Abstract

An aircraft system includes a wing member and a plurality of unmanned aircraft systems selectively connectable to the wing member. The wing member has a generally airfoil cross-section, a leading edge and a trailing edge. The unmanned aircraft systems have a connected flight mode while coupled to the wing member and an independent flight mode when detached from the wing member. In the connected flight mode, the unmanned aircraft systems are operable to provide propulsion to the wing member to enable flight. The unmanned aircraft systems are operable to be launched from the wing member to perform aerial missions in the independent flight mode and are operable to be recovered by the wing member and returned to the connected flight mode. Thereafter, in the connected flight mode, the unmanned aircraft systems are operable to be resupplied by the wing member.

First claim

What is claimed is:

1. An aircraft system comprising:
a wing member having an airfoil cross-section, a leading edge and a trailing edge; and
a plurality of unmanned aircraft systems selectively connectable to the wing member, the unmanned aircraft systems having a connected flight mode in which the unmanned aircraft systems are connected to the leading edge of the wing member and an independent flight mode,
wherein, in the connected flight mode, the unmanned aircraft systems are operable to provide propulsion to the wing member to enable flight;
wherein, the unmanned aircraft systems are operable to be launched from the wing member to perform aerial missions in the independent flight mode;
wherein, the unmanned aircraft systems are operable to be recovered by the wing member and returned to the connected flight mode; and
wherein, in the connected flight mode, the unmanned aircraft systems are operable to be resupplied by the wing member.

2. The system as recited in claim 1 further comprising a fuselage connected to and extending generally perpendicular to the wing member.

3. The system as recited in claim 1 wherein the wing member further comprises a flight control system operable to control the unmanned aircraft systems in the connected flight mode.

4. The system as recited in claim 1 wherein each of the unmanned aircraft systems further comprises a flight control system operable to control the respective unmanned aircraft system in the independent flight mode.

5. The system as recited in claim 1 wherein the unmanned aircraft systems provide vertical thrust for the aircraft system in a vertical takeoff and landing flight mode.

6. The system as recited in claim 1 wherein the unmanned aircraft systems provide forward thrust for the aircraft system in a runway takeoff and landing mode.

7. The system as recited in claim 1 wherein the unmanned aircraft systems provide forward thrust for the aircraft system in a forward flight mode.

8. The system as recited in claim 1 wherein the unmanned aircraft systems are magnetically coupled to the wing member in the connected flight mode.

9. The system as recited in claim 1 further comprising electrical connections between the unmanned aircraft systems and the wing member in the connected flight mode.

10. The system as recited in claim 1 further comprising data connections between the unmanned aircraft systems and the wing member in the connected flight mode.

11. The system as recited in claim 1 wherein the wing member further comprises a battery system operable to electrically recharge the unmanned aircraft systems in the connected flight mode.

12. The system as recited in claim 11 wherein the wing member further comprises a battery recharging system selected from the group consisting of a solar energy collection system and a liquid fuel driven generator system.

13. A method of operating an aircraft system including a wing member having an airfoil cross-section, a leading edge and a trailing edge and a plurality of unmanned aircraft systems selectively connectable with the wing member, the method comprising:
providing forward thrust for the aircraft system with the unmanned aircraft systems in a connected flight mode in which the unmanned aircraft systems are connected to the leading edge of the wing member;
launching a first group of the unmanned aircraft systems from the wing member while maintaining a second group of the unmanned aircraft systems in the connected flight mode;
performing aerial missions detached from the wing member with the first group of unmanned aircraft systems in an independent flight mode;
recovering the first group of the unmanned aircraft systems with the wing member and reestablishing the connected flight mode; and
resupplying the first group of the unmanned aircraft systems from the wing member after reestablishing the connected flight mode.

14. The method as recited in claim 13 further comprising relaunching the first group of the unmanned aircraft systems from the wing member after resupplying.

15. The method as recited in claim 13 further comprising launching the second group of the unmanned aircraft systems from the wing member while maintaining the first group of the unmanned aircraft systems in the connected flight mode.

16. The method as recited in claim 13 further comprising controlling the operation of the unmanned aircraft systems in the connected flight mode with a flight control system of the wing member.

17. The method as recited in claim 13 further comprising providing vertical thrust for a vertical takeoff and landing flight mode of the aircraft system with the unmanned aircraft systems in the connected flight mode.

18. The method as recited in claim 13 wherein resupplying the first group of the unmanned aircraft systems from the wing member after reestablishing the connected flight mode further comprises electrically recharging the first group of the unmanned aircraft systems from a battery system of the wing member and providing mission information to the first group of the unmanned aircraft systems from a mission control system of the wing member.

19. The method as recited in claim 13 wherein recovering the first group of the unmanned aircraft systems with the wing member and reestablishing the connected flight mode further comprises magnetically coupling the first group of the unmanned aircraft systems to the wing member, establishing electrical communication between the first group of the unmanned aircraft systems and the wing member and establishing data communication between the first group of the unmanned aircraft systems and the wing member.
