97. For a large main propulsion turbine, the most commonly used turbine thrust bearing is the __________.

Large main propulsion turbines utilize pivoted segmental shoe thrust bearings to manage substantial axial thrust loads. These bearings, also known as tilting-pad or Michell/Kingsbury bearings, employ pivoting shoes to distribute load and maintain a stable oil film. Other options are radial bearings unsuitable for high axial thrust or describe rotor configurations, not bearing types.
