Abstract: This disclosure describes machine learning techniques for capturing human knowledge for performing a task. In one example, a video device obtains video data of a first user performing the task and one or more sensors generate sensor data during performance of the task. An audio device obtains audio data describing performance of the task. A computation engine applies a machine learning system to correlate the video data to the audio data and sensor data to identify portions of the video, sensor, and audio data that depict a same step of a plurality of steps for performing the task. The machine learning system further processes the correlated data to update a domain model defining performance of the task. A training unit applies the domain model to generate training information for performing the task. An output device outputs the training information for use in training a second user to perform the task.

Abstract: The present application provides an extraction system for removing a retaining pin from a turbine engine. The extraction system may include a pin extraction fixture and a drill such that the pin extraction fixture positions the drill about the retaining pin. The pin extraction fixture may include a collet and one or more expanders positioned thereabout.

Abstract: A manipulator assembly for supporting and manipulating a nozzle segment, for example of a gas turbine or a steam turbine. The assembly includes a vertical support member and a horizontal support member. The vertical support member is mounted for selective vertical displacement relative to a base and the horizontal support member is operatively coupled at a proximal end thereof to the vertical support member so as to be vertically displaced therewith and so as to be pivotable about a vertical axis of the vertical support member. A nozzle segment fixture is operatively coupled to a distal end of the horizontal support member for selectively supporting and manipulating a nozzle segment.

Abstract: A method for inspecting a turbine nozzle segment includes positioning the turbine nozzle segment on a base of a tool, with the outer forward face and the inner forward face of the turbine nozzle segment contacting a surface of the base. The outer wall is positioned between a first pedestal outer stand and a second pedestal outer stand of the tool, and the inner wall is positioned between a first pedestal inner stand and a second pedestal inner stand of the tool. At least one of a position, a depth and a width of a seal slot formed in a side edge of the outer wall and/or the inner wall is measured. At least one axial dimension of the turbine nozzle segment and at least one radial dimension of the turbine nozzle segment are measured.

Abstract: A tool for measuring seal slot position includes a tool shaft having a longitudinal axis, a pin eccentrically disposed at one end of the tool shaft relative to the longitudinal axis, and a disk member disposed at an opposite end of the tool shaft that facilitates rotation of the tool shaft and pin in the seal slot. The tool provides for increased accuracy in measuring seal slot position such as turbine nozzle seal slot position.

Abstract: Disclosed herein is a method for removing material from a turbine wheel dovetail slot. A tool is applied to a turbine wheel cooling slot. Material is removed from a selected portion of the cooling slot with the tool. And, stress concentrations are reduced within the slot through the removal of material.
