Turbine shroud assembly with separable pin attachment

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

• a carrier shaped to include an outer wall that extends circumferentially at least partway about an axis, a first support wall, a second support wall spaced axially from the first support wall, and a third support wall located axially between the first support wall and the second support wall,
• a seal segment shaped to include a runner that extends circumferentially partway around an axis, a forward mount flange that extends from the runner into a forward space between the forward support wall and the central support wall of the carrier, and an aft mount flange that extends from the runner into an aft space between the aft support wall and the central support wall of the carrier, and
• a mount assembly including a split-pin fastener that couples the seal segment with the carrier, the split-pin fastener being made up of (1) a first pin that extends axially through the first mount flange of the seal segment into both the first support wall and the third support wall of the carrier, (2) a second pin circumferentially aligned with the first pin that extends axially through the second mount flange of the seal segment into both the second support wall and the third support wall of the carrier, and (3) a connector that extends between and interconnects the first and second pins, the connector configured separate the first and second pins during use of the turbine shroud assembly in the gas turbine engine.

A method comprising

• providing a carrier, a seal segment, and a mount assembly, the carrier including an outer wall that extends circumferentially at least partway about an axis, a forward support wall that extends radially inward from the outer wall, an aft support wall spaced axially from the forward support wall that extends radially inward from the outer wall, and a central support wall located axially between the forward support wall and the aft support wall that extends radially inward from the outer wall, the seal segment including a runner that extends circumferentially partway around an axis, a forward mount flange that extends radially outward from the runner, and an aft mount flange that extends radially outward from the runner, and the mount assembly including a first split-pin fastener and a second split-pin fastener,
• locating the seal segment adjacent to the carrier so that the forward mount flange is between the forward support wall and the central support wall of the carrier and the aft mount flange that extends radially outward from the runner arranged between the aft support wall and the central support wall of the carrier,
• coupling the seal segment with the carrier by inserting the first split-pin fastener into the carrier and the seal segment and inserting the second split-pin fastener into the carrier and the seal segment at a location spaced apart circumferentially from the first split-pin fastener, and
• separating the first split-pin fastener and the second split-pin fastener into a forward pin that extends axially through the forward mount flange of the seal segment into both the forward support wall and the central support wall of the carrier and an aft pin circumferentially aligned with and aft of the forward pin that extends axially through the aft mount flange of the seal segment into both the aft support wall and the central support wall of the carrier so as to allow for independent loading of the forward pin and the aft pin of both the first and second split-pin assemblies.
