    摘要: A sealing arrangement for sealing between adjacent first and second exit frames each associated with a transition piece of a turbine. The arrangement includes a transition side seal having bristles that extend from a rail wherein the rail is bendable in a plurality of directions to accommodate bowing of an associated exit frame. The first exit frame includes a rail slot for receiving the rail. The second exit frame includes a bristle slot for receiving the bristles to form a seal between the first and second exit frames, wherein the bristle slot includes a bottom section. The bristles are separated from the bottom section by a bristle gap that is sized to accommodate movement of at least one transition piece to maintain a seal between the first and second exit frames or avoid damage to the bristles.

    摘要: A method of making a rub strip includes resin transfer molding an arcuate composite structure. The resin transfer molding step includes inserting a honeycomb core into a mold cavity having an arcuate base so that the honeycomb core assumes an arcuate shape. The resin transfer molding step further includes directing liquid resin into the mold cavity to form the composite structure comprising the liquid resin and the honeycomb core, and curing the liquid resin for a sufficient period of time. The resin transfer molding step further includes removing the composite structure from the mold. The method further includes repeating the resin transfer molding step until a sufficient number of arcuate composite structures are produced. The method further includes coupling a plurality of the arcuate composite structures together to form the rub strip.
