Abstract

A hanger for a turbine engine can include a first surface confronting a cooling airflow, a second surface facing a heated airflow, and a third surface radially outward of the first surface. The hanger can also include a cyclonic separator with a dirty air inlet and a clean air outlet, as well as a cooling air circuit extending through the cyclonic separator.

Claims (43)

1. A hanger for a turbine engine comprising:

a first surface confronting a cooling airflow;

a second surface facing a heated airflow;

a third surface radially outward of the second surface;

a diagonal load brace along the third surface;

a cyclonic separator with a cyclone body having a conical portion and a cylindrical portion and defining a centerline parallel to the diagonal load brace, the cyclone body at least partially defined by the third surface and having a dirty air inlet, a clean air outlet, and a scavenge outlet positioned radially outward of the clean air outlet; and

a cooling air circuit having a cooling air inlet on the first surface and a cooling air outlet on the second surface and extending through the cyclonic separator between the dirty air inlet and the clean air outlet.

2. The hanger of claim 1 wherein the dirty air inlet is positioned radially outward of the clean air outlet.

3. The hanger of claim 1 , further comprising multiple cyclonic separators and multiple cooling air circuits each extending through corresponding multiple cyclonic separators.

4. The hanger of claim 1 wherein both the conical and cylindrical portions are aligned with the centerline.

5. The hanger of claim 4 wherein the clean air outlet is aligned with the centerline.

6. The hanger of claim 1 wherein at least one of the dirty air inlet or the clean air outlet are located in the cylindrical portion.

7. The hanger of claim 6 wherein the scavenge outlet is located in the conical portion.

8. The hanger of claim 1 , further comprising an inlet conduit extending through the first surface and fluidly coupling the cooling air inlet to the dirty air inlet.

9. The hanger of claim 1 , further comprising an outlet conduit extending through the second surface and fluidly coupling the clean air outlet and the cooling air outlet.

10. The hanger of claim 1 , further comprising a monolithic body having the first surface, second surface, third surface, and cyclonic separator.

11. A shroud and hanger assembly for a turbine engine comprising:

a hanger, comprising:

a first surface confronting a cooling airflow;

a second surface facing a heated airflow;

a third surface radially outward of the first second surface;

a diagonal load brace along the third surface;

a cyclonic separator with a cyclone body having a conical portion and a cylindrical portion and defining a centerline parallel to the diagonal load brace, the cyclone body at least partially defined by the third surface and having a dirty air inlet, a clean air outlet, and a scavenge outlet positioned radially outward of the clean air outlet; and

a cooling air circuit having a cooling air inlet on the first surface and a cooling air outlet on the second surface and extending through the cyclonic separator between the dirty air inlet and the clean air outlet; and

a shroud, comprising:

an inner surface confronting the second surface of the hanger;

a heated surface facing the heated airflow; and

a shroud cooling circuit fluidly coupled to the cooling air circuit and extending through the shroud between a shroud inlet on the inner surface and a shroud outlet on the heated surface.

12. The shroud and hanger assembly of claim 11 wherein the dirty air inlet is positioned radially outward of the clean air outlet.

13. The shroud and hanger assembly of claim 12 wherein the cyclone body further comprises a conical portion and a cylindrical portion.

14. The shroud and hanger assembly of claim 13 wherein the shroud inlet is fluidly coupled to the clean air outlet at the cylindrical portion.

15. The shroud and hanger assembly of claim 13 wherein the scavenge outlet is located at the conical portion and fluidly separated from the shroud cooling circuit.

16. The shroud and hanger assembly of claim 12 further comprising a baffle positioned between the second surface of the hanger and the inner surface of the shroud and defining at least one of a pre-impingement cavity or a post-impingement cavity.

17. A turbine engine including a compressor, a combustor, and a turbine in axial flow arrangement, comprising:

a cooled component having an interior cooling passage and a heated surface facing a heated airflow; and

a hanger, comprising:

a first surface confronting a cooling airflow;

a second surface facing the heated airflow;

a third surface radially outward of the second surface;

a diagonal load brace along the third surface;

a cyclonic separator with a cyclone body having a conical portion and a cylindrical portion and defining a centerline parallel to the diagonal load brace, the cyclone body at least partially defined by the third surface and having a dirty air inlet, a clean air outlet, and a scavenge outlet positioned radially outward of the clean air outlet; and

a cooling air circuit fluidly coupled to the interior cooling passage, the cooling air circuit having a cooling air inlet on the first surface and a cooling air outlet on the second surface and extending through the cyclonic separator between the dirty air inlet and the clean air outlet.

18. The turbine engine of claim 17 wherein the cooled component comprises a portion of a casing surrounding at least one of the compressor, the combustor, or the turbine.
