Abstract: A brush seal includes a bristle pack disposed between a top plate and a back plate. A sliding backing plate is disposed between the bristle pack and the back plate. The bristle pack includes a first bristle set that extends across a seal gap between a first engine component and a second engine component to prevent leakage across the seal gap and a second bristle set that exerts a force on the sliding backing plate. The sliding backing plate supports at least a portion of the first bristles and extends across the seal cavity to contact the second component. The force exerted on the sliding backing plate drives the sliding backing plate into contact with the second component.

Abstract: The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a first seal section including one or more first slots formed therein, a second seal section including one or more second slots formed therein and one or more frustoconical rings disposed in respective ones of the slots, such that the first and second seal sections and the frustoconical rings move relative to one another during relative movement between the two components. A wave spring disposed between the first and second seal sections biases the first and second seal sections away from one another.

Abstract: The present disclosure relates generally to a sliding seal between two components. The sliding seal includes a carrier having one or more cavities formed therein. The one or more carriers may contain wave springs and/or compliant seals therein. Various embodiments provide loading of the seal in both the axial and radial directions, regardless of whether a pressure differential exists across the seal, by means of springs and/or ramped surfaces. Other combinations of carrier, wave springs, and compliant seals are also disclosed.

Abstract: A multi-ply seal ring includes an inner seal ring and an outer seal ring. The inner seal ring includes a plurality of discrete inner ring segments disposed circumferentially about an axis in an annular array. The inner ring segments are arranged end-to-end within the annular array. The inner seal ring is engaged with and nested within the outer seal ring. In addition or alternatively, the outer seal ring may include a plurality of discrete outer ring segments disposed circumferentially about the axis in an annular array.

Abstract: A seal for a gas turbine engine may include a first cartridge, a second cartridge, and a wave spring. The wave spring may be located between the first cartridge and the second cartridge. The first cartridge may contact a first component to form a seal. The second cartridge may contact a second component to form a seal. The first cartridge may contact the second cartridge to form a seal. The wave spring may force the first cartridge to contact the first component, and the wave spring may force the second cartridge to contact the second component.

Abstract: A seal assembly includes a first component, a second component, a first seal, a first shelf, a second shelf, and a second seal. The second component is adjacent to the first component and forms a cavity between the first and second components. The first seal spans the cavity. The first shelf extends axially from the first component and is located between the first seal and a hot gas path. The second shelf extends axially from the second component and is located between the first shelf and the hot gas path; the second shelf together with the first shelf forms a flow channel. The second seal conforms to the first shelf, sealing the flow channel.
