Abstract

Gas turbine engine systems involving I-beam struts are provided. In this regard, a representative strut assembly for a gas turbine engine includes a first I-beam strut having first and second flanges spaced from each other and interconnected by a web, the first strut exhibiting a twist along a length of the web.

First claim

What is claimed is:

1. A gas turbine engine comprising:
a compressor;
a combustion section operative to receive compressed air from the compressor;
a turbine operative to drive the compressor;
a casing operative to encase the compressor, the combustion section and the turbine;
a strut assembly interconnected with the casing and including an inner ring and an outer ring located about a centerline of the casing, and at least one strut interconnecting the inner ring and the outer ring;
wherein the at least one strut is configured as an I-beam-and includes a web extending between a first end and a second end, a first flange located along a leading edge of the web, and a second flange located along a trailing edge of the web; and
wherein the at least one strut is operable to prevent movement of the inner ring relative to the outer ring along the centerline, and vice versa.

2. The engine of claim 1 , wherein the at least one strut exhibits a twist along a length thereof.

3. The engine of claim 2 , wherein the at least one strut exhibits the twist such that the first end and the second end form an included angle of between approximately 1° and approximately 45°.

4. The engine of claim 3 , wherein the first end and the second end form an included angle of between approximately 5° and approximately 30°.

5. The engine of claim 1 , further comprising a fairing located along a gas path of the engine and positioned about the at least one strut.

6. The engine of claim 5 , wherein the engine further comprises an oil conduit operative to direct oil, and wherein at least a portion of the oil conduit is positioned between the at least one strut and the fairing.

7. The engine of claim 6 , wherein the at least one strut has a cutout formed therethrough, and wherein the oil conduit extends at least partially into the cutout.

8. The engine of claim 1 , wherein the at least one strut exhibits a camber.

9. The engine of claim 1 , wherein the at least one strut is one of multiple struts of the strut assembly, and wherein each of the multiple struts extends outwardly from the inner ring.

10. A gas turbine engine comprising:
a compressor;
a combustion section operative to receive compressed air from the compressor;
a turbine operative to drive the compressor;
a casing operative to encase the compressor, the combustion section and the turbine;
a strut assembly interconnected with the casing and including an inner ring and an outer ring located about a centerline of the casing, and at least one strut interconnecting the inner ring and the outer ring;
wherein the at least one strut is configured as an I-beam and includes a web extending between a first end and a second end, a first flange located along a leading edge of the web, and a second flange located along a trailing edge of the web; and
wherein the at least one strut is operable to prevent movement of the inner ring relative to the outer ring along an axis extending perpendicular to the centerline, and vice versa.

11. The engine of claim 10 , wherein the at least one strut exhibits a twist along a length thereof.

12. The engine of claim 11 , wherein the at least one strut exhibits the twist such that the first end and the second end form an included angle of between approximately 1° and approximately 45°.

13. The engine of claim 12 , wherein the first end and the second end form an included angle of between approximately 5° and approximately 30°.

14. The engine of claim 10 , further comprising a fairing located along a gas path of the engine and positioned about the at least one strut.

15. The engine of claim 14 , wherein the engine further comprises an oil conduit operative to direct oil, and wherein at least a portion of the oil conduit is positioned between the at least one strut and the fairing.

16. The engine of claim 15 , wherein the at least one strut has a cutout formed therethrough, and wherein the oil conduit extends at least partially into the cutout.

17. The engine of claim 10 , wherein the at least one strut exhibits a camber.
