Description

The invention relates to aircraft wings having a surface variable in flight. In the proposed wing, at its trailing edge, there is a row of rotary vanes, which form an additional bearing surface when they are translated into a horizontal position.

In FIG. 1 shows a section of the wing, FIG. 2, 2a, 26, 2b — various types of arrangement of the blades; FIG. 3 and 4 show a part of the wing with a horizontal vertical position of the blades.

The wing has a modern normal type of selected profile and a rational form in span and elongation.

In the rear part of the wing, at some distance from each other, are located along the wing of the blade 2 of a streamlined shape. The blades are fixed on the axles, embedded in the bearings in the wing (Fig. 1). The CCP passes along the shoulder blades in any advantageous place along the width of the shoulder blade, {Fig. 2, 2a, 26, 2c).

The blades are controlled from the pilot's seat and can be placed at his desire in a vertical, horizontal or any intermediate position. With the horizontal position of the blades, the surface of the wings increases and, conversely, when the position is northenhall;

In the vertical position, the shoulder blades form, as it were, the keels, and in the horizontal position, they are a continuation of the wing along its depth. A gap is formed between the wing and the shoulder blades in their horizontal position, used to deflate the boundary layer of air.

The purpose of such a wing is, on desire, to increase or decrease the bearing surface of the wings during takeoff or landing, or when manipulated in air.

Subject invention

A wing for aircraft with a variable surface in flight, characterized by the use of a number of blades mounted at the rear edge of the wing, -turning axes lying in the direction of flight and forming in the horizontal position an additional carrying surface.
