A foldable wing for use with a very high altitude aircraft capable of operating at an altitude at or above 85,000 feet is disclosed. The foldable wing may employ a spiral fold deployment, wherein a hinge between each segment of the foldable wing is slightly offset from the perpendicular. Successively positioned wing segments fold over one another. Alternatively, the hinges are substantially perpendicular so that each respective wing segment folds linearly against the next wing segment. An inflatable rib, with inflatable arms, can be inflated to provide a force against two adjacent arms, thereby deploying the wing segments through a full 180° of rotation.

1. A foldable wing for use in a very high altitude aircraft capable of operating at an altitude at or above 85,000 feet, the foldable wing comprising: a first spar section, a second spar section, and a third spar section, wherein the first spar section is positioned closest to a fuselage of the very
1. A foldable wing for use in a very high altitude aircraft capable of operating at an altitude at or above 85,000 feet, the foldable wing comprising: a first spar section, a second spar section, and a third spar section, wherein the first spar section is positioned closest to a fuselage of the very high altitude aircraft, the second spar section is positioned adjacent to the first spar section, and the third spar section is positioned adjacent to the second spar section and farthest away from the fuselage;a first hinge and a second hinge, wherein the first hinge rotationally connects the first spar section to the second spar section at a first angle, and whereinthe second hinge rotationally connects the second spar section to the third spar section at the first angle, and further whereinthe third spar section is configured to rotate substantially 180° such that an outermost portion of the third spar section is located vertically above an innermost portion of the second spar section, and further whereinthe second spar section is configured to rotate substantially 180° such that an outermost portion of the second spar section is located vertically above an innermost portion of the first spar section, and the outermost portion of the third spar section is located vertically above an outermost portion of the first spar section, andwherein each of the plurality of spar sections is configured to receive and transfer a gas, the received and transferred gas causing each of the plurality of spar sections to rotate. 2. The foldable wing according to claim 1, further comprising at least a fourth spar section and a third hinge, the fourth spar section being configured to rotate substantially 180° such that an outermost portion of the fourth spar section is located vertically above an innermost portion of the third spar section. 3. The foldable wing according to claim 1, wherein the first angle has a measure of between about 1° and about 4°. 4. A method for operating a foldable wing for use in a very high altitude aircraft capable of operating at an altitude at or above 85,000 feet, the method comprising: positioning a first spar section, a second spar section, and a third spar section, such that (i) the first spar section is positioned closest to a fuselage of the very high altitude aircraft, (ii) the second spar section is positioned adjacent to the first spar section, and (iii) the third spar section is positioned adjacent to the second spar section and farthest away from the fuselage;positioning a first hinge to rotationally connect the first spar section to the second spar section at a first angle;positioning a second hinge to rotationally connect the second spar section to the third spar section at the first angle;rotating the third spar section with respect to the second spar section substantially 180° such that an outermost portion of the third spar section is located vertically above an innermost portion of the second spar section;rotating the second spar section with respect to the first spar section substantially 180° such that an outermost portion of the second spar section is located vertically above an innermost portion of the first spar section, and the outermost portion of the third spar section is located vertically above an outermost portion of the first spar section; andprovide a gas to each of the plurality of spar sections to cause each of the plurality of spar sections to rotate with respect to an adjacent spar. 5. The method according to claim 4, further comprising the step of rotating a fourth spar section with respect to the third spar section at a third hinge, substantially 180° such that an outermost portion of the fourth spar section is located vertically above an innermost portion of the third spar section. 6. The method according to claim 4, wherein the first angle has a measure of between about 1° and about 4°.
