Abstract

Systems, methods and apparatus for controlling gas leakage in a turbine are provided. A plurality of seals may be provided in series, where each of the plurality of seals may be operable to reduce gas backflow from an inlet of a turbine component. Further, one or more channels may be provided that are operable to direct at least a portion of the gas backflow from respective points within the plurality of seals to corresponding points within a gas flow path of the turbine. The at least a portion of the gas backflow may be directed to the points within the gas flow path through the one or more channels. Additionally, the diameters of the plurality of seals may be optimized to at least partially balance the net thrust generated by the gas flow path of the turbine.
