ABSTRACT:
A retainer made from a shape memory alloy (SMA) is utilized in a separation device that is particularly useful for space applications. Upon being heated to a restoration temperature, the retainer changes from a constricted state to an expanded state. In its constricted state, the retainer surrounds and captures a plurality of securing segments to secure an object. To release the secured object, the retainer is heated to its restoration temperature with an electrical heater, causing the retainer to return to its expanded state and allow the securing segments to move apart and release the secured object.
