Impeller tube assembly

A turbomachine component, comprising:

• a wheel rotatable about a rotor axis and having a body and opposite wheel faces thereof;
• a plurality of tubes oriented in a radial dimension relative to the rotor axis and arranged in an annular array about the rotor axis;
• and
• an attenuation bracket coupled to one of the faces of the wheel to radially support the plurality of the tubes in rotational and non-rotational modes, the attenuation bracket comprising:
• an annular body having an annular attenuation arm defining first through-holes and an annular base defining second through-holes,
• the attenuation arm being connectable with the base such that each of the first through-holes is defined in positional alignment with a corresponding one of the second through-holes, and
• each of the plurality of the tubes being extendable through one of the first through-holes and the corresponding one of the second through-holes.

• and
• an attenuation bracket coupled to an inner diameter of one of the wheel faces of the wheel to radially support the plurality of the tubes in rotational and non-rotational modes, the attenuation bracket comprising:
• an annular body having an annular attenuation arm defining first cylindrical through-holes and an annular base defining second frusto-conical through-holes,
• the attenuation arm being connectable with the base such that each of the first through-holes is defined in positional alignment with a corresponding one of the second through-holes, and
• each of the plurality of the tubes being mechanically bonded to the attenuation arm and radially, outwardly extendable through one of the first through-holes and the corresponding one of the second through-holes.
