ABSTRACT:
A power turbine rotor drive shaft has a flanged end connected to a turbine rotor disc supported by a rotor bearing housing so as to be rotatably supported by a turbine rotor bearing assembly at one end of the shaft and including a second splined end thereon coupled to a shaft extension supported at one portion thereof by a roller bearing shaft assembly and wherein the shaft has a predetermined fundamental bending vibration mode between the rotor bearing assembly and the shaft bearing assembly and wherein an insert sleeve is shrunk-fit within an inside diameter of the shaft to stiffen the shaft so as to increase the fundamental bending vibration mode of the resultant composite shaft without excessively increasing the weight of the composite shaft.
