Abstract

Kühlung einer Turbinenschaufel mittels eines geschlossenen und eines offenen Kühlsystems, dies wird dadurch erreicht, dass der Innenraum (8) des Schaufelkörpers (3), im Bereich der saugseitigen Wand (4), der druckseitigen Wand (5) und der Schaufelaustrittskante (7) ein geschlossenes Dampfkühlsystem (9) mit zumindest einem Kühlkanal (10,27,28) aufweist. Im Bereich der Schaufeleintrittskante (6) ist dagegen ein offenes Kühlsystem (11) mit zumindest einem Kühlkanal (14,15) und mehreren den Schaufelkörper (3) durchdringenden Filmkühllöchern (22) ausgebildet.

Figure 00000001
Cooling of a turbine blade by means of a closed and an open cooling system, this is achieved in that the interior (8) of the blade body (3), in the area of the suction-side wall (4), the pressure-side wall (5) and the blade outlet edge (7) Has closed steam cooling system (9) with at least one cooling channel (10,27,28). In the area of the blade leading edge (6), on the other hand, an open cooling system (11) with at least one cooling channel (14, 15) and a plurality of film cooling holes (22) penetrating the blade body (3) is formed.
