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

[0037] A variable camber wing, such as Figure 1-7 As shown, it includes a front wing segment 100 with constant camber, a rear wing segment 200 with variable camber, and a wing skin 300 .

[0038] The wing skin 300 in this example is connected with the front section 100 of the wing in a riveted manner. In order to better follow the change of the curvature of the trailing edge section 200 of the wing, the wing skin 300 adopts an elastic skin to follow the shape of the wing. Adaptive deformation occurs when the trailing edge section 200 becomes curved.

[0039] The trailing edge section 200 of the wing includes three rib joints 200a, 200b, and 200c connected in series. The structure of the rib joint 200a closest to the leading edge of the wing will be described in detail below. The rib joint 200 a includes four closed-loop rod mechanisms 210 , a parallel rod mechanism 220 , a scissor mechanism 230 and a driving mechanism 240 .

[0040] Such as Figure 5 As shown, the closed-l...

Abstract

The invention provides a variable camber wing capable of continuously bending the trailing edge of the wing, comprising a front section of the wing with a constant camber, a trailing section of the wing with variable camber, and a wing skin, wherein the wing The trailing edge section includes multiple rib joints connected in series, and the rib joints include multiple closed-loop rod mechanisms arranged side by side, a parallel rod mechanism used for synchronous linkage between multiple closed-loop rod mechanisms, and a parallel rod mechanism used to drive multiple closed-loop rod mechanisms. A scissor mechanism for pitching and rotating, and a driving mechanism for driving the scissor mechanism to extend and shorten. The present invention is based on the characteristic that the scissor mechanism can be extended and shortened, and can realize large-scale bending in the upper and lower directions, thereby improving the pressure distribution of the wing, increasing the maximum lift coefficient of the wing, and broadening the aircraft's ability to respond to different cruising conditions. adaptability.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment, and in particular relates to a variable-camber wing capable of realizing continuous bending of the trailing edge of the wing. Background technique [0002] The wing is the provider of aircraft lift and an important part that determines the flight capability of the aircraft. Its main function is to generate aerodynamic lift to ensure the performance and maneuverability of the aircraft in all flight states specified by 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 flight conditions; on the other hand, when the tradition...
