    • 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-pressure side of the seal and being operative to bias the carrier such that interaction of the biasing member and gas pressure across the seal causes the carrier to position the seal face relative to the seal runner.
    • 提供了涉及具有防污供应的静水面密封件的燃气涡轮发动机系统。 在这方面,用于燃气涡轮发动机的代表性涡轮组件包括:具有静水压密封的涡轮机; 静压密封件具有密封面,密封流道,载体和偏置构件; 密封面和密封流道限定密封件的高压侧和低压侧; 所述载体可操作以相对于所述密封流道定位所述密封面; 并且所述偏置构件位于所述密封件的低压侧上并且可操作以偏压所述载体,使得所述偏置构件与所述密封件之间的气体压力的相互作用使所述载体相对于所述密封流道定位所述密封面。
