The invention relates to the field of modeling aircraft, mainly 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, moulded from the ends of the elongated body in the form of a cylinder, attached sideways to the end of the wing, an elongated body is provided with a radially fixed blades having a variable height, increasing in the direction of the oncoming airflow. The oblong blades on the television set along a helical line. Elongated body has a cavity with a gas medium is lighter than air.

1 shows an aircraft with "eddy cords" at the end of the wings; figure 2 is attached sideways to the end of the wing elongated body provided with a radially fixed blades mounted along a helical line; figure 3 is a view As in figure 2.

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 and 3) moulded with the ends of the elongated body 9 in the form of a cylinder, provided with a radially fixed blades 10 mounted on screw lines 11. Number of blades - one and more. Axis O passing through the center of the elongated body parallel to the axis F, passing along the fuselage of the aircraft. The blades have a variable height, increasing in the direction of the oncoming airflow. An elongated body may have a sealed cavity 12 with gas medium is lighter than air.

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 is. Light resistant to atmospheric corrosion material (plastics, titanium alloys, aluminum) is made oblong body 9 mounted on a screw line 11 blades 10 having a variable height, smooth surfaces, rounded edges. An elongated body made solid or hollow. The cavity 12 is filled with gas lighter than air (coal gas, hydrogen, helium). Made oblong body with blades attached (glued, you solder, weld) side to the end part 8 of the wing so that the axis F and O are parallel.

In flight conditions of the 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. Education "vortex cord" is limited. The presence in the sealed cavity of the oblong body of gas is lighter than air partly counterbalanced the weight of the attached blades.

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 repairs blades PA elongated handle body washing liquid.

The invention limits the formation of the end part of the wings of the flying apparatus is ATA vortex cord".
