Abstract

The turbine blade has a blade basic body (30), whose external surface (32,36) is provided in the leading edge area with heat shield element (22) arranged at a distance from blade basic body. The multiple auxiliary cooling channels (24) branch off from a main cooling channel (26), which is formed in blade body, in which auxiliary cooling channels open into outlet openings in leading edge area of blade body. The shield element has multiple outlet channels (28) arranged behind one another in longitudinal direction and extend from main cooling channel to the outer wall face of the shield element.
