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 [1]. During the flightaircraft due to the differential pressure under the wing and onthe 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 flowair. Sliding off the wing turbulence go backas long eddy cord".

The objective of the invention is to limit the formation ofat the end of the wing vortical cord".

Technical result : taskis achieved by the fact that the wing of the aircraft, containing the frame is,lining,the elements of the deflection of the air stream, flowing top andthe lower aerodynamic surface, equipped with a mesh plate,located at its end part along the bottom dragsurface. The mesh plate is made retractable from the slot in the front-end part. Mesh plate has a triangularthe shape and size of theholes, increasing as their removal is from the front-end part.

Attached to the fuselage 1 of the aircraft (figure 1) wing 2 has a frame 3, a casing 4, items 5 deflection of the air flow (ailerons, flaps, and other), going around the top 6 and bottom 7 of the aerodynamic surface. End part 8 of the wing (figure 2 and 3) is provided with a rigid mesh plate 9, still located along the lower aerodynamic surface. Mesh plate made of light-resistantatmospheric corrosion material, has a triangular shape with rounded corners, smooth surfaces and the size of the holes 10, increasing as it is removed from the end part of the wing. The holes in the mesh plate can be round, square, oval or other. The edges of the holes from the lower aerodynamic surface rounded. Mesh plate can be made retractable from slot 11 front part of the wing (figure 4).

In flight conditions of the aircraft have attached to the fuselage 1 wing 2 having Karkas, the casing 4, items 5 deflection of the air stream, flowing top 6 and bottom 7 of the aerodynamic surface, the air flows occurring at the end of part 8, strive to go from the bottom up, however, dissipate mesh plate 9 in small streams, passing through numerous holes 10. This formed the "vortex cord partially eroded, it becomes unstable and disintegrates quickly. In bad conditions, mesh plate (with holes of the same or different size) retracts into the front-end part of the wing through the slot 11, for example, to protect against sediment snow and ice formation. In the implementation of preventive or repair work mesh plate handle washer fluid.
