The invention relates to a novel reworking of a geometric shape of a stator vane in order locally to reduce the stress levels. It proposes a novel type of stator section in which a local reworking of the geometry of the vanes has been performed, this reworking making it possible to reduce the level of stress in the brazed joint connecting the vane to its outer shroud without entailing further aerodynamic engineering. To do that, the invention consists in a progressive and localized increase in the radius at the trailing edge combined with a progressive increase in the thickness of the vane.

Stator vane with localized reworking of shape, stator section, compression stage, compressor and turbomachine comprising such a vane

A variable-setting stator blade guidance device of an axial turbomachine is provided. The blade includes an airfoil, a platform and a pivot mounted in the casing of the turbomachine. The device includes a bearing integrated into the platform. In particular, the device includes a bush sandwiched between the platform and the casing, and the integrated bearing is formed between the bush and the platform. In particular, the bush includes a cylindrical surface portion on the side of the platform cooperating with a matching cylindrical surface portion on the platform to form the integrated bearing.
