SEGMENTED TURBINE SHROUD WITH SEALS |
摘要 |
A turbine shroud for a gas turbine engine includes a plurality of shroud segments arranged around a central axis. Each shroud segment includes a carrier segment, a blade track segment, and a radial seal element that seals a radial interface between the carrier segment and the blade track segment. The turbine shroud further includes a plurality of circumferential seals that seal circumferential interfaces between the shroud segments. |

1. A segmented turbine shroud that extends around a central axis, the segmented turbine shroud comprising
a first shroud segment including a first carrier segment and a first blade track segment, the first blade track segment made from a ceramic-matrix-composite material and coupled to the first carrier segment, a second shroud segment arranged circumferentially adjacent to the first shroud segment around the central axis, the second shroud segment including a second carrier segment and a second blade track segment, the second blade track segment made from a ceramic-matrix-composite material and coupled to the first carrier segment, and a circumferential seal arranged between the first shroud segment and the second shroud segment to block gasses from passing through a circumferential interface of the first shroud segment and the second shroud segment, the circumferential seal including a first seal support coupled to the first shroud segment, a second seal support coupled to the second shroud segment, and a seal element that extends from the first seal support to the second seal support. |
