Abstract

A system for neutralization of a target aerial vehicle comprises a plurality of counter-attack unmanned aerial vehicles (UAVs) and an aerial vehicle detection system comprising at least one detection sensor operable to detect the target aerial vehicle in flight. The system also comprises an aerial vehicle capture countermeasure in the form of a net tethering the plurality of counter-attack UAVs to one another. The counter-attack UAV(s) are operable to capture and neutralize the target aerial vehicle with the net. The system can comprise at least one net storage device associated with a structure and configured to store at least a portion of the net when in a stowed position, and to facilitate deployment of the net when moved to a deployed position via coordinated flight of the plurality of counter-attack UAVs based on the detected target aerial vehicle.

First claim

What is claimed is:

1. A system for neutralization of a target aerial vehicle, comprising:
one or more counter-attack unmanned aerial vehicles (UAVs);
an aerial vehicle detection system comprising at least one detection sensor operable to detect a target aerial vehicle in flight, and operable to provide command data associated with the detected target aerial vehicle to the one or more counter-attack UAVs; and
an aerial vehicle capture countermeasure tethering the one or more counter-attack UAVs at at least a first tethering point and a second tethering point of a structure,
wherein, in response to receiving the command data, the one or more counter-attack UAVs are operable to move the aerial vehicle capture countermeasure from a stowed position to a deployed position to capture the target aerial vehicle.

2. The system of claim 1 , wherein the each of the one or more counter-attack UAVs comprises a flight body and a flight control system supported about the flight body, the flight control system operable to facilitate flight of the counter-attack UAVs.

3. The system of claim 2 , wherein each of the one or more counter-attack UAVs comprises at least one on-board sensor configured to detect a position of the target aerial vehicle, and wherein the flight control system comprises a flight controller operable to control autonomous flight of the counter-attack UAV based on the detected position of the target aerial vehicle.

4. The system of claim 3 , wherein the at least one on-board sensor comprises a camera movably coupled to the flight body and operable to modify a pointing position of the camera according to the detected position of the target aerial vehicle.

5. The system of claim 1 , wherein the aerial vehicle detection system comprises an external aerial vehicle detection system associated with a ground-based structure to monitor an airspace, wherein the at least one detection sensor comprises a plurality of detection sensors configured to detect a plurality of target aerial vehicles.

6. The system of claim 1 , further comprising a plurality of counter-attack UAVs tethered to the structure by the aerial vehicle capture countermeasure, wherein each counter-attack UAV comprises a communication device communicatively coupled to other communication devices of the other counter-attack UAV(s) to communicate respective positions of the plurality of counter-attack UAVs to facilitate coordinated flight of the plurality of counter-attack UAVs.

7. The system of claim 1 , wherein the aerial vehicle capture countermeasure comprises at least one flexible entangling element configured to disrupt operation of at least one rotary propeller device of the target aerial vehicle.

8. The system of claim 7 , wherein the at least one flexible entangling element comprises at least one of a net, filament, monofilament, braided filament, tendril, fiber, string, cord, strand, thread, rope, or wire.

9. The system of claim 1 , wherein each of the one or more counter-attack UAVs is electrically coupled to an external power source for powering the one or more counter-attack UAVs.

10. The system of claim 1 , wherein the aerial vehicle capture countermeasure comprises a net.

11. The system of claim 10 , wherein the net is configured to be moveable from a stowed position to a deployed position in response to flight of the one or more counter-attack UAVs.

12. The system of claim 11 , further comprising at least one storage device associated with the structure and configured to store at least a portion of the net when in the stowed position, and to facilitate deployment of the net when moved to the deployed position.

13. The system of claim 10 , further comprising at least one drum reel device associated with the structure, the at least one drum reel device coupled to the net by a retractable tether and operable to facilitate deployment of the net via the retractable tether when moved to the deployed position.

14. The system of claim 10 , further comprising a plurality of counter-attack UAVs tethered to the structure by the net, wherein the plurality of counter-attack UAVs are operable in a coordinated manner to move the net, after being moved to the deployed position, to a capture position based on the position of the detected target aerial vehicle.

15. The system of claim 10 , further comprising at least one dynamic net support mechanism associated with the structure and coupled to the net, the at least one dynamic net support mechanism operable to move in a first direction relative to the structure, such that the net and the counter-attack UAVs move with the at least one dynamic net support mechanism.

16. The system of claim 15 , further comprising a rail system associated with the structure, wherein the at least one dynamic net support mechanism comprises at least two net support mechanisms movable in a coordinated manner along the rail system.

17. The system of claim 15 , further comprising a plurality of counter-attack UAVs tethered to the net and operable in coordinated manner to move the net in a second direction different from the first direction.

18. The system of claim 10 , further comprising a plurality of counter-attack UAVs tethered to the net and operable in a coordinated manner to support the net in the deployed position to define a perimeter net area.

19. The system of claim 18 , further comprising at least one external power source electrically coupled to each of the counter-attack UAVs to facilitate extended flight time and to maintain the perimeter net area.

20. The system of claim 1 , wherein the command data comprises at least one of aerial vehicle capture countermeasure deployment command data, target aerial vehicle detection data, counter-attack UAV control data, or a combination thereof.

21. A method for neutralization of a target aerial vehicle, comprising:
detecting a target aerial vehicle in flight;
operating one or more counter-attack unmanned aerial vehicles (UAVs) to maintain an aerial vehicle capture countermeasure in a deployed position, the aerial vehicle capture countermeasure tethering the one or more counter-attack UAVs at at least a first tethering point and a second tethering point of a structure; and
capturing the target aerial vehicle with the aerial vehicle capture countermeasure.

22. The method of claim 21 , wherein detecting the target aerial vehicle further comprises tracking a dynamic flight position with an aerial vehicle detection system.

23. The method of claim 21 , wherein operating one or more counter-attack UAVs comprises operating a plurality of counter-attack UAVs, the method further comprising communicating position data to the plurality of counter-attack UAVs to facilitate coordinated flight, the plurality of counter-attack UAVs tethered together by the aerial vehicle capture countermeasure.
