<p>A method is provided for analysing blade displacements detected by a plurality of circumferentially spaced stationary timing probes associated with an assembly of rotating blades mounted on a rotor. The blade displacements correspond to the times at which the blades pass the respective probes. The method includes the step of:
determining, for successive rotations of the assembly, one or more correlation factors for respectively one or more of the blades, each correlation factor quantifying the degree of correlation between the zeroed blade displacements for a particular blade on a particular rotation and modelled blade displacements corresponding to possible blade vibrational deflections on that rotation.</p> |
