摘要： The damper system includes a ceramic composite shroud in part defining the hot gas path of a turbine and a spring-biased piston and damper block which bears against the backside surface of the shroud to tune the vibratory response of the shroud relative to pressure pulses of the hot gas path in a manner to avoid near or resonant frequency response. The damper block has projections specifically located to bear against the shroud to dampen the frequency response of the shroud and provide a thermal insulating layer between the shroud and the damper block.

摘要： A bucket tip clearance control system forms part of a turbomachinery apparatus including a casing, an outer shroud coupled with the casing, and an inner shroud coupled with the outer shroud. The tip clearance control system includes a flow circuit for a thermal medium defining a flow path within the outer shroud. A thermal medium source delivers the thermal medium to the flow circuit in a predefined condition according to operating parameters of the turbomachinery apparatus. The temperature of the outer shroud is controlled according to the predefined condition of the thermal medium. By accurately controlling the temperature of the outer shroud, bucket tip clearance can be controlled and optimized during all of the various operation stages of turbomachinery.

摘要： A plurality of arcuate, circumferentially extending leaf seal segments form an annular seal spanning between annular sealing surfaces of inner and outer casings of a turbine. The ends of the adjoining seal segments have circumferential gaps to enable circumferential expansion and contraction of the segments. The end of a first segment includes a tab projecting into a recess of a second end of a second segment. Edges of the tab seal against the sealing surfaces of the inner and outer casings have a narrow clearance with opposed edges of the recess. An overlying cover plate spans the joint. Leakage flow is maintained at a minimum because of the reduced gap between the radially spaced edges of the tab and recess, while the seal segments retain the capacity to expand and contract circumferentially.
