Abstract

PURPOSE: To prevent exerting of the influence of vortexes produced in the proximity of a propeller shaft, by a method wherein guide vanes, being positioned separately from a propeller blade, are placed at a root part of the propeller blade.
CONSTITUTION: Guide vanes B3 are placed at intervals at a root part of a propeller blade A, being positoned ahead of the rotation direction of the propeller blade A. The guide vanes B3 function as a type of a vortex generator, and vortexes, produced by the vanes, perform a role to erase the vortexes produced around a propller shaft. The displacement of the vane by, for example, C>0.5tMAX prevents contact of the vortexes, generated by the guide vanes B3, with the surface of te propeller blade A but causes skimming of the vortex along the blade surface.
