Abstract

An assembly for a turbine engine includes a turbine engine first component, a turbine engine second component and a seal assembly. The first component includes a groove and a groove surface. The second component includes a tongue that extends into the groove to a tongue surface. The seal assembly at least partially seals a gap between the groove surface and the tongue surface. The seal assembly includes a rope seal and a clip that attaches the rope seal to the tongue. The rope seal is arranged within the groove between the groove surface and the tongue surface.

First claim

What is claimed is:

1. An assembly for a turbine engine, comprising:
a turbine engine first component including a groove and a groove surface;
a turbine engine second component including a tongue that extends into the groove to a tongue surface; and
a seal assembly at least partially sealing a gap between the groove surface and the tongue surface, the seal assembly including a rope seal and a clip that attaches the rope seal to the tongue;
wherein the rope seal is arranged within the groove between the groove surface and the tongue surface, wherein a plurality of strands of seal element material are arranged together to form the rope seal, and wherein the rope seal and the clip extend circumferentially within the groove at least partially around an axis.

2. The assembly of claim 1 , wherein
the rope seal is engaged axially between the tongue surface and the clip; and
the clip is engaged axially between the rope seal and the groove surface.

3. The assembly of claim 1 , wherein
the groove surface comprises an annular groove surface;
the tongue surface comprises an annular tongue surface; and
the rope seal comprises a substantially full hoop body.

4. The assembly of claim 3 , wherein the clip comprises a substantially full hoop body.

5. The assembly of claim 3 , wherein the clip is one of a plurality of clips that attach the rope seal to the tongue.

6. The assembly of claim 1 , wherein the clip comprises a c-clip.

7. An assembly for a turbine engine, comprising:
a turbine engine first component including a groove and a groove surface;
a turbine engine second component including a tongue that extends into the groove to a tongue surface; and
a seal assembly at least partially sealing a gap between the groove surface and the tongue surface, the seal assembly including a rope seal and a clip that attaches the rope seal to the tongue;
wherein the rope seal is arranged within the groove between the groove surface and the tongue surface;
wherein a plurality of strands of seal element material are arranged together to form the rope seal;
wherein the clip includes a first clamp portion, a second clamp portion and a spring portion that connects the first clamp portion to the second clamp portion;
wherein the tongue is clamped between the first clamp portion and the second clamp portion;
wherein the rope seal is engaged between the tongue surface and the spring portion; and
wherein the spring portion is engaged between the rope seal and the groove surface.

8. The assembly of claim 7 , wherein
the groove surface extends between opposing side groove surfaces; and
the spring portion engages one of the side groove surfaces.

9. The assembly of claim 7 , further comprising a turbine engine third component connected to the first clamp portion.

10. The assembly of claim 9 , wherein
the first component comprises a turbine engine first case;
the second component comprises a turbine engine second case; and
the third component comprises a blade outer air seal arranged within the second case.
