Abstract (en)
The turbine blade (2) has a blade leaf (12) with ducts (22) for passing coolant (K), outlet ports (24) which are arranged parallel to a leading edge (14), and outlet duct which is oblique with respect to longitudinal direction (L) of blade. The transitional points at which the orientation of the outlet ducts changes, are offset relative to one another in the longitudinal direction for two adjacent rows.
