Abstract
We describe the recent development of Sonic IR Imaging (SIR) NDE for aircraft structures. In the Sonic IR imaging NDE technique, a short ultrasonic pulse is applied to the aircraft/aircraft structures to excite the defects to heat up, while an infrared camera images the time evolution of the heating effect to identify the defective areas in the target. In this paper, we’ll show our study with sonic IR imaging on aircraft structures and components from B747, B737, and B727.
