ABSTRACT:
A method and apparatus for monitoring vibrations in a blade structure of a turbine including generating signals from a probe located adjacent to a radial outer edge of the blade structure to provide signals corresponding to vibrations at predetermined locations along the tips of the blades. A leading edge of a blade tip is detected during a blade tracking operation, and a known location along the length of the blade tips is monitored during a vibration measurement operation. The measurement operation may be performed simultaneously with the tracking operation to provide measurements as the axial location of the blades change during transitional modes of operation of the turbine.
