Abstract
A turbine blade with aerodynamic aerofoil, which extends from a bottom to a top end and has two aerofoil walls extending between, which transversely thereto extend from a common leading to a common trailing edge, and with at least one platform, which extends transversely in relation to the aerofoil and is arranged at one of the two ends of the aerofoil. A number of openings are provided in the trailing edge between the bottom end and the top end. Either the opening in the trailing edge arranged closest to the platform surface extends into the platform surface or the platform surface facing the aerofoil is lowered locally in the region of that opening that is closest to the platform, and the opening opens out into a portion of the trailing edge that has become free as a result of the lowering.
