Endoscopic Fluorescent Penetrant Inspection (FPI)

摘要

Traditional endoscopic inspections sometimes do not allow to determine the nature and threat of an indication. There are suspicious indications like black marks, scratches, blade impact or residual crack after blending operation. To resolve the doubt, Snecma, in association with EFER Endoscopy company, developed various technologies allowing to apply a FPI operation inside the reactor to bring out discontinuties in the blades surface.
