The invention relates to the field of modeling aircraft, mainly models of civil aircraft and transport aircraft.

Known wing of the aircraft, containing the frame, casing, elements of the deflection of the air flow flowing upper and lower aerodynamic surfaces, moulded from the ends of the elongated body attached sideways to the end of the wing [1].

During flight of the aircraft due to the differential pressure under the wing and on the wing of the air in the front part of the wing tends to move upwards. The formation of eddies, which are blown off the counter flow of air. Sliding off the wing turbulence go back as long eddy cord".

The task of the invention consists in the destruction of the "vortex cord".

The technical solution of the task is achieved by the fact that the wing of the aircraft, containing the frame, casing, elements of the deflection of the air flow flowing upper and lower aerodynamic surfaces attached sideways to the end of the wing pointed at the ends of the oblong body having a discharge nozzle, wherein the elongated body has a shape of a polyhedron with vertically attached to faces of the blades of a variable height, increasing in the direction of the magic cube MOV is I the oncoming airflow. The blade edges are inclined relative to the axial line of the oblong body. The discharge nozzle is located at the end of the elongated body along its axial line.

1 shows an aircraft with "eddy cords" at the end of the wings; figure 2 is attached sideways to the front-end part of the wing is moulded with the ends of the elongated body, equipped with blades; figure 3 shows an embodiment of the pointed ends of the oblong body.

Attached to the fuselage 1 of the aircraft (figure 1) wings 2 contain the frame 3, a casing 4, items 5 deflection of the air stream, flowing top 6 and bottom 7 of the aerodynamic surface. The end portion 8 of each wing is attached (figure 2) moulded with the ends of the elongated body 9 in the form of a regular polyhedron with vertically attached to faces of the blades 10 of a variable height, increasing in the direction of the oncoming airflow. The blade is smooth, have rounded edges. On the sides of the oblong body of the blades are inclined relative to the axis O passing through its center (figure 2), and the axis About parallel to the axis F, passing along the fuselage. The angle of the blades relative to the axis Of depends on the flight speed of the aircraft. The higher the speed, the smaller the angle of inclination. Cross fight the AI elongated body can have the shape of a triangle, square, Pentagon, hexagon, etc. Pointed ends 11 and 12, respectively, the nose and tail, have the shape of a regular pyramid (triangular, square, pentagonal, hexagonal, etc.) or pyramids with rounded apex (Fig 3). The number of blades on the elongated body is equal to the number of faces minus one. An elongated body may be solid or have a cavity 13. In the wall 14 of the polyhedron attached sideways (dashed line in figure 2 and 3) to the end of the wing, made at least one production hole 15. The fore end of the elongated body can be equipped with an antenna 16 of the radio communicating cable 17 with the radio station of the aircraft. The tail end of the elongated body may be equipped with a pressure nozzle 18 attached to the tubing 19 of the feed gas environment. The antenna and the discharge nozzle are located along the axis O.

Make model, a prototype of the aircraft (figure 1) with the fuselage 1 and wings 2 having a frame 3, a casing 4, items 5 deflection of the air stream, flowing top 6 and bottom 7 of the aerodynamic surface. Then made, for example, using a thin-walled section five-sided coarse, elongated body 9 with pointed nose 11 and the tail 12 ends, having the shape of a regular five-sided pyramids. The four faces of p is Dolgopyatova body attached (glued, you solder, weld) of the blade 10, having them vertically relative to faces and inclined with respect to the axis O. Oblong body with blades made of light resistant to atmospheric corrosion material (plastics, titanium alloys, aluminum). Made elongated body attached sideways (fifth line) to end of part 8 of the wing so that the axis F and O are parallel (figure 1 and 2). In the case of manufacturing an elongated body with pointed ends having rounded peaks (figure 3), along the axis O in the forward end of the fixed antenna 16 of the radio, and in the tail end of the set discharge nozzle 18. In the wall 14 of the elongated body having a cavity 13, perform technological holes 15 for the strip, respectively, of the cable 17 and line 19.

In terms of flight model, prototype aircraft air flows occurring at the end of each wing and looking to switch from the bottom up, confront twisted in the opposite direction air flow formed by the blades on the elongated body. Flowing from the discharge nozzle jet of gas is an additional source of destruction "vortex cord". In bad conditions, the front-end part of the wings of the aircraft to protect the case from sediment snow and ice formation. In the implementation of preventive or REM is ntih works each elongated body, situated at the end of the wings handle the scrubbing liquid.

The invention limits the formation of "vortex cord" at the end of the wings.
