Abstract: A process for producing a groove-like recess which is part of a strip seal between two components which enclose a gap, uses a material-removing process technology to create the groove-like recess in the two components in such a manner that the groove-like recess in each of the two components, after orientation with respect to one another, lie substantially opposite one another in an end position in which they enclose the gap between them, and that a strip element can be introduced into the groove-like recesses in such a manner that the strip element at least partially projects into both groove-like recesses and, under the action of a force, forms a substantially gastight joint with the groove-like recesses in the two components. Furthermore, a groove-like recess of this type is part of a strip seal.

Abstract: Described is a device and a method for cooling a platform of a turbine blade comprising a blade root, a vane with a leading and trailing edge, as well as a blade tip with a platform, through which platform extends radially, at least in part, at least one cooling channel that is connected with at least one outlet channel exiting via an outlet opening at the platform. The invention is characterized in that the outlet channel has, adjacent to the outlet opening, a longitudinal channel direction that extends, in projection, longitudinally to the turbine blade in an essentially co-parallel manner with respect to the flow direction of a local flow field of a mass flux relatively passing by the turbine blade, said flow field directly flowing over the exit opening.
