metadata.value: The paper considers the development of numerical modeling of the flow around the variable
  pitch propeller (VPP) and its subsequent optimization without the influence of ship hull. In
  the first step of the work, a three-dimensional computational grid has been obtained, and
  a routine work in Star-CCM+ has been automated. In the second step the technology of
  the optimization VPP with strictly defined constraints has been developed. As a result, the
  satisfactory increase in the efficiency of the propeller has been obtained. The analysis of the
  results has been carried out and the comparison graphs of experimental data with numerical
  calculation for the main hydrodynamic characteristics have been constructed. In addition,
  the influence of the globalization degree of the surrogate optimization algorithm on the
  quality and the speed of finding a solution within the task definition has been investigated.
  The results of the work have been obtained in Krilov state research institute (KSRI) and are
  being used in the applied tasks in shipbuilding.
