Abstract

Gas turbine engine systems involving integrated fluid conduits are provided. In this regard, a representative engine casing for a gas turbine engine includes: a casing wall; and a fluid conduit integrated into the casing wall.

First claim

The invention claimed is:

1. A gas turbine engine comprising:
a casing having an exterior defined, at least in part, by a casing wall;
a fluid conduit integrated into the casing wall;
the fluid conduit comprises a conduit wall providing a fluid-routing channel;
wherein the fluid-routing channel has a first portion located radially outboard of the casing wall and a second portion located radially inboard of the casing wall.

2. The gas turbine engine of claim 1 comprising:
wherein said casing includes a fan casing wall and a high pressure casing wall; and
said fluid conduit integrated into a portion of the fan casing wall and a portion of the high pressure casing wall.

3. The engine of claim 2 , wherein the fluid conduit has interconnected multiple segments.

4. The engine of claim 3 , wherein a first of the multiple segments is located only on the fan casing wall and a second of the multiple segments is located only on the high pressure casing wall.

5. The engine of claim 4 , wherein:
the engine further comprises a fitting; and
a first of the multiple segments is interconnected with a second of the multiple segments using the fitting.

6. The engine of claim 3 , wherein at least two of the multiple segments are formed in a branch configuration such that the at least two of the multiple segments interconnect without the use of a fitting.

7. The engine of claim 1 , further comprising a fitting operative to interconnect the fluid conduit with another conduit for routing fluid to a component remote from the engine.

8. The engine of claim 1 , wherein the fluid conduit is operative to route air.

9. The engine of claim 1 , wherein the engine is a turbofan gas turbine engine.

10. An engine casing comprising:
an exterior defined, at least in part, by a casing wall;
a fluid conduit integrated into the casing wall;
the fluid conduit comprises a conduit wall providing a fluid-routing channel;
wherein the fluid-routing channel has a first portion located radially outboard of the casing wall and a second portion located radially inboard of the casing wall.

11. The engine casing of claim 10 , comprising:
wherein said casing includes a fan casing wall and a high pressure casing wall; and said fluid conduit integrated into a portion of the fan casing wall and a portion of the high pressure casing wall.

12. The engine casing of claim 10 , wherein the fluid conduit has interconnected multiple segments.

13. The engine casing of claim 12 , wherein a first of the multiple segments is located only on a fan casing and a second of the multiple segments is located only on a high pressure casing.

14. The engine casing of claim 12 , wherein:
the casing further comprises a fitting; and
a first of the multiple segments is interconnected with a second of the multiple segments using the fitting.

15. The engine casing of claim 12 , wherein at least two of the multiple segments are formed in a branch configuration such that the at least two of the multiple segments interconnect without the use of a fitting.

16. The engine casing of claim 10 , wherein the fluid conduit is operative to route air.

17. The engine casing of claim 10 , wherein the engine casing is used in a turbofan gas turbine engine.

18. The engine of claim 1 , wherein the conduit wall provides the entirety of the fluid-routing channel.

19. The engine of claim 1 , wherein the fluid-routing channel is substantially circular in cross section.

20. The engine casing of claim 10 , wherein the conduit wall provides the entirety of the fluid-routing channel.
