Folding wing for aircraft

摘要

A folding wing for an aircraft comprises first and second inboard wing sections, and first and second outboard wing sections. The first and second inboard wing sections rotate about a centerline hinge, and a centerline spring applies force to the first and second inboard wing sections to rotate the first and second inboard wing sections from a stowed position to a deployed position. At least one of the first and second inboard wing sections translates along the axis of rotation of the first and second inboard wing sections as they move from the stowed to the deployed positions. The first and second outboard wing sections rotate between the stowed and the deployed positions about first and second outboard hinges.

1. A foldable wing for an aircraft, comprising:
a mounting member mountable on a fuselage of the aircraft and having a mount axis; first and second inboard wing sections; first and second outboard wing sections; a centerline hinge assembly comprising:
first and second centerline hinge members, the first and second centerline hinge members being:
coupled to the mounting member;respectively connected to the first and second inboard wing sections; andmovable in rotation about the mount axis and in translation along the mount axis, between stowed and deployed inboard wing section positions, with at least one of the first or second centerline hinge members being translationally moveable along the mount axis;a centerline bias member applying rotational force to the first and second centerline hinge members and translational force to at least one of the first or second centerline hinge members, to bias the first and second centerline hinge members from the stowed inboard wing section position toward the deployed inboard wing section position; and first and second wing hinge assemblies respectively comprising:
first and second inboard hinge members respectively connected to the first and second inboard wing sections;first and second outboard hinge members, the first and second outboard hinge members being:
respectively connected to the first and second outboard wing sections;respectively coupled to the first and second inboard hinge members; androtatably moveable about respective first and second wing axes between stowed and deployed outboard wing section positions, with at least one of the first or second inboard or outboard hinge members being translationally moveable along the wing axes;first and second wing bias members, the first and second wing bias members:
being respectively coupled to the first and second inboard hinge members and to the first and second outboard hinge members; andrespectively applying, to the first and second inboard and outboard hinge members, rotational and translational force to bias the first and second outboard hinge members from the stowed outboard wing section position toward the deployed outboard wing section position.
