Background,Motivation and Objective Ultrasound technologies are of great interest for aeronautical structure inspection.Mainly deployed through Phased Array(PA) ultrasonic transducer,ultrasound inspection is thought as a local examination of the structure to determine geometry,damage or composition of invisible flaws like cracks,delamination and corrosion.This approach in aeronautical structure cannot be easily automated since it requires access to area of interest with various complex geometries,along a spatial inspection sampling in agreement with the structure composition and vulnerability requiring a high degree of human interaction.
