Abstract
Described is a seal segment (310) for a gas turbine engine, comprising: a gas facing wall (312) having a gas facing surface (314) and a first internal surface (316); an outboard wall (318) having an outboard facing surface (320) and a second internal surface (322) which is radially separated from the first internal surface with a gap therebetween; a first conduit (324) located between the first and second internal surfaces; and, a second conduit (326) located between the first and second internal surfaces, wherein the first and second conduits are radially separated by a party wall (328).
Claims15
A seal segment for a gas turbine engine, comprising:
- a gas facing wall having a gas facing surface and a first internal surface;
- an outboard wall having an outboard facing surface and a second internal surface which is radially separated from the first internal surface by a gap;
- a first conduit located between the first and second internal surfaces;
- and,
- a second conduit located between the first and second internal surfaces, wherein the first and second conduits are radially separated by a party wall that precludes airflow therebetween.
A gas turbine engine, comprising:
- a turbine stage having a plurality of circumferentially adjacent seal segments defining a boundary wall for a main gas path, each seal segment of the plurality of circumferentially adjacent seal segments having a gas facing wall having a gas facing surface and a first internal surface;
- an outboard wall having an outboard facing surface and a second internal surface which is radially separated from the first internal surface by a gap;
- a first conduit located between the first and second internal surfaces;
- and
- a second conduit located between the first and second internal surfaces, wherein the first and second conduits are radially separated by a party wall, each of the first and second conduits having an inlet and an outlet, wherein
- the inlet of the first conduit is in fluid communication with a first air source having a first temperature and the second conduit is in fluid communication with a second air source having a second temperature, wherein the first temperature is greater than the second temperature.
