摘要： An eddy current device for inspecting a component, such as a closed surface area of a gas turbine engine or the like, includes an eddy current array circuit having an active face for positioning on a surface portion of the component during an inspection operation and backing on a surface of the eddy current array circuit opposite to the active face. The eddy current array circuit and backing are disposed over the operating face and expandable sides of an extendible pin. The extendible pin has a slot formed therein with interior side edges which narrow toward the operating face of the pin at a predetermined slope. The expanding pin is positioned to cause the angled sides to mate while engaging the interior angled sides of the round or shaped hole to cause the exterior sides of the expandable pin to expand outwardly a greater distance as the pin is pushed deeper into the hole. This causes the eddy current circuit to conform with the shape of the surface to be inspected. The array sensor is so shaped that it can cover the closed surface in as little as one scan.

摘要： An intermediary device is provided between an eddy current bolt hole inspection machine and an associated eddy current probe to positionally align the probe in each bolt hole to be inspected. A first end of the device is attachable to the eddy current bolt hole inspection machine, and a second end, having a tightening bolt, is attachable to the eddy current probe. A collet associated with the second end of the device secures the probe to the device when the tightening bolt is tightened subsequent to the second end accepting the eddy current probe. An adjustable flange component has a first portion separated from a second portion via a spring wave washer to allow the second portion to move left to right and front to back, relative to the first portion.
