Abstract

Systems and methods for countering an unmanned air vehicle are disclosed. Representative methods include directing an interceptor UAV toward a target UAV, and directing the interceptor UAV back to ground along a controlled flight path, for example, in response to an instruction not to engage with the target UAV, and/or in response to an unsuccessful engagement. Another representative method includes disabling the target UAV by deploying a disabling element (e.g., a net) from the interceptor UAV to contact the target UAV. Representative systems include a target acquisition system, a launch control system, and an engagement system carried by the interceptor UAV. In particular embodiments, the interceptor UAV can have a generally cylindrical fuselage, one or more fins carried by the fuselage, counter-rotating propellers carried by the fuselage, and a disabling system that is configured to disable the target UAV.

Claims

1. An interceptor UAV system for disabling a target UAV, the system comprising:

an interceptor UAV;

a target acquisition system directable to an airspace to detect, track, or detect and track an incoming target UAV;

a launch control system coupleable to the target acquisition system, the launch control system being programmed with instructions that, when executed, automatically direct the interceptor UAV to launch; and

an engagement system carried by the interceptor UAV and in communication with the target acquisition system, the engagement system being programmed with instructions that, when executed,

(a) direct the interceptor UAV to the target UAV; and

(b) direct the interceptor UAV to land if the interceptor UAV does not successfully disable the target UAV.

2. The interceptor UAV system of claim 1 wherein the interceptor UAV is:

a flight vehicle having;

a generally cylindrical fuselage;

a fin carried by the fuselage;

a propulsion system that includes;

a first propeller;

a second propeller; and

a power source coupled to the first and second propellers to rotate the first propeller in a first direction and rotate the second propeller in a second direction opposite the first direction;

at least one control surface;

a guidance system carried by the flight vehicle and coupled to the at least one control surface; and

a disabling system carried by the flight vehicle and having a first, inactive mode and a second, active mode, wherein in the second mode, the disabling system is positioned to disable the target UAV.

3. The interceptor UAV system of claim 2 wherein the guidance system is configured to direct the vehicle along a controlled flight path to ground.

4. The interceptor UAV system of claim 2 wherein the guidance system is configured to direct the vehicle along a controlled flight path to ground upon receiving at least one of the following indications:

(a) an indication to not engage with the target UAV;

or

(b) an indication that the interceptor UAV did not sufficiently disable the target UAV.

5. The interceptor UAV system of claim 2 wherein the fin is one of four fins arranged in a cruciform shape.

6. The interceptor UAV system of claim 2 wherein the fin is one of three fins.

7. The interceptor UAV system of claim 1 wherein the interceptor UAV includes:

a flight vehicle having;

a cylindrical fuselage elongated along a fuselage axis;

four fins carried by the fuselage and arranged in a cruciform, each fin having a fin slot extending from the fuselage in an outboard direction transverse to the fuselage axis;

a propulsion system that includes;

a first propeller carried by the fuselage and rotatable about the fuselage axis in a first direction to sequentially pass in and out of successive fin slots;

a second propeller carried by the fuselage and rotatable about the fuselage axis in a second direction opposite the first direction to sequentially pass in and out of the successive fin slots;

a power source carried by the fuselage, the power source including a first electric motor coupled to the first propeller to rotate the first propeller in the first direction, and a second electric motor coupled to the second propeller to rotate the second propeller in the second direction; and

a stored electrical energy source coupled to the first and second electric motors;

at least one control surface carried by at least one of the fins;

a guidance system coupled to the at least one control surface; and

a deployable net carried by the flight vehicle and having a first, inactive mode and a second, active mode, wherein in the second mode, the deployable net is deployed from the flight vehicle to disable the target UAV.

8. The interceptor UAV system of claim 7 wherein the net is configured to detach from the interceptor UAV after deploying.

9. The interceptor UAV system of claim 7 wherein the net is configured to remain attached to the interceptor UAV after deploying.

10. The interceptor UAV system of claim 7 wherein the stored energy source includes a single source for both the first and second motors.

11. The interceptor UAV system of claim 7 wherein the stored energy source includes a first source for the first motor and a second source for the second motor.

12. The interceptor UAV system of claim 1, further comprising a disablement system carried by the interceptor UAV and being activatable to disable the target UAV.

13. The interceptor UAV system of claim 12 wherein the disablement system includes a deployable net.

14. The interceptor UAV system of claim 1 wherein the interceptor UAV includes:

a generally cylindrical fuselage;

a fin carried by the fuselage; and

a propulsion system that includes;

a first propeller;

a second propeller; and

a power source coupled to the first and second propellers to rotate the first propeller in a first direction and rotate the second propeller in a second direction opposite the first.

15. The interceptor UAV system of claim 1 wherein the target acquisition system includes a radar scanner, and wherein the interceptor UAV system further comprises:

a ground-based targeting radar system coupleable to the scanner to

(a) receive a location and track of the target UAV; and

(b) determine an interception track for the interceptor UAV;

a ground-based optics system coupleable to the ground-based targeting radar system to acquire a first image of the target UAV; and

an interceptor optics system carried by the interceptor UAV and positionable to acquire a second image of the target UAV.

16. The interceptor UAV system of claim 15 wherein the engagement system is programmed to automatically direct an engagement flight path or a non-engagement flight path based on a comparison of the first and second images.

17. The interceptor UAV system of claim 1 wherein the interceptor UAV is a first interceptor UAV and wherein the launch control system includes instructions that, when executed, automatically direct a second interceptor UAV to launch before the first interceptor UAV disables the target UAV.

18. The interceptor UAV system of claim 1 wherein the engagement system is programmed with instructions that, when executed, direct the interceptor UAV to disable the target UAV.

19. The interceptor UAV system of claim 1 wherein the engagement system is programmed with instructions that, when executed, direct the interceptor UAV to disable the target UAV by striking the UAV.

20. The interceptor UAV system of claim 1 wherein the engagement system is programmed with instructions that, when executed, direct the interceptor UAV to land if the target UAV has already been disabled by another interceptor UAV.

21. The interceptor UAV system of claim 1 wherein the engagement system is programmed with instructions that, when executed, direct the interceptor UAV to land after the target UAV has been disabled by the interceptor UAV.
