Abstract

Methods and apparatuses for launching, capturing, and storing unmanned aircraft and other flight devices or projectiles are described. In one embodiment, the aircraft can be assembled from a container with little or no manual engagement by an operator. The container can include a guide structure to control motion of the aircraft components. The aircraft can be launched from an apparatus that includes an extendable boom. The boom can be extended to deploy a recovery line to capture the aircraft in flight. The aircraft can then be returned to its launch platform, disassembled, and stored in the container, again with little or no direct manual contact between the operator and the aircraft.

detaching the lifting surface from the aircraft by slidably moving the gripper along the guide path from a first position with the lifting surface attached to the aircraft to a second position with the lifting surface detached from the aircraft.

11. The method of claim 1 wherein removing the lifting surface of the aircraft includes:

translating and rotating the movable portion of the storage apparatus relative to the lifting surface of the aircraft to align a gripper carried by the movable portion with the lifting surface;

contacting and releasably engaging the gripper with the lifting surface; and

detaching the lifting surface from the aircraft by slidably moving the gripper along a guide path of the movable portion from a first position with the lifting surface attached to the aircraft to a second position with the lifting surface detached from the aircraft.

12. The method of claim 1, further comprising servicing the aircraft after releasably securing the aircraft to the storage apparatus.

13. A method for handling an unmanned aircraft, comprising:

deploying a flexible recovery line from an extendable boom mounted at least proximate to a support platform;

releasably capturing a first lifting surface portion of the aircraft in flight with the flexible recovery line;

while the first lifting surface portion of the aircraft is releasably coupled to the flexible recovery line, securing a second lifting surface portion of the aircraft to the support platform;

releasably securing at least a portion of a fuselage of the aircraft to a storage container;

releasing the aircraft from the flexible recovery line and the support platform;

removing at least one of the lifting surfaces of the aircraft using a movable portion of the storage container; and

at least partially enclosing the aircraft in the storage container.

14. The method of claim 13 wherein the aircraft includes a capture device mounted to the lifting surface, and wherein releasably capturing the aircraft in flight includes releasably capturing a portion of the recovery line with the capture device.

15. The method of claim 13, further comprising retracting at least a portion of the extendable boom after releasably capturing the aircraft and before releasably securing the second lifting surface portion of the aircraft to the support platform.

16. The method of claim 13 wherein at least a portion of the storage container is pivotally mounted to the support platform, and wherein releasably securing the aircraft to the storage container includes pivoting at least a portion of the storage container from the support platform to contact a fuselage of the aircraft.

17.
