ABSTRACT:
A rotor for a gas turbine engine comprises an outer shell formed in hot pressed silicon nitride and having substantially uniform thickness in a direction parallel to the axis about which the rotor is rotatable and a heat resistant insert which can be either graphite or reaction sintered silicon nitride which fills the space within the shell and is attached to the shell. A row of blades which can be either hot pressed or reaction sintered silicon nitride can be attached to the periphery of the rotor by diffusion bonding.
