Abstract

A support hanger is provided for a turbine engine. The support hanger includes a pin with a pin head, a retainer and a flexible seal. The retainer is pivotally connected to the pin head. The retainer includes a seal bearing surface facing towards the pin head. The seal includes a retainer bearing surface sealingly engaging the seal bearing surface.

First claim

What is claimed is:

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.
