Abstract (en)
[origin: WO2021191540A1] A distributor made up of sectors (15) of stator vanes (5) connected, on the outside, to a stator comprises an inner platform divided into an outer portion formed of sectors and joined by radial slide connections to a continuous inner ring-shaped portion (18) over a circumference, which bears an abradable seal (17). Springs (27) ensure the radial positioning of the crown (18) and its concentricity to the rest of the machine. The diameter of the crown (18) is essentially determined by the temperature of the gases that move past it. The separation of the radial thermal deformations is ensured by slides (35) made up of sliding sleeves (19, 20). It is possible for better sealing to be obtained.
