Keywords: health monitoring, aircraft fuselage, ultrasound

A numerical investigation was conducted into the use of propagating stress waves for the detection of defects in a typical aircraft fuselage structure, comprising a skin, stringer and frame. The feasibility of defect detection was analysed and the limitations in detection due to the complex airframe structure were highlighted.
