1. A rim-rotor assembly comprising:
an annular structure including a composite rim;
a hub;
blades projecting from the hub, tips of the blades contacting the annular structure, the blades configured to be loaded in compression against the annular structure; and
a thermal barrier in the annular structure, the thermal barrier being continuous and defining at least part of a radially inward surface of the annular structure, radially-outward surfaces of the tips of the blades contacting the thermal barrier, the thermal barrier being a thermal barrier coating.
