ABSTRACT:
A rubbing contact fluid seal member is provided on the hot side of a rotary regenerator of a gas turbine engine to prevent high temperature exhaust gases from mixing with counterflowing combustion air, maintaining rubbing contact with a radial surface of a rotatable matrix. The seal member is formed with a heat-resistant layer of silicon carbide at a part of its surface which is in direct contact with the high temperature exhaust gas.
