The rotor assembly has a plurality of rotor blades circumferentially distributed around a disk. Each rotor blade extends from the disk to a shrouded end, and each rotor blade has a shroud disposed at the shrouded end. The forward vane assembly is disposed forward of the rotor assembly. The forward vane assembly has a plurality of first vanes disposed in an annular configuration, with each first vane extending between a first vane inner radial platform to a first vane outer radial platform. The forward vane assembly includes an outer radial casing that includes a casing segment and an air diverter. The air diverter extends axially and is disposed radially outside of the shroud of each rotor blade of the plurality of rotor blades.
