CRAWLING AUTOMATED SCANNER FOR NON-DESTRUCTIVE INSPECTION OF AEROSPACE STRUCTURAL ELEMENTS

摘要

Apparatus for non-destructive inspection of structural elements or workpieces, in particular those having an airfoil configuration, that moves a scanning sensor across the width (span) of a structural element or workpiece for the purpose of detecting structural damage. In one embodiment, the apparatus simultaneously traverses the length (chord) of the structural element or workpiece. In another embodiment, the apparatus includes a guide rail that encompasses the structural element or workpiece and the scanning sensor travels along the guide rail from a first location at an upper rear region, to the front, of the structural element or workpiece, and then around the leading edge toward the lower rear region. The apparatus includes a processor and a display device to display the processed, sensed, information.
