Title (EN) TURBINE AND COMPRESSOR BLADE DEFORMATION AND AXIAL SHIFT MONITORING BY PATTERN DEPLOYMENT AND TRACKING IN BLADE POCKETS
(FR) DÉFORMATION D'AUBE DE TURBINE ET DE COMPRESSEUR ET SURVEILLANCE DE DÉCALAGE AXIAL PAR DÉPLOIEMENT ET SUIVI DE MOTIF DANS DES POCHES D'AUBE
Abstract:
(EN) A method of monitoring a rotor blade (14) is provided. The method includes disposing a probe (22) including an optical sensor (25) within a mounting hole in a turbine casing (36) of a turbine engine. A (5) laser beam is them emitted by a light source (54) radially inward from the probe position onto a rotor blade tip (100) of the rotor blade (14). The rotor blade (14) is positioned such that it periodically passes the laser beam. The rotor blade tip (100) includes a predetermined pattern (120). The reflected light images from the rotor blade tip (100) are received by the optical sensor (25). From the (10) reflected light images, a blade profile is constructed. Based on this constructed blade profile from the reflected light images off the predetermined pattern (120), a position of the rotor blade (14) is determined. A system of monitoring a rotor blade (14) is also provided.
(FR) L'invention concerne un procédé de surveillance d'une aube (14) de rotor. Le procédé comprend la disposition d'une sonde (22) comprenant un capteur optique (25) à l'intérieur d'un trou de montage dans un carter (36) de turbine d'un moteur à turbine. Un faisceau laser (5) est émis par une source de lumière (54) radialement vers l'intérieur depuis la position de sonde sur une pointe (100) de l'aube (14) de rotor. L'aube (14) de rotor est positionnée de telle sorte qu'elle passe périodiquement devant le faisceau laser. La pointe (100) d'aube de rotor comprend un motif prédéfini (120). Les images de lumière réfléchie provenant de la pointe (100) d'aube de rotor sont reçues par le capteur optique (25). À partir des images (10) de lumière réfléchie, un profil d'aube est construit. Sur la base de ce profil d'aube construit à partir des images de lumière réfléchie du motif prédéfini (120), une position de l'aube (14) de rotor est déterminée. L'invention concerne également un système de surveillance d'une aube (14) de rotor.
