Abstract: Apparatus and associated methods relate to a segmented radial seal assembly that includes at least two segments, each segment having a first end and a second end at opposite ends. A first segment first end has a protruding feature and defines a tangential vector from a circumferential ring that is formed by the segmented radial seal. The protruding feature defines a curved face having at least a first axis of curvature that is parallel to the tangential vector. The second segment second end has a recessed feature that is matingly engageable to the first segment first end, thereby forming a first radial seal segment joint. The segmented radial seal assembly is configured to surround a shaft.

Abstract: A gas turbine engine includes a cover, a support, and a sealing member. The cover has a cover housing and a cover arm extending from the cover housing between a first arm end connected to the cover housing and a second arm end having a cover end surface. The support has a support body, a first support arm extending between a first support arm first end connected to the support body and a first support arm second end. The cover arm extends into the first support arm. The sealing member at least partially extends across a gap defined between the cover end surface and the first support arm.

Abstract: An assembly includes a housing, a carrier, a spring element and a seal element. The housing includes a bore and an annular groove that extends axially along a centerline into the housing from the bore. The carrier projects axially along the centerline into the annular groove. The carrier is configured to translate axially along the centerline relative to the housing. The spring element is arranged within the annular groove. The spring element is configured to bias the carrier axially away from the housing along the centerline. The seal element is mounted to the carrier and arranged within the bore.
