Abstract

A turbine rotor having a number of metallic attachment pieces for coupling a plurality of ceramic blades to a metallic rotor disk. The blades have roots which are received within grooves formed in the attachment pieces. Each attachment piece has passage means therethrough cooperating with passages in the rotor disk for receiving a coolant for cooling the attachment pieces without causing the coolant to contact the ceramic blades. The attachment pieces keep the rotor disk isolated from the hot gases which contact the ceramic blades.
