Abstract

A combustor section is provided for a gas turbine engine. The combustor section may include an outer liner panel, an inner liner panel and a bulkhead, which is arranged with the outer and the inner liner panels to form an annular combustion chamber. The combustor section may also include a swirler assembly and a combustor vane. The swirler assembly may be configured with the bulkhead. The combustor vane may extend at least partially into said combustion chamber, wherein the combustor vane is circumferentially aligned with the swirler assembly.

First claim

What is claimed is:

1. A combustor section for a gas turbine engine, the combustor section comprising:
an outer liner panel, an inner liner panel and a bulkhead arranged with the outer and the inner liner panels to form an annular combustion chamber with a longitudinal axis;
a swirler assembly configured with the bulkhead;
a combustor vane which extends at least partially into said combustion chamber, wherein the combustor vane extends between a leading edge and a trailing edge, and wherein the leading edge of the combustor vane is circumferentially aligned with a center of the swirler assembly about the longitudinal axis;
wherein said combustor vane includes a swirler located along the leading edge of the combustor vane; and
wherein said swirler includes an annular inner jet compartment.

2. The combustor section as recited in claim 1 , wherein said combustor vane is located between an outer liner panel and an inner liner panel.

3. The combustor section as recited in claim 1 , wherein said combustor vane defines a length between 35%-65% of said combustion chamber.

4. The combustor section as recited in claim 1 , wherein said swirler includes a multiple of supply air chambers.

5. The combustor section as recited in claim 4 , wherein said annular inner jet compartment includes a convergent-divergent section.

6. The combustor section as recited in claim 5 , wherein a divergent portion of said convergent-divergent section communicates with a dilution passage.

7. The combustor section as recited in claim 6 , wherein said dilution passage communicates with a dilution hole.

8. The combustor section as recited in claim 7 , wherein said dilution hole is located within a tailored depression.

9. The combustor section as recited in claim 8 , wherein each of said multiple of supply air chambers communicates with at least one cooling hole located radially between said convergent divergent section and said dilution hole.

10. The combustor section as recited in claim 1 , wherein said combustor vane is manufactured of a refractory metal core (RMC) material.

11. The combustor section as recited in claim 10 , wherein said combustor vane includes an RMC circuit along a main body of said combustor vane.

12. The combustor section as recited in claim 10 , wherein said combustor vane includes centerline RMC microcircuit with pedestals along a trailing edge of said combustor vane.

13. The combustor section as recited in claim 10 , wherein said combustor vane includes a multiple of swirlers stacked along a leading edge of said combustor vane.

14. A combustor section of a gas turbine engine, the combustor section comprising:
an outer liner panel, an inner liner panel and a bulkhead arranged with the outer and the inner liner panels to form an annular combustion chamber with a longitudinal axis;
a swirler assembly configured with the bulkhead, the swirler assembly extending axially along a centerline; and
a combustor vane having a swirler, the combustor vane extending between a leading edge and a trailing edge, and the leading edge of the combustor vane circumferentially aligned with the centerline of the swirler assembly about the longitudinal axis;
the swirler comprising:
an annular inner jet compartment which defines a convergent-divergent section; and
a multiple of supply air chambers in communication with said annular inner jet compartment.

15. The combustor section swirler as recited in claim 14 , wherein said convergent-divergent section is directed through a leading edge of a combustion vane.

16. The combustor section swirler as recited in claim 14 , wherein a divergent portion of said convergent-divergent section communicates with a dilution passage, said dilution passage in communication with a dilution hole radially outboard of said annular inner jet compartment, said dilution hole located within a tailored depression.

17. A combustor section for a gas turbine engine, the combustor section comprising:
an outer liner panel, an inner liner panel and a bulkhead arranged with the outer and the inner liner panels to form an annular combustion chamber, the combustion chamber extending axially along and circumferentially around an axis;
a swirler assembly configured with the bulkhead, the swirler assembly extending axially along a centerline; and
a combustor vane having at least one dilution hole, wherein the combustor vane extends between a leading edge and a trailing edge, and wherein the leading edge of the combustor vane is circumferentially aligned with the centerline of the swirler assembly about the axis;
wherein said combustor vane includes a swirler located along the leading edge of the combustor vane; and
wherein said swirler includes an annular inner jet compartment.
