Abstract: A turbine stage for a turbine engine, the stage including a nozzle and a wheel mounted inside a sectorized ring carried by a casing. The nozzle is attached to the casing and is retained axially downstream by bearing against an annular split ring. Each ring sector includes at its upstream end a member of C-shaped section that is engaged on the casing rail and that holds the split ring radially. A radially inner wall of the C-shaped member of each ring sector extends inside the split ring over an entire axial dimension thereof and its upstream end portion is engaged in at least one recess of the nozzle.
Abstract translation: 一种用于涡轮发动机的涡轮级，该级包括一个喷嘴和一个安装在由壳体承载的扇形环内的轮。 喷嘴连接到壳体并且通过承受环形裂环而轴向保持在下游。 每个环形扇区在其上游端包括C形截面的构件，其接合在壳体轨道上并且径向保持开口环。 每个环形扇形体的C形构件的径向内壁在整个轴向尺寸上在开口环的内部延伸，并且其上游端部接合在喷嘴的至少一个凹部中。
