    Abstract: A blade handling system and method for conducting tomography (x-ray) scans of wind turbine blades to detect various types of manufacturing defects before blade installation are provided. The blade handling system includes support trollies, at least one of which is partially formed from low density materials that do not absorb X-rays, at least in the portions that directly contact the blade or are adjacent to the blade. The blade handling system engages the blade with a rigid support arrangement that immobilizes the blade against vibrations such that the blade can be moved past a tomography scanner and an accurate X-ray scan can be taken of the blade, unaffected by the support trollies. Longitudinal scans and detailed re-scans of certain cross sections using CT scanning by the tomography scanner are used to detect and diagnose many different types of manufacturing defects.
