Abstract

Dispositif de détection d'un défaut sur une surface (18b) d'un matériau abradable (18) d'un carter de turbomachine (10), le dispositif (4) étant destiné à se positionner sur un carter de turbomachine (10), d'axe longitudinal (A), muni d'un matériau abradable (18) présentant une surface principale (18b) annulaire longitudinale délimitée à chacune de ses extrémités longitudinales par un flanc radial (18a), caractérisé en ce que le dispositif (4) comprend un comparateur (9) permettant de détecter une variation de l'épaisseur du matériau abradable (18) lors d'un déplacement du dispositif (4), le dispositif de détection (4) étant configuré pour se déplacer, selon une même direction circonférentielle (B), sur l'un des flancs radiaux (18a) et sur la surface principale (18b) du matériau abradable (18).Device for detecting a defect on a surface (18b) of an abradable material (18) of a turbomachine casing (10), the device (4) being intended to be positioned on a turbomachine casing (10), with a longitudinal axis (A), provided with an abradable material (18) having a longitudinal annular main surface (18b) delimited at each of its longitudinal ends by a radial flank (18a), characterized in that the device (4) comprises a comparator (9) making it possible to detect a variation in the thickness of the abradable material (18) during a movement of the device (4), the detection device (4) being configured to move, in the same circumferential direction (B), on one of the radial flanks (18a) and on the main surface (18b) of the abradable material (18).
