Vane vibration measuring method for turbine blade, involves transmitting discrete Fourier transform result to analysis device in form of frequency spectrum to find vibration frequencies of associated vane

The method involves producing a measurement of displacement of apex of at least one vane of a turbine blade (7) with respect to a rest position, if the vane did not vibrate, by an instrumentation device (10) to generate a discrete Fourier transform, for a set of frequency values. The device transmit...
