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.

Probe for inspecting the surface of a circumferential slot in a turbojet disk by means of eddy currents

A flexible and steerable structure for non-destructive inspection, the structure including a longitudinal body and at least one actuator enabling the curvature of at least a portion of the longitudinal body to be modified, the actuator being carried by a support associated with the longitudinal body and including a distal portion that is spaced apart or that is spaceable apart from the longitudinal body and that is connected to a portion of the longitudinal body by a traction line.

Endoscope-like adjustable structure

A device for non-destructive in situ inspection of parts of a turbine engine, the device including a stick carrying at its distal end a pivoting finger carrying at one of its ends a blade for supporting an inspection probe, and at its opposite end a skid for bearing against and/or catching on an element of the engine, the skid being movable in a direction parallel to the longitudinal axis of the finger.

Device for checking a turbomachine engine

A device for the non-destructive testing of parts of a turbomachine motor, including a longitudinal rod carrying at its distal end a longitudinal finger carrying a retractile or deployable flexible blade supporting an inspection probe, this blade being guided in axial translation on the finger between a retracted position in which it extends along the finger and an advanced or deployed position in which it extends in front of the finger.

Device for the non-destructive testing of parts in a turbomachine

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.

Device for non-destructive eddy current inspection of a hole formed in a conductive part

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.
