Abstract

An electrical cable shroud forming an annular structure having an outer surface and an inner surface, the cable shroud comprising a substantially J-shaped cross-section having a longest side, a shorter leg, and a rounded portion therebetween. The longest side of the J forms the outer surface and the shorter leg forms the inner surface. The shorter leg turns inwardly and terminates in a tab extension substantially perpendicular to the outer surface, and the rounded portion forms an internal space suitable for enclosing electrical components.

Claims

1. An electrical cable shroud, said cable shroud forming an annular structure having an outer surface and an inner surface, said cable shroud comprising:

a substantially J-shaped cross-section having a longest side, a shorter leg, and a rounded portion therebetween, said longest side of the J forming said outer surface and said shorter leg forming said inner surface;

wherein said shorter leg turns inwardly and terminates in a tab extension substantially perpendicular to said outer surface, and said rounded portion forms an internal space suitable for enclosing electrical components.

2. A cable shroud in accordance with claim 1, wherein said cable shroud is unitarily formed.

3. A cable shroud in accordance with claim 1, wherein said cable shroud is formed in two or more segments.

4. A cable shroud in accordance with claim 1, wherein said inner surface is suitable for engaging an annular groove.

5. A cable shroud in accordance with claim 1, wherein said outer surface includes a plurality of apertures therethrough.

6. A cable shroud in accordance with claim 1, wherein said cable shroud is formed from composite materials.

7. A cable shroud in accordance with claim 6, wherein said cable shroud includes a metal mesh.

8. A gas turbine engine, said gas turbine engine including a core gas turbine engine, a fan assembly disposed upstream from said core gas turbine engine and enclosed by a fan frame assembly having an annular outer casing and an annular groove on an outer surface of said outer casing, said fan frame assembly comprising:

an electrical cable shroud, said cable shroud forming an annular structure having an outer surface and an inner surface, said cable shroud having a substantially J-shaped cross-section having a longest side, a shorter leg, and a rounded portion therebetween, said longest side of the J forming said outer surface and said shorter leg forming said inner surface and said rounded portion forming an internal space suitable for enclosing electrical components;

wherein said shorter leg turns inwardly and terminates in a tab extension substantially perpendicular to said outer surface, and wherein said tab extension is positioned in said annular groove and said outer surface of said cable shroud is secured to said outer surface of said outer casing.

9. A gas turbine engine in accordance with claim 8, further including at least one integrated cable support located in said internal space between said outer casing and said cable shroud.

10. A gas turbine engine in accordance with claim 8, wherein said cable support provides a damping force on said cable shroud.

11. A gas turbine engine in accordance with claim 8, wherein said cable shroud provides a compressive force on said cable support.

12. An electrical cable shroud, said cable shroud forming an annular structure having an outer surface and an inner surface which is formed from composite materials, said cable shroud comprising:

a substantially J-shaped cross-section having a longest side, a shorter leg, and a rounded portion therebetween, said longest side of the J forming said outer surface and including a plurality of apertures therethrough and said shorter leg forming said inner surface suitable for engaging an annular groove;

wherein said shorter leg turns inwardly and terminates in a tab extension substantially perpendicular to said outer surface, and said rounded portion forms an internal space suitable for enclosing electrical components.
