forms of a few blades and bar-graphs for the maximum vibration amplitudes of all the blades. Also an off-line data processing mode is available for later analysis and review. The present paper describes the measuring principle, the system performance and the hard- and software, and in addition, some results of application and calibration which show good agreement with those of strain gage measurement.
