Abstract
A new invented SHM technology, named as Intelligent Coating Monitoring (ICM), was verified by various lab-scale experiments as along with full-scale fatigue tests to inspect ICM capability for monitoring crack initiation and propagation in metal substance. In order to apply the technology to fighter aircrafts, ICM system was validated at real service condition. Firstly, ICM is briefly introduced, including the principle of sensor, the make-up of the system and various lab-scale experiments as well as full-scale fatigue tests for verification and application. Then the installation of ICM system on an operational aircraft structure was given which includes the determination of critical locations that needs monitoring, the selection of sensors corresponding to each monitoring point with certain geometry, the method of sensors splicing and main-/subinterrogation units fixing and the connection of the above hardware through wires laying to form a ICM system. Finally, the operating situation and the effectiveness of the ICM system under operational environment were validated and summarized.
