Abstract: A blade outer air seal assembly includes a blade outer air seal that has a plurality of segments that extend circumferentially about an axis and are mounted in a carrier. At least two of the plurality of segments have a first wall and a second wall circumferentially spaced from one another and a base portion that extends from the first wall to the second wall. The base portion extends circumferentially outward past the first and second walls to form first and second sealing surfaces. An intersegment seal has a curved surface. The curved surface is engaged with the first and second sealing surfaces between the at least two segments.

Abstract: A turbine section for a gas turbine engine includes a turbine blade that extends radially outwardly to a radially outer tip and for rotation about an axis of rotation. A support structure is arranged circumferentially about the axis of rotation and has a plurality of attachment members that extend radially inwardly. A blade outer air seal has a plurality of segments mounted in the support structure. Each segment has a first wall circumferentially spaced from a second wall. The first and second walls are joined to a base portion and an outer wall to define a passage that extends axially along the segment.

Abstract: A blade outer air seal assembly includes a support structure arranged about an axis. At least one blade outer air seal segment is mounted in the support structure. A flow guide is arranged between the support structure and the at least one blade outer air seal segment defining a passage between the flow guide and the blade outer air seal segment. The passage extends in a generally axial direction.

Abstract: A blade outer air seal assembly includes a blade outer air seal that has a plurality of seal segments that extend circumferentially about an axis and mounted in a support structure via a carrier. Each of the seal segments has a base portion that extends between a first circumferential side and a second circumferential side and from a first axial side to a second axial side. A first and second hook extend along the base portion in an axial direction. The first and second hooks are engaged with the carrier. The carrier has a wall forward or aft of the first and second hooks and extends radially inward of the first and second hooks.

Abstract: A blade outer air seal assembly includes a seal segment that has a base portion that extends between a first circumferential side and a second circumferential side and from a first axial side to a second axial side. A first wall is axially spaced from a second wall. The first and second walls extend from the base portion to an outer wall to define a circumferentially extending seal passage. A carrier has a platform. A portion of the platform is within the seal passage. A radially extending first hook protrudes from the platform and is configured to engage with a support structure.
