A conformal folding wing

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 belongs to the technical field of aircraft design, and relates to a shape-conserving folding wing capable of changing the aerodynamic area of ​​an aircraft wing and saving parking space. 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 syst...
