Design of High-Frequency, Focused Transducers for the Inspection of Turbine Blade Attachments

摘要

The technique developed for attenuation measurement has successfully obtained the attenuation for frequency range used in the calibration block. These results show the reason for loss of high frequency components in the waveforms. Also, the results show-that by modifying the material used in the calibration test, one could obtain a better signal with higher frequency.
