FIELD: transport.

SUBSTANCE: proposed vehicle comprises body, head, propulsor and steering complex. Hollow cylindrical screw jacket is arranged around the periphery of the body to spin there about and around its axis. Said jacket has outer laps as screw blades over the entire length of screw jacket. It is composed by three or more rectangular equal-width equal-length strips concaved or convexed relative to screw jacket rotational axis. Said strips are coiled in vertical plane in lengthwise direction and flexed in screw lines across cylindrical mandrel. Or, said screw jacket can be composed by three or more screw strips, curvilinear of various order and degree of curvature at centres located outside or inside screw jacket cross-section. Said strips are interconnected to make laps as screw blades over the entire length of screw jacket, screw lines and screw curvilinear surfaces as helical grooves concaved or convexed relative to screw jacket rotational axis with curvature centres located outside or inside screw jacket cross-section.

EFFECT: enhanced operating performances.
