    Abstract
  • To monitor the fatigue crack of aircraft metallic structure in real-time, a scheme for fatigue crack monitoring of aircraft metallic structure based on flexible planar eddy current array sensor is put forward. The characteristics of sensor were analyzed via semi-analytic model, and feasibility of scheme was verified through monitoring experiment based on constructed fatigue crack monitoring system. The result of semi-analytic model shows that the curves of phase difference and amplitude ratio between sensing channel and driving channel varying by lift-off and the conductivity of material under test have singularity and the amplitude ratio changes greatly. The result of fatigue crack monitoring experiment of 2A12-T4 aluminum alloy under constant load indicates that the first channel of sensor is capable of monitoring on accumulated damage and the other three channels are capable of quantitative monitoring on fatigue crack, with monitoring precision of 1mm. The proposed flexible planar eddy current array sensor achieves the whole lift cycle monitoring of specimen from accumulated damage to fatigue crack propagation.
