The apparatus of the air cushion includes two related and located one after the other wing, the first wing 1 (Fig.1...12), the second wing 2. Wings 1, 2 made for example from sheet aluminum alloy D16 thickness of 1.5 mm, the Apparatus also includes a motor 3, disk 4, the screw propeller 5. The fuselage 6 is connected to the front beam 7, the average beam 8 posted by motor 3 with generator 9, is located further back beam 10, which placed second wing 2 and a two-wheeled chassis 11. The fuselage 6 made, for example of plastic. The first wing 1 is connected to the front beam 7 and is provided with a two-wheeled chassis 11. Each wheel 12 wheeled chassis 11 is provided with a disk 4, the axis 13, a motor 14 with a screw propeller 5. Wings 1, 2 and beams 7, 8, and 10 were made telescopically extendable to control in flight, for example by means of a hydraulic drive (not shown).

Beams 7, 8, 10 and the wings 1, 2 is made in the form of a pipe 15. At the bottom, and also on the location of the screw propeller 5 of the beam provided by the window 16 to create an air cushion. Right front fender 17, right rear fender 18, left front fender 19, left rear fender 20 is extended and retracted independently of each other. When fully extended/retracted wings 1, 2 and beams 7, 8, 10 engine 3 generator 9 is displayed at the center of mass 21 (Fig.3, 4) and the geometric center of the apparatus 22, and the center of mass 21 and the geometric center 22 of the apparatus are the same. When extended/retracted, for example, right front, right rear wing center of mass 23 (Fig.11) and the geometric center 24 do not match. Engine 3 generator 9 are the most massive parts of the apparatus, the shift of the center of mass 23 is insignificant when changing the dimensions of the apparatus, while the center of mass 23 will be in a different location relative to the modified geometry (geometric center 24 of the unit and the wings and/or a beam change position at a certain angle relative to the screen (earth, water) that provides controllability of the apparatus. Under the geometric center 22, 24 (Fig.3, 4, 9...12) is the intersection of the diagonals 25 conditional rectangle 26, the sides of which correspond to the dimensions of the device.

The operation of the device.

Turns on the engine 3 (Fig.1...12) with generator 9, the electric motor 14 with screw propulsion device 5 starts to rotate, the wheel 12 with the disk 15 rotates in the opposite direction with respect to the screw propeller 5 in the form of blades, due to torque reaction. The apparatus moves along the ground. For movement in flight, the wings 1, 2 and beams 7, 8, 10 are telescopically extended. The revolutions of screw propulsion 5 increases, the speed of the devices is increased, at the initial stage, the device maintains contact with the ground, while the air flow and the air flow with screw propellers 5 each wheel 12 to create an air cushion under the beam 7, 8, 10, and the wings 1, 2 create a lifting force due to the screen effect. Control in flight is achieved by extending or retracting the telescopic wing 1, 2 and/or telescopic beams 7, 8, 10, with the center of mass 23 against the new overall size (geometric center 24 will be in a different place. Since the engine 3 generator 9 are the most massive parts of the apparatus, the shift of the center of mass 23 is negligible compared with the change in dimensions (the geometric center 24 of the unit. For example, when flying in a straight both wings 1, 2 fully extended, to set the height of the front beam 7 (Fig.9) fully extended, the rear beam 10 is advanced partially, with the center of mass 23 will be in the rear relative to the modified geometry (geometric center 24 of the unit and the wings 1, 2 are arranged at a certain angle of attack relative to the screen (earth, water). For landing, the front beam 7 (Fig.10) partially extended, the rear beam 10 is fully extended, the center of mass 23 will be in the front part relative to the modified geometry (geometric center 24 of the unit, and the wings 1, 2 are p is on a different angle of attack relative to the screen (earth, water). When turning in flight, for example to the right, the right wings 17, 18 (Fig.11) are drawn, the center of mass 23 will be at the right side relative to the modified geometry (geometric center 24) of the device, the device tilts to the right, air flow, turn the machine to the right. When turning left, the left wings 19, 20 (Fig.12) are drawn, the center of mass 23 will be at the left side relative to the modified geometry (geometric center 24) of the device, the device tilts to the left, the air flows turn the machine to the left.

Unlike the prototype of the proposed technical solution design is simplified due to the telescopic extension and retraction by means of the hydraulic drive.

Unlike the prototype of the proposed technical solution, the management apparatus in flight simplified due to changes in overall (geometric) size of the apparatus, while the center of mass in relation to the new overall size (geometric center) will be in a different place, because the engine 3 (Fig.1...12) with generator 9 are the most massive parts of the apparatus, the shift of the center of mass is negligible compared with the change in dimensions (geometric center) of the device.
