Abstract

FIELD: transport. ^ SUBSTANCE: aircraft wing comprises inner bearing carcass, top and bottom envelopments, flap and aileron. Said wing represents a flat plate with thickness equal along the profile and sharpened front tip. Top envelopment has dissectors each being formed by ridges and recesses to make airflow jets move in zigzag-like manner. ^ EFFECT: increased lift. ^ 4 dwg

Description

The invention relates to aviation. As you know, the wings create an airplane’s lift.

The aircraft wing is known from the book "Designing Aircraft Structures" of the Engineering Edition for 1987; authors are E.S. Voit, A.I. Endogur, Z.A. Malik-Sargsyan, I.M. Alyavdin. The wing structure is shown in Fig. P24 p. 403 and consists of an internal supporting frame, upper and lower skins, flaps and ailerons. The wing has an aerodynamic profile. The disadvantages of this wing include a large drag and a small lift.

Known aircraft according to the patent of the Russian Federation 2190557. The wing of this aircraft is made in the form of a plate of uniform thickness along the profile and pointed in front.

Its design consists of an internal supporting frame, upper and lower skins, flap and aileron. The lower wing skin is even and smooth, and the upper wing skin is wavy. The lifting force of this wing is formed as a result of the fact that the air flow at the leading edge of the wing is divided into upper and lower. The air path on the upper, undulating surface is longer than on the lower, even surface, as a result of which the pressure on the lower skin is greater than on the upper. The difference in these pressures creates lift. The disadvantages of this wing are its large dead weight, high drag and low lift.

The purpose of the invention is the creation of a wing of a new type of aircraft, distinctive from the wings of the aerodynamic and wavy profiles, but capable of creating lift.

This goal is achieved by the fact that the proposed wing is made in the form of a rectangular plate in terms of uniform thickness along a profile pointed at the front, and its design consists of a supporting inner frame, upper and lower skin, flap and aileron. The lower skin is flat and smooth. Dividers are installed on the upper skin, each of which is formed by humps and a saddle. They cut the air stream into separate jets. Having passed several dividers, air jets increase speed and acquire a zigzag form of movement. The path of the zigzag jets on the upper wing skin is longer than the path of a continuous air stream moving along the lower skin of the wing.

Since the speed of movement of air jets on the upper wing skin is much greater than the speed of movement of the lower ceiling, the pressure on the upper skin is much less than the pressure on the lower skin. The difference in these pressures is the lifting force of the wing.

Distinctive features of the claimed invention from the invention according to the patent of the Russian Federation 2190557.

1. On the upper skin of the wing are mounted dividers, each of which is formed by humps and a saddle. The wing according to the patent of the Russian Federation 2190557 the upper skin is wavy.

2. The air flow on the upper wing skin by dividers is divided into separate jets, which flow around them both on the right and on the left and rise upwards from the skin. At the wing according to the patent of the Russian Federation 2190557, the air flow on the upper skin moves in waves.

3. You need to install the wing on the fuselage at a certain angle of attack. In the patent of the Russian Federation 2190557, the wing on the fuselage is installed at a zero angle of attack.

The proposed wing is illustrated by drawings.

The wing design includes:

1 - fuselage

2 - wing

3 - flap

4 - aileron,

5 - supporting structure,

6 - lower skin

7 - upper skin,

8 - hump,

9 - saddle,

10 - left stream,

11 - the right stream,

12 - jet rising up

13 - dividers.

Wing work.

After the “Take-off” command, the aircraft begins to take off. Airflow approaches the leading edge of the wing and is divided into upper and lower. The lower flow without obstacles with a total mass passes under the lower skin of the wing. The upper stream, having passed the pointed edge, begins to move above the upper casing and falls on the dividers 13. The function of the dividers is that they cut the air stream into separate jets 10, 11, 12. The jets 10 and 11 flow around the humps 8 of the divider to the left, and on the right, and the jet 12 rises along the saddle 9 up. The jets 10, 11, 12, moving between the dividers, acquire a zigzag shape of movement, increase speed and travel from the front edge of the wing to the flap, greater than the path of a straight air flow from below. Above the upper wing skin, the pressure becomes much less than on the lower skin. The difference between the lower and upper pressures and creates the lifting force of the wing.
