Problems solved by technology

[0003] 1) Structural integrity is compromised;
[0004] 2) When folded, the internal components and systems of the structure are exposed, which are vulnerable to pollution, corrosion or other accidental damage;
[0005] 3) Due to reasons such as support stiffness and structural exposure, the wing area cannot be changed during flight;
[0006] 4) The structural system that maintains the fold is heavy

Embodiment Construction

[0037] Below in conjunction with accompanying drawing, explain in detail the structural form and working method according to this national defense patent.

[0038] figure 1 The illustrated embodiment is a general scheme schematic of a conformal folding wing. It is composed of three parts: an inner wing section 1, an outer wing section 2, and a conformal rotator 3. The axis of rotation of the conformal gyratory is parallel to the heading, so as to ensure that no additional aerodynamic resistance is brought about when the outer wing segments are folded.

[0039] figure 2 The illustrated embodiment is a schematic diagram of a partially fused form of a conformal gyrator. The shape between the inner wing section 1 and the outer wing section 2 and the conformal rotor 3 has a wing-body fusion zone 4, and the front and rear parts of the conformal rotor protrude from the front and rear edges of the wing. This design can rectify the airflow , reducing separation and thus improving ...

Abstract

The invention relates to a shape-preserving foldable wing suitable for the occasions with the requirements of changing the pneumatic area of aircraft wings and saving the parking space. The foldable wing is composed of an inner wing section, an outer wing section and a shape-preserving rotation body. According to the layout design, the pneumatic continuity of the shape of the wing is effectively maintained in the folding process, and enough supporting rigidity can be provided. Thus, the shape-preserving foldable wing can meet the folding requirement when aircrafts are parked on the ground and can be folded by a specific angle according to the flight control requirements in the flying process.

Description

technical field [0001] The invention relates to a shape-conserving folding wing which can be used for changing the aerodynamic area of ​​the aircraft wing, saving parking space and the like. Background technique [0002] Usually, due to the limited space of the aircraft carrier, in order to park more aircraft, the wings of the carrier-based aircraft are required to be foldable. These folded wing mechanisms often rotate split-like around a rotating shaft on the upper surface of the wing. For this traditional shipboard folding wing structure, it has the following disadvantages: [0003] 1) Structural integrity is compromised; [0004] 2) When folded, the internal components and systems of the structure are exposed, which are vulnerable to pollution, corrosion or other accidental damage; [0005] 3) Due to reasons such as support stiffness and structural exposure, the wing area cannot be changed during flight; [0006] 4) The structural system for maintaining folding is hea...
