The techniques may enable detecting cracks present in engine parts while the engine is operational. In one embodiment, a system (10) includes a wireless sensor (32) configured to be disposed on a movable part (14,24,26,28) internal to a machine and communicate (12) wirelessly and a controller (34) that includes a processor (35).

摘要： Tube inspections are performed by combining the use of APR technology with GW technology. The reflections measured by both technologies are compared to each other and used to more specifically identify the type and location of a flaw or anomaly that appears in the interior of the tube. Further, embodiments of novel probes to be used in GW technique for inspecting tubes with mechanical waves having bandwidth that is equal to 150 KHz or more are disclosed.

摘要： A high frequency method for determining the non-propagation threshold of fatigue cracks in which a cyclic load (32, 32A) is applied to at least one test piece comprising, in a test area (10A), an elliptical hole (12) having a notch (14) at one apex, and held between two rigid masses (24, 26), two rigid prestressing plates (20, 22) being disposed on either side of said test piece and being secured at each of the two ends (20A, 22A; 20B, 22B) of same to the two rigid masses, the frequency of the cyclic load (32, 32A) being chosen as equal to the natural frequency of the test piece/masses/prestressing plates assembly so as to generate a fatigue crack from the notch; then, when it is observed that the crack has stopped propagating, the final length of the crack is recorded, and said non-propagation threshold ΔK
th of the fatigue crack is determined using a table, the cyclic load being obtained by a vibrating electrodynamic pot integrally attached by means of rigid posts to a frame supporting the two rigid masses and comprising a push rod to transmit said cyclic load to the test piece/masses/prestressing plates assembly.
