Disclosed is a rotor blade (1) for a gas turbine (100), said rotor blade comprising an aerofoil (2) having a pressure side (10) and an intake side (12) which transition into a platform (14) to which an attachment region (16) is connected, said region having a fir tree spring (18) which has a plurality of lateral toothed extensions (20, 22, 24, 26, 28, 30) arranged on the pressure side (10) and the intake side (12), which extensions extend in an azimuthal direction. Said rotor blade should enable increased efficiency at the same time as an increased service life of the gas turbine and its components to be achieved. In addition, the azimuthal extent of one lateral toothed extension (20, 22, 24) is reduced in an axial region of said lateral toothed extension (20, 22, 24), in which region the pressure load during operation exceeds a predefined threshold. |
