Crack detectors for aerospace applications encompass sensors and instrumentation used to identify fatigue cracks, fractures, and structural discontinuities in airframe and engine components, employing technologies such as eddy current (EC) probes, acoustic emission (AE) transducers, and piezoelectric elements operating on ultrasonic pulse-echo or pitch-catch principles, often integrated with structural health monitoring (SHM) systems.
