The blades (2, 4) have a blade root (8), a blade neck (10) and a platform (14) arranged between the neck and a blade pan (12). The platform has a front projection (16) and a rear projection (18), where cool cooling air stream is delimitable from hot gas stream by the projections. The blade neck has cooling channels (30, 32, 34) for guiding air stream. The cooling channels have an extended section between an inlet (50) and an outlet, and a turbulator (60) is arranged in the section. The turbulator is arranged at a distance from a channel axis (58) extending between the inlet and the outlet. |
