Abstract (en)
[origin: WO9913199A1] The invention relates to a blade (1) for a turbo-machine (11) which is oriented along a blade axis (2). Cross-sectional profiles (5) situated axially at a distance to each other and perpendicular to the blade axis (2) are offset parallel to each other towards the central area (10) in the top end area (4) and in the base end area (3) of the blade (1) in such a way that the blade (1) is displaced along the blade axis (2) in a convex manner. In addition, cross-sectional profiles (5a, 5b; 15a, 15b) situated at an axial distance to each other are twisted in relation to each other in the base end area (3) and/or the top end area (4). The invention further relates to a steam turbine (11).
