Abstract

Various embodiments of the present disclosure provide an apparatus configured to automatically retrieve, service, and launch an aircraft. For retrieval, the aircraft drops a weighted cable, and pulls it at low relative speed into a broad aperture of the apparatus. In certain instances, the cable is dragged along guiding surfaces of the apparatus into and through a slot until its free end is captured. The aircraft becomes anchored to the apparatus, and is pulled downward by the cable into a receptacle. Guiding surfaces of the receptacle adjust the position and orientation of a probe on the aircraft, directing the probe to mate with a docking fixture of the apparatus. Once mated, the aircraft is automatically shut down and serviced. When desired, the aircraft is automatically started and tested in preparation for launch, and then released into free flight. A full ground-handling cycle is thus accomplished with a simple, economical apparatus.

Claims

1. An apparatus for retrieving a flying object from free flight, said apparatus comprising:

(a) a base; and

(b) a docking station supported by the base and configured to receive a portion of the flying object, the docking station including;

(i) a member holder configured to receive a member connected to a body of the flying object and hold the member after receiving the member, and

(ii) a member mover configured to move the member relative to the docking station to cause the flying object to move toward the docking station.

2. The apparatus of claim 1, wherein the member mover is configured to move the member relative to the docking station until the docking station receives the portion of the flying object.

3. The apparatus of claim 2, wherein the docking station includes a sensor configured to detect when the docking station receives the portion of the flying object, and wherein the member mover is configured to stop moving the member relative to the docking station when the sensor detects that the docking station receives the portion of the flying object.

4. The apparatus of claim 1 wherein the member is flexible.

5. The apparatus of claim 1, wherein the docking station includes at least one locking device configured to secure the flying object after the docking station receives the portion of the flying object.

6. The apparatus of claim 1, wherein the docking station includes at e one connector configured to service the flying object.

7. The apparatus of claim 6, wherein the docking station is configured to automatically service the flying object using the at least one connector.

8. The apparatus of claim 1, wherein the docking station includes at east one launch orienting device configured to facilitate launch of the flying object.

9. The apparatus of claim 1, which includes a measuring device configured ensure a three-dimensional position of the flying object relative to the apparatus.

10. The apparatus of claim 1, which includes a measuring device configured to measure an orientation of the flying object relative to the apparatus.

11. The apparatus of claim 1, wherein the member holder is configured to release the member to facilitate launch of the flying object.

12. An apparatus for retrieving a flying object from free flight, said apparatus comprising:

(a) a base; and

(b) a docking station supported by the base and configured to receive a portion of the flying object, the docking station including;

(i) a member holder configured to receive a flexible member connected to a body of the flying object and hold the member after receiving the member, and

(ii) a member mover configured to move the member relative to the docking station until the docking station receives the portion of the flying object.

13. The apparatus of claim 12, wherein the docking station includes a sensor configured to detect when the docking station receives the portion of the flying object, and wherein the member mover is configured to stop moving the member relative to the docking station when the sensor detects that the docking station receives the portion of the flying object.

14. The apparatus of claim 12, wherein the docking station includes at least one locking device configured to secure the flying object after the docking station receives the portion of the flying object.

15. The apparatus of claim 12, wherein the docking station includes one connector configured to service the flying object.

16. The apparatus of claim 15, wherein the docking station is configured to automatically service the flying object using the at least one connector.

17. The apparatus of claim 15, wherein the docking station includes at least one launch orienting device configured to facilitate launch of the flying object.

18. The apparatus of claim 15, which includes a measuring device configured to measure a three-dimensional position of the flying object relative to the apparatus.

19. The apparatus of claim 15, which includes a measuring device configured to measure an orientation of the flying object relative to the apparatus.

20. The apparatus of claim 15, wherein the member holder is configured to release the member to facilitate launch of the flying object.
