Abstract
An assembly adapted for use in a gas turbine engine includes a carrier and a blade track segment. The carrier extends at least partway about an axis. The blade track segment is supported by the carrier radially relative to the axis to define a portion of a gas path of the assembly.

A turbine shroud adapted for use in a gas turbine engine, the turbine shroud comprising
- a first turbine shroud segment including a first carrier comprising metallic materials and arranged to extend circumferentially at least partway about a center axis, a first blade track segment comprising ceramic matrix composite materials, and a first intermediate carrier configured to couple the first blade track segment to the first carrier, the first blade track segment formed to include a first runner shaped to extend circumferentially partway around the center axis, a first fore mount post that extends radially outward from the first runner, and a first aft mount post that extends radially outward from the first runner, and the first aft mount post spaced apart axially from the first fore mount post to define a first channel therebetween, and the first intermediate carrier is arranged axially in the first channel of the first blade track segment, and
- a second turbine shroud segment arranged circumferentially adjacent to the first turbine shroud segment, the second turbine shroud segment including a second carrier comprising metallic materials and arranged to extend circumferentially at least partway about the center axis, a second blade track segment comprising ceramic matrix composite materials, and a second intermediate carrier configured to couple the second blade track segment to the second carrier, the second blade track segment formed to include a second runner shaped to extend circumferentially partway around the center axis, a second fore mount post that extends radially outward from the second runner, and a second aft mount post that extends radially outward from the second runner, and the second aft mount post spaced apart axially from the second fore mount post to define a second channel therebetween, and the second intermediate carrier is arranged in the second channel of the second blade track segment,
- wherein the first intermediate carrier includes a first intermediate carrier body arranged between the first fore mount post and the second fore mount post in the first channel and a flange that extends circumferentially from a circumferential end of the first intermediate carrier body and engages an adjacent circumferential end of a second intermediate carrier body included in the second intermediate carrier to form an overlap between the first intermediate carrier body and the second intermediate carrier body that closes a gap between the first turbine shroud segment and the second turbine shroud segment and allows relative movement therebetween during operation of the gas turbine engine.
A turbine shroud adapted for use in a gas turbine engine, the turbine shroud comprising
- a first turbine shroud segment including a first carrier arranged to extend circumferentially at least partway about a center axis, a first blade track segment, and a first intermediate carrier configured to couple the first blade track segment to the first carrier, wherein the first blade track segment formed to include a first runner shaped to extend circumferentially partway around the center axis and a first attachment portion that extends radially outward from the first runner, and
- a second turbine shroud segment arranged circumferentially adjacent to the first turbine shroud segment, the second turbine shroud segment including a second carrier arranged to extend circumferentially at least partway about the center axis, a second blade track segment, and a second intermediate carrier configured to couple the second blade track segment to the second carrier, wherein the second blade track segment formed to include a second runner shaped to extend circumferentially partway around the center axis and a second attachment portion that extends radially outward from the second runner,
- wherein the first intermediate carrier is shaped to include a first intermediate carrier body coupled with the first attachment portion of the first blade track segment, a plurality of first retainers that extend radially and couple the first carrier with the first intermediate carrier body, and a flange that extends circumferentially from a circumferential end the first intermediate carrier body and engages an adjacent circumferential end of a second intermediate carrier body included in the second intermediate carrier to form an overlap therebetween.
A method comprising
- providing a first turbine shroud segment including a first carrier, a first blade track segment, and a first intermediate carrier, the first blade track segment including a first runner shaped to extend partway around an axis, a first fore mount post that extends radially outward from the first runner, and a first aft mount post spaced apart axially from the first fore mount post that extends radially outward from the first runner, and the first intermediate carrier including a first intermediate carrier body, a flange that extends circumferentially from a circumferential end of the first intermediate carrier body, and pins,
- providing a second turbine shroud segment including a second carrier, a second blade track segment, and a second intermediate carrier, the second blade track segment including a second runner shaped to extend partway around the axis, a second fore mount post that extends radially outward from the second runner, and a second aft mount post spaced apart axially from the second fore mount post that extends radially outward from the second runner, and the second intermediate carrier including a second intermediate carrier body and pins,
- arranging the first intermediate carrier body axially between the first fore mount post and the first aft mount post of the first blade track segment,
- inserting the pins axially through the first fore mount post, the first intermediate carrier body, and the first aft mount post to couple the first blade track segment to the first intermediate carrier body,
- arranging the first intermediate carrier in an attachment space formed in the first carrier,
- coupling the first intermediate carrier with the first carrier,
- arranging the second intermediate carrier body axially between the second fore mount post and the second aft mount post of the second blade track segment,
- inserting the pins axially through the second fore mount post, the second intermediate carrier body, and the second aft mount post to couple the second blade track segment to the second intermediate carrier body,
- arranging the second intermediate carrier in an attachment space formed in the second carrier,
- coupling the second intermediate carrier with the first carrier, and
- arranging the second turbine shroud segment circumferentially adjacent to the first turbine shroud segment in the gas turbine engine so that the flange of the first intermediate carrier engages an adjacent circumferential end of the second intermediate carrier body to form an overlap therebetween.
