Recent Developments of Aircraft Nondestructive Evaluation Based on Advanced Sensor Techniques
The safety and structural integrity are of great importance to military and commercial aircraft, and the developments of effective nondestructive evaluation (NDE) methods are receiving much attention in recent years. The objective of this paper was to provide the recent developments of aircraft NDE based on advanced sensor techniques: (a) Ultrasonic testing with piezoceramic sensor arrays, air-coupled transducers, and dry-coupled transducers; (b) Eddy current testing with SQUID magnetometer sensors, Hall effect sensors, and giant magnetoresistive sensors; (c) Optical testing techniques including thermography with infrared sensors, laser shearography with CCD sensors; (d) Other NDE methods including microwave testing with waveguide sensors, vibration monitoring with fiber optic sensors, and magnetic resonance testing with NMR sensors. The characteristics of these sensor techniques and the corresponding NDE methods were reviewed combining various practical applications in aircraft materials and structures. The developing trend of the advanced sensors based aircraft NDE methods was directed.
