Problems solved by technology

However, with the addition of winglets, the structure of the wing tip will be more complicated to assemble the winglets, and the shape of the winglets varies with different aircraft models
[0003] At present, the winglet is a complex winglet structure composed of beams, ribs and skins, and is designed and formed integrally with the wing as a whole. The overall design considerations are complex and cannot be disassembled separately after forming

Embodiment Construction

[0023] The implementation process of the embodiment of the present invention will be described in detail below in conjunction with the accompanying drawings. It should be noted that the embodiments described below by referring to the accompanying drawings are exemplary, and are only used to explain the present invention, and should not be construed as limiting the present invention.

[0024] Embodiments of the present invention provide a detachable aircraft winglet, such as figure 1 As shown, the aircraft includes an outer wing 1 with a smooth upper curved surface, and the winglet 2 is arranged on the tip of the outer wing 1, and the winglet and the outer wing have a common cross-sectional airfoil, such as figure 2 A-A section in .

[0025] The detachable winglet 2 can be installed on the wingtip of the outer wing 1 in various ways such as bonding, slotting, and buckling.

[0026] Further, the upper curved surface of the winglet 2 is tangent to the upper curved surface of t...

Abstract

The invention discloses detachable airplane winglets and a design method thereof. An airplane comprises outer wings with smooth upper curved surfaces, wherein small wings are arranged on wing tips ofthe outer wings, and the small wings have common section aerofoils with the outer wings. The design method comprises the following steps: S1, scaling the common section aerofoils of the outer rings and the small wings to obtain upper end surface aerofoils of the small wings; S2, determining front edge splines and rear splines of the small wings; and S3, controlling laying off by the section aerofoils of the wing tips, the upper end surface aerofoils of the small wings, and the front edge splines and the rear edge splines of the small wings to generate the winglets. The winglets can be independently detachable, are simple in structure and are high in practicability. The design method is quick and flexible, and is suitable for various wings.

Description

technical field [0001] The invention relates to the field of aviation technology, in particular to a detachable aircraft winglet and a design method thereof. Background technique [0002] The lift required for the aircraft to maintain normal flight is generated by the pressure difference between the upper and lower surfaces of the wing. The air on the lower surface of the wing near the wingtip will flow around to the upper surface, reducing the pressure difference between the upper and lower surfaces of the wing near the wingtip. In order to weaken the influence of this flow-around phenomenon on lift, winglets are installed on the wingtips of many aircraft to hinder the air flow around the upper and lower surfaces, reduce the damage to lift caused by the flow around, and achieve the purpose of increasing lift. However, with the addition of winglets, the wing end structure will be more complicated for assembling the winglets, and the shape of the winglets varies with differen...
