Abstract: An airseal for sealing between a rotating component and a stationary component of a turbine engine includes a sealing surface defining a spacing between the airseal and a rotating component of the turbine engine and a mounting flange to secure the airseal to a stationary component of the turbine engine. An airseal body extends between the sealing surface and the mounting flange. The airseal body includes a cavity configured to absorb thermal energy transferred into the airseal from a flowpath of the turbine engine. A gas turbine engine includes a rotating component and a stationary component located radially outboard of the rotating component. An airseal is located therebetween and includes a sealing surface and a mounting flange to secure the airseal to the stationary component. An airseal body extends between the sealing surface and the mounting flange and includes a cavity to absorb thermal energy transferred into the airseal.

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: A seal structure may comprise a cavity defined at least partially by an axial surface and a radial surface. A brush seal may be disposed in the cavity. The brush seal may comprise a bristle pack and a backing plate coupled to the bristle pack. A first surface of the backing plate may contact the axial surface, and a second surface of the backing plate may contact the radial surface.

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: An interface arrangement includes two annular components that extend along an axis and are in contact with one another and a third component that is positioned radially inward from at least one of the two components. There is an anti-rotation feature on one of the three components that engages an anti-rotation feature on an annular seal member. The seal member is in contact with the first two components and is positioned between the third component and at least one of the first two components.

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.
