Abstract (en)

[origin: EP2644829A1] The turbine blade (10) has a blade body (11) formed by a leading edge (13) and a trailing edge (14). The blade body merges in a blade root (16) designed for attachment of the turbine blade through a shaft (15). A platform (17) is arranged at the lower end of the blade body for defining a flow channel, and is designed as a separately formed component. The platform is connected to the blade body in a form-fit manner. The platform has multiple individual platform elements (17a,17b) which enclose the blade body in an assembled state.
