摘要

A method employing measurement of decay in natural frequency has been developed for rapidly determining the quality of die cast, aluminum alloy, axial flow compressor blades. This method provides a nondestructive, positive means for identifying blades having defects that would impair their performance in axial flow compressors, and can also be used for measuring the endurance strength of the blades.nThree machines employing this method have been constructed. One of these is designed for routine inspection of compressor blades and completes an inspection in one and one-half to two and one-half minutes, depending on the blade design. This rate of inspection allows a lower labor cost for quality control than is-usually obtained by other inspection methods. Another machine is a more versatile laboratory instrument for developmental studies of fatigue and other physical properties of compressor blades and similar cantilever specimens. The third machine combines the features of the two earlier models.
