Device for the non-destructive testing of parts in a turbomachine
View Patent ↗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.
1. A device for the non-destructive testing of parts of a motor, comprising a longitudinal rod at the distal end of which an inspection probe is mounted, wherein the rod carries at its distal end a longitudinal finger carrying a flexible blade supporting the inspection probe, said blade being movable 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 at least partly in front of the finger and the finger being mounted pivotally by one of its ends on the distal end of the rod, about an axis perpendicular to the longitudinal axis of the rod.
2. The device according to claim 1 , wherein the blade is elastically deformable in flexion.
3. The device according to claim 1 , wherein the pivoting of the finger is controlled by a rigid or semi-rigid cable extending along the rod and connected at its distal end to the finger.
4. The device according to claim 1 , wherein the inspection probe is fixed at a free end of the blade.
5. The device according to claim 1 , wherein the blade is fixed removably to the finger.
6. The device according to claim 1 , wherein the blade has at rest an elongate shape curved about an axis perpendicular to its elongation axis.
7. The device according to claim 1 , further comprising an optical observation channel extending along the rod and emerging at its distal end in the vicinity of the distal end of the rod.
8. The device according to claim 1 , wherein the rod carries at its distal end a non-slip damping shoe which, when a part is being inspected, is intended to be in abutment on an element of the motor in order to stabilise the device.
9. The device according to claim 1 , wherein the inspection probe is an eddy current sensor.
10. The device according to claim 1 , wherein said device is configured to test parts in a turbomachine.
11. The device according to claim 1 , wherein said blade has a thickness of less than or equal to approximately 1 mm.
12. A device for the non-destructive testing of parts of a motor, comprising a longitudinal rod at the distal end of which an inspection probe is mounted, wherein the rod carries at its distal end a longitudinal finger carrying a flexible blade supporting the inspection probe, said blade being movable 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 at least partly in front of the finger and the finger being mounted pivotally by one of its ends on the distal end of the rod, about an axis perpendicular to the longitudinal axis of the rod, and wherein the blade is fixed by one of its ends to a ring that the finger passes through and that is mounted so as to slide axially on this finger.
13. The device according to claim 12 , wherein the translation movement of the blade on the finger is controlled by a rigid or semi-rigid cable extending along the rod and connected at its distal end to the ring.
