摘要： A shroud hanger assembly or shroud assembly is provided for a gas turbine engine wherein a hanger includes a radially depending and axially extending arm. The arm or retainer engages a pocket formed in a shroud so as to retain the shroud in a desired position relative to the hanger. An aft retaining structure is provided on the hanger and provides a seat for a seal structure which biases the retainer so that the arm of the hanger maintains engagement in the shroud pocket. A baffle may be utilized at the hanger to cool at least some portion of the shroud.

摘要： A shroud hanger assembly or shroud assembly is provided for components which may be formed of materials having differing coefficient thermal expansion. The assembly includes a multi-piece hanger including a shroud positioned in a cavity between a first hanger portion and a second hanger portion. A shroud may be formed of a low coefficient of thermal expansion material which may have a differing coefficient thermal expansion than the material defining the shroud hanger. The shroud is deflected by an axial force acting between the hanger and the shroud which also forms a seal. The seal compensates for differing rates of thermal growth between the shroud and the hanger throughout the engine operating envelope.

摘要： In one aspect the present subject matter is directed to a system for cooling a turbine shroud. The system includes a cooling medium source that provides a cooling medium, and a turbine shroud support assembly that includes a shroud support ring. A shroud seal is coupled to the turbine shroud support assembly. The shroud seal includes a back side surface and an inner surface. A pin extends at least partially through the shroud support ring towards the back side surface. The pin includes a flow passage having an inlet that is in fluid communication with the cooling medium source and an aperture that is disposed downstream from the inlet. The aperture is oriented to direct a flow of the cooling medium out of the flow passage in a flow direction that is non-perpendicular to the back side surface of the shroud seal.

摘要： A shroud hanger assembly or shroud assembly is provided for dimensionally incompatible components wherein the assembly includes a multi-piece hanger, for example having a forward hanger portion and a rearward hanger portion. A cavity is formed between the parts; wherein a shroud may be positioned which is formed of a low coefficient of thermal expansion material. The hanger and shroud may be formed of the same material or differing materials in order to better match the thermal growth between the hanger and the shroud. When the shroud is positioned within the hanger opening or cavity, one of the forward and rearward hanger portions may be press fit or otherwise connected into the other of the forward and rearward hanger portion.
