Abstract
A blade () for a gas turbine has a blade airfoil (), the blade wall () of which encloses an interior space (). For cooling the blade wall (), the blade wall () includes a cooling arrangement () which has a radial passage () extending in the longitudinal direction of the blade and from which a multiplicity of cooling passages (), extending in the blade wall (), branch in the transverse direction, and from which a multiplicity of film-cooling holes () are led to the outside in the transverse direction. Particularly efficient cooling is made possible by the distribution of the film-cooling holes () along the radial passage () being selected independently of the distribution of the cooling passages () along the radial passage ().
