Abstract (en)

[origin: EP0321825A2] In this case, the rotor blades are intended to be arranged with their feet in axial slots of a rotor disc and intermediate spaces, extending in the axial and circumferential direction, are constructed between the foot plates of the blades and the rotor disc surface; between sections of the blades and the rotor disc it is intended to construct component covers on the intermediate spaces, with which the blades are fixed axially in one direction on the rotor disc; in this case, component covers may be constructed from geometrically intersecting outline or loop contours of the blade feet and outline or spatial contours of the rotor disc.
