Abstract
An inner mounting ring () for gas turbine flow path components such as shroud ring segments (). The inner ring () may be mounted to an outer ring () on radially slidable mounts () that maintain the two rings () in coaxial relationship, but allows them to thermally expand at different rates. This allows matching of the radial expansion rate of the inner ring () to that of the turbine blade tips (), thus providing reduced clearance () between the turbine blade tips () and the inner surface of the shroud ring segments () under all engine operating conditions. The inner ring () may be made of a material with a lower coefficient of thermal expansion than that of the outer ring ().
