Abstract: An arrangement of a plurality of cooling channels within a turbine blade conveys cooling fluid, wherein the cooling channels lead through the turbine blade, which has a blade root, a blade tip, a leading edge, and a trailing edge, to one or more cooling-fluid outlets, wherein the cooling channels are connected to each other at selected locations and extend separately from each other in other regions in such a way that, in the event of damage to the turbine blade in the region of one cooling channel, the cooling by the other cooling channels remains largely unimpaired, wherein at least one cooling channel begins in a region near the leading edge and near the blade root and leads as a diagonal channel through the turbine blade into a region near the trailing edge and near the blade tip.

Abstract: A sealing element for sealing a gap between two components, which can thermally move relative to each other and each have two substantially parallel component grooves, wherein the sealing element is directed along a main line and has, in a cross section substantially perpendicular to the main line, a first and second end segment and a middle region arranged between the end segments, to ensure an effective seal in the event of thermal expansions of the components that are comparatively large radially and to reduce thermal stresses and crack formations on the components. A third end segment having substantially the same extension direction as the first end segment is arranged on the middle region in parallel with the first end segment and a fourth end segment having substantially the same extension direction as the second end segment is arranged on the middle region in parallel with the second end segment.
