Securing module for axial securing of a root of a turbo engine blade

摘要

The securing unit (20) i.e. securing plate, has a partially curved outer contour (24) facing toward a groove wall that is designed as a groove base (33). The outer contour includes different radii (R1-R3), where the first radius is arranged between the second and third radii, and the second radius is larger than the first and third radii. A section of the outer contour forms a securing unit-contact region (21) that is arranged in contact with a groove contact region (31) of the groove wall, where the securing unit includes an elastic material.
