Turbine engine hanger
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.
1. A hanger for a turbine engine having an engine centerline, comprising:
a first surface confronting a cooling airflow;
a second surface facing a heated airflow;
a third surface radially outward of the second surface relative to the engine centerline;
a cyclonic separator, comprising:
a cyclone body at least partially defined by the third surface and having a conical portion, a cylindrical portion, and a separator centerline extending through the conical portion and the cylindrical portion, with the separator centerline unaligned with the engine centerline;
a dirty air inlet and a clean air outlet in the cylindrical portion; and
a scavenge outlet in the conical portion;
a wall adjacent the cyclone body and a bleed hole extending through the wall, with the bleed hole positioned radially inward of the scavenge 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 relative to the engine centerline.
3. The hanger of claim 1 , wherein the clean air outlet is aligned with the separator centerline.
4. The hanger of claim 1 , wherein the separator centerline forms an acute angle with the engine centerline.
5. The hanger of claim 1 , wherein the separator centerline extends at least radially.
6. The hanger of claim 1 , wherein the first surface, second surface, third surface, and cyclonic separator are integrally formed to define a unitary, monolithic body.
7. The hanger of claim 1 , wherein the bleed hole is fluidly coupled to a benign region located externally of the hanger.
8. A hanger for a turbine engine having an engine centerline, comprising:
a monolithic body comprising a first surface facing a cooling airflow and a second surface facing a heated airflow, the monolithic body defining a wall at least partially forming an air chamber, and also defining a cyclonic separator between the first surface and the wall comprising a cyclone body within the air chamber;
a dirty air inlet, a clean air outlet, and a scavenge outlet in the cyclone body, with the scavenge outlet positioned radially outward from the clean air outlet with respect to the engine centerline and emitting to the air chamber; and
a bleed hole extending through the wall and fluidly coupling the scavenge outlet to a benign region located externally of the hanger, with the bleed hole positioned radially inward of the scavenge outlet.
9. A shroud and hanger assembly for a turbine engine defining an engine centerline, 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 second surface relative to the engine centerline;
a cyclonic separator, comprising:
a cyclone body at least partially defined by the third surface and having a conical portion, a cylindrical portion, and a separator centerline extending through the conical portion and the cylindrical portion, with the separator centerline unaligned with the engine centerline;
a dirty air inlet and a clean air outlet in the cylindrical portion; and
a scavenge outlet in the conical portion;
a wall adjacent the cyclone body and a bleed hole extending through the wall, with the bleed hole positioned radially inward of the scavenge outlet; and
a hanger 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 hanger cooling air circuit and extending through the shroud between a shroud inlet on the inner surface and a shroud outlet on the heated surface.
10. The hanger of claim 9 , wherein the cyclone body includes opposing ends, with the scavenge outlet located at one end of the opposing ends and the clean air outlet located at the other end of the opposing ends of the cyclone body.
11. The shroud and hanger assembly of claim 9 , wherein the dirty air inlet is positioned radially outward of the clean air outlet relative to the engine centerline.
12. The shroud and hanger assembly of claim 9 , wherein the separator centerline extends at least radially.
13. The shroud and hanger assembly of claim 9 , wherein the shroud inlet is fluidly coupled to the clean air outlet, thereby fluidly coupling the shroud cooling circuit to the hanger cooling air circuit.
14. The shroud and hanger assembly of claim 9 , further comprising a baffle positioned between the second surface of the hanger and the inner surface of the shroud and forming at least one of a pre-impingement cavity or a post-impingement cavity.
15. The shroud and hanger assembly of claim 9 , wherein the bleed hole is fluidly coupled to a benign region located externally of the hanger.
