Turbine vane for a stationary gas turbine

The invention relates to a turbine vane (10) for a stationary gas turbine comprising a hollow vane blade (24) inside of which at least one rib (36) is provided to allow the pressure side wall (26) and the suction side wall (28) to support one another, said rib having an opening (40) penetrating the...

Beschreibung
Zusammenfassung:	The invention relates to a turbine vane (10) for a stationary gas turbine comprising a hollow vane blade (24) inside of which at least one rib (36) is provided to allow the pressure side wall (26) and the suction side wall (28) to support one another, said rib having an opening (40) penetrating the rib (36) near the wall at the height of the external fillet (34) between the side wall (26), (28) and the platform surface (20) for the purposes of extending the life of the turbine vane (10). By means of the opening (40), material accumulations in the transition region are avoided or the accumulation is reduced in comparison to that without the opening (40), whereby increases in stiffness and higher temperature gradients associated therewith can be avoided.
