Abstract

A coolable blade for a gas turbine or the like, having a blade body and a blade root, in which case the blade body is composed of a suction-side wall and a pressure-side wall, which, while forming a cavity, are connected via a leading edge, at least partly via a trailing edge and via a blade tip, the cavity is subdivided by essentially radially running separating webs into passages which form a continuous, repeatedly deflected flow path for a cooling medium, at least one blow-out opening is provided for the cooling medium, and the separating web adjacent to the trailing edge has one or more through passages close to the blade tip.
