Abstract

See full text

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.
