| description | A gas turbine engine assembly includes a compressor (52) including a plurality of rotors (64), where at least one of the plurality of rotors (64) includes a radial inner sealing surface (68). A rotating shaft (50) drives rotation of the plurality of rotors (64), where the rotating shaft (50) includes an annular groove (72) proximate the radial inner sealing surface (68). A seal (74) is disposed within the annular groove (72), and the seal (74) comprises at least two annular sections (88A-F) forming a complete circumference. Each of the at least two annular sections (88A-F) are separate parts and include a radially-facing sealing surface (84) engaged to the radial inner sealing surface (68) of the rotor (64) and an annular slot (82) disposed radially inward of the radially-facing sealing surface (84). A retainer (80) is disposed within the annular slot (82) limiting radial expansion of the at least two annular sections (88A-F). |
