Abstract
A rotor of a turbine-type machine, in particular a gas turbine rotor, is disclosed. The rotor has a rotor base body, where the rotor base body has a groove extending in the circumferential direction of the rotor base body, and has multiple rotor blades or rotor blade segments. The rotor blades or rotor blade segments are each anchored in the groove extending in the circumferential direction of the rotor base body by a blade base. The groove has a profiled groove wall leg on only one side, with the blade base of the rotor blades or the rotor blade segments being in contact with the profiled groove wall leg with a correspondingly profiled supporting flank.

A rotor of a turbine-type machine, in particular a gas turbine rotor, having a rotor base body, wherein the rotor base body has a groove extending in a circumferential direction of the rotor base body, and having multiple rotor blades or rotor blade segments, wherein the rotor blades or rotor blade segments are each anchored by a blade base in the groove of the rotor base body, wherein the groove has a profiled groove wall leg on only one side and wherein a profiled supporting flank of the blade base of the rotor blades or the rotor blade segments is in contact with the groove wall leg.
A rotor of a turbine-type machine, comprising:
- a rotor base body, wherein a groove is defined between a profiled wall leg of the rotor base body and an unprofiled rib of the rotor base body and wherein the groove extends in a circumferential direction of the rotor base body;
- and
- a rotor blade having a base, wherein the base includes a profiled supporting flank;
- wherein the base is secured in the groove with the profiled wall leg of the rotor base body contacting the profiled supporting flank of the rotor blade base.
A method for securing a rotor blade of a turbine-type machine to a rotor base body, wherein a groove is defined between a profiled wall leg of the rotor base body and an unprofiled rib of the rotor base body and wherein the groove extends in a circumferential direction of the rotor base body, and further wherein the rotor blade has a base that includes a profiled supporting flank, comprising the steps of:
- placing the rotor blade base in the groove of the rotor base body;
- and
- engaging the profiled supporting flank of the rotor blade base with the profiled wall leg of the rotor base body.
