SIMPLIFIED IMPEDANCE PLANE BONDTESTING INSPECTION BY ULTRASONIC MEANS |
摘要 |
An NDI system includes an ultrasonic transducer and an electronic device having an indicator, such as a light source. The electronic device energizes the transducer, receives sinusoidal signals from the transducer, determines impedance-plane coordinates corresponding to quadrature-phase separated com ponents of the sinusoidal signals, and automatically activates the indicator if impedance-plane coordinates exceed a preset threshold. The system may be used in methods of inspecting layered structures such as composite aircraft components and repair patches applied to such structures.
