Abstract: A control ring extends circumferentially about a central axis. A plurality of circumferentially spaced carrier portions have a cavity receiving the control ring. There are circumferential gaps between the carrier portions. A blade outer air seal is mounted on the carrier portions radially inwardly of the control ring. The control ring maintains the carrier portions at a radially outwardly expanded position when heated by an electric heater.

Abstract translation: 控制环围绕中心轴线周向延伸。 多个周向间隔的载体部分具有容纳控制环的空腔。 载体部分之间有圆周间隙。 叶片外部空气密封件安装在控制环径向向内的托架部分上。 当通过电加热器加热时，控制环将承载部分保持在径向向外扩展的位置。
