Abstract

Ensemble (10) de turbine de turbomachine (1) d'aéronef, comprenant au moins un rotor (12) aubagé et un stator (13) aubagé comprenant une première plateforme (131) sur laquelle sont fixées des pales et une deuxième plateforme (133) séparée de la première plateforme (131) par un pied (135), de sorte qu'entre les deux plateformes (131, 133) le stator (13) présente deux cavités annulaires (136, 137). Au moins une tôle annulaire (17) monobloc formant un anneau complet est fixée de manière amovible dans l'une des cavités (136, 137) pour assurer une étanchéité dynamique entre le rotor (12) et le stator (13).
