Structural cooling fluid tube for supporting a turbine component and supplying cooling fluid

摘要

A shaft cover support for a gas turbine engine is disclosed. The shaft cover support not only provides enhanced support to a shaft cover of the gas turbine engine, but also includes a cooling fluid chamber for passing fluids from a rotor air cooling supply conduit to an inner ring cooling manifold. As such, the shaft cover support accomplishes in a single component what was only partially accomplished in two components in conventional configurations. The shaft cover support may also provide additional stiffness and reduce interference of the flow from the compressor. In addition, the shaft cover support accommodates a transition section extending between compressor and turbine sections of the engine. The shaft cover support has a radially extending region that is offset from the inlet and outlet that enables the shaft cover support to surround the transition, thereby reducing the overall length of this section of the engine.

主权项

1. A shaft cover support for a gas turbine engine, comprising:
a cooling fluid chamber having at least one hollow cavity contained within the cooling fluid chamber; a radially outward inlet at a first end of the cooling fluid chamber; a radially inward outlet at a second end of the cooling fluid chamber; a radially outward axial mounting device coupled to an outer wall forming the cooling fluid chamber near the radially outward inlet; a radially inward axial mounting device coupled to the outer wall forming the cooling fluid chamber near the radially inward outlet; wherein the radially inward outlet and radially outward inlet are generally aligned with each other, and a radially extending region of the cooling fluid chamber is offset axially relative to the radially inward outlet and radially outward inlet to accommodate a transition of the turbine engine.
