СПОСОБ ИЗГОТОВЛЕНИЯ ЛОПАТКИ И ЭЛЕМЕНТА ГАЗОВОЙ ТУРБИНЫ

摘要

Method for manufacturing a vane ( 1 ) to a gas turbine component intended for guiding a gas flow. The vane ( 1 ) is produced by casting, and 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 hole ( 3 ) for coolant is cut out of the vane, proceeding from the starter hole. A method is also disclosed for manufacturing a gas turbine component including a plurality of vanes ( 1 ) for guiding a gas flow. The gas turbine component is cast in such a way that it includes the vanes and an internal hole ( 3 ) for coolant is then cut out of each of the vanes.
