A uniaxial wing folding mechanism

Abstract

The invention discloses a uniaxial wing folding mechanism, which is installed between the inner wing and the outer wing, comprising a folding shaft on which the inner wing joint lugs and the outer wing joint lugs are installed, and a folding shaft rotatably mounted on the folding shaft. mechanism; the folding mechanism includes a rotary actuator that is rotationally connected to the folding shaft, an outer wing folding link that is rotatably mounted on the output shaft of the rotary actuator, and an inner wing that is fixedly mounted on the output shaft of the rotary actuator Folding connecting rod; the outer wing folding connecting rod and outer wing joint lugs are respectively connected to the outer wing; the inner wing folding connecting rod and inner wing joint ear are respectively connected to the inner wing. The beneficial effects of the present invention are: the present invention takes up little space, does not affect the aerodynamic profile of the wing, has a large folding angle, light mechanism structure, is easy to maintain, and is easy to implement, and is suitable for carrier-based aircraft wing folding engineering applications; the present invention does not require design The envelope is bulging, so that the wing folding mechanism can fold at a large angle without affecting the aerodynamic shape of the wing.

Description

technical field [0001] The invention relates to the technical field of aircraft wing folding, in particular to a single-axis wing folding mechanism. Background technique [0002] Modern advanced aircraft carrier-based aircraft is an important part of the combat capability of aircraft carrier battle formations. To improve the combat capabilities of naval aircraft carrier formations, the support of advanced aircraft carrier-based aircraft technology is urgently needed. Under the condition of limited aircraft carrier deck and hangar space, the carrier-based aircraft needs to have the function of wing folding. The wings are in the unfolded state during the mission, and the wings are in the folded state when entering the warehouse and mooring the deck. [0003] The carrier-based aircraft has a span width limit and needs to fold its wings. At the same time, because the height of the aircraft carrier hangar also has an aircraft height limit, it is required that the height of the ai...

Problems solved by technology

The traditional single-axis wing folding mechanism does not affect the aerodynamic shape. The folding rotation axis can only be arranged in the middle of the airfoil thickness, and the wing folding angle can only reach about 90°. To increase the folding angle, you need Protrude the folded rotation axis from the airfoil surface, and design the envelope bulge, which has a certain influence on the aerodynamic outer wing of the wing
