Abstract
According to the invention, turbine blades are provided that have increased functional reliability, which is achieved in that the interior space (8) of the blade body (3) in the region of the suction-side wall (4), the pressure-side wall (5) and the trailing blade edge (7) has a closed steam-cooling system (9) having at least one cooling passage (10, 27, 28). An open cooling system (11) having at least one cooling passage (14, 15) and a plurality of film-cooling holes (22) which pass through the blade body (3) is formed in the region of the leading blade edge (6).
