MULTI-ZONE AUTOMATIC MAGNETOSCOP INSPECTION SYSTEM
Publication/Patent Number: EP3712605A1 Publication Date: 2020-09-23 Application Number: 20161665.3 Filing Date: 2020-03-06 Inventor: Ouyang, Zhong   Debiccari, Andrew   Brindley william j   Liu, Xuan   Assignee: United Technologies Corporation   IPC: G01N27/83 Abstract: A magnetoscop inspection system (100) includes a magnetoscop (102), a computed tomography unit (116), and a corrosion model unit (118). The magnetoscop measures a permeability at a plurality of inspection points of a turbine component (110). The computed tomography unit generates a measured profile (250) of a hollowed portion of the turbine component based at least in part on the permeability at the measured inspection points. The corrosion model unit stores in memory at least one reference computed tomography profile (600) of a known turbine component. The magnetoscop inspection system determines a structural integrity of the turbine component based on a comparison between the measured profile (250) and the reference profile (600) corresponding to the turbine component currently under inspection.
