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. A method for capturing a flying object in principally thrust-borne flight, said method comprising:

(a) receiving a portion of the flying object in a docking fixture after;

(i) a fixture interceptor of the flying object contacts a fixture by motion of the flying object relative to the fixture;

(ii) the fixture interceptor removably attaches to the fixture; and

(iii) the flying object translates relative to the fixture toward the docking fixture; and

(b) engaging said portion of the flying object with an arm of the docking fixture.

2. The method of claim 1, which includes stowing the flying object after the docking fixture receives said portion of the flying object.

3. The method of claim 1, which includes servicing the flying object after the docking fixture receives said portion of the flying object.

4. The method of claim 3, wherein said servicing is performed automatically.

5. The method of claim 1, which includes facilitating launch of the flying object after the docking fixture receives said portion of the flying object.

6. The method of claim 1, which includes holding said portion of the flying object with the arm.

7. The method of claim 1, which includes guiding the flying object into a desired resting position as the flying object translates relative to the fixture toward the docking fixture.

8. The method of claim 7, which includes detecting that the flying object has been guided into said desired resting position.

9. The method of claim 1, which includes orienting the flying object after the docking fixture receives said portion of the flying object.
