Abstract

A wing module for an aerial vehicle in which the wing module has a flight configuration and an access configuration. The wing module includes an external wing skin having an upper skin with an upper surface having a curved profile and a lower skin forming the leading and trailing edges and having a generally planar lower surface. A hinge joint couples the upper and lower skins enabling relative rotation of the upper and lower skins between the flight configuration and the access configuration. The hinge joint is proximate the leading edge. An interior cavity is formed at least partially within the lower skin. In the flight configuration, the upper and lower skins have an airfoil cross section. In the access configuration, the upper and lower skins are split in the chordwise direction such that distal ends of the first and second skins are separated providing access to the interior cavity.

First claim

What is claimed is:

1. A wing module for an aerial vehicle, the wing module having a flight configuration and an access configuration, the wing module comprising:
an external wing skin including an upper skin having an upper surface with a curved profile and a lower skin having leading and trailing edges and a lower surface;
a hinge joint coupling the upper and lower skins enabling relative rotation of the upper and lower skins between the flight configuration and the access configuration, the hinge joint positioned at a forward portion of the upper and lower skins; and
an interior cavity formed at least partially within the lower skin;
wherein, in the flight configuration, the upper and lower skins form an airfoil cross section; and
wherein, in the access configuration, the upper and lower skins are split in the chordwise direction such that distal ends of the first and second skins are separated providing access to the interior cavity.

2. The wing module as recited in claim 1 wherein the hinge joint defines a spanwise axis of rotation for the upper and lower skins.

3. The wing module as recited in claim 1 wherein the hinge joint further comprises first and second hinge joint elements disposed on opposites sides of the external wing skin.

4. The wing module as recited in claim 1 wherein the interior cavity is formed entirely within the lower skin.

5. The wing module as recited in claim 1 wherein the interior cavity is formed at least partially within the upper skin.

6. The wing module as recited in claim 1 further comprising an array of pylon mounts coupled to the external wing skin.

7. The wing module as recited in claim 6 wherein the array of pylon mounts are coupled to the upper surface of the upper wing skin.

8. The wing module as recited in claim 7 wherein the array of pylon mounts includes first and second forward pylon mounts and first and second aft pylon mounts.

9. The wing module as recited in claim 6 wherein the array of pylon mounts are coupled to the lower surface of the lower wing skin.

10. The wing module as recited in claim 9 wherein the array of pylon mounts includes first and second forward pylon mounts and first and second aft pylon mounts.

11. The wing module as recited in claim 1 further comprising operational components supported by the interior cavity.

12. The wing module as recited in claim 11 wherein the operational components include an avionics package.

13. The wing module as recited in claim 11 wherein the operational components include a sensor package.

14. The wing module as recited in claim 1 further comprising nonoperational components supported by the interior cavity.

15. The wing module as recited in claim 14 wherein the nonoperational components include a removable payload.

16. An unmanned aerial vehicle comprising:
an airframe including first and second wings each having an airfoil cross section in a flight configuration and first and second pylons extending between a lower surface of the first wing and an upper surface of the second wing;
a thrust array coupled to the airframe including first and second propulsion assemblies coupled to the first wing and third and fourth propulsion assemblies coupled to the second wing;
an electric power system operably associated with the thrust array and operable to provide power to each propulsion assembly; and
a flight control system operably associated with the thrust array and operable to independently control the speed of each propulsion assembly;
wherein, the first wing has an external wing skin including an upper skin having an upper surface with a curved profile and a lower skin having leading and trailing edges and the lower surface, a hinge joint coupling the upper and lower skins enabling relative rotation of the upper and lower skins between the flight configuration and an access configuration, the hinge joint positioned at a forward portion of the upper and lower skins and an interior cavity formed at least partially within the lower skin; and
wherein, in the access configuration of the first wing, the upper and lower skins are split in the chordwise direction such that distal ends of the first and second skins are separated providing access to the interior cavity.

17. The unmanned aerial vehicle as recited in claim 16 wherein the second wing has an external wing skin including an upper skin having the upper surface with a curved profile and a lower skin having leading and trailing edges and a lower surface, a hinge joint coupling the upper and lower skins enabling relative rotation of the upper and lower skins between the flight configuration and an access configuration, the hinge joint positioned at a forward portion of the upper and lower skins and an interior cavity formed at least partially within the lower skin; and
wherein, in the access configuration of the second wing, the upper and lower skins are split in the chordwise direction such that distal ends of the first and second skins are separated providing access to the interior cavity.

18. The unmanned aerial vehicle as recited in claim 17 further comprising an avionics package supported by the interior cavity of the first wing and a sensor package supported by the interior cavity of the second wing.

19. The unmanned aerial vehicle as recited in claim 17 further comprising nonoperational components supported by the interior cavity of the first wing and operational components supported by the interior cavity of the second wing.

20. The unmanned aerial vehicle as recited in claim 19 wherein the nonoperational components include a removable payload and operational components include an avionics package.
