A wing pivot mechanism that is configured to pivot two wings about a single pivot axis of a vehicle, such as an aircraft. The wing pivot mechanism includes a hub, a set of gears positioned at least partially within an interior region of the hub, and two wings that are rotatably connected to the hub.

A wing pivot mechanism that is configured to pivot two wings about a single pivot axis of a vehicle, such as an aircraft. The wing pivot mechanism includes a hub, a set of gears positioned at least partially within an interior region of the hub, and two wings that are rotatably connected to the hub. Each wings includes a gear surface extending therefrom. Each gear of the hub assembly engages a gear of a respective wing such that rotation of the gears of the hub assembly causes rotation of the gears of the wings and pivoting of the wings about the single pivot axis in opposite rotational directions between a stowed position and a deployed position. A releasable locking mechanism is provided for locking the wings in a fixed rotational position in both the deployed position and the stowed position.

1. A wing pivot mechanism that is configured to pivot two wings about a single pivot axis of a vehicle, said wing pivot mechanism comprising: a hub assembly including a hub defining a hollow interior region and a set of gears positioned at least partially within the interior region of the hub, wherein a longitudinal axis of the hub is substantially coincident with the single pivot axis;two wings that are rotatably connected to the hub assembly, wherein each wing includes a gear surface that engages a gear of the hub assembly such that rotation of the gears of the hub assembly causes rotation of the gears of the wings and pivoting of the wings in opposite rotational directions about the single pivot axis between a stowed position and a deployed position; anda releasable locking mechanism for locking the wings in a fixed rotational position in both the deployed position and the stowed position;wherein each wing defines a cylindrical aperture and a longitudinal axis of the cylindrical apertures are positioned in alignment with the single pivot axis;the hub assembly is positioned within the cylindrical aperture of both wings, and the wings pivot about the hub assembly; andthe releasable locking mechanism is positioned on the hub assembly and is configured to releasably engage a recess disposed within one or both of the wings. 2. The wing pivot mechanism of claim 1, wherein the hub assembly further comprises an actuator for releasing the locking mechanism from the recess of the wings to enable the wings to pivot about the pivot axis. 3. The wing pivot mechanism of claim 1 further comprising a stop disposed on either the hub assembly or the wings for preventing the rotation of both wings about the pivot axis beyond a pre-determined rotational range. 4. The wing pivot mechanism of claim 3, wherein the stop is either positioned on or extends from the hub assembly and is positioned within a slot formed in a wing, wherein terminal ends of the slot delimit rotation of the wings. 5. The wing pivot mechanism of claim 1, wherein a height dimension of the hub assembly is substantially equal to a total cumulative thickness of both wing roots. 6. A wing pivot mechanism that is configured to pivot two wings about a single pivot axis of a vehicle, said wing pivot mechanism comprising: a hub that is positioned along the single pivot axis;two wings that are rotatably connected to the hub assembly, wherein each wing defines a cylindrical aperture through which the hub assembly is positioned;a drive mechanism positioned at least partially within an interior region of the hub to enable pivoting of the wings in opposite rotational directions about the single pivot axis between a stowed position and a deployed position; anda stop disposed on either the hub or the wings for preventing the rotation of both wings about the pivot axis beyond a pre-determined rotational range;wherein the stop is either positioned on or extends from the hub and is positioned within a slot formed in a wing, wherein terminal ends of the slot delimit rotation of the wings. 7. The wing pivot mechanism of claim 6 further comprising a gear surface that is either formed on the respective wing or extends from the respective wing, wherein the drive mechanism comprises a set of gears positioned at least partially within the interior region of the hub, andwherein each gear of the gear set is configured to engage a gear of a respective wing such that rotation of the gears of the hub causes rotation of the gears of the wings and pivoting of the wings about the single pivot axis in opposite rotational directions between the stowed position and the deployed position. 8. The wing pivot mechanism of claim 6 further comprising a releasable locking mechanism for locking the wings in a fixed rotational position in both the deployed position and the stowed position. 9. The wing pivot mechanism of claim 8, wherein the releasable locking mechanism is positioned on the hub and is configured to releasably engage a recess disposed within one or both of the wings. 10. The wing pivot mechanism of claim 9, wherein the hub further comprises an actuator for releasing the locking mechanism from the recess of the wings to enable the wings to pivot about the pivot axis. 11. The wing pivot mechanism of claim 6, wherein a height dimension of the hub is substantially equal to a total cumulative thickness of both wing roots.
