The invention relates to aircraft that can move near the surface of the liquid, as well as for vessels with dynamic support. Offer those who Aerohydrodynamics layout ekranoplans are performed on a "flying wing" or aircraft. In the scheme of "flying wing", which is based on the ekranoplan, the casing is in the form of a wing of small aspect ratio, the sides of which are placed end washer (longitudinal buoyancy).

Known ekranoplane of the "flying wing" type, characterized by the fact that in the plane perpendicular to the median plane of the apparatus, the support wing is curved, with variable curvature form. The curvature has both incoming and outgoing edges of the wing, in General, it is given an arched shape. On-Board playchest GeV fixed underwater wings, as the propulsion apparatus is provided for the propeller.

The curvature of the wing described GeV complicates the design and increases its mass compared to the "flat" wing. Install water-stationary underwater wings makes risky its passage through the shallow water and eliminates approach to non-equipped shore. The disadvantages should also include the use of the apparatus of the propellers, which are a source of strong noise.

The closest to the invention by the combination of essential features is a Japanese wig-CAS-3 (see[1] page 102). He made rimowa edge which is perpendicular to the median plane GeV, wing apparatus has a continuous and constructive angle of attack across the span (width), i.e., the angle between the principal plane of the apparatus and the chord of the wing.

The disadvantage of this wig with a "flat" wing is that it has for this reason reduced performance, but rather poor germination on a wave.

The technical result, which is aimed invention is to improve the navigability and to increase the efficiency of the propulsion system (engine-propulsion-unit) in different operating modes. Also the objective of ensuring the capability approach GeV to non-equipped shore.

The wig of the "flying wing", containing propellers and end washers-floats installed on the wing, aft edge which is perpendicular to the median plane of the wig, at the bottom of the aft end of each end plate-floats hinged swivel wall, forming a transverse step, which is placed between the drive shaft of the propeller located behind the aft edges of the rotary wall and made superantivirus with Castignani from end plate-floats to the median plane GeV, which is equipped with a lifting and lowering the wings, mounted on the bow of each of the floats.

Partially submerged supercavities propellers in combination with rotating walls form a single adjustable complex, whose efficiency at varying speeds GeV can be increased by changing the height position of the rotary sleeve. Performing carrier wing with variable design angle of attack in his swing can improve germination GeV waves and increase created by the wing lift force. Installation lifting and lowering of underwater wings of the nose makes it possible approach GeV to non-equipped shore and simplifies its production on the bench for inspection and repair.

In Fig. 1 presents a view of the water-side, with the clipping planes "a" and "b-b" in the main mode of motion (full stroke) of Fig. 2 GeV from above; Fig. 3 views of the water from the bottom of Fig. 4 a front view, with the clipping planes a-a and b-b of Fig. 5 section a-a in Fig. 1, lowered, turning the walls before the screws; Fig. 6 section a-a in Fig. 1 (with break), when raised walls before turning screws; Fig. 7 is a diagram Opredelenie includes washer-floats 1, connected by a lifting wing 2. On the wing 2 in the middle part of his scope posted by add-3 in the form of a cigar-shaped body. In the aft end of the wing 2 is provided with flaps 4, and on the superstructure 3 is the wheel 5.

In the forward end of each washer-float 1 fixed lifting and lowering the wing 6, and on the bottom aft end of each washer-float 1 hinged edge of the rotary wall 7. The actuator wall 7 is provided with hydraulic cylinders 8.

One of the distinguishing features of wig is the equipment it superantivirus partially submerged propellers 9, located at the aft edges relative to the wall 7. Propeller shaft connecting the screw 9 with a drive motor ( not shown conventionally), is retained by the bracket 10, is rigidly fixed on the bottom of the washer-float 1. The latter is a well-streamlined body, which keeled in the forward part of the bottom becomes flat in the stern, on the site fixing the walls 7.

In operational conditions of propulsion complex GeV will operate in current mode (full speed) and transient (acceleration). In addition to changing the frequency of verse acceleration GeV swivel wall 7 by hydraulic cylinders 8 are pressed against the bottom of the washers-floats 1, when the screws 9 are full immersion in water. Full immersion screws 9 into the water in the process of acceleration of GeV allows to increase the strength of a developing emphasis.

After the wig on "sugarboy "mode of motion swivel wall 7 by hydraulic cylinders 8 are discharged from the bottom of the washers-floats 1, forming a gradually increasing step. When approaching full speed rotary wall 7 are set in position, which corresponds to an estimated dip of screws 9, i.e., the position when the hub of the screw just touches the free surface of the water.

Full stroke GeV swivel wall 7, glissiere on the surface of the water will also create a lifting force and stabilize the fit of the wig. To reduce friction swivel wall 7 of the water it is easy to provide "air lubrication".

The ability of the GeV approach to non-equipped shore is important, especially in river conditions. Approach to non-equipped shore offer GeV preceded by the rotation of underwater wings from the lower (working) in the upper (off) position. After departing daily from the shore underwater wings down. After the rise it to slip for repair or inspection.

The ekranoplane of the "flying wing", containing propellers and end washers-floats installed on the wing, aft edge which is perpendicular to the median plane of the ground effect vehicle, characterized in that on the bottom aft end of each end plate-floats hinged swivel wall, forming a transverse step, which is placed between the drive shaft of the propeller located behind the aft edges of the rotating wall, and made supercavities with partial immersion, while the angle between the chord of the wing and the main plane of the wig increases in the direction from the end plate-floats to the median plane GeV, which is equipped with a lifting and lowering underwater wings, mounted on the bow of each of the floats.
