Abstract

L'invention concerne un moyeu (24) d'hélice (12, 14) propulsive ou de soufflante non carénée de turbomachine, comportant une paroi (26) sensiblement annulaire d'axe A et comprenant des moyens (28) de montage de pales (20, 22) de ladite hélice (12, 14) répartis angulairement de manière régulière autour dudit axe A, caractérisé en ce qu'il comporte : - au moins une paire de transducteurs piézo-électriques (36, 37), émetteur (37) et récepteur (36), s'étendant sur au moins une partie de la paroi (26) du moyeu (24), chaque récepteur (36) fournissant une réponse de la paroi à une sollicitation de l'émetteur (37), dans une zone (Z) de proximité dudit récepteur (36), - des moyens d'interrogation (40) du récepteur (36) configurés pour délivrer ladite réponse, - des moyens de traitement (42), configurés pour comparer chaque réponse de la paroi (26) fournie par récepteur (36) à une réponse de référence de la paroi dans la zone (Z) de proximité dudit récepteur (36) et pour émettre, en cas de différence entre ces réponses une information (I) représentative d'une crique ou d'une fissure (38), - des moyens d'émission sans fil (46), reliés auxdits moyens de traitement (42), qui sont configurés pour émettre un signal contenant ladite information (I).The invention relates to a hub (24) for a propeller (12, 14) propeller or non-faired fan of a turbomachine, comprising a substantially annular wall (26) of axis A and comprising means (28) for mounting blades ( 20, 22) of said propeller (12, 14) distributed angularly in a regular manner around said axis A, characterized in that it comprises: - at least one pair of piezoelectric transducers (36, 37), transmitter (37) and receiver (36), extending over at least a portion of the wall (26) of the hub (24), each receiver (36) providing a response from the wall to a bias of the transmitter (37), in a zone (Z) of proximity to said receiver (36), - interrogation means (40) of the receiver (36) configured to deliver said response, - processing means (42), configured to compare each response of the wall ( 26) supplied by receiver (36) to a reference response of the wall in the zone (Z) of proximity to said receiver (36) and to transmit, in the event of a different between these responses there is information (I) representative of a crack or a crack (38), - wireless transmission means (46), connected to said processing means (42), which are configured to transmit a signal containing said information (I).
