Abstract

La structure comprend des aubes fixes 27a, 27b disposées circonférentiellement à la machine, une paroi latérale supérieure 5 et une paroi latérale inférieure 6 auxquelles lesdites aubes fixes sont fixées respectivement par leurs bouts et par leurs bases, un trajet d'écoulement annulaire étant défini entre les surfaces extérieures des aubes fixes et des parois latérales. Chaque aube fixe a une forme de section droite telle que son épaisseur t, T augmente dans la direction d'une surface 24 de la paroi latérale supérieure, à partir d'un point de hauteur arbitrairement choisi h par rapport à une surface 23 de la paroi latérale inférieure, grâce à quoi la section d'une gorge, pour chaque partie de l'aube fixe, peut varier suivant sa hauteur. Turbine à vapeur, turbines à gaz, compresseurs axiaux, etc.
