Large Area Instant Crack Detection and Identification Using Magnetic Carpet Probe

Abstract

Over the years, engine reliability has improved steadily as technology advances. Working in partnership, government and industry have agreed to use enhanced inspections for certain high-energy rotating engine components. Magnetic Carpet Probe (MCP) is one among these efforts. MCP is a two-dimensional coil array built on a piece of very thin, smaller or equal to 0.015" (0.38 mm), flexible printed circuit board called Flex Circuit. Placing an MCP on top of a metallic surface under inspection one can finish the inspection, without moving anything, and see the crack identification image on the instrument screen in a few second. Actually a two-dimensional scan is going on electromagnetically within the MCP.
