Abstract
L’invention concerne une turbomachine comportant un compresseur comprenant des aubes fixes à calage variable (11) s’étendant chacune radialement entre un moyeu rotatif (6) et un carter fixe (3) entourant ce moyeu rotatif (6), chaque aube à calage variable (11) comprenant une pale (12) ayant une base (14) espacée par un premier jeu radial (J1) d’une paroi fixe (2) du carter (3), et un sommet (17) espacé par un second jeu radial (J2) d’une paroi rotative (4) du moyeu rotatif (6). La paroi fixe du carter (3) ou la paroi rotative (4) du moyeu rotatif (6) comporte au droit de la pale (12) un traitement de forme agencé pour canaliser une fuite d’air passant traversant le jeu correspondant. Figure pour abrégé : Figure 1
