On each of propeller levels of ship starting from water line and lower there are two hollow floats. The floats serves as stators for spirals-rotors matched to them. The spirals have stand-alone drive for rotors of corresponding level. |

Invention relates to converters of engine or other energy source work into that driving transport facilities. Screw propulsor comprises housing composed of hollow cylindrical multistart helical jacket. Said jacket is arranged along the vehicle body edges to revolve thereabout. Said housing represents a multistart helical surface arranged along its edges with helical grooves inside and outside at 5 to 45 degrees to jacket lengthwise axis and shaped to birecurvate recesses. Centers of curvature of said recesses are located inside and outside jacket cross-section. Jacket is composed of equal-width one or more tapes coiled in helical turns interconnected by lengthwise edges. Said tapes are bent in zigzag manner along flexure lines arranged at angle to lengthwise edges. Said tapes form, along outer and inner surfaces, wavy helical surfaces shaped to curved recesses directed to one side at 5 to 45 degrees to jacket lengthwise axis. Said recesses may differ in both shape and size. Distance between flexure lines equal the sum of lengths of perimeters of geometrical figures of inner and outer surface recesses. |

Mobile robot of magnetic interaction Invention relates to robot with magnetic interaction. Proposed robot comprises frame 10 with wheels to run on support surface with high magnetic conductivity and one permanent magnet 30 to interact with said surface for adhesion between robot and said surface. Magnet 30 is arranged to slide on said support surface. Magnet 30 is fitted in holder 32 free swinging to keep magnet pole at minimum distance from said support surface whereat every support 32 can swing on wheel shaft. |

Invention relates to ship propulsors. Screw drive consists of even number of hollow cylinders with helices at generatrix and float cylinders. Every helix has, at least, two-point articulation with appropriate hollow cylinder. Said articulation allows said helix to run around float cylinder in both directions. Float cylinder doubles as helix stator. Only helix is rotated by drive in said float cylinder-with-helix assembly. |

Self-propelled off-road vehicle Invention relates to automotive industry, particularly, to propulsors and may be used in construction of higher flotation vehicles. Proposed vehicle comprises main propulsors and extra auger-type propulsor. The latter is arranged under vehicle body, in its lengthwise axis, and controlled from driver cabin. With vehicle bottom adhered to soil, auger propulsor is used to drive the vehicle forward or backward unless stable contact of main propulsors with soil that allows to move in usual way. |

Invention relates to devices in tended for converting engine power output into driving force to move transport facility on soil, in water and under water. Drive propulsor comprises propulsor proper and housing. It represents hollow cylindrical helical jacket arranged along perimeter of transport facility to rotate there around. Strips are coiled in vertical lengthwise plane and bent in screw lines across the mandrel composed of paraboloid of revolution to make screw lines and helical curvilinear concave surfaces with center of curvature outside screw jacket. |

Invention relates to devices is intended for converting engine power output into driving force to move transport facility on soil, in water and under water. Conical propulsor represents hollow conical helical jacket mounted in perimetre of transport facility body front to remove there around and made up of curved convex strips. Strip side edges represent curves of 2nd-order curvature of width varying over aforesaid jacket length from inlet to outlet. Strips are coiled in vertical lengthwise plane and bent in screw lines across the mandrel composed of paraboloid of revolution to make screw lines and helical curvilinear concave surfaces with center of curvature outside screw jacket. |
