The new Non Destructive Inspection (NDI) technology for aircraft has been required to reduce maintenance cost and to increase efficiency for aircraft operation. This document shows the experimental result obtained by ultrasonic Non Destructive test using Lamb wave which is one of the promising new NDI technologies. In this experiment, we used Acoustic Emission (AE) Sensor as the vibration source to propagate Lamb wave into the flat Aluminum panels. We investigate the propagation characteristic of Lamb wave and examine the capability of this method about the damage detection and identification for damages as NDI technology. The Multi-axis Vibration Evaluating System (MaVES) which JAXA developed is used to detect the Lamb waves in Aluminum panels.
