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; andfirst 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. 2. A hinge apparatus for an aircraft with a foldable wing, comprising: a first hinge member, comprising: a first connection section connected to a first portion of the wing; anda first mating section comprising a first guide surface;a second hinge member, comprising: a second connection section connected to a second portion of the wing; anda second mating section coupled to the first mating section and movable, in rotation about an axis and in translation along the axis, between stowed and deployed positions, the second mating section comprising a second guide surface cooperating with the first guide surface to guide the second hinge member in translational movement along the axis as the second mating member rotates about the axis; anda bias member applying rotational and translational force on the second hinge member, to bias the second mating section from the stowed position toward the deployed position. 3. The apparatus of claim 2, wherein the first and second hinge members have cross sections with identical airfoil shapes. 4. The apparatus of claim 3, wherein: lines perpendicular to the cross sections of the first and second hinge members, when the first and second hinge members are in the stowed position, lie in first and second planes perpendicular to the axis; andthe lines perpendicular to the cross sections of the first and second hinge members, when the first and second hinge members are in the deployed position, are collinear. 5. The apparatus of claim 2, wherein: the first guide surface comprises a pin; andthe second guide surface comprises a groove. 6. The apparatus of claim 2, wherein: the first hinge member comprises: a first cylindrical member; anda second cylindrical member coaxial with and surrounding the first cylindrical member, the second cylindrical member comprising a projecting member extending radially outward from an outer surface of the second cylindrical member;the second hinge member comprises a third cylindrical member having an inner surface and a groove formed in the inner surface; andthe third cylindrical member coaxially surrounds the second cylindrical member such that the projecting member engages with the groove. 7. The apparatus of claim 6, wherein the bias member comprises a coil spring coaxial with and positioned between the first and second cylindrical members. 8. The apparatus of claim 6, comprising a fairing covering the first, second, and third cylindrical members. 9. The apparatus of claim 2, comprising a mounting member, the mounting member having a cylindrical member attached thereto. 10. The apparatus of claim 9, wherein: the first connection section comprises a first ring member rotatable about the cylindrical member and coaxial with the cylindrical member; andthe second connection section comprises a second ring member rotatable about the cylindrical member and coaxial with the cylindrical member. 11. A hinge apparatus for a folding wing, comprising: inboard and outboard hinge members, the inboard and outboard hinge members: being respectively connectable to associated inboard and outboard wing sections;being coupled together; andbeing rotatably moveable about an axis between stowed and deployed wing positions, at least one of the inboard and outboard hinge members being translationally moveable along the axis between the stowed and the deployed positions; anda bias member coupled to the inboard and outboard hinge members and applying rotational and translational force to bias the inboard and outboard hinge members from the stowed wing position toward the deployed wing position.
