Folding structure and folding method of aircraft wing

Abstract

The invention relates to a folding structure and folding method of an aircraft wing. The aircraft wing comprises a central wing and a folding wing, a folding mechanism is arranged between the central wing and the folding wing, the folding mechanism comprises a Z-shaped rotating shaft and a hydraulic telescopic rod, and the two ends of the Z-shaped rotating shaft and the two ends of the hydraulic telescopic rod are connected with the central wing and the folding wing respectively. The Z-shaped rotating shaft is provided with a first rotating surface and a second rotating surface which are perpendicular to each other, the first rotating surface is parallel to a rear beam of the folding wing, the second rotating surface is perpendicular to a rear beam of the central wing, and the hydraulic telescopic rod can push the folding wing to rotate around the first rotating surface and the second rotating surface, so that the folding wing is folded downwards and backwards relative to the central wing.

Description

technical field [0001] The invention relates to the technical field of aircraft structure design, in particular to an aircraft wing folding structure and a folding method. Background technique [0002] Since more fighter jets and other types of military carrier-based aircraft need to be docked on the deck of an aircraft carrier, most of the carrier-based aircraft use upwardly folded wings to save deck space, thereby docking more fighter jets. However, because the shipboard early warning aircraft is equipped with a disc-shaped shipboard radar on the top of the fuselage, it cannot use the upwardly folded wings. If the wings are folded too much, they will bump into the radar. If they are folded less, its footprint will not be reduced. How many. However, due to its large size, the non-folding carrier-based early warning aircraft will occupy the deck space of at least two carrier-based aircraft, resulting in a reduction in the total number of boarding aircraft.
