ABSTRACT:
Embodiments of the present invention are directed to a compact and lightweight, automated latching device which includes a passive catch configured to be engaged with a motor-powered latch to form a mechanical connection between two structure in a precise and repeatable manner. An active damping mechanism is used to dissipate any vibrational energy that may be present in the latched structure. The apparatus may be used to precisely orient and attach a deployable element, usually of a space vehicle, to the main body of the vehicle. In one embodiment, a latching apparatus comprises a catch having a catch body and a probe connected to the catch body. A latch has a main housing and a grip mechanism movable relative to the main housing. The grip mechanism is configured to grip the probe and to be actuatable to pull the probe toward the latch. A damping member is coupled with the main housing of the latch, and is movable relative to the main housing of the latch toward the catch. The damping member is actuatable to exert a damping force against the catch body of the catch.
