Abstract (en)

[origin: WO9954597A1] The invention relates to a cast turbine blade (1), comprising a blade (5) and a platform area (7), especially a gas turbine guide blade. The platform area (7) is formed by a hot gas platform (9) on the hot gas side and an opposite load platform (11). The load platform (11) absorbs the forces enabling a thin configuration of the hot gas platform (9). Particularly little heat stress occurs.
