Abstract

L’invention concerne un aubage instrumenté, par exemple une aube de turbine, comprenant une pale instrumentée (312) s’étendant entre une plateforme radialement interne (304) et une plateforme radialement externe (306), ledit aubage instrumenté comprenant une tige (314) s’étendant entre la plateforme interne et la plateforme externe et réalisée dans un matériau présentant une résistance au fluage supérieure à la résistance au fluage du matériau de ladite aube, la tige étant agencée dans le prolongement amont, ou aval, du bord d’attaque (308), respectivement du bord de fuite (310) de ladite pale instrumentée.
