Abstract: A structure providing compliance and sealing between ceramic or ceramic composite (CMC) part and a metallic part has an interface component for centering the CMC part in the metallic part, thus reducing thermal stress motion of the CMC component. In gas turbine engine applications, the structure comprises a CMC blade track inserted in a clip placed within a metallic hanger. The clip provides for radial compliance and secures controlled leakage of cooling air required to ensure that acceptable temperatures are maintained for the metallic structures. A washer is positioned adjacent to the clip provide for axial orientation of the blade track.

Abstract translation: 在陶瓷或陶瓷复合材料（CMC）部件和金属部件之间提供柔性和密封的结构具有用于使CMC部件在金属部件中居中的界面部件，由此减少CMC部件的热应力运动。 在燃气涡轮发动机应用中，该结构包括插入放置在金属吊架内的夹子中的CMC刀片轨道。 该夹子提供径向顺应性并确保所需冷却空气的受控泄漏，以确保金属结构的可接受温度得以维持。 垫圈与夹子相邻定位以提供叶片轨道的轴向定向。
