Claims12
A turbomachine comprising:
- a first component comprising a first seal slot with a first corner;
- a second component coupled to the first component, wherein the second component comprises a second seal slot with a second corner;
- a gap between the first component and the second component;
- and
- a seal assembly disposed between the first seal slot, the second seal slot, and the gap, wherein the seal assembly comprises a first intersegment seal, a second intersegment seal, and a rope seal, the rope seal is disposed in the first corner and the second corner, and the first intersegment seal, the second intersegment seal, and the rope seal in combination with one another are configured to substantially block a fluid from flowing through the gap and through one or both of the first corner and the second corner, wherein the first seal slot comprises a first segment and a second segment coupled to one another by the first corner, and the second seal slot comprises a third segment and a fourth segment coupled to one another by the second corner, wherein the first intersegment seal is configured to be disposed in the first segment of the first seal slot and the third segment of the second seal slot and the second intersegment seal is configured to be disposed in the second segment of the first seal slot and the fourth segment of the second seal slot, wherein the rope seal is configured to bias the first intersegment seal toward a first end of the first segment and a second end of the third segment and to bias the second intersegment seal toward a third end of the second segment and a fourth end of the fourth segment.
