Abstract
A gas turbine engine is provided that includes a compressor section, a combustion section, and a turbine section. The turbine section has a rotor stage disposed adjacent an annular stator vane stage. The annular stator vane stage includes an annular inner and outer radial shrouds, stator vanes, and a retaining ring. 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 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 structure at a second position axially forward of the plurality of stator vanes. The annular stator vane stage includes a flange extending outward from the outer radial shroud that is contiguous with the retaining ring.
