Abstract

A laminated sheet for a gas turbine component, the laminated sheet has a first cover layer, a second cover layer and a first intermediate layer, wherein the first cover layer, the second cover layer and the first intermediate layer are stacked together on top of each other. The first intermediate layer is located between the first cover layer and the second cover layer. The first intermediate layer has at least one first elongated through hole, wherein a cooling fluid is flowable through the first elongated through hole.

First claim

1 . A laminated sheet for a gas turbine component, the laminated sheet comprising
a first cover layer, a second cover layer, and a first intermediate layer, wherein the first cover layer, the second cover layer and the first intermediate layer are stacked together on top of each other, wherein the first intermediate layer is located between the first cover layer and the second cover layer, wherein the first intermediate layer comprises at least one first elongated through hole through which a cooling fluid is flowable, wherein the first intermediate layer comprises at least one further first elongated through hole which is spaced apart from the first elongated through hole, wherein the cooling fluid is flowable through the further first elongated through hole, wherein the first elongated through hole and the further first elongated through hole are connected such that the cooling fluid is flowable between the first elongated through hole and the further first elongated through hole.

2 . The laminated sheet according to claim 1 , further comprising
a second intermediate layer, wherein the first cover layer, the second cover layer, the first intermediate layer and the second intermediate layer are stacked together on top of each other, wherein the second intermediate layer is located between the first intermediate layer on the one side and the first cover layer or the second cover layer on the other side, wherein the second intermediate layer comprises at least one second elongated through hole through which the cooling fluid is flowable.

3 . The laminated sheet according to claim 2 ,
wherein the first elongated through hole and the second elongated through hole are parallel with respect to each other.

4 . The laminated sheet according to claim 2 ,
wherein the first elongated through hole extends along a first direction and the second elongated through hole extends along a second direction, wherein the first direction and the second direction are non-parallel, with respect to each other.

5 . The laminated sheet according to claim 4 ,
wherein the first elongated through hole and the second elongated through hole overlap each other at an overlapping region, such that the cooling fluid is flowable between the first elongated through hole and the second elongated through hole.

6 . The laminated sheet according to claim 1 ,
wherein the first cover layer comprises a first through hole, wherein the first cover layer is aligned with respect to the first intermediate layer such that the cooling fluid is flowable between the first through hole and the first elongated through hole.

7 . The laminated sheet according to claim 6 ,
wherein the first cover layer comprises a further first through hole which is spaced to the first through hole, wherein the first cover layer is aligned with respect to the first intermediate layer such that the cooling fluid is flowable between the further first through hole and the first elongated through hole.

8 . The laminated sheet according to claim 1 ,
wherein the second cover layer comprises a second through hole, wherein the second cover layer is aligned with respect to the first intermediate layer such that the cooling fluid is flowable between the second through hole and the first elongated through hole.

9 . The laminated sheet according to claim 8 ,
wherein the second cover layer comprises a further second through hole which is spaced to the second through hole, wherein the second cover layer is aligned with respect to the first intermediate layer such that the cooling fluid is flowable between the further second through hole and the first elongated through hole.

10 . The laminated sheet according to claim 1 ,
wherein the first elongated through hole and the further first elongated through hole are parallel or non-parallel, with respect to each other.

11 . The laminated sheet according to claim 1 ,
wherein the first intermediate layer comprises a plurality of further first elongated through holes which are spaced apart from each other and from the first elongated through hole.

12 . The laminated sheet according to claim 1 ,
wherein the first cover layer comprises a fluid guiding element, wherein the fluid guiding element extends from the first cover layer into the first elongated through hole for guiding the cooling fluid within the first elongated through hole.

13 . The laminated sheet according to claim 1 ,
wherein the first cover layer comprises a first material, and wherein the first intermediate layer, the second intermediate layer and/or the second cover layer comprise a second material.

14 . A turbine component, comprising
a laminated sheet according to claim 1 .

15 . The turbine component of claim 14 ,
wherein the turbine component comprises a combustion chamber or a guide vane nozzle.

16 . The laminated sheet according to claim 4 ,
wherein the first direction and the second direction are perpendicular with respect to each other.

17 . The laminated sheet according to claim 10 ,
wherein the first elongated through hole and the further first elongated through hole are perpendicular with respect to each other.

18 . The laminated sheet according to claim 13 ,
wherein the first material comprises an oxidation resistant material, and wherein the second material comprises a corrosion resistant material.
