<p>The turbine blade (12) is provided with a blade sheet (10), in which the coolant (34) permeable areas (23,24,25,26) of cavities (21,22) are separated from each other by the partition walls (28,29,31). The passages (40,42) fluidically connecting the areas are provided in the partition walls. The passages have a longitudinal segmented contour or orientation, which hinders the flow of coolant or the inflow of cooling air through the passages, compared to a straight passage extending perpendicular through the partition walls. An independent claim is also included for a cast core for use in a casting device.</p> |
