Abstract: A method of assembling a rotor is provided, in which each rotor disk comprising a connecting element. The method includes: (a) applying heat to a localized region of a first rotor disk of a plurality of rotor disks to selectively deflect a first connecting element of the first rotor disk, wherein the first rotor disk is stationary during heating; (b) installing the first rotor disk onto a rotor stack containing at least one rotor disk; and (c) repeating steps (a) and (b) for each rotor disk of the plurality of rotor disks; and (d) allowing the rotor disks, when stacked, to cool. When cooled, the respective connecting element of each rotor disk that has been selectively deflected contracts into an interference fit with an adjacent rotor disk. A system for selectively heating a localized region of a rotor disk is also provided.

Abstract: Embodiments of the present disclosure provide a control system including: a power wrench; and a controller operatively connected to the power wrench, wherein the controller is configured to perform actions including: directing an operative head of the power wrench to turn in response to a pressure-angle derivative of the operative head being below a predetermined threshold, defining an origin at an angular position of the operative head where the pressure-angle derivative of the operative head exceeds the predetermined threshold, directing the operative head to turn by an angular step in response to: the pressure-angle derivative of the operative head exceeding the predetermined threshold, and an angular differential of the operative head being less than a target value; and directing the operative head to cease turning in response to the angular differential of the operative head being approximately equal to or greater than the target value.
