Abstract
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.
