  • Turbine thrust control system
    Patent number: 9341073
    Abstract: Systems and programs for controlling thrust in a turbine by adjusting the clearance between a packing seal and a rotating component are disclosed. In one embodiment, a system includes a controller configured to move a packing seal to a selected clearance position in response to a thrust pressure exceeding a target pressure, and a sensor coupled to the controller and configured to detect the thrust pressure.
