This paper presents the results of combined experimental and theoretical studies performed to develop an efficient inspection procedure to detect small cracks of radial orientation in turbine engine disk components. After selecting an optimal transmit-receive probe for proper coverage of the inspection area, further work has dealt with the maximization of the small-defect response in view of the inspection parameters. Experimental and simulation results are presented
