Problems solved by technology

However, when the traditional wing is designed, it only considers the best performance in a specific flight situation, and it is difficult to meet the multi-tasking flight conditions; on the other hand, when the traditional rigid wing is deformed, it will inevitably produce Gaps and sudden changes in curvature that break the continuity of the wing surface, which degrades the aerodynamic properties of the aircraft

Embodiment Construction

[0032] A variable camber wing, such as Figure 1-6 As shown, it includes a wing leading edge 100 with constant camber, a wing trailing edge 200 with variable camber, and wing skin.

[0033] In this example, the wing skin (not shown) is connected with the leading edge 100 of the wing in a riveted manner. In order to better follow the curvature of the trailing edge 200 of the wing, the skin, to produce adaptive deformation when the trailing edge 200 of the random wing changes curvature.

[0034] The trailing edge 200 of the wing includes five sub-ribs 210 connected in sequence, two adjacent sub-ribs 210 are connected by a flexible hinge 220, and the five sub-ribs 210 are driven by the driving device 230 to bend upward or downward. curved, wherein, to accommodate the shape of the wing trailing edge 200, the five sub-ribs 210 are not identical in shape, see figure 1 , figure 2 , are respectively the first sub-rib 210a, the second sub-rib 210b, the third sub-rib 210c, the fourt...

Abstract

The invention provides a camber-variable wing trailing edge and a wing capable of realizing continuous bending of the wing trailing edge. The camber-variable wing trailing edge at least comprises a front sub-wing rib, a rear sub-wing rib and a flexible hinge for connecting the front sub-wing rib and the rear sub-wing rib, and the flexible hinge comprises a first cross reed and a second cross reed;and the first cross reed and the second cross reed are arranged in a spatial cross line manner in the front-rear direction of the wing trailing edge. The wing trailing edge is of a sectional structure, and the adjacent sub-wing ribs are connected through the flexible hinges, and the wing trailing edge has the advantages of being high in flexibility, simple in structure and light in weight.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment, and in particular relates to a variable camber rear edge and wing based on a flexible hinge to realize continuous bending of the rear edge of the wing. Background technique [0002] The wing is the provider of the lift of the aircraft and is an important component that determines the flight capability of the aircraft. Its main function is to generate aerodynamic lift to ensure the aircraft performance and maneuverability of the aircraft in all flight states specified in the technical requirements. The traditional fixed rigid wing uses flaps, leading edge slats, etc. as the lift-increasing device of the wing, and improves the aerodynamic performance of the aircraft by changing the curvature and shape of the wing section. However, when the traditional wing is designed, it only considers the best performance in a specific flight situation, and it is difficult to meet the multi-tasking fl...
