According to the patent and technical literature not found a technical solution similar to declare, that allows to judge about the level of invention offer screw propulsion. The novelty lies in the fact that the screw propeller contains one case, made in the form of a hollow cylindrical screw sleeve that rotates around the body of the transport device that extends the technological capabilities and simplifies manufacturing. The novelty is due to the fact that due to the outer spiral surfaces of double curvature along the perimeter of a rotating helical shirts not only decreases the hydraulic resistance, but races is yaytsa technological capabilities. Novelty also lies in the fact that the screw-shirt is made of one or more tapes, expanding technological capabilities and simplifies manufacturing.
