UAV arresting hook for use with UAV recovery system
First Claim
1. An apparatus comprising an arresting hook, wherein said arresting hook comprises:
- an arm;
a plurality of latches, wherein said plurality of latches depend from said arm;
an arrangement for coupling said arm to a surface, wherein said arrangement provides said arm with;
a first rotational degree of freedom, wherein said first rotational degree of freedom enables an end of said arm to rotate away from said surface; and
a second rotational degree of freedom, wherein said second degree of freedom enables said arm to rotate about its longitudinal axis.

Abstract
A UAV arresting hook is disclosed. The arresting hook facilitates the capture of a UAV via a UAV recovery system. In the illustrative embodiment, the arresting hook has a rotation block, an arm, and a plurality of latches that are disposed on the arm. The arm is coupled to the UAV via the rotation block, which provides two rotational degrees of freedom to the arm. In a stowed position, the arm is flush against the surface of the UAV. To deploy the arm, a free end of the arm is rotated away from the surface of the UAV. The arm is additionally biased to rotate about its longitudinal axis as it rotates away from the surface of the UAV. This rotation positions the latches to capture an arresting line that is part of a UAV recovery system.
