    Abstract: Oil slinger systems include a seal runner comprising an annular radial member having a radius (R) and an outer axially extending member having an axial length (L) such that a ratio (L/R) is between 0.8 and 1.4, the annular radial member disposed at a first angle with respect to the outer axially extending member, a heat shield in mechanical communication with the seal runner, and a volume bounded by an outer face of the annular radial member and an inner face of the heat shield. Methods of radial convective cooling include pumping a cooling liquid through the oil slinger system and convectively cooling the oil slinger.

    Abstract: A blade outer air seal assembly includes a carrier that has a slot and a hole that extends into the slot. A blade outer air seal has a plurality of segments that extend circumferentially about an axis and mounted in the carrier. At least one of the plurality of segments has a base portion and a first wall that extends axially and radially outwardly from the base portion. The first wall has an aperture. A pin extends through the hole and the aperture.

    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 support structure. At least two of the segments have a first wall circumferentially spaced from a second wall. A base portion extends from the first wall to the second wall. A first hook extends from the first wall and a second hook extends from the second wall. A wedge seal is arranged between the at least two adjacent seal segments. A clip is configured to bias the wedge seal radially inward.

    Abstract: A gas turbine engine turbine section includes at least one blade extending radially outwardly to an outer tip. A blade outer air seal assembly is positioned radially outwardly of the radially outer tip. The blade outer air seal has forward and aft hooks. The forward and aft hooks are supported on forward and aft seal hooks of an attachment block. The attachment block has a forward case mount hook and an aft case mount hook. The attachment block is supported on a forward case hook and an aft case hook of a static casing within the engine. The forward case mount hook and the aft case mount hook on the attachment block face in a common axial direction. The forward case hook and the aft case hook face in a common axial direction which is opposed to the common axial direction. A method is also disclosed.
