    Abstract: A seal includes a seal runner, at least one seal ring, and a seal housing. The runner extends in an axial direction to a runner end face that faces a bearing. The ring is fixed to a static structure and has an inner surface engaging the seal runner and a first face that faces the bearing. The seal housing is fixed to the static structure and includes a first portion extending in an axial direction from the first face of the seal ring to a housing face that faces the bearing. The first portion has a first length extending from the first face of the seal ring to the housing face. The seal runner has a first runner portion with a second length that extends from the first face of the seal ring to the runner end face. The second length is at least 35% longer than the first length.

    Abstract: A seal assembly for a turbine engine is disclosed and includes a fixed housing including an axial surface defining an inner diameter and an annular seal that is disposed within the housing and seal against a radial surface of the fixed housing. The annular seal includes a first surface transverse to an axis of rotation and a second surface parallel to the axis of rotation defining an inner periphery. The first surface includes a first notch spaced apart from the inner periphery and overlapping the inner diameter of the fixed housing.

    Abstract: A ring seal assembly includes a first seal seat, a second seal seat axially abutting the first seal seat and two or more seal rings located axially between the first seal seat and the second seal seat. One or more pilot features are positioned at one or more of the first seal seat or the second seal seat to radially locate a ring seal of the two or more seal rings during assembly of the ring seal assembly. A method of installing a ring seal assembly includes securing a first seal seat at a rotating component, inserting a first seal ring onto the first seal seat, and installing a second seal ring and a second seal seat to the rotating component. The second seal ring is guided into a selected radial position via one or more pilot features located at the first seal seat and/or the second seal seat.

    Abstract: One embodiment of the seal housing for a face seal described herein include a base with a seal element support and a shroud both extending from the base in a common direction. The seal element support and the base define a space for receiving a seal element. The shroud includes a tip having a head portion that tapers toward a neck portion that is reduced in size relative to the head portion. The tip is secured to a stem of the shroud through a set of circumferentially distributed countersunk holes.
