Abstract (en)

[origin: EP2597266A1] The blade (1) has a blade root (2), a blade leaf (4) and a blade neck (6) arranged between the blade root and the blade leaf, where the blade neck forms an inner platform (14). The blade neck has a front sealing wall (30) and a rear sealing wall (32), where the rear wall limits a triangular inner area (28) with the platform. The inner area is radially tapered from outside to inside. The platform has front and rear projections (16, 18) in a flow direction, and the blade neck is designed as a rod with lateral pockets, where the walls extend from a passage area of the projections to the neck.
