ABSTRACT:
A rotor-shaft assembly includes a ceramic solid hubbed turbine rotor having an integral stub shaft interference fit within one end of a generally cylindrically shaped sleeve member. The sleeve member defines a hub portion adapted to mate with a piston ring seal and a coaxial bore therethrough. The interference fit, which is defined by the change in the diameter of the bore, schedules the compressive forces acting on the stub shaft. A metal shaft is brazed within the other end of the sleeve member in a torque transmitting relationship.
