Closest to the proposed invention is the mover, the Japan patent No. 50-12672, CL VV 11/10, publ. 13.05.1975 containing outer and inner housings, the entrance to the cavity, one of which is blocked by a gate. A disadvantage of the known device is limited technological capabilities when using the device for movement on land and complexity of design. Technical solution to the problem is the expansion of technological capabilities due to the possibility of using the device for movement on land and under water, as well as simplifying the design. A technical solution is achieved in that the propulsion ramjet made in the form of a hollow cylindrical multiple-screw-shirt from one or more strips of the same width with the formation on its outer surface directed to one side under an angle of 5-45° to the longitudinal axis of the screw lines and spiral surfaces of the polygonal shape in the form of various geometric shapes with four or more sides, with these geometric shapes can be different not only in shape but also in size, with multiple hollow cylindrical coil jacket mounted around the perimeter of the body of the transport device with the possibility of rotation around its longitudinal axis and the building is as a transportation device. According to the patent and technical literature technical solutions are not found, similarly declared that allows to judge about the inventive step of the proposed propulsion flow. The novelty is due to the fact that due to the outer spiral surfaces of the polygonal shape around the perimeter of a rotating helical shirts not only decreases the flow resistance, but also expanding 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.

Novelty also lies in the fact that the placement of the mover along the perimeter of the transport device and run it from one or more rolled into cylindrical coils connected to each other along the longitudinal edges of the ribbons of the same width, bent with the formation on the outer surface directed in the same direction under an angle of 5-45° to the longitudinal axis of the hollow cylindrical multiple-screw-shirt spiral surfaces that are on the perimeter of the hollow cylindrical multiple-screw-shirts can be different not only in form, but the size, provides a vehicle acoustics and reduce drag. Novelty is seen also in the fact that "screwing" helical shirts made multiple helical channels polygonal shape, which increases traction power and propulsion, increases the speed and reduces noise, enhances technological capabilities. Novelty also lies in the fact that the perimeter of the screw shirts formed helical surface with a constant width along the length, which reduces the resistance of the medium to the movement of transport is private. Novelty is also due to the fact that the step spiral lines on the perimeter of the screw-shirts from the inlet to the outlet constant, which reduces the resistance of the transport device.
