US Patent 10364707 Retention assembly for gas turbine engine components

Component retention assemblies and flowpath assemblies are provided. An exemplary retention assembly comprises a flange attached to a support structure, a retention ring received in a flange groove, and an attachment bracket comprising a component of a gas turbine engine. A first segment of the attachment bracket is axially disposed between the flange and a support structure first portion, and a second segment of the attachment bracket is radially disposed between the flange and a support structure second portion. The flange axially loads and the retention ring radially loads the attachment bracket into the support structure. An exemplary flowpath assembly comprises a retention assembly including a flange attached to a casing, a retention ring, and a CMC attachment bracket comprising a plurality of CMC components. The flange axially loads the attachment bracket into an axial stop, and the retention ring radially loads the attachment bracket into the casing.
