Embodiment Construction

[0008] Figure 1a-1c Schematically shows the folding manner of the three-segment double-folding wing according to an embodiment of the present invention.

[0009] figure 2 Schematically shows the working principle of the three-segment double folding wing according to one embodiment of the present invention.

[0010] image 3 An auxiliary torsion spring arrangement according to one embodiment of the invention is shown.

[0011] Such as figure 2 As shown, the folding wing according to an embodiment of the present invention includes three sections of airfoils: the inner wing (2), the middle wing (4), and the outer wing (8), wherein the inner wing (2) is fused with the fuselage. In this embodiment, the planar link mechanism is used to realize the double folding of the airfoil; in order to ensure that the planar link mechanism has enough movement space in the wing, the planar link mechanism is set at the position where the maximum thickness of the airfoil is located. plane. ...

Abstract

A single folding mode is mostly adopted for the traditional folding wing, and has the limitation on the effect of reducing the ground occupied spaces of an aircraft (especially a high-span-cord-ratio airplane). The invention relates to the design of a novel folding wing capable of reducing the horizontal occupied spaces in ground driving and storage of the aircraft effectively. A three-section dual-folding wing provided by the invention is separated into three sections including an inner wing, a middle wing and an outer wing; and the wing surface is folded twice through a linkage rod folding mechanism. Auxiliary torque is provided for the inner wing hinge part by utilizing a torsional spring, and the driving performance of a folding system is improved; the wing folding / unfolding motion is continuous and stable; and the wing surface can rotate at uniform speed, and the control principle is simple.

Description

Technical field: [0001] The invention relates to the design of folding wings in aviation aircraft, and is especially suitable for the technical fields of carrier-based aircraft, land-air dual-purpose aircraft and flying cars. technical background: [0002] Folding wings are mainly used in carrier-based aircraft, missiles and drones. At present, most of the folding wings are double-segment single-folding wing surfaces. When the aircraft is stored, the outer wings are folded upwards, and the horizontal space occupied by the ground is reduced. However, for aircraft and flying cars with a large aspect ratio, after the wing surface is folded once, the lateral dimension of the inner wing still occupies a large space, which is not conducive to ground driving and storage. For this reason, a new type of folding wing is designed to further reduce the space occupied by the folding wing aircraft for ground driving and storage. Invention content: [0003] The invention focuses on a n...
