dcterms:description
A novel method of contactless measurement of turbine blade vibration during increasing (decreasing) operational speed is presented. The method is based on evaluation of time differences of blade passages along contactless sensors placed on the stator, and substitutional data correction using a numerical model. The method has been verified both numerically and experimentally. For the experimental research on the bladed model wheel of the Institute of Thermomechanics and subsequent applications under operating conditions, two new types of sensors functioning on magnetoresistive and induction principle have been developed.
