New Sensor Technologies in Aircraft Structural Health Monitoring

Aircraft structural health monitoring is a new in-situ, on line structure detection method which was developed on the basis of the traditional NDT method. It can increase the reliability, safety and run-time of aircrafts while reduce the structures operating and maintenance costs. This paper described this new technology and the principles and application of some new sensor technologies of structural health monitoring. Finally the paper gave a perspective view on further research in this field.
