Abstract

Eine erfindungsgemässe Turbinenschaufel (1) mit Kanälen im Inneren weist im Bereich eines radialen Endes (49) einer Trennwand (31,34), die einen Kanal (16,19) begrenzt, einen Absatz (25,28) auf, auf dem ein Einsatz (40) aufliegt, der den zumindest einen Kanal (16,19) verschliesst, so dass das bereits hergestellte strömungstechnisch optimierte Ende einer Trennwand erhalten bleibt.

Figure 00000001
A turbine blade (1) according to the invention with channels in the interior has, in the region of a radial end (49) of a partition wall (31, 34), which delimits a channel (16, 19), a step (25, 28) on which an insert (40) rests, which closes the at least one channel (16,19), so that the already prepared aerodynamically optimized end of a partition wall is maintained.
