  • Probe for inspecting the surface of a circumferential slot in a turbojet disk by means of eddy currents
    Patent number: 8866471
    Abstract: A probe for eddy current monitoring of the surface of a circumferential slot formed in a turbojet disk. The probe includes a stem fastened to a support and a first multi-element sensor constrained to move with the stem and configured to be inserted into the circumferential slot to perform the inspection, and a second multi-element sensor. The two multi-element sensors are disposed back to back, and the stem of the probe is mounted to pivot about its own axis to enable the two multi-element sensors to be inserted in the slot.
    Type: Grant

  • Method and an installation for using eddy currents for non-destructive inspection with automatic calibration
    Patent number: 7800363
    Abstract: Using eddy currents for automatic inspection of a rectilinear hole formed in a metal part. An eddy-current probe is carried by a drive system associated with a positioning baseplate that carries a calibration part including a hole similar to the hole for inspection and in alignment with an orifice thereof.
