Abstract
Est concernée une turbine comprenant un dispositif d'étanchéité entre un stator et un rotor (11) apte à tourner par rapport au stator autour d'un axe (X) de la turbine. Le dispositif d'étanchéité comprend : - au moins un élément en matériau abradable disposé fixement par rapport au stator, - au moins une léchette (36) dont est pourvue une portion du rotor (11) et qui est adaptée à coopérer avec ledit élément en matériau abradable, pour l'étanchéité. La léchette (36) présente en extrémité libre, sur au moins un tronçon (363) de circonférence, un profil irrégulier, avec radialement au moins une excroissance (367).
