Claim 10:
11. A turbine shroud assembly for use with a gas turbine engine, the turbine shroud assembly comprising:
a carrier segment arranged circumferentially at least partway around a central axis of the gas turbine engine,
a blade track segment made of ceramic matrix composite materials and supported by the carrier segment, the blade track segment including a shroud wall that extends circumferentially partway around the central axis, a first attachment flange that extends radially outward away from the shroud wall into the carrier segment, and a second attachment flange spaced apart axially from the first attachment flange that extends radially outward away from the shroud wall into the carrier segment, and
a retainer that extends axially into the carrier segment and through the first attachment flange and the second attachment flange of the blade track segment, and
wherein the first attachment flange of the blade track segment includes a first axially aft-facing surface that faces the second attachment flange and extends radially outward and axially forward away from the shroud wall at a first angle relative to a first radial plane that is orthogonal to the central axis of the gas turbine engine, the second attachment flange of the blade track segment includes a first axially forward-facing surface that faces the first attachment flange and extends radially outward and axially aft away from the shroud wall at a second angle relative to a second radial plane parallel to the first radial plane, and
wherein the second attachment flange of the blade track segment includes a second axially aft-facing surface opposite the first axially forward-facing surface that extends away from the shroud wall at a third angle relative to a third radial plane that is parallel to the first and second radial planes and the third angle is different from the first angle and the second angle.
