摘要： Turbine stage comprising a fixed rack (204) followed by a moving rack (205) comprising blades (206, 207) mounted between a floor (201, 211) and a ceiling (202, 212). The surfaces of the ceiling (202, 212) and/or the floor (201, 211) admit as the meridian line sine curves of which the maximum for that of the ceiling (202, 212), the maximum or the minimum for that of the floor (201, 211) are in the inter-rack plane. The curvature of this sine curve at the outlet of the fixed rack (204) is calculated so as to make the tangential and radial static pressure gradients at the ceiling and/or the floor at the outlet of the fixed rack (204) equal. The disturbances are confined in restricted areas, which improves the output of the stage.

摘要： An assembly (1) of at least two members. One of the members (10; 20) supports the other member (20; 10), the assembly defining an axial direction (x), a radial direction (r), and a circumferential direction, an inner member (20) of said at least two members being received radially inside an outer member (10) of said at least two members, wherein the inner member and the outer member are attached to each other by a support arrangement, the support arrangement comprising at least one floating support assembly (40), wherein the floating support assembly provides a displaceable coupling between an inner member support point provided at the inner member and an outer member support point provided at the outer member. The floating support assembly (40) is arranged and configured to provide for a guided relative displacement between the inner member support point and the outer member support point along a displacement path (43), wherein the displacement path (43) of the relative displacement is inclined with respect to the axial direction (x) as well as to the radial direction (r) at a nonzero angle (Θ), such that a relative displacement of the support points in the radial direction results in an interrelated relative displacement of the support points in the axial direction and vice versa.

摘要： Etage de turbine comportant une grille fixe (204) suivi d'une grille mobile (205) comportant des aubes (206, 207) montees entre un plancher (201, 211) et un plafond (202, 212). Les surfaces du plafond (202, 212) et/ou du plancher (201, 211) admettent pour meridienne des sinusoides dont le maximum pour celle du plafond (202, 212), le maximum ou le minimum pour celle du plancher (201, 211) se situent dans le plan intergrille. La courbure de cette sinusoide a la sortie de la grille fixe (204) est calculee de facon a obtenir l'egalite entre les gradients de pression statique tangentiel et radial au plafond et/ou au plancher a la sortie de la grille fixe (204). Les perturbations sont confinees dans des zones restreintes ce qui ameliore le rendement de l'etage.
