Abstract
A turbine shroud for a gas turbine engine is adapted to extend around a bladed turbine wheel and prevent gasses from passing over the blades without interacting with the blades. The turbine shroud includes a carrier, a blade track, and a plurality of biasing members. The biasing members locate the blade track relative to the carrier.

A turbine shroud for a gas turbine engine that extends around a central axis, the turbine shroud comprising
- a metallic carrier that extends around the central axis,
- a ceramic-containing composite blade track coupled to the metallic carrier, and
- a plurality of biasing members arranged between the metallic carrier and the ceramic-containing composite blade track to bias the ceramic-containing composite blade track outwardly in a radial direction away from the central axis to locate the ceramic-containing composite blade track relative to the metallic carrier.
A turbine shroud that extends around a central axis, the turbine shroud comprising
- a carrier,
- a blade track segment coupled to the carrier, and
- a plurality of biasing members arranged between the carrier and the blade track segment to bias the composite blade track segment outwardly in a radial direction away from the central axis to locate the blade track segment relative to the carrier.
A method of making a turbine shroud, the method comprising
- mounting a ceramic-containing composite blade track segment to a metallic carrier so that a retention head of the blade track segment is received in the metallic carrier and a runner of the metallic carrier is located radially inward of the metallic carrier relative to a central axis about which the metallic carrier extends, and
- arranging a plurality of biasing members between the blade track segment and the metallic carrier to bias the blade track away from the central axis.
