A METHOD FOR MANUFACTURING A VANE TO A GAS TURBINE COMPONENTAND A METHOD FOR MANUFACTURING A GAS TURBINE COMPONENT

摘要

The invention relates to a method for manufacturing a vane (1) to a gas turbine component, which vane is intended for guiding a gas flow, the vane ( 1) being produced by casting. An internal hole (3) for coolant is then cut out of the cast vane (1). The vane (1) is provided with a starter hole (5), either during casting or once casting is completed, following which the internal ho le (3) for coolant is cut out of the vane, proceeding from the starter hole. Th e invention also relates to a method for manufacturing a gas turbine component comprising a plurality of vanes (1) for guiding a gas flow. The gas turbine component is cast in such a way that it comprises said vanes and an internal hole (3) for coolant is then cut out of each of the vanes in the manner stat ed above.
