Abstract
An assembly may include a rim-rotor turbine having a hub adapted to be mounted or connected to a rotating shaft, a rim-rotor, the rim-rotor having a cooling ring defining at least one cooling channel, and a plurality of blades with each of the plurality of blades contacting the rim-rotor. A stator vane assembly is positioned upstream of the rim-rotor turbine, and has an outer shroud defining a main flowpath aligned with the plurality of blades of the rim-rotor turbine and configured to direct hot gas toward the plurality of blades of the rim-rotor turbine, and vanes in the main flowpath. A cooling guide vane assembly has an inner shroud defining a cooling flowpath aligned with the cooling ring of the rim-rotor turbine and configured to direct cooling gas toward the cooling ring of the rim-rotor turbine, and vanes in the cooling flowpath. The outer shroud of the stator vane assembly is radially inward of the inner shroud of the cooling guide vane assembly, and wherein a circumference gap is defined therebetween.
