Abstract

An aircraft for capturing drones includes an airframe having a drone channel with first and second wings extending outboard thereof. A two-dimensional distributed thrust array includes a plurality of propulsion assemblies coupled to each of the first and second wings such that the rotor disc of each propulsion assembly is outboard of the drone channel. A flight control system is coupled to the airframe and is operable to independently control each of the propulsion assemblies. A mesh bag is coupled to the drone channel forming a drone capture net. The aircraft is configured to convert between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation. The aircraft is also configured to overtake a drone during flight in the biplane orientation such that the drone passes through the drone channel into the mesh bag, thereby capturing the drone in the drone capture net.

First claim

What is claimed is:

1. An aircraft for capturing a drone, the aircraft comprising:
an airframe having a drone channel with first and second wings extending outboard thereof;
a two-dimensional distributed thrust array attached to the airframe, the thrust array including a plurality of propulsion assemblies coupled to the first wing and a plurality of propulsion assemblies coupled to the second wing such that a rotor disc of each propulsion assembly is outboard of the drone channel;
a flight control system coupled to the airframe and operable to independently control each of the propulsion assemblies; and
a mesh bag coupled to the drone channel forming a drone capture net;
wherein, the aircraft is configured to convert between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation; and
wherein, the aircraft is configured to overtake the drone during flight in the biplane orientation such that the drone passes through the drone channel into the mesh bag, thereby capturing the drone in the drone capture net.

2. The aircraft as recited in claim 1 wherein the drone channel has a regular convex polygon shaped perimeter.

3. The aircraft as recited in claim 1 wherein the drone channel has a rectangular shaped perimeter.

4. The aircraft as recited in claim 1 wherein the drone channel has a square shaped perimeter.

5. The aircraft as recited in claim 1 wherein the drone channel has a circular shaped perimeter.

6. The aircraft as recited in claim 1 wherein the first and second wings are parallel to each other.

7. The aircraft as recited in claim 1 wherein the first wing has a starboard wing section extending from a starboard side of the drone channel and a port wing section extending from a port side of the drone channel and wherein the second wing has a starboard wing section extending from the starboard side of the drone channel and a port wing section extending from the port side of the drone channel.

8. The aircraft as recited in claim 1 wherein at least a portion of the first wing forms a portion of the drone channel and wherein at least a portion of the second wing forms a portion of the drone channel.

9. The aircraft as recited in claim 8 wherein each of the wings includes a polygon section.

10. The aircraft as recited in claim 8 wherein each of the wings includes an arcuate section.

11. The aircraft as recited in claim 1 wherein the mesh bag further comprises a filament matrix with open spaces configured to allow air to pass therethrough during flight.

12. The aircraft as recited in claim 1 wherein the mesh bag is configured to disable rotary operations of the drone after capturing the drone.

13. The aircraft as recited in claim 1 wherein the mesh bag further comprises a releasable mesh bag that is configured to be jettisoned from the drone channel after capturing the drone.

14. An aircraft for capturing a drone, the aircraft comprising:
an airframe having first and second wings with first and second pylons extending therebetween forming a drone channel;
a two-dimensional distributed thrust array attached to the airframe, the thrust array including a plurality of propulsion assemblies coupled to the first wing and a plurality of propulsion assemblies coupled to the second wing such that a rotor disc of each propulsion assembly is outboard of the drone channel;
a flight control system coupled to the airframe and operable to independently control each of the propulsion assemblies; and
a mesh bag coupled to the drone channel forming a drone capture net;
wherein, the aircraft is configured to convert between thrust-borne lift in a VTOL orientation and wing-borne lift in a biplane orientation; and
wherein, the aircraft is configured to overtake the drone during flight in the biplane orientation such that the drone passes through the drone channel into the mesh bag, thereby capturing the drone in the drone capture net.

15. The aircraft as recited in claim 14 wherein the drone channel has a perimeter shape selected from the group consisting of regular convex polygons, rectangles, squares or circles.

16. The aircraft as recited in claim 14 wherein the first and second wings are parallel to each other and wherein the first and second pylons are parallel to each other such that the drone channel has a rectangular shaped perimeter.

17. The aircraft as recited in claim 14 wherein each of the wings includes a polygon section and wherein each of the pylons has a polygon section such that the drone channel has a regular convex polygon shaped perimeter.

18. The aircraft as recited in claim 14 wherein each of the wings includes an arcuate section and wherein each of the pylons has an arcuate section such that the drone channel has a circular shaped perimeter.

19. The aircraft as recited in claim 14 wherein the mesh bag further comprises a filament matrix with open spaces configured to allow air to pass therethrough during flight and configured to disable rotary operations of the drone after capturing the drone.

20. The aircraft as recited in claim 14 wherein the mesh bag further comprises a releasable mesh bag that is configured to be jettisoned from the drone channel after capturing the drone.
