The invention relates to the transport and for the design and construction of the wig.

Famous winged containing the fuselage top and bottom, with side plates, wings, located under the scheme biplane, vertical and horizontal tail, launch and propulsion motors, the control system, the upper wing is made by lengthening5, with the sweep of the leading edge slats and slotted flaps, the bottom wing is made with extension1,5 rectangular shape in plan, with a flat bottom surface is from the lower to the upper chord of the wing, its the starter motor is located inside the forward fuselage and made with venting channels-nozzles for directing gas jets under the lower wing and the formation of the starting air cushion (patent RU 2129501 C1, 6 60 V 1/08, 64 39/08, publ. 27.04.1999,, bull. No. 12).

However, the known ekranoplan has a low performance.

The technical result from the implementation of the described invention is to improve performance GeV by increasing its profitability, economic efficiency and operational safety.

This technical result is achieved by the fact that the wig that contains the fuselage top and bottom, with side plates, wings, located under the scheme biplane, vertical and horizontal tail, launch and propulsion motors, the control system, the upper wing is made by lengthening<5, with the sweep of the leading edge slats and slotted flaps, the bottom wing is made with extension>l,5 rectangular in plan, with a flat bottom surface with flaps, and his side of the washer is made in the form of floats-sections, and the distance vernaglia and done with venting channels-nozzles for directing gas jets under the lower wing and the formation of the starting air bags, according to the invention in the fore part of the wig is the third wing, consisting of two aerodynamic wings consoles, which have an angle of attack sweep along the front edge slats and slotted flaps, made with aerodynamic wings on the ends in the form of vertical plates, and the height of this wing relative to the center of mass GeV is less than the corresponding height of the wing, located in the rear part of the wig. The upper wing in the rear part of the wig with the angle of attack with a sweep of the leading edge, also done with aerodynamic wings on the ends in the form of vertical plates. The use of the aerodynamic wing in the nose significantly increases load-bearing properties of the wig due to both increase the overall aerodynamic component of the aerodynamic wing in the nose and tail parts of the wig, and the corresponding optimal distribution of the aerodynamic lifting force in a certain optimal proportions between the front and rear wings GeV and the resulting point of its application (this model the focus is determined from the stability condition GeV), spacialized ability GeV to semistability height and increased longitudinal stability when flying on the screen compared to the prototype, allows to reduce the landing speed, to reduce the dynamic loads on the controls, and structural force diagram of the device and thereby reduces the overall weight of the whole structure, thereby increasing the useful weight return GeV as a vehicle in comparison with the prototype, can also improve the stability and controllability, and hence to improve the safety of flight as on the screen, and transient conditions. All this allows to have a relative lengthening of the upper wing at the tail end GeV<5, the lower wing is made with extension>1,5, with a flat bottom surface of the bottom of the wing forms the goal of attack relative to the reference underlying surface, thereby further improving the anchoring of the device to the screen, his semistability height and a further increase in longitudinal stability when flying on the screen, improving flight safety in comparison with the prototype, while increasing, as indicated above, the load-bearing properties of the ground effect vehicle as the vehicle.

Thus, the use of aerodynamic wings consoles in the fore part of the wig allows gif"><5, and the lower wing display, made with angle of attack relative to the reference underlying surface, to perform a relative elongation>1,5, thereby allowing to considerably increase the weight returns GeV as a vehicle in comparison with the prototype, can improve the stability and controllability, and hence to improve the safety of the flight on the screen and in transient conditions.

The distance of the wing 2 wing 5 more chord of the wing 2.

The ekranoplan is made with a control system (not shown).

The operation of the wig is as follows.

Start GeV (like the prototype) is against the direction of the wind with a small directional angles to the wavefront of the reference surface and begins translation engines at maximum operation.

In the beginning of the movement in contact with water are floats-sidewall 7, and then with increasing speed GeV under the action of air flow and work starting podobnogo engine receiving air through its inlet 11 on the wing 5, on the upper aerodynamic wing 13 in the nose and on the wing 2 in the rear part of the wig from the air flow produces aerodynamic lift force, under the action of which the water separates from the surface of the water and continues its flight in cruise mode the th surface, consists of the aerodynamic lifting force on the forward wing 13, the aft wing 2 and the display wing 5.

The fit of the wig similar to the prototype performed on the water surface translation engines on the mode of flight of small gas when released the flaps 4 of the upper rear wing 2, released the flaps 15 of the front wing 13 and the flaps 6 of the lower wing 5. In the case of rough seas to reduce loads on the hull structures used intermittent positive pressure from the first engine speed range planning.

Engines, machines, mechanisms and equipment (not shown) are selected from serial aeronautical products and provide the specified modes of operation.

Comparing the technical and economic characteristics of the developed GeV with located in the fore part of the third wing, consisting of two aerodynamic wings consoles and biplane wing, with modern vehicles, it can be concluded that the distinctive features of the described invention together give the ekranoplan new properties and provide advantages in technical, economic and environmental aspects, namely specialsa sufficient “anchor” of the device to the screen through the bottom of the wing 5 and the wing 13, located in the fore part of the wig, their combination and interaction allow to perform the maneuver speed for safe passing through the narrow waters of the rivers, congestion, bridges, etc.,
