| 摘要 |
The invention relates to a hollow turbine blade, having an airfoil profile which is formed by a suction-side profile wall and a pressure-side profile wall and around which a hot gas can flow and which has a profile height, directed along a blade axis, from a platform up to a profile tip, having at least one supporting rib which is provided in the interior of the turbine blade and connects the pressure-side profile wall to the suction-side profile wall in a respective connecting region, and having at least one slot provided in the profile wall on the hot-gas side and extending along the blade axis. In order to specify a turbine having an especially long service life, it is proposed that the slot, on the hot-gas side in the profile wall, be opposite the connecting region formed by the supporting rib and the profile wall.
