Case assembly for supporting stator vanes

摘要

A case assembly for supporting stator vanes of a gas turbine engine is disclosed. Various construction details and techniques which enable support of the vanes across the flow path of the engine are discussed. The construction details and techniques which provide damping to the vanes and accommodate differential thermal expansion between the vanes and the case assembly are developed. The vane mounting system disclosed is built around the concept of enabling sliding friction between components of the case assembly to dampen vane vibrations.
