Abstract

For retrieval of a hovering aircraft, a cable, bar, or similar fixture is suspended in an approximately horizontal orientation across the retrieval area between two well-separated supports. The aircraft slowly flies into this fixture, which then slides along the aircraft in a direction approximately parallel with the aircraft'"'"'s thrust line. This leads to the aircraft becoming fastened to the fixture by an interceptor or aircraft capturer, which in alternative embodiments are respectively on the aircraft or the fixture or both. Thrust is then reduced, and the aircraft comes to rest hanging from the fixture for subsequent removal. Retrieval is thus accomplished with simple and economical apparatus, light and unobtrusive elements on the aircraft, low risk of damage, and only moderate piloting accuracy.

Claims

1. An apparatus for capturing a flying object in principally thrust-borne flight, said capturing apparatus including:

(a) a fixture;

(b) suspension support configured to suspend the fixture; and

(c) a docking fixture attached to the suspension support, the docking fixture including an arm configured to engage a portion of a flying object;

wherein the suspension support is configured to suspend the fixture such that the flying object in principally thrust-borne flight can;

(i) cause a fixture interceptor of the flying object to contact the fixture and become removably attached to the fixture, and

(ii) after the fixture interceptor is removably attached to the fixture, translate relative to the fixture toward the docking fixture.

2. The apparatus of claim 1, wherein the docking fixture is configured to enable the flying object to be stowed.

3. The apparatus of claim 1, wherein the docking fixture is configured to enable the flying object to be serviced.

4. The apparatus of claim 1, wherein the docking fixture is configured to facilitate launch of the flying object.

5. The apparatus of claim 1, wherein the docking fixture is configured to guide the flying object into a desired resting position as the flying object translates relative to the fixture toward the docking fixture.

6. The apparatus of claim 1, wherein the fixture is selected from the group consisting of:

a rope, a cable, and a bar.

7. The apparatus of claim 1, wherein the docking fixture extends upward from the suspension support.

8. The apparatus of claim 1, wherein the docking fixture is configured to orient the flying object.

9. The apparatus of claim 1, wherein the arm is configured to hold said portion of the flying object.

10. The apparatus of claim 1, which is attached to a movable vehicle.
