Abstract
A turbine blade through which cooling liquid flows, comprises several flow channels that are adjacently arranged in the flowing-off direction of the working fluid. The flow channels extend between inflow openings, which are located on a radially inner blade foot, and out-flow openings, which are situated opposite the blade foot in a more radially outer manner. The flow channels extend such that the local radial flow components of the resulting cooling fluid stream are directed outward in a, for the most part, predominately radial manner. A flow channel, which is in the front when viewing in the flowing-off direction, is provided whose outflow openings are placed inside a touching edge of the turbine blade. In addition, at least one rear edge channel is provided whose associated resulting cooling fluid stream additionally comprises local cross-flow components and whose outflow openings are placed inside a rear edge of the turbine blade.
