Rotary heat exchanger, in particular for a gas turbine

Patent ·
OSTI ID:5258530
A rotary heat exchanger for a gas turbine consists of a disc of cellular ceramic material having a peripheral lining of refractory material, a smooth metallic collar surrounding the lining, an annular driving rim having a smooth radially inward surface surrounding the collar in radial spaced relation and annular rows of radially disposed springs disposed in compression between the rim and the collar for transmitting driving torque from the rim to the collar and the disc. Springs or compressed air, housed between the steel rim and the cellular ceramic disk, exert a compressive prelateral tightness over about one-third of the surface, for the passing of the cool air of admission. The remainder of the disk is passed through by hot exhaust gases. A gas turbine, in particular for a lorry, wherein the disk is subjected to abrupt accelerations and decelerations is studied.
