The invention relates to the field of aviation. As you know, the wing portion of the aircraft, forming a lifting force when flying in the atmosphere. Numerous studies have shown that the shape of the wing that creates the least resistance to movement in the air flow, the shape is close to a teardrop.

Known wing aircraft according to the book "structural Design of aircraft", edition 1987, authors Essays, Ayinger, Shameli-Sargsyan, Imolation [1].

The wing design depicted in this book [1] on RES 27. str, consists of an inner supporting frame, upper and lower casings, and the profile of the wing has a tear drop shape on RIS, 23, str.

The disadvantages of this wing can be attributed to the relatively small lifting force.

The purpose of the invention is the creation of a wing of a new type, different from the wing teardrop profile, but is able to create a lifting force.

This objective is achieved in that the proposed wing is in the form of a tray, which has a variable cross-section in plan and tapers smoothly from nose to tail.

The proposed wing is illustrated in the drawings figure 1-4.

Figure 1 shows the front wing.

Figure 2 shows a view of the wing on the side.

Figure 3 shows a view of the wing from above.

Figure 4 shows the option to install the wing on the fuselage.

When the movement is of loleta on takeoff and flying his wing this construction forms a lifting force, as the speed of the air flow in smoothly tapering tray from section a-a to section b-B increases. Inside the tray, a vacuum, and the bottom of the tray is formed of a lifting force. According to equation D. Bernoulli average speed of air flow in the cross sections A-a and B-B is inversely proportional to the squares of these sections, which simplifies the calculation ability of the wing [2].

SUBSTANCE: proposed high-speed swept wing consists of center-wing section and outer-wing panel. Wing is formed as single spatial system on base of non-planar middle surface having S-shaped profile of center lines at negative concavity in tail sections at X>0.7-0.8 and positive concavity f=0.015-0.02 at X> 0-0.7.

Upper generatrices of profiles are so made that at rated conditions, maximum rarefaction does not exceed permissible limits Cmax.perm.. Thickness ratio of profiles is formed according to two laws: from leading edge up to X=0.3, at range of C=0-8% and from X=0.3 to the trailing edge at range C=0-17%; maximum thicknesses of profiles are found at X=0.56-0.66.
