(54)Turbine blade


(57) The present invention relates to a blade (1) for a turbine (7), wherein the blade comprises a platform (2) supporting an airfoil (4) of the blade (1) on a top plate (3) of the platform (2). The platform (2) moreover comprises a front wall (10), which in particular faces an upstream neighbouring vane (47), when assembled into a turbine (7). An improved efficiency of the turbine (7) can be achieved if the front wall (10) of the blade (1) is fitted with a flat section (26) running perpendicular to the top plate (3).
The invention moreover relates to a rotor (6) as well as to a turbine (7), both comprising at least such a blade (1)
