Abstract

Du gaz de ventilation est soufflé vers un anneau de stator (3) pour régler sa distance du bout d'aubes mobiles (5) et diminuer les fuites dans une turbine de machine. On propose d'opérer des communications entre chambres successives (18, 19, 20) à travers des crochets (26, 27, 28 et 29) de fixation d'une entretoise (10) de support de l'anneau (3) au carter (2), afin de réduire les concentrations de contrainte dans cette entretoise (10).
