摘要

Ultrasonic inspection of bases on loaded 155-mm M483A1 projectiles can be hampered by adapter signals caused by contact between base, shim, and adapters. The presence of adapter signals tends to mask the detection signal from cracks. This report offers several ways for enhancing ultrasonic detection signals from cracks in bases fastened to loaded projectiles.
