Abstract
The invention relates to a rotary heat exchanger. Springs 18, or compressed air, housed between the steel rim 2 and the cellular ceramic disk 1, 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 1 is subjected to abrupt accelerations and decelerations.
Claims1
A rotary heat exchanger for a gas turbine comprising a disc of cellular ceramic material having a peripheral lining of refractory material, a smooth metallic collar surrounding said lining in engagement therewith, an annular driving rim having a smooth radially inward surface surrounding said collar in radial spaced relation and a plurality of annular rows of radially disposed springs disposed in compression between said rim and said collar for transmitting driving torque from said rim to said collar and said disc.
