Abstract
An apparatus for mounting a refractory component such as a turbine shroud ring segment () with a ceramic core () onto a combustion turbine engine structure (). The ring segment has a ceramic matrix composite skin (), and optionally, a thermal insulation layer (). A pin () is inserted through a bore () in the core and through an attachment bar () with ends received in wells () in the core. The attachment bar may be attached to a backing member, or tophat (), by a biasing device () that urges the refractory component snugly against the backing member to eliminate vibration. The backing member and refractory component have mating surfaces that may include angled sides (S,). The backing member is attached to the engine structure. Turbine shroud ring segments can be attached by this apparatus to a surrounding structure to form a shroud ring.
