Turbine shroud assembly with inter-segment damping

A turbine shroud assembly for use with a gas turbine engine, the turbine shroud assembly comprising:

• a first shroud segment including a first carrier segment arranged circumferentially at least partway around a central axis and a first blade track segment supported by the first carrier segment to define a first portion of a gas path of the turbine shroud assembly, the first blade track segment having a first shroud wall that extends circumferentially partway around the central axis and a first attachment feature that extends radially outward from the first shroud wall,
• a second shroud segment arranged circumferentially adjacent the first shroud segment about the central axis, the second shroud segment including a second carrier segment arranged circumferentially at least partway around the central axis and a second blade track segment supported by the second carrier segment to define a second portion of the gas path of the turbine shroud assembly, the second blade track segment having a second shroud wall that extends circumferentially partway around the central axis and a second attachment feature that extends radially outward from the second shroud wall, and
• a seal assembly configured to block gases from escaping the gas path radially between the first shroud segment and the second shroud segment, the seal assembly including a strip seal and a damping coil, the strip seal extending axially along the first shroud wall and the second shroud wall, and the damping coil arranged along the strip seal to apply a radial inward force to the strip seal so that the strip seal is urged radially inwardly to maintain engagement of the strip seal with the first shroud wall and the second shroud wall.

A method of assembling a turbine shroud assembly for use with a gas turbine engine comprising:

• assembling a first shroud segment by coupling a first blade track segment with a first carrier segment to support the first blade track segment radially inward of the first carrier segment,
• assembling a second shroud segment by coupling a second blade track segment with a second carrier segment to support the second blade track segment radially inward of the second carrier segment,
• locating a strip seal on a first radial outer surface of the first blade track segment and a second radial outer surface of the second blade track segment,
• locating a damping coil radially between the first carrier segment and the strip seal so that the damping coil engages the first carrier segment and the strip seal, and
• applying a radial inward force to the strip seal with the damping coil to maintain engagement of the strip seal with the first radial outer surface of the first blade track segment and the second radial outer surface of the second blade track segment in response to radial misalignment of the first blade track segment relative to the second blade track segment.
