Abstract
An improved rotor for a gas turbine engine wherein the rotor has a plurality of ceramic turbine blades coupled by attachment pieces of high-temperature metal to a rotor disk. Each attachment piece has a root received in a corresponding groove in the outer periphery of the rotor disk. Also, each attachment piece is made to couple a pair of turbine blades to the rotor disk, the attachment piece having a pair of axially spaced, radially extending walls, each wall having a hole therethrough and the holes of the walls being aligned with each other. The roots of the two blades for each attachment piece are positioned between its spaced wall and the roots have cooperating projecting parts which engage each other and form a recess through which a pin extends when the ends of the pin are in the holes of the end walls. The roots of the blades of adjacent attachment pieces abut each other to keep the blades from moving laterally relative to respective attachment pieces.
