TURBINE SHROUD SEGMENT WITH LOAD DISTRIBUTION SPRINGS

摘要

A turbine shroud adapted for use in a gas turbine engine includes a plurality of metallic carrier segments and a plurality of blade track segments mounted to corresponding metallic carrier segments. Cooling air is directed onto the blade track segments to cool the blade track segments when exposed to high temperatures in a gas turbine engine.

1. A turbine shroud segment adapted for use in a gas turbine engine, the turbine shroud segment comprising
a carrier segment comprising metallic materials, the carrier segment formed to include an attachment-receiving space, a blade track segment comprising ceramic matrix composite materials, the blade track formed to include a runner shaped to extend at least partway around a central axis and an attachment portion that extends radially outward from the runner into the attachment-receiving space formed by the carrier segment, an attachment assembly including an attachment post that extends from the carrier segment through an attachment hole formed in the attachment portion of the blade track segment, an attachment support coupled to the attachment post to block withdrawal of the attachment post through the attachment hole, and a load distributor configured to distribute clamp force applied by the attachment post and the attachment support along the attachment portion of the blade track segment.
