    Abstract: A clearance control ring (48) having at least two segments (58) is disclosed. Each of the segments (58) interlock with adjacent segments (58) to form a full hoop clearance control ring (48). Separate carriers (54) and seals (50) or one- piece carriers (54) and seals (50) may be mounted on the clearance control ring (48). The segmented structure of the clearance control ring (48) allows for simpler assembly with segmented cases (52) for gas turbine engines (20) than prior art one- piece clearance control rings. The segmented structure also may be used with one- piece pre-assembled and multi-stage rotors (56).

    Abstract translation: 公开了具有至少两个段（58）的间隙控制环（48）。 每个段（58）与相邻段（58）互锁以形成完整的环空间隙控制环（48）。 分离的载体（54）和密封件（50）或一体式载体（54）和密封件（50）可以安装在间隙控制环（48）上。 间隙控制环（48）的分段结构允许与现有技术的单件间隙控制环相比，用于燃气涡轮发动机（20）的分段壳体（52）更简单地组装。 分段结构还可以与单件预组装和多级转子（56）一起使用。

    Abstract: A blade outer air seal system for a gas turbine engine includes a plurality of ring carriers made of a first material having a first coefficient of thermal expansion. A plurality of seal segments are carried, respectively, on the plurality of ring carriers. A ring member is carried in the plurality of ring carriers. The ring member is made of a second material that is different from the first material in composition. The second material has a second coefficient of thermal expansion such that the first coefficient of thermal expansion is 75 -175% of the second coefficient of thermal expansion.

    Abstract: A turbine engine system includes a turbine engine shaft, a first rotor, a second rotor and an engine monitoring system. The shaft includes a shaft bore formed by a shaft wall. The shaft bore extends along an axial centerline through the shaft between a first shaft end and a second shaft end. The first rotor is connected to the shaft at the first shaft end, and the second rotor is connected to the shaft at the second shaft end. The engine monitoring system includes a sensor connected to the second rotor, a transmitter arranged at the first shaft end, and a plurality of conduit assemblies. Each of the conduit assemblies includes a conduit that extends axially within the shaft bore and is connected to the shaft wall. A first one of the conduit assemblies also includes a wire that extends through a respective conduit and connects the sensor and the transmitter.
