spectral kurtois sounds like a brilliant idea for CbM in motors. Please let me know if you have any good references.

I was a helicopter pilot in the NAVY. One maintenance item that needed to be done was rotor blade tracking. Can / is this technology used for rotor blade tracking?

Hi L?onard,
Yes, blade tracking is also done with this kind of equipment, but more with optical sensors, that is sometimes added for temporary measurement, sometimes permanent.
