Unmanned aerial vehicle (UAV) tethered wing recovery

1. An apparatus comprising:

a detachable portion of a wing that is couplable to a fixed portion of the wing, wherein the detachable portion defines a distal end of the wing when the detachable and fixed portions are coupled;

a lock configured to fasten the detachable portion to the fixed portion, wherein the lock is configured to disengage the detachable portion from the fixed portion upon contact of the wing with a recovery device; and

a tether configured to extend between the detachable and fixed portions.

2. The apparatus as defined in claim 1 , further including a guide configured to guide a relative alignment of the detachable portion to the fixed portion when the detachable portion is coupled to the fixed portion.

3. An apparatus as defined in claim 2 , wherein the guide functions as a structural member of the wing to transfer flight loads from the fixed portion to the detachable portion.

4. The apparatus as defined in claim 2 , wherein the guide is located on one of the detachable or fixed portions and has a trapezoidal shape to be received by a corresponding aperture of the other one of the detachable or fixed portions.

5. The apparatus as defined in claim 2 , wherein the tether is contained within a cavity of the guide when the detachable and fixed portions are coupled.

6. The apparatus as defined in claim 1 , wherein the tether includes an elastic cable.

7. An apparatus comprising:

a detachable portion of a wing that is couplable to a fixed portion of the wing;

a lock configured to fasten the detachable portion to the fixed portion, wherein the lock is configured to disengage the detachable portion from the fixed portion upon contact of the wing with a recovery device, and wherein the lock includes a pin; and

a tether configured to extend between the detachable and fixed portions.

8. An apparatus comprising:

a detachable portion of a wing that is couplable to a fixed portion of the wing;

a lock configured to fasten the detachable portion to the fixed portion, wherein the lock is configured to disengage the detachable portion from the fixed portion upon contact of the wing with a recovery device, and wherein the lock includes a coil spring of one of the detachable or fixed portions, and wherein the coil spring is configured to be received by a curved annular surface of the other one of the detachable or fixed portions; and

a tether configured to extend between the detachable and fixed portions.

9. An aircraft comprising:

a wing having a detachable portion couplable to a fixed portion;

a lock configured to couple the detachable portion and the fixed portion, wherein the lock is configured to enable the detachable portion to disengage from the fixed portion when the wing contacts a recovery device; and

a tether configured to extend between the detachable portion and the fixed portion.

10. The aircraft as defined in claim 9 , further including a guide configured to guide a position of the detachable portion relative to the fixed portion when the detachable portion is coupled to the fixed portion.

11. The aircraft as defined in claim 10 , wherein the tether is contained within a cavity of the guide when the detachable and fixed portions are coupled.

12. The aircraft as defined in claim 9 , wherein an end of the fixed portion is located at a fuselage of the aircraft.

13. The aircraft as defined in claim 9 , wherein the lock includes a pin to be disposed in a barrel nut.

14. The aircraft as defined in claim 9 , wherein the lock includes a coil spring of one of the detachable or fixed portions configured to be received by a curved annular surface of the other one of the detachable or fixed portions.

15. A method comprising:

directing a detachable portion of a wing of an aircraft toward a recovery device; and

separating the detachable portion from a fixed portion of the wing upon contact of the wing with the recovery device, wherein a tether extends between the detachable portion and the fixed portion.

16. The method as defined in claim 15 , further including coupling the detachable portion to the fixed portion via a lock.

17. The method as defined in claim 16 , wherein the lock is frangible.

18. The method as defined in claim 15 , wherein separating the detachable portion from the fixed portion includes breaking a pin disposed in a barrel nut.

19. The method as defined in claim 15 , wherein separating the detachable portion from the fixed portion includes separating a coil spring of one of the detachable or fixed portions from a curved annular surface of the other one of the detachable or fixed portions.

20. The method as defined in claim 15 , wherein directing the detachable portion of the wing of the aircraft toward the recovery device includes directing a distal end of the detachable portion toward the recovery device.
