Abstract
A damping system includes a spool about which a tension line is wound. The line's first end is coupled to a first structure subject to forces causing unwanted movement thereof. A damper is coupled to a second structure not subject to the unwanted movement of the first structure. The damper is coupled to the spool for engagement with the spool to slow a rotational speed thereof when the spool rotates in a first direction. The damper is disengaged from the spool when the spool rotates in a second direction in opposition to the first direction. A device, coupled to the line's second end and to the second structure, applies a tension force to the line's second end. The tension force is exceeded when the first structure moves to place the line in tension, and is not exceeded when the first structure moves to place the line in compression.
