| 摘要 |
The invention relates to a turbine blade (1) with a blade (2), a blade root (3), and a cover plate (14) between the blade root (3) and the blade (2). The cover plate (14) has a parallelogram (42) with a front surface (40) and a rear surface (41) and a first bearing surface (43) and a second bearing surface (44). The blade (2) has a profiled design and a leading edge (45) and a trailing edge (46), said leading edge (45) pointing towards the front surface (40) and said trailing edge (46) pointing towards the rear surface (41). The front surface (40) has a curvature (20) in at least some sections in order to prevent a plastic deformation during operation. |
