초록

Gas turbine engine systems involving hydrostatic face seals with anti-fouling provisioning are provided. In this regard, a representative turbine assembly for a gas turbine engine comprises: a turbine having a hydrostatic seal; the hydrostatic seal having a seal face, a seal runner, a carrier, and a biasing member; the seal face and the seal runner defining a high-pressure side and a lower-pressure side of the seal; the carrier being operative to position the seal face relative to the seal runner; and the biasing member being located on the lower-pressur...

1. A hydrostatic seal for a gas turbine engine comprising: a face seal having a seal face;a seal runner, wherein the seal face and the seal runner define a high-pressure side and a lower-pressure side of the hydrostatic seal;a carrier, the face seal being mounted to the carrier such that the carrier positions the seal face with respect to the seal runner, wherein the face seal has an air bearing supply channel extending from the high-pressure side to a side on which the seal face is located, and wherein the carrier has an orifice aligned with the air bea...
