Abstract

Systems, devices, and methods for a ground support system for an unmanned aerial vehicle (UAV) including: at least one handling fixture, where each handling fixture is configured to support at least one wing panel of the UAV; and at least one dolly, where each dolly is configured to receive at least one landing pod of the UAV, and where each landing pod supports at least one wing panel of the UAV; where the at least one handling fixture and the at least one dolly are configured to move and rotate two or more wing panels to align the two or more wing panels with each other for assembly of the UAV; and where the at least one dolly further allows for transportation of the UAV over uneven terrain.

Claims (38)

1 . A ground support system for an unmanned aerial vehicle (UAV) comprising:

at least one or more handling fixtures, wherein each handling fixture is configured to support at least one wing panel of the UAV; and

at least one or more dollys, wherein each dolly is configured to receive at least one landing pod of the UAV, and wherein each landing pod supports at least one wing panel of the UAV;

wherein two or more wing panels of the UAV are configured to align with each other, by at least one of: the at least one or more handling fixtures and the at least one or more dollys, for assembly of the UAV.

2 . The ground support system of claim 1 , wherein the at least one or more handling fixtures and the at least one or more dollys are configured to move and rotate two or more wing panels to align the two or more wing panels with each other for assembly of the UAV.

3 . The ground support system of claim 1 , wherein the at least one or more dollys are further configured to transport the UAV over uneven terrain.

4 . The ground support system of claim 1 , wherein each handling fixture is fitted to a wing panel spar of the at least one wing panel.

5 . The ground support system of claim 1 , wherein the at least one or more handling fixtures further comprise:

one or more wheels attached to a base, wherein the one or more wheels are configured to move each wing panel around for attachment to another wing panel; and

one or more legs attached to the base, wherein the one or more legs are configured to engage with at least one transportation fixture for transporting the UAV, wherein each transportation fixture is configured to load and unload wing panels into a shipping fixture.

6 . The ground support system of claim 1 , wherein the at least one or more handling fixtures allow each wing panel to rotate 360 degrees relative to a ground level.

7 . The ground support system of claim 1 , wherein the at least one or more handling fixtures are height-adjustable to raise or lower the wing panel of the UAV to a desired working height relative to a ground level.

8 . The ground support system of claim 1 , wherein the UAV is secured to the at least one or more dollys via the at least one landing pod of the UAV.

9 . The ground support system of claim 1 , further comprising:

a yoke; and

a winch connecting the yoke to the at least one or more dollys, wherein the UAV is prevented from flying via at least one of: an attachment of the yoke proximate a nose of the landing pod and a ballast weight of the UAV.

10 . The ground support system of claim 9 , further comprising:

a lift tray of the at least one or more dollys, wherein the lift tray cradles the landing pod to further prevent flying of the UAV, wherein the lift tray is configured to lower or raise relative to a ground level, wherein the lift tray positions the wing panel of the UAV at a first pitch angle, wherein the UAV maintains a second pitch angle during flight, wherein the first pitch angle is greater than the second pitch angle, and wherein the first pitch angle decreases a chance that the UAV will unintentionally take flight.

11 . The ground support system of claim 10 , further comprising:

a rear gate of the at least one or more dollys, wherein the rear gate opens for the winch to pull the landing pod into the lift tray via the yoke, and wherein the rear gate closes to secure the landing pod in the lift tray.

12 . The ground support system of claim 10 , wherein the first pitch angle would cause the UAV to stall if the UAV takes off unintentionally.

13 . The ground support system of claim 10 , wherein the first pitch angle is about 14°, and wherein the second pitch angle is about 10°.

14 . The ground support system of claim 1 , further comprising:

at least one interconnect frame connected between each dolly, wherein each interconnect frame stabilizes the UAV after assembly and during transportation of the UAV;

a towing frame connector configured to connect to the at least one interconnect frame, wherein the towing frame connector is configured to connect to a vehicle such that the vehicle can tow the UAV to a runway site; and

a wind fence attached to the vehicle, wherein the wind fence comprises a porous screen that protects the UAV from high winds during towing and allows for faster towing speeds.

15 . The ground support system of claim 14 , wherein the UAV is towed sideways by the vehicle.

16 . The ground support system of claim 14 , wherein the UAV is towed by the vehicle in a first direction, wherein the first direction is perpendicular to a forward direction of flight of the UAV, and wherein towing in the first direction decreases a chance that the UAV will unintentionally take flight.

17 . A method for ground support for an unmanned aerial vehicle (UAV) comprising:

supporting at least one wing panel of the UAV by at least one or more handling fixtures;

receiving at least one landing pod of the UAV by at least one or more dollys, wherein each landing pod supports at least one wing panel of the UAV; and

aligning two or more wing panels with each other for assembly of the UAV by at least one or more of: the at least one or more handling fixtures and the at least one or more dollys.

18 . The method of claim 17 , wherein aligning the two or more wing panels with each other for assembly of the UAV further comprises: moving and rotating the two or more wing panels by the at least one or more handling fixtures and the at least one or more dollys.

19 . The method of claim 17 further comprising:

transporting the UAV over uneven terrain by the at least one or more dollys.

20 . The method of claim 17 further comprising:

raising the wing panel of the UAV by the at least one or more handling fixtures to a desired working height relative to a ground level; and

lowering the wing panel of the UAV by the at least one or more handling fixtures to a desired working height relative to a ground level.
