Abstract: The method includes positioning a probe of the phased array ultrasound system on the mounting portion of the anisotropic rotor blade at the axial centerline. The method further includes scanning a sector of the anisotropic rotor blade along the axial centerline with the probe of the phased array ultrasound system. The method further includes determining a magnitude and a time delay of an echo signal corresponding with a geometric fiducial marker. The method further includes adjusting a position of one of the anisotropic rotor blade or the probe based on the magnitude and/or the time delay of the echo signal corresponding with the geometric fiducial marker. The method further includes repeating the scanning, determining, and adjusting steps until the magnitude and the time delay of the echo signal corresponding with the geometric fiducial marker is within a predetermined maximum echo range. The method further includes scanning the anisotropic rotor blade for defects.
