Abstract: A rotor assembly includes a plurality of wheels and a tie bolt that extends through the plurality of wheels and applies a compressive force to the plurality of wheels. The tie bolt includes a first segment with a first stiffness and a second segment with a second stiffness to allow for thermal growth of the plurality of wheels.

Abstract: A labyrinth seal system comprises a knife element and a stator element, the knife element having a plurality of teeth radially extending from a base and the stator element having a radially inner surface configured to interact with the plurality of teeth to create a seal. The knife element is axially constrained by and rotationally coupled to a turbine component, but has a degree of freedom in the radial direction with respect to that component.

Abstract: A nozzle for oil dispensing that includes; a connector, where the connector connects the nozzle to a hose during use; an outlet, where the outlet includes an opening for the dispensing of oil through the nozzle; a handle, where the handle activates the dispensing of the oil; and a digital readout placed on the face of the nozzle below handle, where the digital readout is visible during use. Further the present invention includes a method of volume measurement for an oil distribution nozzle that includes the steps of: integrating a measurement display into a Scully nozzle; providing a digital readout on the measurement display; placing the measurement display under a handle of the Scully nozzle; and measuring oil flow volume through the Scully nozzle.
