Abstract

Turbine de turbomachine à distributeur en CMC avec reprise d’effort Turbine comprenant un carter et un distributeur comportant une virole métallique externe (9) solidaire du carter, une virole métallique interne, et une pluralité de secteurs (20) distributeur en CMC formant une couronne s’étendant entre la virole externe (9) et la virole interne, chaque secteur comportant un mât (6), une plateforme intérieure, une plateforme extérieure et au moins une pale présentant un profil creux traversé par le mât (6). Pour chaque pale, la turbine comprend une tôle de maintien (10) comportant une extrémité amont (101) et une extrémité aval (102) selon la direction axiale (DA), et la virole métallique externe (9) comprend au moins une butée radiale (103) s’étendant en saillie axiale depuis ladite extrémité aval (95) vers l’extrémité amont (94), l’extrémité aval (102) de la tôle de maintien (10) étant maintenue radialement entre ladite butée radiale (103) et une face radialement externe (92) de la virole métallique externe (9), et la tôle de maintien (10) étant en appui sur une extrémité radialement externe du mât (6). Figure pour l’abrégé : Fig. 2.Turbomachine turbine with CMC distributor with force take-up Turbine comprising a casing and a distributor comprising an outer metal shroud (9) secured to the casing, an internal metal shroud, and a plurality of CMC distributor sectors (20) forming a crown extending between the outer shroud (9) and the inner shroud, each sector comprising a mast (6), an inner platform, an outer platform and at least one blade having a hollow profile through which the mast (6) passes. For each blade, the turbine comprises a retaining plate (10) comprising an upstream end (101) and a downstream end (102) in the axial direction (DA), and the outer metal shroud (9) comprises at least one radial abutment (103) extending in axial projection from said downstream end (95) towards the upstream end (94), the downstream end (102) of the retaining plate (10) being held radially between said radial stop (103) and a radially outer face (92) of the outer metal shroud (9), and the retaining plate (10) resting on a radially outer end of the mast (6). Figure for abstract: Fig. 2.
