Acoustic Emission Detection of Crack Presence and Crack Advance During Flight


Results are presented which show that it is possible to detect crack growth and crack presence in airframe components during flight. To accomplish this, a data acquisition system has been developed specifically for in-flight applications. It is shown that crack advance of less than 1 mm2 was readily detected during flight and the fracture-related acoustic emission signals unambiguously identified.
