FIELD: machine building.
SUBSTANCE: invention relates to transport machine building, namely to floating conveyors, and can be used in development of special hydrodynamic devices improving water transport properties of conveyors. Vane water-propellant propulsor comprises housing and blades mounted thereon. Blades of the wheel can extend in radial direction under centrifugal force at preset number of wheel turns and return to initial position under action of elastic elements.
EFFECT: higher thrust of propulsors and higher speed of floating vehicle when moving in water.
