  • 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.
