Abstract

An assembly for a turbine engine comprising a plurality of circumferentially arranged segments having first and second confronting end faces. The first and second confronting end faces include a multi-channel spline seal assembly. The multi-channel spline seal assembly includes at least a first and second channel wherein confronting first or second channels can receive at least one spline seal.

First claim

What is claimed is:

1. A turbine engine having a longitudinal axis comprising:
a stator component disposed about the longitudinal axis, and comprising a plurality of circumferentially arranged component segments having confronting pairs of circumferential ends; and
a multi-channel spline seal comprising:
a first set of first and second channels located in one of the circumferential ends, the first and second channels intersecting to form an intersection, the first channel having a first depth at the intersection, the second channel having a second depth at the intersection, and the second depth being greater than the first depth to define a ledge adjacent the first channel; and
a spline seal located within the second channel and having a width at the intersection such that the spline seal at least partially covers the first channel and at least partially overlies the ledge.

2. The turbine engine of claim 1 wherein the multi-channel spline seal comprises a second set of first and second channels in the other of the circumferential ends to define confronting pairs of first channels and second channels.

3. The turbine engine of claim 2 wherein the spline seal is located within the confronting pair of second channels.

4. The turbine engine of claim 3 wherein the second channel of the second set has a first depth greater than the second depth of the first channel of the second set to define another ledge.

5. The turbine engine of claim 4 wherein the spline seal covers the confronting pair of first channels and at least partially overlies both ledges at the intersection.

6. The turbine engine of claim 4 wherein the confronting pair of second channels have corresponding back walls or lower back junctions, and the spline seal has a width at the intersection that is at least greater than a first dimension from one of the back walls or the lower back junctions to an edge of the confronting ledge.

7. The turbine engine of claim 6 wherein a second dimension is defined between the corresponding back walls or the lower back junctions and the width of the spline seal at the intersection is between the first and second dimensions.

8. The turbine engine of claim 1 wherein at least one of the first and second depths is constant for the length of the corresponding at least one first and second channel.

9. The turbine engine of claim 1 wherein the intersection is located at a terminal end of at least one of the first and second channels.

10. The turbine engine of claim 1 wherein the intersection is located at an interim point of at least one of the first and second channels.

11. The turbine engine of claim 1 wherein the first and second channels intersect at a non-right angle.

12. The turbine engine of claim 1 wherein the stator comprises at least one of a shroud, vane, nozzle, nozzle body, combustor, or hanger.

13. The turbine engine of claim 1 wherein the first set of first and second channels comprises multiple first channels, each forming an intersection with the second channel.

14. A component for a turbine engine comprising:
a plurality of circumferentially arranged component segments having confronting pairs of circumferential ends; and
a multi-channel spline seal comprising:
a first set of first and second channels located in one of the circumferential ends, the first and second channels intersecting to form an intersection, the first channel having a first depth at the intersection, the second channel having a second depth at the intersection, and the second depth being greater than the first depth to define a ledge adjacent the first channel; and
a spline located within the second channel and having a width at the intersection such that the spline at least partially covers the first channel and at least partially overlies the ledge.

15. The turbine engine of claim 14 wherein the multi-channel spline seal comprises a second set of first and second channels in the other of the circumferential ends to define confronting pairs of first channels and second channels.

16. The turbine engine of claim 15 wherein the spline is located within the confronting pair of second channels.

17. The turbine engine of claim 16 wherein the second channel of the second set has a depth greater than the depth of the first channel of the second set to define another ledge.

18. The turbine engine of claim 17 wherein the spline at least partially covers the confronting pair of first channels and at least partially overlies both ledges at the intersection.

19. The turbine engine of claim 17 wherein the second channels have corresponding back walls or lower back junctions, and the spline has a width at the intersection that is at least greater than a first dimension from one of the back walls or the lower back junctions to an edge of the confronting ledge.

20. The turbine engine of claim 19 wherein a second dimension is defined between the corresponding back walls or the lower back junctions and the width of the spline at the intersection is between the first and second dimensions.
