Abstract
A shroud portion of a fluid-conduit housing provides for concentrically shrouding a portion of bladed rotor operatively coupled to a rotor shaft rotationally supported by at least one bearing operatively coupled to the centerbody. An internal cylindrical surface at an end of the fluid-conduit housing mates with a corresponding external cylindrical surface on a corresponding side of the centerbody. The fluid-conduit housing is operatively coupled to the centerbody with a plurality of radial pins, wherein each radial pin slideably engages with at least one of a corresponding radial bore in the fluid-conduit housing or a corresponding radial bore in the centerbody so as to provide for substantially maintaining the concentricity of the shroud portion of the fluid-conduit housing relative to the bladed rotor regardless of a thermal expansion of the fluid-conduit housing relative to the centerbody.
