ABSTRACT:
A process for making and assembling a rotary regenerator comprising a ceramic core adapted to rotate upon its central axis and a ring gear surrounding the periphery of the core for purposes of driving the core rotatably including preparing and forming a yieldable compliant ring sandwiched between the ring gear and the periphery of the core to prevent stresses in the core caused by differential rates of expansion of the core and the ring during operation of the regenerator in a gas turbine engine and during processing of the regenerator and the regenerator drive ring.
