Abstract

An inflight connection system for aircraft having at least one wing with a wingtip includes, for each aircraft, a primary connector selectively extendable from the wingtip, an alignment connector selectively extendable from the wingtip and a male and female connector assembly disposed proximate the wingtip. The primary connectors extend a greater distance from the wingtips than the alignment connectors such that the primary connectors form a first connection between the aircraft when the aircraft are flying in a connection pattern. Thereafter, retraction of the primary connectors reduces wingtip separation of the aircraft such that the alignment connectors form a second connection between the aircraft establishing coarse alignment therebetween. Thereafter, retraction of the primary and alignment connectors further reduces wingtip separation of the aircraft such that the male and female connector assemblies form a third connection between the aircraft establishing fine alignment therebetween.

First claim

What is claimed is:

1. An inflight connection system for first and second aircraft each having at least one wing with a wingtip, for each aircraft, the system comprising:
a primary connector including a primary conical receptacle and a primary conical connector, the primary conical connector selectively extendable from the primary conical receptacle relative to the wingtip;
an alignment connector including an alignment conical receptacle and an alignment conical connector, the alignment conical connector selectively extendable from the alignment conical receptacle relative to the wingtip; and
at least one male and female connector assembly disposed proximate the wingtip,
wherein, the primary conical connectors extend a greater distance from the wingtips than the alignment conical connectors such that the primary conical connectors form a first connection between the first and second aircraft when the first and second aircraft are flying in a connection pattern;
wherein, after the first connection, retraction of the primary conical connectors reduces wingtip separation of the first and second aircraft such that the alignment conical connectors form a second connection between the first and second aircraft establishing coarse alignment therebetween; and
wherein, after the second connection, retraction of the primary and alignment conical connectors into the respective primary and alignment conical receptacles further reduces wingtip separation of the first and second aircraft such that the at least one male and female connector assemblies form a third connection between the first and second aircraft establishing fine alignment therebetween.

2. The system as recited in claim 1 wherein the primary and alignment conical connectors further comprise magnetic connectors.

3. The system as recited in claim 1 wherein the primary and alignment conical connectors further comprise electromagnetic connectors.

4. The system as recited in claim 1 wherein the primary and alignment connectors further comprise semi-rigid extension members respectively coupled to the primary and alignment conical connectors.

5. The system as recited in claim 4 wherein the semi-rigid extension members are formed from a material selected from the group consisting of fiberglass and carbon.

6. The system as recited in claim 4 wherein the primary and alignment connectors are operably coupled to linear actuators operable to extend and retract the primary and alignment conical connectors via the semi-rigid extension members.

7. The system as recited in claim 1 wherein at least a portion of the at least one male and female connector assembly of each aircraft is rotatable to threadably couple the first and second aircraft together wingtip-to-wingtip.

8. The system as recited in claim 1 wherein, after the third connection, retraction of the primary and alignment conical connectors securably couples the first and second aircraft together wingtip-to-wingtip.

9. The system as recited in claim 1 wherein the at least one male and female connector assembly of each aircraft further comprises a locking member that securably couples the first and second aircraft together wingtip-to-wingtip.

10. The system as recited in claim 1 wherein each aircraft further comprises at least two male and female connector assemblies.

11. An inflight connection system for aircraft, the system comprising:
first and second aircraft each having at least one wing with a wingtip, the first and second aircraft each including:
a primary connector including a primary conical receptacle and a primary conical connector, the primary conical connector selectively extendable from the primary conical receptacle relative to the wingtip;
an alignment connector including an alignment conical receptacle and an alignment conical connector, the alignment conical connector selectively extendable from the alignment conical receptacle relative to the wingtip; and
at least one male and female connector assembly disposed proximate the wingtip,
wherein, the primary conical connectors extend a greater distance from the wingtips than the alignment conical connectors such that the primary conical connectors form a first connection between the first and second aircraft when the first and second aircraft are flying in a connection pattern;
wherein, retraction of the primary conical connectors reduces wingtip separation of the first and second aircraft such that the alignment conical connectors form a second connection between the first and second aircraft establishing coarse alignment therebetween; and
wherein, retraction of the primary and alignment conical connectors into the respective primary and alignment conical receptacles further reduces wingtip separation of the first and second aircraft such that the at least one male and female connector assemblies form a third connection between the first and second aircraft establishing fine alignment therebetween.

12. The system as recited in claim 11 wherein the primary and alignment conical connectors further comprise magnetic connectors.

13. The system as recited in claim 11 wherein the primary and alignment connectors further comprise semi-rigid extension members respectively coupled to the primary and alignment conical connectors.

14. The system as recited in claim 11 wherein, after the third connection, retraction of the primary and alignment conical connectors securably couples the first and second aircraft together wingtip-to-wingtip.

15. The system as recited in claim 11 wherein the at least one male and female connector assembly of each aircraft further comprises a locking member that securably couples the first and second aircraft together wingtip-to-wingtip.

16. A method for inflight connection of aircraft having at least one wing with a wingtip, the method comprising:
flying first and second aircraft in a connection pattern;
extending a primary conical connector from a primary conical receptacle relative to the wingtips of the first and second aircraft;
extending an alignment conical connector from an alignment conical receptacle relative to the wingtips of the first and second aircraft;
forming a first connection between the first and second aircraft with the primary conical connectors of the first and second aircraft;
retracting the primary conical connectors to reduce wingtip separation of the first and second aircraft;
forming a second connection between the first and second aircraft with the alignment conical connectors of the first and second aircraft to establish coarse alignment therebetween;
retracting the primary and alignment conical connectors into the respective primary and alignment conical receptacles to further reduce wingtip separation of the first and second aircraft; and
forming a third connection between the first and second aircraft with male and female connector assemblies of the first and second aircraft to establish fine alignment therebetween.

17. A method as recited in claim 16 wherein forming the first connection between the first and second aircraft with the primary conical connectors of the first and second aircraft further comprises magnetically forming the first connection.

18. A method as recited in claim 16 wherein forming the second connection between the first and second aircraft with the alignment conical connectors of the first and second aircraft further comprises magnetically forming the second connection.

19. A method as recited in claim 16 further comprising, after forming the third connection, retracting the p
