Does this model ship is as follows.

After starting the main 11 and March 15 of engines included the clutch 10 of the main engine. The rotating torque from the main motor 11 through the clutch 10 via a cardan shaft 5 through the gears 7 and the differential longitudinal 8 and 9 cross slope, the gear 6 is transmitted to the propulsion of the vertical rise of 4 right and left sides. The rotors 16 come into rotation and create a lifting force F, which balances the weight force of the vessel P and lifts it above the water surface (Fig. 25). The emergence of lifting with the crystals on the rotors, propellers, vertical lifting happens in three ways. First, when the rotor 16, the air inlets 24 trap air and send it through channels 23 for all three end surface of the rotor, creating them rotating air flow, exhaust sideways under a thin disks 19, and in the upper part of the rotor goes up in the form of a rotating vortex (Fig. 23). Rotating streams of air to create these surfaces forces rarefaction F10F11F13(Fig. 24), greatly reducing the pressure of the atmospheric air on these surfaces. Secondly, the air inlet 29 serves the air in the intake-exhaust ports 28 inside both cavities 25. The incoming air flow circulate, as shown in Fig. 23 creating these cavities high pressure. Thin disks 19 prevent the air flow from the cavity 25 on the end surface of the rotor, separating them. In Fig. 22 shows that the opposite inclined surface of the same size l=l1,l2=l3,l4=l5l6=l7and square. The force of air pressure on the equal and mutually balance each other - F=F1, F2=F3F4=F5F6=F7(Fig.24). Horizontal surface 26 is also equal in size and in area l8=l9and S=S1but the forces F8and F9nothing is balanced and create a lifting force, adding at the same time.

Third, lifting the power is created on the lower end surface of the third part of the rotor 16. When the rotor moving boundary layer air flows inward radial trapezoidal channels 30 and produces pressure on the bottom and walls of these channels. The opposite radial surfaces of these channels equal in size l=l1and square. The forces acting on them, balance each other and equal in magnitude F=F1. Small and big walls of the channel are not equal among themselves, and the forces acting on them are different, but they do not create a lifting force. Forces F2acting on the bottom of each radial trapezoidal channel 30, no offset, fold and create a lifting force (Fig.13, 14). The rotation of the rotor 16 having a force F8F9F10F11F12F13creating a lift force (Fig.24). Similarly occurs lifting force on other rotors, propellers, vertical lifting. The above power propulsion vertical counterbalance the weight of the vessel P and raise it above the surface of the water. The magnitude of the lifting force is controlled by changing the rotation speed of the main motor 11. Further included clutch 10 and the main engine 15 through the drive shaft 5, the gear 7 causes the rotation of the propellers with controllable pitch 13 and the ship begins to move forward. At the steady state motion of the force that moves the ship with a speed υ, ur novasuede strength su (Fig.25). The speed of the vessel over the surface of the water is regulated by the frequency of rotation of the shaft main engine 15. The ship management course is a foot pedal 32. By pressing the right or left pedal 32 it is rotated around the axis 33 and its lever 34 presses the left or right hydraulic valve 37. The oil from the oil tank 35 from the oil pump 36 through the piping 41 is served in one or the other cylinder chamber 38. Under the action of oil pressure rod of the hydraulic cylinder 38 is pushed into the housing or extend through the thrust levers 39 and 40 rotate in the desired direction of water and air rudders 31, providing rotation of the vessel in the desired direction (Fig.17). Management of ship's stability in space while moving over the surface of the water as follows. To make the climb, you must turn the control knob 42 in position "on". The lever 46 rotates and clicks on the front spool hydraulic valve 45. The oil from the oil tank 35 from the oil pump 36 is fed into the rear hydraulic cylinder 48. The spindle extends and brake 67 presses on the rear brake drum 66 double bevel differential longitudinal slope 8. The rotational speed of the front axial shaft 63 will increase, and the rear axial shaft will decrease (Fig.18). As a result the rotational speed of the rotors 16 front four DV the inhabitants of the vertical rise of 4 will increase, and four rear thrusters vertical lift will decrease. Lifting force at the front of the hull will increase, and in the rear part of the body will decrease. The front part of the hull will rise, and the rear will be lowered and the ship will occupy the position shown in Fig. 26. To reduce ship you the control knob 42 is turned to the position. The lever 46 rotates and clicks on the rear spool hydraulic valve 45. The oil from the oil tank 35 from the oil pump 36 will be fed into the front hydraulic cylinder 48. Brake 67 clicks on the front brake drum 66 double bevel differential longitudinal slope 8. In the rotation speed of the front four propellers, vertical lifting 4 decreases and the rotational speed four rear thrusters vertical rise of 4 will increase. Lifting force at the front of the housing 1 will decrease and the rear will increase and the ship will occupy the position shown in Fig. 27. To create a roll to starboard need the control knob 42 to rotate around its axis to the right. Semicircular sector 44 clicks on the spool of the left hydraulic valve 47. The oil from the oil tank 35 from the oil pump 36 will be fed into the right cylinder 47 and the brake 67 clicks on the right brake drum 66 double bevel differential cross slope 9. Right axial shaft 63 mind is nishit speed, and the left will increase. As a result the rotational speed of the rotor 16 of the two middle vertical propulsion lifting the left side will increase, and the frequency of rotation of the two middle vertical lift propulsion 4 starboard side will decrease. The lifting force F starboard will decrease, but the left side will increase. The hull of the vessel will rotate around the longitudinal axis to the right and will occupy the position shown in Fig. 28. To create a roll on the left side of the control knob 42 to rotate around its axis to the left. Semicircular sector clicks on the spool of the right hydraulic valve 47. The oil from the oil tank 35 from the oil pump 36 will be fed into the left hydraulic cylinder 49, the brake 67 clicks on the left brake drum 66 double bevel differential cross slope 9. Left axial shaft 63 will reduce the frequency of rotation, and the right axial shaft at the same rate will increase. The frequency of rotation of the two middle vertical lift propulsion 4 left side decreases and the rotational speed of the two middle vertical lift propulsion 4 starboard will increase. The lifting force F on the left side will decrease, but on the starboard side will increase. The hull of the vessel will rotate around the longitudinal axis and make a roll on the left side (Fig.29). After arriving at the destination, the speed of the main engine 11 is reduced, the carrying power of the propulsion of the vertical rise of 4 smooth is reduced and the vessel is lowered to the water surface. Main engine 11 is stopped. Further maneuvering on the water is propulsion horizontal movement 12 and water-air rudder 31. The vessel is back and braking in displacing mode and in flight by varying the thrust of the propulsion horizontal movement 12 by setting the propeller blades 13 in position.

FIELD: transport.

SUBSTANCE: invention relates to air-cushion ships. In compliance with proposed method, air-cushion ship is provided with two rotary rudders arranged at the thrust air duct outlet. Pilot cab is provided with two handles that can independently rotate about appropriate axis of rotation. Each said handle is connected with said rotary rudder so that turning said handle causes rudder turning. To allow joint displacement of both handles, they are articulated by link element with hinge joints on their ends. Said link element can vary the distance between said handles on applying opposite=direction forces thereto. Turning said handle in one direction turns rudders in one direction, while turning said handle in opposite directions causes turning of rudders in opposite directions.

EFFECT: simplified control of air-cushion ship.
