Abstract

A gas turbine engine (20) includes a compressor section (28), a combustion section (30), and a turbine section (32). The turbine section has a rotor stage (40) disposed adjacent an annular stator vane stage (42). The annular stator vane stage includes annular inner (50) and outer radial shrouds (52), stator vanes (48), and a retaining ring (72). The stator vanes are circumferentially spaced apart from one another, extending between the shrouds. The inner radial shroud is mechanically engaged with a first engine support structure (54) at a first position axially forward of the plurality of stator vanes, and the outer radial shroud is mechanically engaged with a second engine support (64) structure at a second position axially forward of the plurality of stator vanes. The annular stator vane stage includes a flange (66) extending outward from the outer radial shroud that is contiguous with the retaining ring.
