Multicopter-assisted system and method for launching and retrieving a fixed-wing aircraft
The present disclosure provides various embodiments of a multicopter-assisted launch and retrieval system generally including: (1) a multi-rotor modular multicopter attachable to (and detachable from) a fixed-wing aircraft to facilitate launch of the fixed-wing aircraft into wing-borne flight; (2) a storage and launch system usable to store the modular multicopter and to facilitate launch of the fixed-wing aircraft into wing-borne flight; and (3) an anchor system usable (along with the multicopter and a flexible capture member) to retrieve the fixed-wing aircraft from wing-borne flight.
1. A rotorcraft-assisted system for retrieving an aircraft from flight, the system comprising:
a rotorcraft;
a flexible capture member having a first end and a second end, the first end attachable to the rotorcraft; and
an anchor system including a base, a breakaway device removably attachable to the base, and a flexible capture member payout and retract device rotatably attachable to the base,
wherein the second end of the flexible capture member is attachable to the flexible capture member payout and retract device,
wherein the flexible capture member is attachable to the breakaway device between the ends of the flexible capture member.
2. The rotorcraft-assisted system of claim 1 , wherein the flexible capture member includes a capture portion including two ends and a middle extending between the two ends, one of the two ends being thicker than the middle.
3. The rotorcraft-assisted system of claim 2 , wherein both ends of the capture portion are thicker than the middle.
4. The rotorcraft-assisted system of claim 3 , wherein the two ends of the capture portion each include a Brummel eye splice.
5. The rotorcraft-assisted system of claim 1 , wherein the flexible capture member includes an elastic portion near the first end.
6. The rotorcraft-assisted system of claim 5 , wherein the flexible capture member includes a capture portion and a retractable portion, the capture portion located between the elastic portion and the retractable portion.
7. The rotorcraft-assisted system of claim 6 , wherein the capture portion includes two ends and a middle extending between the two ends, one of the two ends being thicker than the middle.
8. The rotorcraft-assisted system of claim 7 , wherein both ends of the capture portion are thicker than the middle.
9. The rotorcraft-assisted system of claim 1 , wherein the flexible capture member includes an elastic portion near the first end, wherein the flexible capture member includes a capture portion and a retractable portion, the capture portion located between the elastic portion and the retractable portion, wherein the capture portion includes two ends and a middle extending between the two ends, wherein both ends of the capture portion are thicker than the middle, and wherein the two ends of the capture portion each include a Brummel eye splice.
10. The rotorcraft-assisted system of claim 1 , which includes a ring, the ring attachable to the flexible capture member to enable the flexible capture member to be attached to the breakaway device.
11. A flexible capture member for retrieving an aircraft from flight, the flexible capture member comprising:
an elastic portion including a compliant damper;
a retractable portion; and
a capture portion between the elastic portion and the retractable portion.
12. The flexible capture member of claim 11 , wherein the capture portion includes two ends and a middle extending between the two ends, one of the two ends being thicker than the middle.
13. The flexible capture member of claim 12 , wherein both of the ends of the capture portion are thicker than the middle.
14. The flexible capture member of claim 13 , wherein the two ends each include a Brummel eye splice.
15. The flexible capture member of claim 11 , wherein the retractable portion is non-elastic, and wherein the capture portion is non-elastic.
16. A flexible capture member for retrieving an aircraft from flight, the flexible capture member comprising:
an elastic portion;
a retractable portion including an elastic member; and
a capture portion between the elastic portion and the retractable portion.
17. The flexible capture member of claim 16 , wherein the retractable portion includes the elastic member and a non-elastic member, and wherein the elastic member is positioned inside the non-elastic member.
18. The flexible capture member of claim 16 , wherein the retractable portion includes the elastic member and a non-elastic member, and wherein the elastic member is positioned inside the non-elastic member, and wherein the capture portion is non-elastic.
