Panel support hanger for a turbine engine

1. A support hanger of a turbine engine, comprising:

a pin of the support hanger including a pin head;

a retainer pivotally connected to the pin head, the retainer including a seal bearing surface facing towards the pin head; and

a flexible seal including a retainer bearing surface sealingly engaging the seal bearing surface;

wherein the seal extends radially between a first seal segment and a second seal segment, and the first seal segment is radially displaced outward relative to the second seal segment; and wherein the second seal segment includes the retainer surface.

2. The support hanger of claim 1 , wherein the seal further includes a transition segment that extends radially and axially between the first seal segment and the second seal segment.

3. The support hanger of claim 1 , further comprising:

a collar including a threaded first collar segment and a second collar segment pivotally connected to the pin head;

wherein the retainer has a retainer bore, and the first collar segment is mated with a threaded portion of the retainer bore.

4. The support hanger of claim 3 , wherein

the pin head includes a parti-spherical collar bearing surface;

the second collar segment includes a parti-spherical pin bearing surface that engages the collar bearing surface to pivotally connect the collar to the pin head; and

the pin bearing surface at least partially defines a collar bore extending axially into the collar.

5. The support hanger of claim 4 , wherein the collar bearing surface is convex, and the pin bearing surface is concave.

6. The support hanger of claim 4 , wherein one or more slots extend radially though a sidewall of the collar, and axially through the pin engagement segment.

7. The support hanger of claim 6 , wherein

the collar includes an intermediate segment axially connecting the first collar segment and the second collar segment; and

the one or more slots extend axially into the intermediate segment to respective slot ends.

8. The support hanger of claim 3 , wherein

the retainer includes a first retainer segment and a second retainer segment;

the first retainer segment includes the seal bearing surface and the threaded portion of the retainer bore; and

at least a portion of the second collar segment is nested within a portion of the retainer bore in the second retainer segment.

9. The support hanger of claim 8 , wherein

the first retainer segment includes a flange and a base;

the flange extends radially out from the base and includes the seal bearing surface; and

the base includes the threaded portion of the retainer bore.

10. The support hanger of claim 9 , wherein the retainer flange comprises an arcuate cross-sectional geometry.

11. The support hanger of claim 9 , wherein

the retainer includes a plurality of torquing features arranged around the retainer base; and

the collar includes an anti-rotation feature arranged at an end of the first collar segment.

12. A turbine engine section, comprising:

a movable first panel of the turbine engine section;

a second panel;

a pin head fixedly connected to the first panel;

a retainer engaged pivotally to the head, the retainer including a seal bearing surface facing towards the pin head; and

an annular flexible seal engaged sealably between the seal bearing surface and the second panel;

wherein the seal extends radially between a first seal segment and a second seal segment;

wherein the first seal segment is axially displaced relative to the second seal segment, and the first seal segment axially engages the second panel; and

wherein the second seal segment includes a retainer bearing surface that sealingly engages the seal bearing surface.

13. The turbine engine section of claim 12 , wherein a gas path is defined between the first and the second panel.

14. The turbine engine section of claim 13 , wherein the pin head is in the gas path and the retainer projects through the second panel.

15. The turbine engine section of claim 14 , wherein the second panel has a first side opposed to the first panel and an opposite second side engaged directly to the flexible seal.

16. The turbine engine section of claim 12 , wherein the seal further includes a transition segment that extends radially and axially between the first and the second seal segments.

17. The turbine engine section of claim 12 , further comprising:

a collar including a threaded first collar segment and a second collar segment pivotally connected to the pin head;

wherein the retainer has a retainer bore, and the first collar segment is mated with a threaded portion of the retainer bore.

18. The turbine engine section of claim 17 , wherein

the pin head includes a parti-spherical collar bearing surface;

the second collar segment includes a parti-spherical pin bearing surface that engages the collar bearing surface to pivotally connect the collar to the pin head; and

the pin bearing surface at least partially defines a collar bore that extending axially into the collar.
