Abstract

An assembly is provided for a gas turbine engine. This assembly includes a combustor and a fuel conduit. The combustor includes a combustor wall that forms a peripheral boundary of a combustion chamber within the combustor. The fuel conduit extends along and is formed integral with the combustor wall. The fuel conduit is disposed outside of the combustion chamber.

Claims (45)

1. An assembly for a gas turbine engine, comprising:

a combustor comprising a combustor wall that forms a peripheral boundary of a combustion chamber within the combustor;

a fuel conduit extending along and formed integral with the combustor wall, the fuel conduit disposed outside of the combustion chamber;

a turbine engine case with a plenum formed by and disposed between the turbine engine case and the combustor wall; and

a fuel manifold extending along and formed integral with the turbine engine case, the fuel manifold fluidly coupled with the fuel conduit.

2. The assembly of claim 1 , further comprising:

a fuel injector arranged with the combustor;

the fuel injector configured to receive fuel from the fuel conduit and inject the fuel into the combustion chamber.

3. The assembly of claim 2 , wherein the fuel injector is formed integral with the combustor and the fuel conduit.

4. The assembly of claim 1 , further comprising:

a second fuel conduit extending along and formed integral with the combustor wall;

the second fuel conduit disposed outside of the combustion chamber; and

the fuel manifold fluidly coupled with the second fuel conduit.

5. The assembly of claim 1 , wherein a segment of the fuel conduit projects out from the combustor, through the plenum, to the turbine engine case.

6. The assembly of claim 1 , wherein

the combustor includes an inner sidewall, an outer sidewall and a bulkhead extending radially between and connected to the inner sidewall and the outer sidewall; and

the bulkhead comprises the combustor wall.

7. The assembly of claim 6 , wherein the fuel conduit further extends along and is formed integral with the outer sidewall.

8. The assembly of claim 1 , further comprising:

a fuel injector arranged with the combustor and fluidly coupled with the fuel conduit; and

a segment of the fuel conduit laterally offset from the fuel injector.

9. The assembly of claim 1 , further comprising:

a fuel injector arranged with the combustor and fluidly coupled with the fuel conduit; and

a segment of the fuel conduit laterally aligned with the fuel injector.

10. The assembly of claim 1 , wherein at least a segment of the fuel conduit follows a straight trajectory as the fuel conduit extends along the combustor wall.

11. The assembly of claim 1 , wherein at least a segment of the fuel conduit follows a non-straight trajectory as the fuel conduit extends along the combustor wall.

12. The assembly of claim 1 , wherein a segment of the fuel conduit extends along and is spaced from the combustor wall.

13. The assembly of claim 1 , further comprising:

a nozzle; and

the combustor meeting the nozzle at a slip joint between the combustor and the nozzle.

14. An assembly for a gas turbine engine, comprising:

a combustor comprising a combustor wall that forms a peripheral boundary of a combustion chamber within the combustor; and

a fuel conduit extending along and formed integral with the combustor wall, the fuel conduit disposed outside of the combustion chamber;

wherein the combustor includes an inner sidewall, an outer sidewall and a bulkhead extending radially between and connected to the inner sidewall and the outer sidewall; and

wherein the outer sidewall comprises the combustor wall.

15. An assembly for a gas turbine engine, comprising:

a combustor comprising a combustor wall that forms a peripheral boundary of a combustion chamber within the combustor;

a fuel conduit extending along and formed integral with the combustor wall, the fuel conduit disposed outside of the combustion chamber; and

a fuel injector arranged with the combustor and fluidly coupled with the fuel conduit;

a segment of the fuel conduit laterally offset from the fuel injector, and the segment of the fuel conduit is circumferentially clocked from the fuel injector about a centerline of the gas turbine engine between five degrees and twenty-five degrees.

16. An assembly for a gas turbine engine, comprising:

a combustor including an outer sidewall, an inner sidewall, a bulkhead and a combustion chamber, the combustion chamber extending radially within the combustor between the outer sidewall and the inner sidewall, and the combustion chamber extending axially within the combustor to the bulkhead; and

a fuel conduit extending along and connected to the bulkhead, at least the fuel conduit and the bulkhead formed together in a monolithic body.

17. The assembly of claim 16 , wherein the fuel conduit also extend along and is connected to the outer sidewall.

18. The assembly of claim 16 , wherein the fuel conduit is disposed outside of the combustor.
