SUMMARY
Ultrasound is effectively used to detect fractures in airplane structures by leveraging the principles of acoustic impedance. When ultrasound waves travel through solid materials and encounter a fracture, the difference in mechanical properties causes a significant reflection of sound waves. This reflection occurs because solid materials can transmit high-frequency ultrasound, while air cannot, leading to minimal energy transfer into the air gap. The detection process relies on the principle that a cracked structure will absorb or reflect sound differently compared to an intact one.
