Abstract | A method for monitoring the health of a plurality of blades 12 is presented. The method includes the steps of determining 106 delta TOAs corresponding to the plurality of blades 12, determining 404 a standard deviation utilizing the delta TOAs corresponding to the plurality of blades; determining 412 a delta sigma_1 utilizing the standard deviation and an initial standard deviation, determining 414 a normalized delta TOA corresponding to one or more of the plurality of blades utilizing the delta sigma_1, determining 416 a standard deviation of the normalized delta TOA, determining 418 a delta sigma_2 utilizing the standard deviation of the normalized delta TOA and a previous standard deviation of normalized delta TOA, and determining 418 a corrected delta TOA corresponding to the one or more of the plurality of blades based upon the delta sigma_2. |
