Abstract: A hydrostatic seal and rotor assembly includes a rotor having a rotor rotational direction about a rotor central axis, and a hydrostatic seal assembly including a seal support, a seal shoe configured for sealing between the seal shoe and the rotor, and one or more seal beams operably connecting the seal shoe to the seal support. The one or more seal beams are configured as spring elements integral with the seal shoe to allow radial movement of the seal shoe relative to the seal support. The seal shoe is circumferentially cantilevered from a fixed end to a free end opposite the fixed end. The fixed end is located circumferentially upstream of the free end relative to the rotor rotational direction.

Abstract: A component retaining assembly includes a housing including a circumferential slot. A component is mated to the housing. The component includes a first face including at least two tabs. The at least two tabs extending at outward from the first face at least partially past a portion of the circumferential slot. A retaining ring is disposed within the circumferential slot and abuts the first face of the component. The at least two tabs overlap a portion of the retaining ring. A gas turbine engine and a method are also disclosed.

Abstract: An anti-rotation assembly may include a first shaft, a second shaft, and a locking sprocket. The first shaft may have a first crenelated end rim, the second shaft may have a second crenelated end rim, and the locking sprocket may be configured to engage the first crenelated end rim and the second crenelated end rim to anti-rotatably couple the first shaft to the second shaft. That is, the locking sprocket may be configured to prevent relative rotation between the two shafts. The anti-rotation assembly may further include an axial retaining ring configured to axially retain the locking sprocket.

Abstract: A brush seal plate may comprise a flat ring with bristles protruding from an inner diameter of the flat ring. The brush seal plate may have a racetrack slot to allow the flat ring to move in a radial direction relative to a retention pin. The bristles may protrude from the inner diameter of the flat ring at an angle. A slot may be formed through the flat ring, and the slot may be angled. The flat ring may be circumferentially discontinuous. The flat ring may further comprise a retention opening configured to fix the flat ring in place relative to a retention pin.

Abstract: A seal sub-assembly may comprise a spacer, at least one secondary seal, and a secondary seal cover. At least a portion of the at least one secondary seal are located axially between the spacer and the secondary seal cover. The spacer is attached to the secondary seal cover. The spacer may comprise a first flange and a second flange. The at least one secondary seal may be located axially in line with and radially inward from the first flange. At least a portion of the secondary seal cover may be located axially in line with and radially inward from the second flange.

Abstract: A retaining ring for a turbomachine disk and coverplate assembly includes a ring body defining a coverplate interface side and an opposed disk lip interface side. A flow feature is defined by the ring body on the coverplate interface side to allow airflow between the turbomachine disk coverplate and the ring body such that a pocket defined between the coverplate and the turbomachine disk is in fluid communication with a conditioning flow pathway through the retaining ring.
