The invention relates to a device for converting the motor or other power sources to work, providing traffic devices, such as cars, tractors, agricultural machinery, on earth, under the earth, and can be used in and under water. Known mover in the form of a wheel gear drive axle of the vehicle, patent No. 2170863, CL VC 17/32, publ. 10.12.1999 containing a planetary transmission comprising a sun gear mounted on shafts, Stellite, located in a drive rod having a Central hole, and the root of the gear cover pinion carrier thrust washer, stop the sun gear, carrier is made with a locking groove and provided with an adjusting nut and a lock washer, and adjusting nut are made with locking grooves and placed in the Central hole of the carrier, made the screw and retaining washer are made with external and internal mustache, and the outer condition is placed in the locking groove carrier and the locking groove of the adjusting nut, except also, the cover carrier is made with ribs, pressing the lock washer to the end surface of the carrier. A disadvantage of the known device is the design complexity and limited technological capabilities when using the device is TBA for movement on the water and under the water. Closest to the proposed invention is a device SU 751700 A1, B62D 57/00, 30.07.1980, comprising a housing and a propeller. A disadvantage of the known devices are limited technological capabilities. 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. A technical solution is achieved by the passing vehicle containing the propeller and the hull, the propulsion device made in the form of a hollow cylindrical screw-shirts, mounted around the perimeter of the body of the transport device, and equipped with devices to give propulsion rotation around its own axis and the housing and made of at least one ribbon of the same width, bent on placed at an angle to the longitudinal edges of the tape to bend lines with the formation on the outer surface of the helical lines and convex in one direction with the centers of curvature of the inside of the hollow cylindrical screw-shirt spiral curved surfaces, which are on the perimeter of the cylindrical multiple-screw-shirts can be different not only in form, but the size, the distance between the fold lines is equal to the sum of the lengths of the perimeters of geometric shapes convex to one side of the curved surfaces is on the perimeter of the hollow cylindrical screw-shirt. 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 pass-propulsion. The novelty is due to the fact that the driver of the screw along the perimeter provided with multiple helical lines and convex in one direction with the centers of curvature of the inside of the hollow cylindrical screw-shirt spiral curved surfaces, which give the transport device longitudinal movement with great speed defined by pitch spiral surfaces, for example, at step screw surface screw-shirt, 50 meters, for one turnover of the transport device can move 50 meters, at a speed of 200 Rev/min transport speed of the transport device can reach 600 km/h. The novelty of the proposal is also due to the fact that the thruster is mounted on the perimeter of the body of the transport device that provides a reduction in energy costs in its movement and expanding technological capabilities. The novelty lies in the fact that due to the outer spiral curved surfaces resisting movement of the transport device is reduced, it increases the speed and reduces noise, which in combination with the specified geometrician the economic elements of helical shirt improves its characteristics, expanding technological capabilities. Novelty also lies in the fact that the placement of the mover along the perimeter of the transport device and execution of its hollow cylindrical provide multiple transport unit silent operation and reduced resistance, expanding technological capabilities. The novelty of the invention lies in the fact that the helical shirt along the entire length has a smooth cross-section that reduces resistance during movement of the transport device and its quiet. Novelty is seen also in the fact that "screwing" screw-shirt is made multiple channels curvilinear shape, which increases traction power and propulsion, increases the speed and reduces noise. Novelty is also due to the fact that the step spiral lines around the perimeter of the screw-shirts constant, which reduces the resistance of the transport device. Novelty is also due to the fact that the mover along the perimeter of the screw-shirt is made of rectangular strips, folded in a vertical plane in the longitudinal direction and curved in a spiral lines in the transverse direction with the formation along the perimeter of the helical shirts spiral lines and spiral surfaces concave shape of the centers of curvature of the outside helical shirts, that facilitates the movement of the transport device and increases the speed by reducing the resistance of the environment in which moves the transport device, improves the cavitation characteristics, provides a reduction in energy costs in its movement.
