    摘要： A seal assembly having a flexible cloth seal which includes a shim assemblage surrounded by a cloth assemblage. A first tubular end portion, such as a gas turbine combustor, includes a longitudinal axis and has smooth and spaced-apart first and second surface portions defining a notch therebetween which is wider at its top than at its bottom and which extends outward from the axis. The second surface portion is outside curved, and a first edge of the cloth seal is positioned in the bottom of the notch. A second tubular end portion, such as a first stage nozzle, is located near, spaced apart from, and coaxially aligned with, the first tubular end portion. The second tubular end portion has a smooth third surface portion which surrounds at least a portion of the first tubular end portion and which is contacted by the cloth seal.

    摘要： A brush seal segment is mounted within a pressure vessel and against an arcuate surface of an element to provide a seal between regions on opposite sides of the seal at different pressures. By vibrating the vessel through a range of frequencies, natural frequencies of the brush seal under pressure loading can be ascertained. Additionally, by adjusting interference between the arcuate surface and the bristle tips, natural frequencies of the brush seal under various interference loadings can likewise be ascertained. The pressure vessel has mounts for attaching the vessel to a shaker table to facilitate vibrating the vessel through the range of frequencies.

    摘要： According to one aspect of the invention, a turbine assembly includes a first stationary component, a second stationary component positioned radially outside the first stationary component, a first key feature on the first stationary component configured to mate to a second key feature on the second stationary component and a seal assembly positioned between the first and second key features to reduce fluid flow between the first and second key features. The seal assembly includes a V-shape member and a second member adjacent to the V-shape member, the second member and V-shape member having different rates of thermal expansion. The seal assembly also includes a latch feature coupled to the V-shape member configured to expand the seal assembly from a compressed state to an expanded sealing state when the seal assembly is subject to an elevated temperature.
