First Claim
Patent Images
1. A segmented turbine shroud that extends around a central axis, the segmented turbine shroud comprising:
- a carrier segment formed to include a dovetail slot that opens inwardly in a radial direction toward the central axis,a blade track segment comprising ceramic-containing materials, the blade track segment being formed to include a runner that extends partway around the central axis and a flange that extends radially outward from the runner, anda track retention assembly including retainer blocks that receive at least a portion of the flange included in the blade track segment,wherein the retainer blocks are positioned in the dovetail slot of the carrier segment and cooperate to provide a dovetail shape corresponding to the dovetail slot and being sized to block movement of the track retention assembly out of the dovetail slot.

12. A turbine shroud segment comprising:
-
a carrier formed to include a dovetail slot, a blade track comprising ceramic-containing materials, the blade track segment formed to include a runner and a flange that extends radially outward from the runner, and a track retention assembly including two retainer blocks that receive at least a portion of the flange of the blade track, the retainer blocks being positioned in the dovetail slot of the carrier, and that cooperate to provide a dovetail shape corresponding to the dovetail slot and being sized to block radial movement of the track retention assembly radially out of the dovetail slot, wherein each retainer block includes an exterior surface configured to engage with a surface of the dovetail slot of the carrier, and an interior surface configured to engage an exterior surface of the flange. - View Dependent Claims (13, 14)
