Halo seal separate scallop support

1. A seal arrangement comprising:

a seal comprising an outer ring, a shoe, and an arm extending between the shoe and the outer ring, wherein the shoe moves relative to the outer ring via the arm;

a seal ring adjacent the seal; and

a support plate coupled to the shoe and disposed between the seal and the seal ring, wherein the support plate is configured to move together with the shoe in a radial direction relative to the seal ring.

2. The seal arrangement of claim 1 , wherein the seal, the seal ring, and the support plate are coaxial.

3. The seal arrangement of claim 2 , wherein the outer ring is in contact with the seal ring, the arm is spaced apart from the seal ring, and the shoe is spaced apart from the seal ring.

4. The seal arrangement of claim 3 , further comprising a fastener coupled between the shoe and the support plate, the fastener configured to prevent the support plate from moving relative to the shoe.

5. The seal arrangement of claim 3 , further comprising a pin coupled between the shoe and the support plate, the pin configured to prevent the support plate from moving relative to the shoe.

6. The seal arrangement of claim 3 , wherein the shoe is coupled to the support plate via at least one of a weld, a solder, or a braze.

7. The seal arrangement of claim 2 , wherein the seal comprises an annular geometry, the seal ring comprises an annular geometry, and the support plate comprises an annular geometry.

8. The seal arrangement of claim 1 , further comprising a carrier ring, wherein the seal, the seal ring, and the support plate are disposed within the carrier ring.

9. The seal arrangement of claim 8 , further comprising:

a spacer;

at least one secondary seal; and

a secondary seal cover, wherein at least a portion of the at least one secondary seal is located axially between the spacer and the secondary seal cover; and

the spacer, the at least one secondary seal, and the secondary seal cover are located opposite the seal from the seal ring.

10. The seal arrangement of claim 1 , wherein the support plate comprises a coefficient of friction which is less than that of the seal.

11. The seal arrangement of claim 1 , wherein the seal comprises a non-contact seal.

12. A method for assembling a seal arrangement comprising:

attaching a support plate to a shoe of a seal, the seal comprises an outer ring, the shoe, and an arm extending between the shoe and the outer ring, wherein the shoe and the support plate move together radially relative to the outer ring via the arm; and

placing the seal and the attached support plate into a carrier ring, a distal surface of the outer ring in contact with the carrier ring in response to the seal being placed into the carrier ring.

13. The method of claim 12 , further comprising placing a seal ring into the carrier ring.

14. The method of claim 13 , wherein the seal ring is placed axially adjacent to the seal.

15. The method of claim 14 , further comprising placing the outer ring and the support plate in contact with the seal ring.

16. The method of claim 15 , wherein the support plate slides against the seal ring in response to the shoe moving relative to the outer ring.

17. A seal arrangement comprising:

a seal comprising an outer ring, a shoe, and an arm extending between the shoe and the outer ring, wherein the shoe moves relative to the outer ring via the arm;

a seal ring adjacent the seal; and

a support plate coupled to the shoe and disposed between the seal and the seal ring, wherein the support plate moves radially with the shoe relative to the seal ring.

18. The seal arrangement of claim 17 , wherein a surface of the support plate is flush with the outer ring.

19. The seal arrangement of claim 18 , wherein the surface of the support plate is in contact with the seal ring.

20. The seal arrangement of claim 19 , wherein the support plate extends radially outwards from the shoe.
