Abstract

L'invention concerne une turbine comprenant une roue aubagée tournant autour d'un axe longitudinal (AX), et un carter (16) formant stator entourant cette roue aubagée et portant des éléments abradables (18, 19), la roue aubagée comportant des aubes dont les extrémités sont terminées par des léchettes (21, 22) situées en vis-à-vis des éléments abradables (18, 19). Chaque élément abradable (18, 19) est porté par un système réglable permettant d'ajuster sa distance par rapport à l'axe longitudinal (AX).
