Abstract
Interference fits between CMC components and ancillary metal hardware within an engine casing can lead to damage to the CMC component and features thereof during assembly and/or over duration of many operating cycles. A method and arrangement are provided to prevent or ameliorate harmful effects resulting from interactions between CMC components and ancillary metal hardware by using spring elements. The spring elements are held in compression between an end wall of a bore hole in ancillary metal hardware and a structural feature, such as a flange, of the CMC component to urge the CMC component into a sealing and supporting engagement with a surface of ancillary metal hardware.
