Abstract: A blade outer air seal support includes, at least one arc body having a first portion and a second portion, a blade outer air seal mounting region defined at least partially between the first portion and the second portion, and an interface feature interfacing the first portion and the second portion. The interface feature is configured such that axially aligned forces are communicated between the first and second portions through the interface feature, bypassing the blade outer air seal mounting region.

Abstract: A rotor assembly for a gas turbine engine includes a rotor disc having an axially extending rotor disc arm and a plurality of rotor blades extending radially outwardly from the rotor disc. A cover plate is located at an axial face of the rotor disc and at least partially retained at a rotor disc arm. The rotor disc and cover plate define a rotor cavity. A plurality of airflow openings extend into the cavity to allow a flow of air into the rotor cavity to thermally condition the rotor disc and the cover plate at the rotor cavity.

Abstract: A rotor disk is provided. The rotor disk may comprise a disk lug and a trench. The disk lug may be fixed to a distal surface of the rotor disk. The trench may be disposed on a surface of the disk lug. The trench may extend radially inwards from a distal surface of the disk lug. The trench may be configured to at least partially define a flow path by which cooling air may reach a distal surface of the disk lug in order to provide disk lug cooling.

Abstract translation: 提供转子盘。 转子盘可以包括盘凸耳和沟槽。 盘片可以固定在转子盘的远端表面上。 沟槽可以设置在盘形凸耳的表面上。 沟槽可以从盘片的远端表面径向向内延伸。 沟槽可以构造成至少部分地限定流动路径，通过该流动路径，冷却空气可以到达盘片的远侧表面，以便提供盘片冷却。

Abstract: A seal assembly includes a seal arc segment that defines radially inner and outer sides with the radially outer side including radially-extending sidewalls. A radially inner surface joins the radially-extending sidewalls. The radially-extending sidewalls and the radially inner surface define a pocket. A rail shield has radially-extending walls lines the radially-extending sidewalls.
