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 screw propulsion vehicle (SU 751700 A1, CL B62D 57/00, publ. 30.07.1980)containing two pillars between which the hinge is installed coupled with a drive rotation shaft having at its ends smooth head, United spiral blade, with one of the heads mounted on the shaft and movably provided with a power drive axial movement, screw the blade with their ends attached to the heads of the hinge, and between the turns of the blade is installed pneumonia connected to a source of variable pressure working environment. A disadvantage of the known device is the design complexity and limited technological capabilities when using the device for movement on the water and under the water. 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 in that the thruster cone made in the form of a hollow conical helical shirts, smarter the bathroom around the perimeter of the front side of the transport device with the possibility of rotation around the body of the transport device, and made of strips of convex curved shape made on the lateral edges of the bands curves of the second degree of curvature with different widths of the bands with the increase in the length of the tapered screw-shirts from the inlet to the outlet, folded in a vertical plane in the longitudinal direction and curved in a spiral lines in the transverse direction on the mandrel in the form of a paraboloid of revolution with education on the perimeter of the outside screw shirts spiral lines and spiral curved surfaces concave shape relative to the symmetry axis of the screw-shirts with the centers of curvature of the outside coil of the shirt. According to the patent and technical literature not found a technical solution similar to the declare that you can judge of inventive step of the proposed thruster cone. The novelty is due to the fact that the mover along the perimeter equipped with multiple curved helical surfaces in the form of a helical channels that give transport device longitudinal movement with great speed defined by pitch spiral surfaces, for example, at step helical surface of the conical helical shirts, equal to 100 meters over one of its turnover, the transport device can move 100 meters, at a speed of 90 rpm, the speed of transport in which trojstva can reach a speed of 540 km/h. The novelty lies in the fact that due to the outer spiral surfaces of double curvature resisting movement of the transport device is reduced, it increases the speed and reduces noise, which in combination with the specified geometric elements of helical cone-shirt improves its characteristics. Novelty also lies in the fact that the implementation of the propulsion conical shape provides a vehicle acoustics and reduce drag. The novelty of the invention lies in the fact that the screw-shirt along the entire length has a variable smooth not only transverse but also smooth longitudinal cross-section that reduces resistance during movement of the transport device and its quiet. Novelty is seen that the screwing of the screw shirts made multiple channels curvilinear shape, which increases traction power and propulsion, increases the speed and reduces noise. Novelty also lies in the fact that the perimeter of the screw shirts formed helical surface with a variable width of a concave curved shape along its length, which reduces the resistance to movement of the transport device. Novelty is also due to the fact that the step spiral lines around the perimeter of changes linevideo shirts from the inlet to the outlet, that changes the resistance of the transport device. Novelty is also due to the fact that the mover along the perimeter made of folded in a vertical plane and sequentially interconnected along the length of the screw-shirt strips convex curved shape, 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 screw-shirt spiral lines and spiral surfaces concave shape with the centers of curvature of the outside screw 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.

Hollow conical helical shirt 1 (figure 1, figure 2) is made of strips, for example, 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 with the side edges 15 and 16 of the convex curved shape (figure 3), made with different widths of strips, for example, in figure 3, the strip 11 is made of a width of 17 from the outlet 3 of the conical screw 1 shirt, which is greater than the width 18 in the inlet 2 tapered screw 1 shirt. Strip 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 with the side edges 15 and 16 of the convex curved shape is described by curves of the second degree of curvature with different widths of strips 17 and 18, with the increase in the width of the bands along the length of the tapered screw-shirts 1 from the inlet 2 to the outlet 3, twisted along a helical line in the longitudinal direction (figure 5) relative to the longitudinal axis O1-O1and bent along a helical line in the transverse direction on the mandrel in the form of a paraboloid of revolution 19 (figure 5, 6) with the formation around the perimeter of the conical screw screw 1 shirt lines 20 (figure 1, figure 2) and screw surfaces 4 a concave shape in view of the helical grooves 21 with the centers of curvature of the outside of the hollow conical screw 1 shirt. Strip 5, 6, 7, 8, 9, 10, 11, 12, 13, 14 after the bend is removed from the mandrel 19 (figure 5, 6) and are connected to each other side by sides (edges 15 and 16) with known methods, for example by welding, with the formation around the perimeter of the hollow conical helical shirts 1 screw lines 20 and screw grooves - spiral surfaces 21, variable, increasing the length of the hollow conical helical shirt step 1 S1. One of the helical lines 22-23 shown in figure 1 and figure 2 thickened line. Transport device, such as a submarine (Fig.7, Fig), includes a housing 24 with two rows of missile shafts 25, logging 26, the steering complex 27 and 28, and the mover 29. The propeller 29 is mounted, for example, along the perimeter of the front side 24 of the transport device without the possibility of axial movement relative to the housing 24 and is provided with devices to give propulsion 29 rotation around the body 24 (not shown). Moving the transport device, such as a submarine, is carried out during rotation of the propeller 29, that the rotation is screwed into the layers of water and imparts longitudinal movement to the body of the transport device, such as a submarine, with the speed determined by the frequency of rotation of the conical screw 1 shirt. The housing 24 of the transport device, such as a submarine, the motion cochranae is your position with the tail complexes 27 and 28 and felling 26. Technical appraisal and economic benefits arise due to the performance of the thruster cone in the form of a hollow conical helical shirts, mounted on the perimeter of the front part of the body of the transport device and create on its outer surface unidirectional bevel helical lines and spiral surfaces in the form of channels curvilinear forms that not only are screwed into the layers of water, but also provide, at the same time, the movement of the transport device in the longitudinal direction. The thruster cone made in the form of a hollow conical helical shirts, mounted on the perimeter of the front part of the body of the transport device with the possibility of rotation around the body of the transport device, and made of strips of convex curved shape made on the lateral edges of the bands curves of the second degree of curvature with different widths of the bands with the increase in the length of the tapered screw-shirts from the inlet to the outlet, folded in a vertical plane in the longitudinal direction and curved in a spiral lines in the transverse direction on the mandrel in the form of a paraboloid of revolution with education on the perimeter of the outside screw shirts spiral lines and spiral curved surfaces concave shape relative to the symmetry axis of the screw-shirts center and the curvature of the outside screw-shirts.
