TURBOMACHINE TURBINE HAVING CMC NOZZLE WITH LOAD SPREADING

The invention relates to a turbine (1) having a casing and a nozzle (2), comprising an outer metal shroud (9) rigidly connected to the casing, an inner metal shroud (5), and a plurality of CMC nozzle sectors (20) forming a ring extending between the outer metal shroud (9) and the inner metal shroud (5), each sector (20) comprising a mast (6), an inner platform (24), an outer platform (26) and at least one blade (28) having a hollow profile defining an inner recess, the inner and outer platforms (24, 26) each having an opening communicating with the inner recess, and the mast (6) passing through said openings and the inner recess and being secured to the casing and connected to the nozzle sector (20). The mast (6) comprises at least one hooking projection having at least one portion extending from a radially outer end (6e) of the mast (6) in a direction away from the centre of the mast (6) and in a plane orthogonal to the radial direction (DR). 本发明涉及具有壳体和喷嘴(2)的涡轮(1)，包括，与壳体刚性地连接的金属外护罩(9)、金属内护罩(5)和形成在金属外护罩(9)和金属
