Abstract

L’invention concerne un endoscope (40) de nettoyage d’une aube (24, 34) de turbomachine d’aéronef, cet endoscope (40) comportant une extrémité proximale (46) et une extrémité distale (48) comportant un système d’éclairage et de visualisation depuis ladite extrémité proximale (46). Selon l’invention, l’extrémité distale (48) de l’endoscope (40) comprend en outre une tête (52) d’émission d’un faisceau laser de nettoyage (57), ce faisceau laser (57) étant configuré pour créer un plasma d’ablation de matières corrodées/oxydées (59) de l’aube (24, 34). Figure pour l'abrégé : Figure 5The invention relates to an endoscope (40) for cleaning an aircraft turbine engine blade (24, 34), this endoscope (40) comprising a proximal end (46) and a distal end (48) comprising a illumination and viewing from said proximal end (46). According to the invention, the distal end (48) of the endoscope (40) further comprises a head (52) for emitting a cleaning laser beam (57), this laser beam (57) being configured to creating a corroded/oxidized material ablation plasma (59) of the blade (24, 34).
