Rotor blade for an axial flow turbomachine

摘要

The blade (10) has a platform (14) with a dovetail-shaped blade base (16) that includes two opposing side walls (20, 22). The walls diverge from the Platform to a blade base lower side (18). A longitudinal axis of the rotor blade is arranged perpendicular to a platform surface in a region of a connection between a curved shovel blade (12) and the platform. The walls are curved along an extension between the platform and the lower side in same direction, such that blade base-center line (24) is curved in corresponding direction and is centrically arranged between the walls.
