Abstract

Système (100) comportant un indicateur de fluage (110) sur un organe rotatif (104), et un dispositif de mesure (120) conçu pour mesurer un changement de position radiale de l'indicateur de fluage (110). Le système (100) permet de déterminer, par exemple, l'espérance de vie de l'organe rotatif dans une turbine sans démonter l'organe rotatif (104).
