ABSTRACT:
Disclosed is a novel rotary heat exchanger and heat exchange system for use in gas turbine engines and other environments. The heat exchanger includes a ceramic disk having a ring gear extending about the outer circumference thereof. The ring gear is joined to the ceramic disk by means of an elastomeric member. However, means are provided for keeping the elastomeric member below its degradation temperature. These means include the provision of filler material for blocking a plurality of passages at a first and second face of the disk thus forming annular bands concentric therewith on opposite faces of the disk. A plurality of passages at the periphery of the disk radially outwardly of the bands are unobstructed by the filler material such that cooling air may flow therethrough so as to keep the elastomeric material at the desired temperature.
