Abstract
It is possible to measure rotating blade vibrations in a turbomachine by stationary sensors mounted on the casing. Optical sensors appear best suited for these measurements. A prototype fiber-optic sensor is proposed, its scheme is described and its performance presented. The design choices are discussed with respect to the desired performance; general conclusions about the use of optical sensors for such measurements are drawn.File in questo prodotto:
