Mounting apparatus for low-ductility turbine shroud

A shroud apparatus for a gas turbine engine, comprising:

• an annular metallic hanger including an arcuate body and axially-spaced-apart forward and aft inner legs extending radially inward from the body, the forward inner leg including an arcuate forward bearing surface and the aft inner leg including an arcuate aft bearing surface;
• and
• a shroud segment disposed inboard of the hanger, comprising low-ductility material and having an inner wall defining an arcuate inner flowpath surface and axially-spaced-apart forward and aft walls extending radially outward from the inner wall;
• wherein the shroud segment is mounted relative to the hanger such that the forward bearing surface bears against the forward wall and the aft bearing surface bears against the aft wall, such that the shroud segment and the hanger cooperatively define a plenum therebetween.
