摘要

The invention relates to a turbine distributor for a turbine engine that comprises inner (32) and outer annular platforms connected by blades (36), the inner platform (32) bearing annular members (44) made of an abradable material and interacting with the annular lips of a rotor of the turbine engine in order to form a labyrinth-type seal, wherein the members made of an abradable material are carried by annular sheet segments (52, 52', 66) having a substantially L-, S- or C-shaped section and attached by brazing or welding at their outer periphery to the inner platform, and at their inner periphery to the members made of an abradable material.
