Abstract
A gas turbine engine in which a long length-to-diameter (L/D) flexible shaft is used to connect two high speed shafts in order to tolerate misalignment. In order to reduce the overall system length, a smaller diameter flexible shaft is contained within but not in contact with a larger diameter primary turbomachinery shaft such that the smaller flexible shaft adjoins to the primary shaft aft of the primary shaft bearing. This design reduces a length of the overall system and reduces additional cost associated with a flex bellows or spline.
