A conformal folding wing

Abstract

The invention belongs to the technical field of aircraft design and relates to a conformal folding wing that can change the aerodynamic area of ​​an aircraft wing and save parking space. The folding wing involved in the invention consists of three parts: an inner wing section, an outer wing section and a conformal rotary body. The wing designed according to the conformal folding wing layout effectively maintains the aerodynamic continuity of the wing shape when folded. It also provides sufficient support stiffness. Therefore, the invention can not only meet the folding requirements of the wings when the aircraft is parked on the ground, but can also achieve folding at a specified angle according to flight control requirements during flight.

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...
