Abstract: Rotor having of rotor blades. Every rotor blade has a blade body and coupling segment. A width of the coupling element segment is defined in circumferential direction by edges extending in axial direction. The coupling segment is contoured at a first side such that, on the flow inlet side to a flow inlet edge, the radially outer edge projects beyond the radially inner edge in axial direction. At this side on the flow outlet side of the blade body, the radially inner edge projects beyond the radially outer edge. The coupling segment is contoured at a second side such that, adjacent on the flow outlet side to the flow outlet edge, the radially outer edge extending in axial direction projects beyond the radially inner edge in axial direction. At, this second side facing away from the flow inlet edge the radially inner edge projects beyond the radially outer edge.

Abstract: A rotor of a turbomachine has a rotor base body and a plurality of rotor blades. Every rotor blade has a blade body and a coupling element segment. The coupling element segment of every rotor blade is contoured at a first side and at a second side opposite the first side that, at the first side and at the second side, a radially outer edge of the respective coupling element segment extends substantially in axial direction and a radially inner edge of the respective coupling element segment extends substantially in axial direction respectively delimit two surfaces separated from one another by a separating line. In at least one circumferential position of the rotor between two directly adjacent rotor blades, the separating lines run approximately parallel to, or in alignment with, the mounting direction of the rotor blades at the rotor base body, which mounting direction is defined by the blade roots.

Abstract: Labyrinth seal for a turbomachine having a plurality of elongated seal blades arranged along a longitudinal direction of the labyrinth seal next to one another and at a distance from one another so that a chamber is formed between adjacent seal blades. The seal blades each have a free end and at least one seal wall extending in longitudinal direction of the labyrinth seal. A seal gap is formed between each free end and the seal wall, adjacent chambers being in fluid communication with one another by the seal gap so that a working fluid impinging on the labyrinth seal can flow through the labyrinth seal in a throttled manner in a throttling direction proceeding from a first seal blade to a final seal blade. A fluid discharge device is provided that is arranged to bring about a continuous reduction in a specific enthalpy of the working fluid by discharging working fluid from the labyrinth seal along the throttling direction.
