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

Known aircraft, containing the fuselage with attached wings, with elements of the deflection of the air flow flowing upper and lower aerodynamic surfaces, at least one engine, tail, chassis [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 objective of the invention is to limit education at the end of the wing vortical cord".

The technical solution of the task is achieved by the fact that in an aircraft containing the fuselage with attached wings, with elements of the deflection of the air flow flowing upper and lower aerodynamic surfaces, tail, at least one engine, chassis, mechanical parts of each wing is attached by a perforated plate located parallel to the vertical plane running along the fuselage. Mesh plate has the shape of a t is apachi and the size of the openings increasing as the distance from the upper and lower aerodynamic surfaces.

1 shows an aircraft with "eddy cords" at the end of the wings; figure 2 shows a mesh plate having a trapezoid shape, fixed to the end portion of the wing; figure 3 shows a mesh plate (the dashed line shows the contour of the end face of the wing) with a convex edge.

Aircraft (figure 1) contains a fuselage 1 with attached wings 2, with the elements 3 of the deviation of the air flow flowing upper 4 and lower 5 aerodynamic surfaces, at least one engine (jet, propeller, propeller planes or the other, not shown), the tail Assembly 6, the chassis (not shown). The end portion 7 of each wing (figure 2) is provided with a rigid mesh plate 8 that is parallel to the vertical plane Q passing along the fuselage at its center (figure 1). Mesh plate made of lightweight resistant to atmospheric corrosion material, has a trapezoid shape and size of the holes 9for the passage of air, increasing as the distance from the upper and lower aerodynamic surfaces. Mesh plate may have holes for the passage of air of the same size. The holes in the mesh plate can be round, square, oval or other. Edge is echtay plate along the perimeter of the rounded. The edge of the mesh plate from the upper aerodynamic surface may be in the form of convexity (figure 3). The edges of the holes for the passage of air in the mesh plate (in the direction of air flow at the face of the wing from the bottom up) rounded. For fasteners (such as screws) to the frame in the front-end part of the wing mesh plate can be made of the hole 10. For laying electric cable, for example, located at the end of the wing (near the end) signal to a light source (not shown)in mesh plate may be made of at least one production bore 11.

Make model aircraft, containing the fuselage 1 with attached wings 2, with the elements 3 of the deviation of the air flow flowing upper 4 and lower 5 aerodynamic surfaces, at least one motor (not shown), the tail Assembly 6, the chassis (not shown). To the frame of each wing end part 7 (figure 2) is attached, for example by screws, mesh plate 8, using the holes 10. Irrespective of the size and position of the wings relative to the fuselage, a mesh plate having a trapezoid shape, is attached to the end of the wing or directly to an end face parallel to the plane Q (Fig 1). In the presence of the signal light sources located at the end of the wings, through holes 11 (Fig 3) in the mesh plate is passed an electrical cable (not shown).

In flight conditions of the aircraft air flows that occur at the end of each wing, are striving to move from the bottom up, however, dissipate mesh plate in small streams, passing through numerous holes 10 are the same or different sizes. This formed the "vortex cord partially eroded, it becomes unstable and disintegrates quickly.

In the implementation of preventive orrepairs mesh plate handle washer fluid.
