Embodiment Construction

[0036] Such as figure 1 As shown in -7, a flexible deformable wing includes N wing box modules 1, N-1 flexible hinges 2, a skin 3 and a drive module.

[0037] Among them, the flexible hinge 2 is arranged between two adjacent wing box modules 1 and connects the two wing box modules 1. The N wing box modules 1 connected to each other form a prefabricated wing-shaped structure, and the skin 3 is covered on the prefabricated On the outer edge of the wing-shaped structure, the drive module is used to cooperatively control the spanwise camber and sweep angle of multiple wing box modules 1 .

[0038] Furthermore, the skin 3 is preferably a highly elastic flexible rubber material, installed on the periphery of the flexible deformable wing formed by the prefabricated wing-shaped structure, and fixed by means of, for example, aviation screws.

[0039] Such as Figure 4As shown, the wing box module 1 includes: a left rib 11, a right rib 12, a front spar 13, a rear spar 14, and the left...

Abstract

The invention provides a flexible deformed wing. The flexible deformed wing comprises a plurality of wing box modules, flexible hinges, a skin and a drive module, wherein the wing box modules which are connected with one another form a prefabricated wing-shaped structure body, the outer edge of the prefabricated wing-shaped structure body is covered with the skin, and the drive module is used forcontrolling the spanwise bending degree and the sweep angle of the wing box modules. Each wing box module comprises two ribs and two wing spars, wherein the two ribs are oppositely arranged in the length direction of the prefabricated wing-shaped structure body, the two wing spars are oppositely arranged in the width direction of the prefabricated wing-shaped structure body, and the two wing sparsare connected with each other through the two ribs to form a wing box; and each flexible hinge has a bending rotation axis and a sweep angle rotation axis which are perpendicular to each other, and the drive module controls the wing box modules to separately change the spanwise bending degree and the sweep angle around the bending rotation axes and the sweep angle rotation axes. The spanwise bending degree and the sweep angle of the wing can be continuously and smoothly changed, and the flexible deformed wing has the advantages of high structural strength, light weight and the like.

Description

technical field [0001] The invention belongs to the technical field of aerospace equipment, in particular to a flexible deformable wing with adjustable spanwise camber and sweep angle. Background technique [0002] In recent years, with the continuous improvement of military reconnaissance strikes, long-distance transportation and medical disaster relief, the requirements for aircraft performance and the development of technology, advanced aircraft are developing in the direction of intelligence, high efficiency and reconnaissance / strike integration. In this case, the traditional fixed wing can no longer meet the application requirements, and the deformable wing that can adapt to various flight missions and different environmental conditions and achieve optimal flight performance has attracted increasing attention and research. The flexible deformable wing refers to an adaptive deformable wing that can adapt to different environments and different flight requirements through...
