Abstract

A test stand for an unmanned aerial vehicle comprising: a base arranged to make contact with the ground; a frame extending from the base, the frame comprising at least a first side portion and a second side portion that define a space therebetween; and a mount slidably attached to the frame within the space, the mount configured to affix to an unmanned aerial vehicle such that the mount and the unmanned aerial vehicle slide within the defined space in a direction parallel to the frame during a test flight.

Claims (29)

1. A test stand for an unmanned aerial vehicle comprising:

a base arranged to make contact with the ground;

a frame extending from the base, the frame comprising at least a first side portion and a second side portion that define a space therebetween;

one or more mounting mechanism slidably attached to the frame, the one or more mounting mechanism configured to affix to an unmanned aerial vehicle such that the unmanned aerial vehicle is permitted to slide within the defined space in a direction parallel to the frame during a test flight; and

a cross beam affixed to a top end of the first side portion and a top end of the second side portion such that the defined space is below the cross beam.

2. The test stand of claim 1 , wherein the base comprises a plurality of legs.

3. The test stand of claim 2 , wherein the plurality of legs reside parallel to the ground.

4. The test stand of claim 2 , wherein the plurality of legs form angles with the ground such that bottom ends of the plurality of legs make contact with the ground and top ends of the plurality of legs are affixed to the frame.

5. The test stand of claim 1 , wherein each of the one or more mounting mechanism comprises:

a wheel that is configured to reside in a respective track formed in the frame; and

a fastener that is configured to affix the wheel to a corresponding clearance hole in the unmanned aerial vehicle.

6. The test stand of claim 1 , wherein the one or more mounting mechanism comprises a mount.

7. The test stand of claim 6 , wherein the mount comprises at least a first aperture within which the first side portion of the frame resides and a second aperture within which the second side portion of the frame resides.

8. The test stand of claim 6 , wherein the mount comprises clips that are configured to attach to receiving mechanisms on the unmanned aerial vehicle.

9. The test stand of claim 6 , wherein the mount comprises a docking device that is configured to releasably attach to the unmanned aerial vehicle.

10. The test stand of claim 6 , wherein one or both of the mount and the unmanned aerial vehicle comprises one or more feet configured to dampen a collision with the ground.

11. The test stand of claim 10 , wherein the feet comprise one or more springs.

12. The test stand of claim 10 , wherein the feet comprise a force-absorbing material.

13. The test stand of claim 1 , wherein the first side portion comprises two beams that extend from the base and the second side portion comprises two beams that extend from the base.

14. The test stand of claim 1 , wherein the frame comprises one or more additional side portions that further define the space.

15. The test stand of claim 1 , wherein the test stand is configured to attach to other test stands to form a test stand system for testing flights of a plurality of unmanned aerial vehicles.

16. A test stand system for a plurality of unmanned aerial vehicles comprising:

a plurality of test stands each comprising:

a base arranged to make contact with the ground;

a frame extending from the base, the frame comprising at least a first side portion and a second side portion that define a space therebetween;

one or more mounting mechanism slidably attached to the frame, the one or more mounting mechanism configured to affix to an unmanned aerial vehicle such that the unmanned aerial vehicle is permitted to slide in a direction parallel to the frame during a test flight; and

a cross beam affixed to a top end of the first side portion and a top end of the second side portion such that the defined space is below the cross beam,

wherein each base comprises one or more mechanisms for fixing the bases of the plurality of test stands together.

17. The test stand system of claim 16 , further comprising a plurality of joists that each connects the cross beam of one of the test stands to the cross beam of another one of the test stands.
