  • 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

  • Patent number: 7800364
    Abstract: An inspection device for inspecting tangential recesses in a rotor disk by means of eddy currents is disclosed. The device includes a probe containing a plurality of sensors arranged to acquire a plurality of data series during a scan stroke, and the probe is mounted on moving equipment that is slidable in a support that is provided with two positioning members for co-operating with recesses neighboring the recess for inspection.

  • Patent number: 7768259
    Abstract: Using eddy currents to inspect a hole that is possibly not rectilinear and/or of section that is not circular. The inspection device comprises a stick shaped and dimensioned to be capable of being engaged in said hole, at least one arm hinged to a support fastened to one end of the stick, an eddy current sensor being embedded in said arm, and resilient means for urging the arm outwards against the inside surface of the hole.

  • Patent number: 7659715
    Abstract: Inspecting an open cavity by successive broaching movements of an eddy-current sensor. The inspection device includes a probe body including the sensor installed laterally in the vicinity of the end of a rod and in line with a ramp, together with a resilient bias device acting on the probe body.

  • Patent number: 7305898
    Abstract: An installation for non-destructive inspection makes use simultaneously of sensors responsive to different physical characteristics. In an example, a sensor support, e.g. a kind of carriage having running wheels via which it comes into contact with the surface to be inspected, is fitted with two types of sensor, namely an eddy current sensor and at least one ultrasound sensor.
