Rotor of a turbomachine

A rotor of a turbomachine comprising:

• a main rotor body;
• and
• a plurality of rotor blades, each rotor blade having:
• a blade root, wherein each rotor blade is fastened by its blade root to the main rotor body;
• a blade body;
• and
• at least one coupling element segment in the region of a blade body, wherein a width of the coupling element segment of each rotor blade is defined in circumferential direction by edges extending substantially in axial direction,
• wherein viewed from radially outside, the at least one coupling element segment, of every rotor blade is contoured such that at a first side to which a coupling element segment of a first directly adjacent rotor blade is connected considered in circumferential direction and
• adjacent to a flow inlet side a flow inlet edge of the blade body of the respective rotor blade a radially outer edge of the coupling element segment, which radially outer edge extends substantially in axial direction, projects outwardly in circumferential direction beyond a radially inner edge of the respective coupling element segment, the radially inner edge extends substantially in axial direction,
• whereas, at the first side facing away from the flow outlet side from a flow outlet edge of the blade body of the respective rotor blade, the radially inner edge extending substantially in axial direction projecting outwardly in circumferential direction beyond the radially outer edge extending substantially in axial direction, and
• the coupling element segment of each rotor blade is contoured such that a second side located opposite the first side, to which second side the coupling element segment of a second directly adjacent rotor blade is connected considered in circumferential direction, adjacent on the flow outlet side to the flow outlet edge of the blade body of the rotor blade,
• the radially outer edge of the respective coupling element segment extends substantially in axial direction and projects outwardly in circumferential direction beyond the radially inner edge of the respective coupling element segment, the radially inner edge extends substantially in axial direction,
• whereas, at the second side facing away on the flow inlet side from the flow inlet edge of the blade body of the respective rotor blade, the radially inner edge extending substantially in axial direction projects outwardly in circumferential direction beyond the radially outer edge extending substantially in the axial direction.
