Abstract
A regenerative heat-exchanger of a gas turbine with a ceramic heat-exchanger disk, a metallic toothed rim substantially coaxially surrounding the heat-exchanger disk under formation of an annular space, compression springs arranged in the annular space which are supported under prestress, on the one hand, against the inside of the toothed rim and, on the other, against the outside of curved entrainment plate means; each entrainment plate means includes a support member and an adherent layer whose concave inner side abuts at the edge of the heat-exchanger disk, whereby the adherent layer essentially consists of metal fibers which form a plastically deformable felt-like adherent layer providing a good frictional engagement to transmit the driving torque to the heat-exchanger disk.

A regenerative heat-exchanger of a gas turbine comprising a ceramic heat-exchanger disk, a metallic toothed rim substantially coaxially surrounding said heat-exchanger disk under formation of an annular space, compression spring means arranged in said annular space, which are supported under prestress, on the one hand, against the inside of the toothed rim and, on the other, against the outside of curved entrainment plate means, said entrainment plate means including a support member and an adherent layer whose concave inner side abuts at the edge of the heat-exchanger disk, characterized in that the adherent layer essentially consists of metal fibers which form a plastically deformable, felt-like adherent layer.
