    Abstract: A seal (200) according to the present disclosure includes a plate, and a floating shoe (200B) supported with respect to the plate (208) in a first direction. The floating shoe (200B) has a sealing feature (200C) extending in a second direction perpendicular to the first direction. At least one bearing (209) is between the plate (208) and the floating shoe (200B). The bearing (209)is configured to facilitate movement of the floating shoe (200B) with respect to the plate (208) in the second direction.
    A gas turbine engine including the seal and a method of sealing a rotating component with respect to a stationary component are also disclosed.

    Abstract: A seal assembly (10) includes first and second rings (16A,16B). The first ring (16A) includes a first outer ring (18A), a first beam (28A) connected to the first outer ring (18A), and a first shoe (22A). The first shoe (22A) includes free and fixed ends (24A,26A) and is configured to move radially. The second seal ring (16B) is disposed axially adjacent and is attached to the first seal ring (16A). The second seal ring (16B) includes a second outer ring (18B), a second beam (28B) connected to the second outer ring (18B), and a second shoe (22B). The second shoe (22B) includes free and fixed ends (24B,26B) and is configured to move in a generally radial direction. The free end (24B) of the second shoe (22B) is disposed axially adjacent to the fixed end (26A) of the first shoe (22A). The fixed end (26B) of the second shoe (22B) is disposed axially adjacent to the free end (24A) of the first shoe (22A).

    Abstract: Aspects of the disclosure are directed to a non-contact seal assembly comprising a plurality of seal shoes (54) arranged about a centerline (22) in an annular array, the seal shoes (54) including a first seal shoe (54) extending axially along the centerline (22) between a first shoe end (70) and a second shoe end (72). The non-contact seal assembly may comprise a seal base (52) circumscribing the annular array of the seal shoes (54), the seal base (52) comprising first, second and third inner radial seal base surfaces (33, 35, 37) where the third inner radial seal base surface (37) is axially between the first and second inner radial seal base surfaces (33, 36) and is radially proximate the centerline (22) with respect to the radially distal first and second inner radial seal base surfaces (33, 35). The non-contact seal assembly may further comprise a plurality of spring elements (56), each of the spring elements (56) radially distal from and connecting to a respective one of the seal shoes (54) and radially proximate the third inner radial seal base surface (37).
