Abstract

The stator shroud is made up of components (2) juxtaposed so as to form circumferences, which are successive and assembled separately to a common housing which surrounds them. Characteristically, the assembly is made with only one single fixing point (7) per component (2), while being completed by a support point (21) sliding along the circumference. The result is a more flexible component assembly and a more even distortion, which allows better control of the clearances between the shroud and the rotor blades it surrounds.
