Abstract: A gas turbine engine includes a containment ring to contain liberated compressor and turbine blades and blade fragments within a core assembly. The combination of a containment gap between the core case and the containment ring and a containment layer disposed in the gap helps dissipate the energy generated by loose body impacts on the core assembly. The containment layer deforms, deflects, and/or redirects the impact energy acting in a radial direction, thereby to improve containment.
Abstract translation: 燃气涡轮发动机包括容纳环，以容纳释放的压缩机和涡轮叶片以及芯组件内的叶片碎片。 芯壳与容纳环之间的容纳间隙和设置在间隙中的容纳层的组合有助于消散由芯体组件上的松动的身体撞击产生的能量。 容纳层使沿径向作用的冲击能量变形，偏转和/或重定向，从而改善容纳。

Abstract: A rotating blade tip clearance system includes a control ring carrier defining a centerline axis. The control ring carrier has a connecting portion, a retaining portion radially inward of the connecting portion, and a flange connecting radially between the connecting portion and the retaining portion. The flange isolates the retaining portion of the control ring carrier from the thermal deflection of a case and assists in keeping the control ring carrier aligned about centerline axis A during thermal deflection. The retaining portion includes radially inner and outer diameter sides defining a retaining cavity therebetween. The system includes a control ring within the retaining cavity. The control ring has a different thermal response rate from the control ring carrier so that the control ring thermally deflects slower than the control ring carrier, thereby controlling the rate and/or extent of thermal deflection of the control ring carrier.
Abstract translation: 旋转叶片顶端间隙系统包括限定中心线轴线的控制环载架。 控制环载体具有连接部分，连接部分径向向内的保持部分和连接部分与保持部分之间径向连接的凸缘。 法兰将控制环承载件的保持部分与壳体的热偏转隔离开来，有助于在热偏转期间保持控制环承载件在中心线轴线A上对齐。 保持部分包括在其间限定保持腔的径向内径和外径侧。 该系统包括保持腔内的控制环。 控制环具有与控制环载体不同的热响应速率，使得控制环比控制环载体更慢地偏转，从而控制控制环载体的热偏转的速率和/或程度。
