ABSTRACT:
A cold-launch uses shape-memory-alloy (“SMA”) actuators to accelerate materiel to a required launch velocity. The SMA actuators are arranged into one or more actuation stages. SMA actuators within a given actuation stage are simultaneously triggered. Actuation stages, however, are triggered sequentially, each triggering adding to the velocity of the materiel.
