Abstract:
1. An SMA actuator, operated by an enemy source, the SMA actuator comprising: an SMA element having a first end, a second end, and a central portion therebetween, the SMA element being oriented so that the first and second ends are adjacent one another and attached to one of an anchor interface or payload interface, and so that the central portion of the SMA element is attached to the other of the anchor interface or the payload interface; and an electrical shorting device electrically connecting the first and second ends, whereby when an electrical potential is provided by the energy source to the SMA element between a first point located between the first end and the central portion and a second point located between the second end and the central portion, the electrical potential will be distributed substantially equally between the first and second points causing the SMA element to activate reducing the length of the SMA element.
