Abstract
A system and method for radiographic inspection of airfoil structure on aircraft includes a radiation source located on one side of the airfoil structure and an X-Y scanning device located on an opposing side of the airfoil structure. The X-Y scanning device is positioned to receive radiation from the radiation source. A radiation detector is mounted on the X-Y scanning device so as to be moveable relative to the airfoil structure along t two mutually orthogonal axes. In operation, the radiation detector is moved in a predetermined raster pattern while the radiation source is emitting radiation. This allows a large area to be inspected with single positioning of the X-Y scanning device, thereby improving throughput. The radiation detector converts impinging radiation into electrical signals, and a computer system processes the signals to generate radiographic images of the airfoil structure.
