Abstract
A probe is pulled along a cooling slot of a turbine wheel to detect defects along the slot surfaces. The cooling slot extends radially inwardly of the bases of both the dovetails and dovetail slots. A housing assembly is releasably coupled to the rim of the turbine wheel and a motor draws the probe along the cooling slot at constant speed. A guide and brushes on the probe serve to bias the probe radially outwardly against the surfaces to be inspected as the probe is drawn along the cooling slot.
