Current Space Systems/Loral satellites are powered by solar arrays that are initially folded and secured against the side of the satellite by pretensioned rods. Upon reaching orbit, knives driven by small explosive charges cut each rod, allowing for solar array deployment. However, the sudden release of the tension in the rods produces undesirable shock. The team has been asked to design a lower-shock alternative to the current retention and release design.
