Abstract

A shrouded conduit is provided for arranging, for example, in a gas path of a turbine engine. The shrouded conduit includes a tubular shroud extending longitudinally along a centerline. The shrouded conduit also includes a fluid conduit extending longitudinally in the shroud. A first portion of the fluid conduit is connected laterally to and may be formed integral with a first portion of the shroud.

First claim

What is claimed is:

1. An assembly, comprising:
a fluid source;
a fuel injector nozzle;
a fluid conduit fluidly coupled with the fluid source and the fuel injector nozzle, and configured to provide liquid received from the fluid source to the fuel injector nozzle; and
a shroud circumscribing and shielding the fluid conduit;
wherein, when viewed in a plane perpendicular to a centerline of the fluid conduit, a first portion of the shroud is connected laterally to a first portion of the fluid conduit by a first spar at a first connection, and wherein the first spar is circumferentially adjacent and between a first hollow portion of the shroud and a second hollow portion of the shroud;
wherein, when viewed in the plane perpendicular to the centerline, a second portion of the shroud is connected laterally to a second portion of the fluid conduit by a second spar at a second connection, and wherein the second spar is circumferentially adjacent and between a third hollow portion of the shroud and a fourth hollow portion of the shroud;
wherein, when viewed in the plane perpendicular to the centerline, a third portion of the shroud is connected laterally to a third portion of the fluid conduit by a third spar at a third connection, and wherein the third spar is circumferentially adjacent and between a fifth hollow portion of the shroud and the fourth hollow portion of the shroud;
wherein, when viewed in the plane perpendicular to the centerline, a fourth portion of the shroud is directly connected laterally to and contiguous with a fourth portion of the fluid conduit at a fourth connection, and wherein the fourth connection is circumferentially adjacent and between the fifth hollow portion of the shroud and the first hollow portion of the shroud;
wherein, when viewed in the plane perpendicular to the centerline, a fifth portion of the shroud is directly connected laterally to and contiguous with a fifth portion of the fluid conduit at a fifth connection, and wherein the fifth connection is circumferentially adjacent and between the second hollow portion of the shroud and the third hollow portion of the shroud; and
wherein the first spar comprises a surface that extends uninterrupted from an outer surface of the fluid conduit to an inner surface of the shroud when viewed in the plane perpendicular to the centerline.

2. The assembly of claim 1 , wherein
the shroud extends longitudinally along a centerline; and
the fluid conduit extends longitudinally in the shroud.

3. The assembly of claim 1 , further comprising:
a structure through which a fluid flowpath extends;
wherein the shroud is disposed within the fluid flowpath.

4. The assembly of claim 1 , wherein the fuel injector nozzle comprises a turbine engine fuel injector nozzle.

5. The assembly of claim 1 , wherein the first portion of the shroud is formed integral with the first portion of the fluid conduit and the first spar at the first connection.

6. The assembly of claim 1 , wherein
the second spar comprises a second surface that extends uninterrupted from the outer surface of the fluid conduit to the inner surface of the shroud when viewed in the plane perpendicular to the centerline; and
the third spar comprises a third surface that extends uninterrupted from the outer surface of the fluid conduit to the inner surface of the shroud when viewed in the plane perpendicular to the centerline.

7. An assembly, comprising:
a fluid source;
a fuel injector nozzle;
a fluid conduit fluidly coupled with the fluid source and the fuel injector nozzle, and configured to provide liquid received from the fluid source to the fuel injector nozzle; and
a shroud circumscribing and shielding the fluid conduit;
wherein, when viewed in a plane perpendicular to a centerline of the fluid conduit, a first portion of the shroud is indirectly connected laterally to a first portion of the fluid conduit by a first spar at a first connection, and wherein the first spar is circumferentially adjacent and between a first hollow portion of the shroud and a second hollow portion of the shroud;
wherein, when viewed in the plane perpendicular to the centerline, a second portion of the shroud is directly connected laterally to and contiguous with a second portion of the fluid conduit at a second connection, and wherein the second connection is circumferentially adjacent and between a third hollow portion of the shroud and the second hollow portion of the shroud;
wherein, when viewed in the plane perpendicular to the centerline, a third portion of the shroud is directly connected laterally to and contiguous with a third portion of the fluid conduit at a third connection, and wherein the third connection is circumferentially adjacent and between a fourth hollow portion of the shroud and the first hollow portion of the shroud; and
wherein the first spar comprises a surface that extends uninterrupted from an outer surface of the fluid conduit to an inner surface of the shroud when viewed in the plane perpendicular to the centerline.
