, 1986 An automated, computer controlled inspection system is being developed under the Retirement for Cause (RFC) Program. This inspection system is responsible for the reliable detection of flaws of critical sizes in an assortment of locations and orientations on multiple disks and spacers in the fan, compressor and turbine sections of the F100 aircraft ...

Eddy Current Probe Performance Variability
, 1987 Eddy current testing is used extensively by the Air Force for nondestructive inspection of many aircraft structural components. Although the reliability and consistency of inspections depends to a large extent on the characteristics of the eddy current probes used, no adequate specifications or certification methods presently exist for assuring probe ...

Effects of residual magnetism due to minor loop on magnetic property of permanent magnet type of MRI [PDF]
, 2002 Summary form only given. The flux distribution of a permanent magnet type of MRI shown in Fig.1 is affected by the hysteresis (minor loop) and eddy currents in the pole piece and yoke due to the pulse current (Fig.2) of the gradient coil.
