Claims
- 1. A method for manufacturing a gas turbine component, said method comprising:
casting a vane configured for guiding a gas flow; and cutting out an internal hole in the vane for coolant.
- 2. The method as recited in claim 1, further comprising:
providing the vane with a starter hole, and cutting out the internal hole for coolant by proceeding from the starter hole.
- 3. The method as recited in claim 2, further comprising:
casting the starter hole into the vane.
- 4. The method as recited in claim 2, further comprising:
machining the starter hole into the vane.
- 5. The method as recited in claim 2, further comprising:
cutting out of the coolant hole by wire electrodischarge machining.
- 6. The method as recited in claim 1, further comprising:
cutting out the coolant hole so that a surface of the vane that defines the coolant hole has, at least in part, an area with alternating elevations and depressions.
- 7. The method as recited in claim 1, further comprising:
providing the vane with at least one recess in proximity to a rear end thereof, and which is connected to the internal hole for coolant.
- 8. The method as recited in claim 7, further comprising:
connecting the recess to the internal hole for coolant during the cutting out of the internal hole.
- 9. The method as recited in claim 7, further comprising:
locating the recess at the rear end of the vane during casting.
- 10. The method as recited in claim 7, further comprising:
providing a vane holder structure; and fitting a plurality of the manufactured vanes into the vane holder structure and thereby establishing a multi-vane gas turbine component.
- 11. The method as recited in claim 10, further comprising:
cast manufacturing the vane holder structure.
- 12. A method for manufacturing a gas turbine component comprising a plurality of vanes for guiding a gas flow, the method comprising:
casting a gas turbine component to include a plurality of vanes; and cutting an internal hole for coolant out of each of the vanes, post casting.
- 13. The method as recited in claim 12, further comprising:
providing each of the plurality of vanes with a starter hole, and cutting out the internal holes for coolant by proceeding from the starter hole.
- 14. The method as recited in claim 13, further comprising:
casting the starter hole into each of the plurality of vanes.
- 15. The method as recited in claim 13, further comprising:
machining the starter hole into the vane.
- 16. The method as recited in claim 13, further comprising:
cutting out of the coolant holes by wire electrodischarge machining.
- 17. The method as recited in claim 12, further comprising:
cutting out the coolant holes so that a surface of each of the plurality of vanes that defines respective coolant holes has, at least in part, an area with alternating elevations and depressions.
- 18. The method as recited in claim 12, further comprising:
providing each of the plurality of vanes with at least one recess in proximity to a rear end thereof, and which is connected to the internal hole in the particular vane for coolant.
- 19. The method as recited in claim 18, further comprising:
connecting, in each of the plurality of vanes, a respective recess to an associated internal hole for coolant during the cutting out of the internal hole.
- 20. The method as recited in claim 18, further comprising:
locating, in each of the plurality of vanes, a respective recess at the rear end of the respective vane during casting.
