| Abstract: | A rather sophisticated guided wave technology is introduced to solve a practical aging aircraft problem of delaminations and/or corrosion detection in either a lap splice joint or a tear strap. A Double Spring Hopping Probe is designed to achieve excellent contact on a curved aircraft structures. A guided wave resonance tuning concept for frequency is also discussed with respect to attaining reliable bond integrity measurements. A variety of experiments are discussed including experiments performed during the field trial on a Boeing 737-222 aircraft. |
