FIELD: pumps and turbines. SUBSTANCE: rotor used in device forming fluid medium flow or converting energy of fluid medium flow is mounted for rotation relative to central axis and is provided with working surface whose directrix sets bow-shaped line of motion of fluid medium flow located around central axis of rotation of rotor. This directrix of working surface has form of logarithmic curve which corresponds to mathematical progression known as golden section or Fibonaci progression. EFFECT: reduction of wear; enhanced efficiency. 33 cl, 17 dwg
