Method for producing a vane, such a vane and a stator component comprising the vane
A method for producing a vane for application in a component in a gas turbine engine includes casting at least one of a vane leading edge part and a vane trailing edge part and connecting the leading edge part and the trailing edge part.
1. A stator component for a gas turbine engine, the component being adapted to be located upstream of a combustion chamber of the gas turbine engine, comprising
an annular inner structure,
an annular outer structure, and
a plurality of circumferentially spaced vanes arranged between the inner structure and the outer structure, wherein gas flow channels are formed between the adjacent vanes, wherein at least one of the vanes is formed by a vane comprising
a cast edge part for at least one of a leading edge part and a trailing edge part, wherein at least one of the leading edge part and the trailing edge part is cast in one piece in a light-weight material by a vacuum high pressure die casting method, and
an attachment for attaching the vane to the outer structure upstream of the combustion chamber of the as turbine engine, in one piece with the cast edge part.
2. A stator component according to claim 1 , wherein it forms an intermediate case for the gas turbine engine.
3. A gas turbine engine wherein it comprises a stator component according to claim 1 .
4. A method for producing a vane for application in a component in a gas turbine engine, the component being adapted to be located upstream of a combustion chamber of the gas turbine engine, comprising
casting a cast edge part for at least one of a vane leading edge part and a vane trailing edge part in a light-weight metal material by a vacuum high pressure die casting method,
connecting the leading edge part and the trailing edge part, and
casting an attachment for attaching the vane to an external structure in one piece with the cast edge pan.
5. A method according to claim 4 , comprising casting the cast edge part with such a shape that it extends along the complete longitudinal edge of the vane.
6. A method according to claim 4 , comprising casting the cast edge part so that it is adapted to be load carrying in a longitudinal direction of the vane.
7. A method according to claim 4 , comprising casting each of the leading edge part and the trailing edge part in one piece.
8. A method according to claim 4 , comprising attaching the leading edge part and the trailing edge part on opposite sides of an intermediate vane part.
9. A method according to claim 6 , comprising forming the intermediate vane part by arranging two plate-shaped portions at a distance from each other, which portions define opposite external surfaces of the vane.
10. A method according to claim 9 , wherein each of the plate-shaped portions comprises a metal sheet.
11. A method according to claim 8 , connecting at least one of the leading edge part and the trailing edge part to the intermediate vane part via welding.
12. A vane for application in a component in a gas turbine engine, the component being adapted to be located upstream of a combustion chamber of the gas turbine engine, comprising
a cast edge part for at least one of a leading edge part and a trailing edge part, wherein the at least one of the leading edge part and the trailing edge part is cast in one piece in a light-weight material by a vacuum high pressure die casting method, and
an attachment for attaching the vane to an external structure in one piece with the cast edge part.
13. A vane according to claim 12 , wherein the cast edge part extends along the complete longitudinal edge of the vane.
14. A vane according to claim 12 , wherein the cast edge part is adapted to be load carrying in the longitudinal direction of the vane.
15. A vane according to claim 12 , wherein each of the leading edge par and the trailing edge part is in one piece.
16. A vane according to claim 12 , wherein the vane comprises an intermediate vane part arranged between the leading edge part and the trailing edge part.
17. A vane according to claim 16 , wherein the intermediate vane part comprises two plate-shaped portions arranged at a distance from each other, which define external surfaces of the vane.
18. A vane according to claim 17 , wherein each of the plate-shaped portions comprises a metal sheet.
19. A vane according to claim 16 , wherein at least one of the leading edge part and the trailing edge part is attached to the intermediate vane part via a weld connection.
