Retention clip for a blade outer air seal

1. A retention clip for supporting a blade outer air seal (BOAS) segment, comprising:

a main body portion;

a first projection extending from the main body portion and configured to be received in a slot of the blade outer air seal (BOAS) segment, wherein the slot extends in a circumferential direction and faces one of a fore direction and an aft direction relative to an engine central longitudinal axis; and

a second projection extending from the main body portion and configured to abut an end of the blade outer air seal (BOAS) segment, wherein the second projection extends further from the main body portion than the first projection,

wherein the main body portion, the first projection, and the second projection are integrally formed as a one-piece structure.

2. The retention clip as recited in claim 1 , wherein the first projection includes an arcuate face.

3. The retention clip as recited in claim 1 , wherein an inner surface of the main body portion includes a groove formed therein, the groove running along a length of the retention clip.

4. The retention clip as recited in claim 1 , wherein an outer surface of the main body portion includes a notch formed therein, the notch generally transverse to a length of the retention clip.

5. The retention clip as recited in claim 1 , wherein a flange extends from an outer surface of the main body portion.

6. The retention clip as recited in claim 1 , wherein a circumferentially-facing surface of the second projection is configured to abut a circumferential end of the blade outer air seal (BOAS) segment, and wherein the entire circumferential end of the blade outer air seal (BOAS) segment is defined by a planar surface extending in axial and radial directions.

7. A system, comprising:

a static segment having a circumferentially extending slot facing in one of a fore direction and an aft direction relative to an engine central longitudinal axis;

a retention clip partially received in the slot and partially contacting a circumferential end of the static segment; and

a support structure, wherein the retention clip includes a main body portion in contact with the support structure,

wherein a groove is formed in a radially inner-most surface of the main body portion, and wherein the support structure includes an arm received in the groove,

wherein the retention clip includes a first projection extending from the main body portion, the first projection received in the slot, and

wherein the retention clip includes a second projection extending further from the main body portion than the first projection, the second projection abutting the circumferential end of the static segment.

8. The system as recited in claim 7 , wherein one of the groove and the arm includes a convex surface.

9. The system as recited in claim 7 , wherein the support structure includes a flange, and wherein a face of the main body portion abuts the flange.

10. The system as recited in claim 7 , wherein the main body portion includes a notch formed in a radially outer surface thereof, and wherein the support structure includes a tab received in the notch.

11. The system as recited in claim 7 , wherein the support structure provides a channel, and wherein the main body portion is sized to correspond to a size of the channel.

12. The system as recited in claim 7 , wherein the retention clip is made of a material selected from the group consisting of (1) a ceramic material, (2) a nickel-based alloy, and (3) a cobalt-based alloy.

13. The system as recited in claim 7 , wherein the static segment includes a fore slot and an aft slot, each of the fore slot and the aft slot extending in a circumferential direction.

14. The system as recited in claim 7 , wherein the static segment is a blade outer air seal (BOAS) segment.
