Abstract

Claims (23)

1. A turbine engine defining a circumferential direction, comprising:

a rotor;

a stator comprising a carrier;

a seal assembly disposed between the rotor and the stator, the seal assembly comprising a plurality of seal segments supported at least in part by the carrier, the plurality of seal segments having a first seal segment and a second seal segment, a first engagement assembly extending radially from the carrier to the first seal segment, and a second engagement assembly extending radially from the carrier to the second seal segment, wherein the first and second seal segments each having a seal face forming a fluid bearing with the rotor; and

a seal support assembly comprising a tangential spring extension disposed radially between the carrier and the first and second seal segments, wherein the tangential spring extension extends circumferentially between the first seal segment and the second seal segment for biasing the first seal segment away from the second seal segment in the circumferential direction.

2. The turbine engine of claim 1 , wherein the first seal segment extends between a first circumferential end and a second circumferential end, wherein the second seal segment extends between a first circumferential end and a second circumferential end of the second seal segment, wherein the tangential spring extension is coupled to the first seal segment proximate the second circumferential end and to the second seal segment proximate the first circumferential end.

3. The turbine engine of claim 1 , wherein the tangential spring extension is engaged with the carrier to support the seal assembly.

4. The turbine engine of claim 1 , wherein the tangential spring extension is engaged with the carrier through a radial spring operable to bias the tangential spring extension outward along a radial direction.

5. The turbine engine of claim 4 , wherein the first seal segment defines a first circumferential end adjacent to the second seal segment, wherein the wherein the second seal segment defines a second circumferential end adjacent to the first seal segment, and wherein the tangential spring extension is engaged with the first and second circumferential ends.

6. The turbine engine of claim 1 , further comprising:

a turbine, wherein the rotor is a turbine rotor of the turbine.

7. The turbine engine of claim 6 , wherein the seal assembly includes a high-pressure side and a low-pressure side, and wherein the high-pressure side is located forward of the low-pressure side.

8. The turbine engine of claim 6 , wherein the seal assembly includes a high-pressure side and a low-pressure side, wherein the first seal segment includes a lip and a body, wherein the lip extends from the body along an axial direction of the turbine engine on the high-pressure side, and wherein the lip includes an outer pressurization surface along a radial direction of the turbine engine.

9. The turbine engine of claim 1 , further comprising:

a compressor and a turbine arranged in serial flow order and together defining in part a working gas flowpath, wherein the rotor is a turbine rotor of the turbine and wherein the seal support assembly is in airflow communication with a portion of the working gas flowpath defined by the compressor.

10. A turbine engine defining a circumferential direction and a radial direction, comprising:

a rotor;

a stator comprising a carrier;

a seal assembly disposed between the rotor and the stator, the seal assembly comprising a plurality of seal segments supported at least in part by the carrier, the plurality of seal segments having a first seal segment and a second seal segment, the first and second seal segments each having a seal face forming a fluid bearing with the rotor; and

a seal support assembly comprising:

a first engagement assembly extending radially from the first seal segment to the carrier, the first engagement assembly operable to bias the first seal segment along the radial direction;

a second engagement assembly extending radially from the second seal segment to the carrier, the second engagement assembly operable to bias the second seal segment along the radial direction; and

a tangential spring extension disposed radially between the carrier and the first and second seal segments, wherein the tangential spring extension extends circumferentially between the first engagement assembly and the second engagement assembly for biasing the first seal segment relative to the second seal segment in the circumferential direction.
