Abstract (en)
[origin: EP0707136A1] At least the first blade groove (10) on the work medium entry side is axially asymmetrically formed by several radii (R1-R4). The first radius (R1) is larger than that following (R2) and the circular arcs (21-24) formed by the radii have a common tangent (T) at their contact points. The blade feet (3) are hammer-shaped. The forces occurring during operation are introduced into the rotor via support points (5) of the blade groove. On the contour of the part of the blade groove described by the radii specific points (A-E) are defined. These points divide the steam entry side contour into circular arcs described by the radii.
