ABSTRACT:
In accordance with the invention there is provided a heat exchanger for transferring heat from the exhaust gases of a turbine engine to the intake air for the engine, the heat exchanger comprising a rotatable cylindrical ceramic body having axially extending passages therethrough for passage of the exhaust gases in one direction on one diametric half of the body and for passage of the intake air in the other direction on the other diametric half of said body, one axial end of the body thereby being at a higher temperature than the other axial end of the body, an annulus of ceramic bordering a cylindrical surface of the body and having a radially extending annular flange bonded to the cylindrical surface of the body at the low temperature axial end thereof, there being an annular gap between the ceramic annulus and the cylindrical surface of the body at the high temperature axial end thereof and an annulus of resilient sealing material in the annular gap.
