The Glider is a manual 2-axis encoding scanner designed primarily for the inspection of composite and aluminum aircraft parts such as fuselages. The instrument has a cost-efficient design, multi-technology capability and lightweight but rugged construction. It is compatible with phased array (PA) or conventional ultrasonic (UT) probes, as well as conventional eddy current (EC) and eddy current array (ECA) probes. Both axes offer a free-running, incremental or lock mode. The standard, pivot-equipped suction cup pods enable contour following on curved surfaces while the optional magnetic mounting pods extend the versatility of this scanner to corrosion-mapping applications involving ferromagnetic materials. With a light, aluminum frame and removable index arm, the instrument can be transported or reassembled for use on multiple parts. It is available in three sizes, providing scan areas of 46 by 46 centimeters, 61 by 61 centimeters, and 91 by 91 centimeters. It will interface with the OmniScan modular flaw detector or any other data acquisition system.
